Efavirenz - Dosage and How to Use

How should Efavirenz be used?

​Efavirenz is usually taken once daily. It is usually given in combination with other antiretroviral agents to achieve significant decrease in viral multiplication.

Efavirenz should be taken on an empty stomach (1 hour before or 2 hours after meals), preferably at bedtime. Do not crush or chew the tablet.

What should I do if I miss a dose?

​Missing doses make Efavirenz less effective and may also make the virus resistant to Efavirenz and other possible antiretroviral agents. This could make the virus harder to treat.

If you forgot to take or give your child the medication, give the dose as soon as you remember and then continue as per normal. Otherwise, if it is close to the time for your/your child’s next dose, skip the missed dose and give the next dose at the usual time. Do not double or increase the dose.

If you/your child vomits within 15 minutes of administration, give another dose if possible.

What should I do if I overdose?
