Efavirenz is an antiretroviral agent that blocks the viral replication. It is used to decrease the amount of viruses (viral load) to as low as possible, for as long as possible.
Common side effects that may occur are:
Inform your doctor if the side effects become severe and bothersome. Report to your doctor immediately if you/your child experiences any of the following symptoms:
Efavirenz may affect the cholesterol level and liver enzymes level. Your doctor will routinely monitor the levels prior to the treatment initiation and while you/your child is on this medication.
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.
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.
Some medication may reduce its efficacy, or increase its toxicity. Do not take or give your child any other medications or herbal products without first consulting your doctor.
