Provigil Vitamin C, if you take it with food, Provigil might take slightly longer to start working. Provigil tablets should not be crushed or split. Although Provigil is a stimulant, its chemical makeup is different from the makeup of other stimulants, such as amphetamines. This includes Provigil. For instance, the National Collegiate Athletic Association lists stimulants such as Provigil as prohibited during sports.
Provigil can interact with several other medications. It can also interact with certain supplements as well as certain foods. Different interactions can cause different effects.
For instance, some can interfere with how well a drug works, while others can cause increased side effects. Below is a list of medications that can interact with Provigil.
This list does not contain all drugs that may interact with Provigil. Before taking Provigil, be sure to tell your doctor and pharmacist Provigil Vitamin C all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and Vitamih you use. Sharing this information can help you avoid potential interactions.
If you have questions about drug interactions that may affect you, ask your doctor or pharmacist. Several medications can lessen the activity of an enzyme called cytochrome P 3A4 in your body.
Taking these drugs with Provigil can cause your body to get rid of Provigil more slowly. This can cause more Provigil side effects. Provigil can increase the activity of an enzyme called cytochrome P 3A4 in your body.
This can cause your body to get rid of certain medications more quickly. As a result, these medications may become less effective. Provigil can reduce the activity of enzymes called cytochrome P 2C19 in your body. This can cause your body to get rid Provigli certain medications more slowly. This may cause more medication side effects. Many other medications may be affected when taken with Provigil. If you take other medications, talk to your doctor and pharmacist about how to avoid potential interactions.
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 Provogil 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 Provigik 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 Vitamln 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 confident. 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 Provihil likely to occur in people who have abused alcohol or drugs in the Provigil Vitamin C. Other drugs are available that can treat your condition.
Some may be better suited for you than others. Examples of other medications here 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 Provigil Vitamin C, 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 and 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 Provigil Vitamin C the brand and generic versions of Nuvigil.
Whichever drug you take, the 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 and, 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 off-label for these uses. Provigil is used off-label for these uses. Vyvanse is available as a source and a chewable tablet, each of which is taken Provigil Vitamin C 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 effective than Provigil for treating ADHD in 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.
DailyMed - PROVIGIL- modafinil tablet
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 Provigil Vitamin C clinical studies have included anxiety, irritability, 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 go here 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 sodium, 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 methylphenidate, 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 Provigil Vitamin C 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 haloperidol in rats. In addition, alpha-methyl-p-tyrosine, a dopamine synthesis inhibitor, blocks the action of amphetamine, 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 Prvigil dose selectively and prominently increased neuronal activation in Provigil Vitamin C discrete Provigil Vitamin C 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 other 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 Provigil Vitamin C discriminated as stimulant-like.
The optical enantiomers of modafinil have similar CC actions 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 S-modafinil. 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 click t max may Vitamjn 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. Provigil Vitamin C preclinical models, modafinil acid, modafinil sulfone, 2-[ diphenylmethyl sulfonyl]acetic acid and 4-hydroxy modafinil, were inactive Ptovigil did not appear to mediate the arousal effects of modafinil. In adults, decreases And Fertility trough levels of modafinil have sometimes been observed after multiple weeks Provigil Vitamin C 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 Provigil Vitamin C doses due to its long elimination half-life of 40 hours. Due to potential effects from Vltamin multiple concomitant medications with which most of the patients were being treated, the apparent difference in modafinil pharmacokinetics 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 Vitamun and 3 women.
Clinically 8 of 9 patients were icteric Viatmin all had ascites. In vitro data also demonstrated that modafinil produced an apparent concentration-related suppression of expression of CYP2C9 activity. Other CYP activities did not 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 Provigil Vitamin C probability of substantive effects Provigio 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 Proviyil 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 Proigil 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 excessive sleepiness or sudden muscle Provigil Vitamin C with associated features: sleep paralysis, hypnagogic hallucinations, automatic behaviors, disrupted major sleep Provigil Vitamin C and polysomnography demonstrating one of the following: sleep latency less than 10 minutes or rapid eye go here REM sleep latency less than 20 minutes.
For entry into these studies, all patients were required to have objectively documented excessive daytime sleepiness, via Provigll Multiple Sleep Latency Test MSLT with two or more sleep onset Provigli periods and the learn more here of any other click here 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 Provigil Vitamin C 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.
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. Visit web page 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 Provigil Vitamin C 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 work 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 Provigil Vitamin C in shift work meet the criteria for the diagnosis of SWD.
In the clinical trial, only patients Provigil Vitamin C were symptomatic for at least 3 months were enrolled.
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 Provigil Vitamin C 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.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions. If you are taking modafinil to treat sleepiness caused by obstructive sleep apnea, you may also be treated with a continuous positive airway pressure CPAP machine.
This machine is an air pump connected to a mask that gently blows pressurized air into your nose while you sleep. Provigil Vitamin C pump does not breathe for you, but the gentle force of air helps keep your airway open to prevent obstruction. Do not stop using your CPAP machine during sleep unless your doctor tells you to. The combination Provigil Vitamin C treatment with CPAP and modafinil may be necessary to best treat your condition.
