Lamivudine is usually taken twice daily. It is usually given in combination with at least two other antiretroviral agents to achieve significant decrease in viral multiplication.
Lamivudine can be administered with or without food.
Missing doses makes Lamivudine less effective and may also make the virus resistant to Lamivudine and other possible antiretroviral agents.
If you forgot take the medication within 4 hours, administer it as soon as you remember and then continue to take it as per normal. Otherwise, skip the missed dose and administer the next dose at the usual time. Do not double or increase the dose.
If you or your child vomits within 15 minutes of administration, give another dose if possible.
