Drug Interactions
Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: alpha blockers (e.g., doxazosin, prazosin), medications for high blood pressure (e.g., beta blockers such as atenolol/metoprolol, clonidine, guanabenz, methyldopa), "blood thinners" (e.g., warfarin), MAO inhibitors (e.g., furazolidone, isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine), street drugs (e.g., methamphetamine, MDMA/"ecstasy"), drugs that affect liver enzymes that remove armodafinil from the body (e.g., azole antifungals such as itraconazole/ketoconazole, erythromycin, rifamycins such as rifabutin/rifampin, anti-seizure medications such as carbamazepine/phenobarbital). Armodafinil can speed up or slow down the removal of other drugs from your body by affecting certain liver enzymes. These affected drugs may include clomipramine, cyclosporine, diazepam, ethinyl estradiol, omeprazole, phenytoin, propranolol, triazolam. This medication may decrease the effectiveness of hormonal birth control (e.g., pills, patch, ring). This effect can result in pregnancy. You may need to use an additional form of reliable birth control while using this medication and for 1 month after stopping this medication. Consult your doctor or pharmacist for details. Check the labels on all your medicines (e.g., cough-and-cold products, diet aids) because they may contain ingredients (e.g., pseudoephedrine, ephedra/ma huang) that could increase your heart rate or blood pressure. Ask your pharmacist about using those products safely. Avoid drinking large amounts of beverages containing caffeine (e.g., coffee, tea, certain soft drinks). Caffeine can increase the side effects of this medication. This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
