There are no factors that are known to predict the risk of occurrence or the severity of rash associated with modafinil. Drugs that are largely eliminated via CYP2C19 metabolism, such as diazepam, propranolol, phenytoin (also via CYP2C9) or S-mephenytoin may have prolonged elimination upon coadministration with PROVIGIL and may require dosage reduction and monitoring for toxicity. Such off-label use is not illegal, as doctors are free to prescribed approved drugs in any way they see fit. General Considerations Dosage adjustment should be considered for concomitant medications that are substrates for CYP3A4, such as triazolam provigil lamictal interaction and cyclosporine (See PRECAUTIONS, Drug Interactions). 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 and medication called provigil ). 2 Dosage in Shift Work Disorder (SWD) The recommended dosage of PROVIGIL for patients with SWD is 200 mg taken orally once a day as a single dose approximately 1 hour prior to the start of their work shift.

Approved by the FDA in 1998, has been used to treat the excessive sleepiness associated with narcolepsy, obstructive sleep apnea/hypopnea syndrome, and shift work sleep disorder. 3)]. , eosinophilia, leukopenia, thrombocytopenia), pruritus, and asthenia.  The new Provigil labeling cautions physicians against prescribing the drug to people with a history of mania or depression, provigil warnings and says that ‘Provigil’ use should be halted if a patient develops any psychiatric symptoms. G. 2. Multi-organ Hypersensitivity Reactions Multi-organ hypersensitivity reactions, including at least one fatality in postmarketing experience, have occurred in close temporal association (median time to detection 13 days: range 4-33) to the initiation of modafinil. The FDA has warned that Provigil use has been connected to severe psychiatric symptoms In addition to the skin disorders, the FDA has warned that Provigil use has been connected to severe psychiatric symptoms, including anxiety, mania, hallucinations, and suicidal thoughts. The new Provigil warnings say that the drug has been associated with a number of serious skin provigil warnings disorders, including Stevens-Johnson Syndrome, a sometimes life-threatening hypersensitivity complex affecting the skin and the mucous membrane. Although there have been a limited number of reports, multi-organ hypersensitivity reactions may result in best site to buy provigil hospitalization or be life-threatening. In elderly patients, elimination of PROVIGIL and its metabolites may be reduced as a consequence of aging. Rare cases of serious or life-threatening rash, including SJS, Toxic Epidermal Necrolysis (TEN), and Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) have been reported in adults and children in worldwide post-marketing experience. Drugs that are largely eliminated via CYP2C19 metabolism, such as diazepam, propranolol, phenytoin (also via CYP2C9) or S-mephenytoin may have prolonged elimination upon coadministration with PROVIGIL and may require dosage reduction and monitoring for toxicity. If PROVIGIL is used adjunctively with CPAP, the encouragement of and periodic assessment of CPAP compliance is necessary. 2. There are no factors that are known to predict the risk of occurrence or the severity of multi-organ hypersensitivity reactions associated with modafinil. Therefore, consideration should be given to the use of lower doses in this population (See CLINICAL PHARMACOLOGYandPRECAUTIONS). Other associated manifestations included myocarditis, hepatitis, liver function test abnormalities, hematological abnormalities (e.  The military sometimes uses Provigil to keep pilots and soldiers awake during combat situations, and the drug is known to enhance short-term memory. Signs and symptoms of this disorder were diverse; however, patients typically, although not exclusively, presented with fever and rash associated with other organ system involvement. 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 CLINICAL PHARMACOLOGY and PRECAUTIONS). CLINICAL PHARMACOLOGYPRECAUTIONS In elderly patients, elimination of PROVIGIL and its metabolites may be reduced as a consequence of aging. There is inadequate information to determine safety and efficacy of dosing in patients with severe renal impairment (See CLINICAL PHARMACOLOGYandPRECAUTIONS). Accordingly, duration of therapy cannot be relied upon as a means to predict the potential risk heralded by the first appearance of a rash. The military sometimes uses Provigil to keep pilots and soldiers awake during combat situations, and the drug is known to enhance short-term memory. provigil for chronic fatigue
