What this medicine is used for
The name of your medicine is Nevirapine XR APOTEX modified release tablets. It contains the active ingredient nevirapine anhydrous.
It is used to treat infection by the Human Immunodeficiency Virus (HIV-1). HIV-1 is the main virus responsible for the development of Acquired Immunodeficiency Syndrome (AIDS).
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Nevirapine belongs to a group of antiretroviral medicines called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by inhibiting or interrupting the enzyme reverse transcriptase that the HIV virus needs to multiply.
Nevirapine does not cure or prevent HIV-1 infection or AIDS, but it does hinder the growth of HIV-1.
Nevirapine is prescribed in combination with other antiretroviral medicines which hinder the growth of HIV-1 in other ways. When these medicines are taken with nevirapine the growth of HIV-1 is hindered more effectively.
Nevirapine has not been shown to reduce the likelihood that you will develop the illnesses associated with advanced HIV-1 infection. It is important for you to continue seeing your doctor regularly.
Nevirapine does NOT reduce or prevent transmission of HIV-1 to others through sexual contact or blood contamination.
Use in children
Do not give this medicine to a child under the age of 3 years.
Safety and effectiveness in children younger than 3 years have not been established.

How to take this medicine
Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
Follow the dosing instructions carefully, especially the once daily dosage during the first 14 days ('lead-in' period) using nevirapine immediate release tablets or oral solution (available from alternative brands).
Adults 16 years and older:
First 14 days: 200 mg immediate-release nevirapine taken once daily (an alternative brand is required for the first 14 days).
After the first 14 days: one Nevirapine XR APOTEX 400 mg modified release tablet once daily (taken at about the same time each day).
Children (aged 3 years or older) and adolescents to 15 years:
Nevirapine modified release tablets can be taken by children aged 3 years or older able to tolerate tablets. Your child's doctor will decide the most appropriate nevirapine formulation for your child and will calculate the dose they need. The calculation will include your child's age and body weight, or body surface area.
Ask your doctor if you are not sure what dose to give your child.
Your doctor will closely monitor you or your child for potential side effects of taking the medicine, in particular during the first 18 weeks of treatment.
If you are switching from immediate-release tablets or oral suspension to modified-release tablets:
If you are already taking 200 mg immediate-release tablets or oral suspension twice daily in combination with other antiretroviral agents you can switch to Nevirapine XR APOTEX 400 mg modified-release tablets once daily without the 14 day 'lead-in' period.
