Drug and food interactions
ribavirin food
Applies to: Virazole (ribavirin)
Food can enhance the levels of ribavirin in your body. Ribavirin should be taken with food or just after eating. This will make it easier for your body to absorb the medication. Do not take it on an empty stomach. Swallow the tablet or capsule whole.
efavirenz food
Applies to: Atripla (efavirenz / emtricitabine / tenofovir disoproxil)
Taking efavirenz with food increases the amount of medicine in your body, which may increase the frequency of side effects. You should take efavirenz once a day on an empty stomach, preferably at bedtime. Taking it at bedtime may make some side effects such as dizziness, trouble sleeping, drowsiness, trouble concentrating, and/or unusual dreams less bothersome. However, these symptoms may be more severe if efavirenz is used with alcohol or mood-altering (street) drugs. You should avoid driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
