To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.
Do not take this medication with other products that contain efavirenz.
Other medications can affect the removal of efavirenz from your body, which may affect how efavirenz works. Examples include some drugs used to treat seizures (such as carbamazepine, phenobarbital, phenytoin), rifamycins (such as rifampin), St. John's wort, among others.
Efavirenz can speed up or slow down the removal of many other medications from your body, which may affect how they work. Examples of affected drugs include some drugs for anxiety/sleep (such as alprazolam, midazolam, triazolam), azole antifungals (such as itraconazole, ketoconazole, voriconazole), bupropion, calcium channel blockers (such as diltiazem, verapamil), cisapride, ergot drugs (such as ergotamine), macrolide antibiotics (such as clarithromycin), methadone, pimozide, rifabutin, sertraline, some cholesterol-lowering statins (such as atorvastatin, pravastatin, simvastatin), warfarin, among others.
Some other drugs to treat HIV infection (such as other NNRTIs including etravirine/nevirapine/rilpivirine) may also interact with efavirenz. If you are taking atazanavir with this medication, you may need to also take another medication (ritonavir). Consult your doctor or pharmacist for more details.
This medication may decrease the effectiveness of hormonal birth control such as pills, patch, or ring. This could cause pregnancy. However, to reduce the risk of spreading HIV to others, always use barrier protections during all sexual activity. (See also Precautions section.)
Tell your doctor or pharmacist if you are taking other products that cause drowsiness including alcohol, antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as diazepam, zolpidem), muscle relaxants, and narcotic pain relievers (such as codeine).
Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
