Taking Provigil with monoamine oxidase inhibitors MAOIs might lead to dangerous side effects such as very high blood pressure, chest pain, severe headache, and increased body temperature. Provigil should not be taken within 14 days of using an MAOI. Taking Provigil with warfarin Coumadin, Jantoven may make your body get rid of warfarin more slowly. This may increase the effects of warfarin and increase your risk of side effects such as bleeding.

Provigil may interact with certain supplements or herbal products you may be taking. Examples of these include:. Taking Provigil with marijuana might change how marijuana affects you. Provigil alters enzymes in your body that control how quickly the body gets rid of marijuana chemicals that cause you to get high. This might increase or decrease the effects and side effects of marijuana. Drinking certain fruit juices, such as grapefruit juice and orange juice, while taking Provigil might change how your body handles the drug.

This could increase the amount of Provigil in your body and increase your risk of side effects. Caffeine in foods and beverages might add to the stimulant effects of Provigil. This can increase the risk of stimulant-related side effects such as anxiety, nervousness, trouble sleeping, and others. Alcohol can make you feel tired and sleepy.

This can decrease the effects of Provigil, which is typically used to help you feel less tired and sleepy. Some people who take Provigil can have changes in mood or thinking that makes them feel more focused and more Thw. Although not common, some people may also experience feelings of euphoria. This effect can lead to misuse or abuse of Provigil for nonmedical uses.

Abuse or misuse is more likely to occur in people who have abused alcohol or drugs in the past. Other drugs are available that can treat your condition. Some may be better suited for you than Ta,e. Examples of other medications that can be used to decrease daytime sleepiness in people with narcolepsy, sleep apnea, or shift work sleep disorder include:.

You may wonder how Provigil compares to certain drugs such as Nuvigil. Provigil and Nuvigil are very similar medications. That means that their chemical makeup is virtually identical, but the chemicals are arranged slightly differently.

Provigil and Nuvigil are considered first-choice medication options for decreasing sleepiness in people with narcolepsy, sleep apnea, and shift work sleep disorder. That said, an analysis of clinical studies indicates that Provigil and Nuvigil might work about equally well for reducing sleepiness for people with sleep apnea.

Provigil Provigul Nuvigil are both brand-name drugs. The generic name of Nuvigil is armodafinil. Generic drugs are typically less expensive than brand-name drugs. The brand and generic versions of Provigil appear to be more expensive than the brand and generic versions of Nuvigil. Whichever drug you take, Besy amount you pay will depend on your health insurance plan. You may wonder how Provigil compares to certain drugs such as Vyvanse. Provigil and Vyvanse lisdexamfetamine are both stimulant medications, but they affect the brain in slightly different ways.

Provigil increases wakefulness and alertness. Vyvanse can cause wakefulness continue reading, in people with attention deficit hyperactivity disorder ADHDcan also produce feelings of calm and focus.

Provigil is FDA-approved for treating daytime sleepiness caused by narcolepsy, sleep apnea, and shift work sleep disorder. Vyvanse is used When Is The Best Time To Take Provigil for When Is The Best Time To Take Provigil uses. Provigil is used off-label for Bes uses.

Vyvanse is available as a capsule and a chewable tablet, each of which is taken once daily. Provigil and Vyvanse are both stimulant medications. As a result, they have several similar side effects. For the treatment of ADHD, these medications have not been directly compared in clinical studies. However, according to an analysis of clinical studies, Vyvanse appears to be more click than Provigil for treating ADHD Provigll adults.

These medications have also not been directly compared in clinical studies looking at decreasing daytime sleepiness in people with narcolepsy or other disorders. Provigil and Vyvanse are brand-name drugs. Provigil is also available in a generic form called modafinil, but Vyvanse is not available as a generic. Provigil costs more than Vyvanse. However, the generic version of Provigil costs less than Vyvanse. The actual amount you pay will depend on your health insurance plan.

The drug works in the brain to increase amounts of certain chemical messengers such as dopamine. It also seems to affect the messenger glutamate in certain areas of the brain. These actions may Iw in stimulation of brain activities, which could make you Tim less tired. Provigil begins to work within 30 to 60 minutes of when you take it. If you take it with food, the drug might take slightly longer to start working.

Some research in animals has shown negative effects to a fetus when the mother takes this drug. Slowed growth of the fetus and spontaneous abortion have occurred in women who took Provigil. This medication should only be used during pregnancy if the benefit justifies the potential risk. If you do take Provigil while pregnant, you can sign up for a registry Ths will help gather information about your experience.

Provigil (Modafinil) - Oral

These include:. Provigil is a stimulant with effects dissimilar compared to other central nervous stimulants such as amphetamine or methylphenidate. Provigil does not have alpha-adrenergic effects, but the alpha-adrenergic antagonist prazosin can decrease the wakefulness effects of Provigil. Provigil dopamine reuptake does not have dopamine receptor agonist activity.

Dopamine antagonists do not block wakefulness from Provigil. Animal studies show that Provigil increases Whrn activity in the thalamus and T. Provigil is readily absorbed when taken orally and reaches peak plasma concentration within 2 to 4 hours. Peak levels may be delayed by about an hour when the drug is taken with food.

Provigil is primarily eliminated via the liver. Provigil induces cytochrome P 3A4 and induces its own metabolism through this route. Provigil is contraindicated in people who have had a hypersensitivity reaction to Provigil or Nuvigil armodafinil in the past.

Provigil is a Schedule IV controlled substance. Studies show that Provigil has the potential to cause euphoric effects and feelings consistent with other stimulants, including When Is The Best Time To Take Provigil. People with a Wyen of alcohol or drug abuse may have a higher risk of abusing Provigil.

The adverse reaction profile was similar across these studies.

Clinical chemistry, hematology, and urinalysis parameters were monitored in the studies. No differences were apparent in alanine aminotransferase ALTaspartate aminotransferase ASTtotal protein, albumin, or total bilirubin.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Alternative or concomitant methods of contraception are recommended for patients taking steroidal contraceptives e. Monitoring of circulating cyclosporine concentrations and appropriate dosage adjustment for cyclosporine should be considered when used concomitantly with PROVIGIL.

Elimination of drugs that are substrates for CYP2C19 e. There are no adequate and well-controlled studies of modafinil in pregnant women. Intrauterine growth restriction and spontaneous abortion have been reported in association with modafinil a mixture of R- and S-modafinil and armodafinil the R-enantiomer of modafinil.

Although the pharmacology of modafinil is not identical to that of the sympathomimetic amines, it does share some pharmacologic properties with this class. Certain of these drugs have been associated with intrauterine growth restriction and spontaneous abortions.

Whether the cases reported with modafinil are drug-related is unknown. In studies of modafinil and armodafinil conducted in rats modafinil, armodafinil and rabbits modafinildevelopmental toxicity was observed at clinically relevant plasma exposures. No effects on postnatal developmental and neurobehavioral parameters were observed in surviving offspring. Healthcare providers are encouraged to register pregnant patients, or pregnant women may enroll themselves in the registry by calling toll free.

It is not known whether modafinil or its metabolites are excreted in human milk. Safety and effectiveness in pediatric patients have not been established. There were no statistically significant differences favoring modafinil over placebo in prolonging sleep latency as measured by MSLT, or in perceptions of sleepiness as determined by the clinical global impression-clinician scale CGI-C.

Transient leukopenia, which resolved without When Is The Best Time To Take Provigil intervention, was also observed. In the controlled Provigill study, 3 of 38 girls, ages 12 or older, treated with modafinil experienced dysmenorrhea compared to 0 of 10 girls who received placebo. There were three 7 to 9 Ti,e, double-blind, placebo-controlled, parallel group studies in children and adolescents aged years with Attention-Deficit Hyperactivity Disorder Tlme.

Although these studies showed statistically significant differences favoring modafinil over placebo in reducing ADHD symptoms as measured by the ADHD-RS school versionthere were 3 cases of serious rash including one case of possible SJS among patients exposed to modafinil in this program. Modafinil is not approved for use in treating ADHD. In clinical When Is The Best Time To Take Provigil, experience in a limited number of modafinil-treated patients who were greater than 65 years of age showed an incidence of adverse reactions similar to other Tue groups.

In elderly patients, elimination of modafinil and its metabolites may be reduced as a consequence of aging. Therefore, consideration should be given to the use of lower doses and close monitoring in this population [see Dosage and Administration 2.

In patients with severe hepatic impairment, the dose of PROVIGIL should be reduced to one-half of that recommended for patients with normal hepatic function [see Dosage and Administration 2. In humans, modafinil produces psychoactive and euphoric effects, alterations in mood, perception, thinking, and feelings typical of other CNS stimulants. In in vitro binding studies, modafinil binds to the dopamine reuptake site and causes an increase in extracellular dopamine, but no increase in dopamine release.

Modafinil is reinforcing, as evidenced by its self-administration in monkeys Provvigil trained to self-administer cocaine. In some studies, modafinil was also partially discriminated as stimulant-like. Patients should be observed for signs of misuse or abuse e. The abuse potential of modafinil, and mg was assessed relative to methylphenidate 45 and 90 mg in an inpatient study in individuals experienced with drugs of abuse.

Results from this clinical study demonstrated that modafinil produced psychoactive and euphoric effects and feelings consistent with other scheduled CNS stimulants methylphenidate. In one placebo-controlled clinical trial, the effects of modafinil withdrawal were monitored following 9 weeks of modafinil use.

There were no reported withdrawal symptoms with modafinil during 14 days of observation, although sleepiness returned in narcoleptic patients.

In addition, several intentional acute overdoses occurred; the two largest being mg and mg taken by two subjects participating in foreign depression studies. None of these study subjects experienced any unexpected or life-threatening effects. Adverse reactions that were reported at these doses included excitation or agitation, insomnia, and slight or moderate elevations in hemodynamic parameters.

Other observed high-dose effects in clinical studies have included anxiety, When Is The Best Time To Take Provigil, aggressiveness, confusion, nervousness, tremor, palpitations, sleep disturbances, nausea, diarrhea, and decreased prothrombin time. From postmarketing experience, there have been reports of fatal overdoses involving modafinil alone or in combination with other drugs. Symptoms most often accompanying PROVIGIL overdose, alone or in combination with other drugs have included insomnia; central nervous system symptoms such as restlessness, disorientation, confusion, agitation, anxiety, excitation, and hallucination; digestive changes such as nausea and diarrhea; and cardiovascular changes such as tachycardia, bradycardia, hypertension, and chest pain.

The child remained stable. The symptoms associated with overdose in children were similar to those observed in adults. Such overdoses should be managed with primarily supportive care, including cardiovascular monitoring. Modafinil is a racemic compound. Modafinil is a white to off-white, crystalline powder that is practically insoluble in water and cyclohexane. It is sparingly to slightly soluble in methanol and acetone. PROVIGIL tablets contain mg or mg of modafinil and the following inactive ingredients: croscarmellose Prkvigil, lactose monohydrate, magnesium stearate, microcrystalline cellulose, povidone, and pregelatinized starch.

The mechanism s through which modafinil promotes wakefulness is unknown. Modafinil has wake-promoting actions similar to sympathomimetic agents including amphetamine and Taje, although the pharmacologic profile is not identical to that of the sympathomimetic amines.

Modafinil is not a direct- or indirect-acting dopamine receptor agonist. However, in vitro, modafinil binds to the dopamine transporter and inhibits dopamine reuptake. This activity has been associated in vivo with increased extracellular dopamine levels in some brain regions of animals. In genetically engineered mice lacking the dopamine transporter DATmodafinil lacked wake-promoting activity, suggesting that this activity was DAT-dependent.

However, the wake-promoting effects of modafinil, unlike those of amphetamine, were not antagonized by the dopamine receptor antagonist Thr in rats. In addition, alpha-methyl-p-tyrosine, a dopamine synthesis inhibitor, blocks the action of Txke, but does not block locomotor activity induced by modafinil.

In the cat, equal wakefulness-promoting doses of methylphenidate and amphetamine increased neuronal activation throughout the brain. Modafinil at an equivalent wakefulness-promoting dose selectively and prominently increased neuronal activation in more discrete regions of the brain. The relationship of this finding in cats to the effects of modafinil in humans is unknown. In addition to its wake-promoting effects and ability to increase locomotor activity in animals, modafinil produces psychoactive and euphoric effects, alterations in mood, perception, thinking, and feelings typical of hWen CNS stimulants in humans.

Modafinil has reinforcing properties, as evidenced by its self-administration in monkeys previously trained to self-administer cocaine; modafinil was also partially discriminated as stimulant-like. The optical enantiomers of modafinil have similar pharmacological Provkgil in animals. Two major metabolites of modafinil, modafinil acid and modafinil sulfone, do not appear to contribute to the CNS-activating properties of modafinil. Modafinil is a racemic compound, whose enantiomers have different pharmacokinetics e.

The enantiomers do not interconvert. At steady state, total exposure to R-modafinil is approximately three times that for Too. The effective elimination half-life of modafinil after multiple doses is about 15 hours. Apparent steady states of total modafinil and R-modafinil are reached after days of dosing. Food has no effect on overall PROVIGIL bioavailability; however, time to reach peak concentration t max may be delayed by approximately one hour if taken with food.

Urine alkalinization has no effect on the elimination of modafinil. Metabolism occurs through hydrolytic deamidation, S-oxidation, aromatic ring hydroxylation, and glucuronide conjugation. The largest fraction of the drug in urine was modafinil acid, but at least six other metabolites were present in lower concentrations.

Only two metabolites reach appreciable concentrations in plasma, i. In preclinical models, modafinil acid, modafinil sulfone, 2-[ diphenylmethyl sulfonyl]acetic acid and 4-hydroxy modafinil, were inactive or did not appear to mediate the arousal effects of modafinil. In adults, decreases in trough levels of modafinil have sometimes been observed after multiple weeks of dosing, suggesting auto-induction, but the magnitude of the decreases and the inconsistency of their occurrence suggest that their clinical significance is minimal.

Significant accumulation of modafinil sulfone has been observed after multiple doses due to its long elimination half-life of 40 hours. Due to potential effects from the multiple concomitant medications with which most of the patients were being treated, the apparent difference in modafinil Tiime may not be attributable solely to the effects of aging. However, the results suggest that the clearance of modafinil may be reduced in the elderly [see Dosage and Administration 2.

The pharmacokinetics and metabolism of modafinil were examined in patients with cirrhosis of the liver 6 men and 3 women. Clinically 8 of 9 patients were icteric and all had ascites. Tine vitro data also demonstrated that modafinil produced an apparent concentration-related suppression of expression of CYP2C9 activity.

Other CYP activities did Tk appear to be affected by modafinil. The existence of multiple pathways for modafinil metabolism, as well as the fact that a non-CYP-related pathway is the most rapid in metabolizing modafinil, suggest that there is a low probability of substantive effects on the overall pharmacokinetic profile of PROVIGIL due to CYP inhibition by concomitant medications.

There was no evidence of tumorigenesis associated with modafinil administration in these studies. However, the mouse study was inadequate because the high dose was not a maximum tolerated dose MTD. Modafinil was negative in a series of in vitro i. The criteria for narcolepsy include either: 1 recurrent daytime naps or lapses into sleep that occur almost daily for at least three months, plus sudden bilateral loss of postural muscle tone in association with intense emotion cataplexy ; or 2 a complaint of Provigli sleepiness or sudden Whsn weakness with associated features: sleep paralysis, hypnagogic hallucinations, automatic behaviors, disrupted major sleep episode; and polysomnography demonstrating one of the following: sleep latency less than 10 minutes or rapid eye movement REM sleep latency less than 20 minutes.

For entry into these Whej, all patients were required to have objectively documented excessive BBest sleepiness, via a Multiple Sleep Latency Test MSLT with two or more sleep onset REM periods and the absence of any other clinically significant active medical or psychiatric disorder. For each test session, the subject was told to lie quietly and attempt to sleep. Each test session was terminated after 20 minutes if no sleep occurred or 15 minutes after sleep onset.

For a successful trial, both measures had to show statistically significant improvement. The MWT measures latency in minutes to sleep onset averaged over 4 test sessions at 2 hour intervals following nocturnal polysomnography. For each test session, the subject was asked to attempt to remain awake without using extraordinary measures. Each test session was terminated after 20 minutes if no sleep occurred or 10 minutes after sleep onset.

Patients were rated by evaluators who had no access to any data about the patients other than a measure of their baseline severity.

Timing. If you're taking Provigil to reduce daytime sleepiness due to narcolepsy or sleep apnea, you'll take it. Dosing · Adults and teenagers 17 years of age and older— milligrams (mg) once a day, in the morning. Your doctor may increase your dose as needed. · Teenagers.

Evaluators were not given any specific guidance about the criteria they were to apply when rating patients. Both studies demonstrated improvement in objective and subjective measures of excessive daytime sleepiness for both the mg and mg doses compared to placebo. The criteria include either: 1 excessive sleepiness or insomnia, plus frequent episodes of impaired breathing during sleep, and associated features such as loud snoring, morning headaches and dry mouth upon awakening; or 2 excessive sleepiness or insomnia and polysomnography demonstrating one of the following: more than five obstructive apneas, each greater than 10 seconds in duration, per hour of sleep and one or more of the following: frequent arousals from sleep associated with the apneas, bradytachycardia, and arterial oxygen desaturation in association with the apneas.

CPAP use continued throughout the study. The primary measure of effectiveness was the change from baseline on the ESS at final visit. At week 4, the ESS was reduced by 4.

All patients met the criteria for chronic SWD. The criteria include: 1 either, a a primary complaint of excessive sleepiness or insomnia which is temporally associated with a work period usually night click that occurs during the habitual sleep phase, or b polysomnography and the MSLT demonstrate loss of a normal sleep-wake pattern i.

It should be noted that not all patients with a complaint of sleepiness who are also engaged in shift work meet the criteria for the diagnosis of SWD. In the clinical trial, only patients who were symptomatic for at least 3 months were When Is The Best Time To Take Provigil. Advise patients to stop taking PROVIGIL and to notify their physician right away if they develop a rash, hives, mouth sores, blisters, peeling skin, trouble swallowing or breathing, or a related allergic phenomenon.

Advise patients not to alter their previous behavior with regard to potentially dangerous activities e. Inform patients that it may be critical that they continue to take their previously prescribed treatments e. Advise patients to stop taking PROVIGIL and contact their physician right away if they experience chest pain, rash, depression, anxiety, or signs of psychosis or mania.

Advise patients to notify their physician if they become pregnant or intend to become pregnant during therapy. Caution patients regarding the potential increased risk of pregnancy when using steroidal contraceptives including depot or implantable contraceptives with PROVIGIL and for one month after discontinuation of therapy.

There may be new information.

The best time to take Provigil is in the morning, because it can make it difficult to fall asleep at night. That said, some people do take it in the evening. For obstructive sleep apnea, take this medication by mouth with or without food as directed by your doctor, usually once daily in the morning. Continue your.
