If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Never take a double dose to make up for it. If you are still in the first 14 days of treatment and you miss several doses, talk to your doctor before continuing.
Always get your nevirapine from a registered pharmacy, never from roadside vendors or unverified sources, as fake ARVs are dangerous. Take your medication every single day at the same time, as missing doses can cause the virus to become resistant, making the drug stop working. Report any rash or yellowing of the eyes to your doctor immediately, especially during the first 18 weeks of treatment.
Nevirapine can reduce the effectiveness of birth control pills and injections, so use condoms as a backup. It interacts with rifampicin (commonly used for TB treatment in Nigeria), so your doctor may need to adjust doses. Avoid taking with St. John's Wort herbal supplements as it can make nevirapine less effective.
