NEVIRAPINE VIATRIS contains the active ingredient nevirapine. Nevirapine belongs to a group of medicines called antiretroviral medicines called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by inhibiting or interrupting with the enzyme reverse transcriptase that the HIV virus needs to multiply.

NEVIRAPINE VIATRIS is used in the treatment of the infection caused by the Human Immunodeficiency Virus (HIV-1). HIV-1 is the main virus responsible for the development of Acquired Immunodeficiency Syndrome (AIDS).

NEVIRAPINE VIATRIS does not cure or prevent HIV-1 infection or AIDS, but it does hinder the growth of HIV-1.

NEVIRAPINE VIATRIS is used in combination with other antiretroviral medicines which hinder the growth of HIV-1 in other ways. When these medicines are taken with NEVIRAPINE VIATRIS, the growth of HIV-1 is hindered more effectively.

NEVIRAPINE VIATRIS 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 VIATRIS does not reduce the risk of or prevent transmission of HIV-1 to others through sexual contact or blood contamination.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Your doctor may have prescribed it for another reason.

  • It does not matter if you take this medicine before or after food.


  • Swallow the tablets whole with a full glass of water.
  • Do not crush or chew the tablets.


  • Continue taking your medicine for as long as your doctor tells you to.
  • This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

If you forget to use NEVIRAPINE VIATRIS

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose you missed.

If you have missed taking NEVIRAPINE VIATRIS for more than 7 days, contact your doctor before you start taking it again.

You may need to restart using the 14 days (lead-in) once daily dosing procedure.

If you take too much NEVIRAPINE VIATRIS

If you think that you have used too much NEVIRAPINE VIATRIS, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Symptoms of an overdose may include:

oedema (an abnormal accumulation of fluid beneath the skin or in one or more cavities of the body), fatigue, fever, headache, insomnia, lung problems, rash, dizziness, nausea, vomiting, weight loss or erythema nodosum (a condition causing red-purple swellings on the shins, thighs and less commonly, the arms, joint and muscle pains and fever).

5. What should I know while using NEVIRAPINE VIATRIS?

Things you should do

  • Contact your doctor if you experience a rash on any part of the body.
  • Contact your doctor immediately if the rash is accompanied by other symptoms such as fever, blisters, mouth sores, conjunctivitis, facial swelling, muscle or joint aches, swollen lymph glands, or tiredness.
    These may be symptoms of a hypersensitivity reaction that requires urgent medical attention.
  • Contact your doctor if you experience any symptoms of liver problems, such as loss of appetite, nausea, vomiting, jaundice (yellowing of the skin and/or eyes), dark coloured urine, pale coloured stools, pain/ache or sensitivity to touch in your right abdominal area (below your ribs).
    These could be signs of serious liver dysfunction which your doctor will need to monitor closely and may require stopping treatment with NEVIRAPINE VIATRIS.
  • Keep all of your doctor’s appointments so that your progress can be checked.
    Liver function tests should be performed at regular intervals, especially during the first 18 weeks of treatment with NEVIRAPINE VIATRIS. If the results are abnormal, your doctor will consider either performing more frequent liver function tests (in less severe cases) or stopping treatment with NEVIRAPINE VIATRIS altogether (in more severe cases).
    Women and patients with higher CD4 cell counts seem to be at increased risk for developing liver problems while taking NEVIRAPINE VIATRIS.
    In rare instances, temporary weakness or pain of muscles has been seen in NEVIRAPINE VIATRIS patients experiencing skin and/or liver problems.
  • If you have had a previous opportunistic infection, and you notice symptoms of inflammation occurring when you first start taking NEVIRAPINE VIATRIS, tell your doctor immediately.
    Symptoms of inflammation include redness, swelling, heat and pain. These symptoms have been reported in some patients who have previously had an infection when combination antiretroviral therapy was started.
  • If you are taking oral contraceptives (to prevent pregnancy), you should use additional or different type of contraception.
    NEVIRAPINE VIATRIS may reduce effectiveness of oral contraceptives.
  • If you become pregnant while taking NEVIRAPINE VIATRIS, tell your doctor immediately.
  • If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking NEVIRAPINE VIATRIS.

  • Do not give your medicine to anyone else, even if they have the same condition as you.
  • Do not stop taking your medicine or change the dosage without first checking with your doctor.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how NEVIRAPINE VIATRIS affects you.

This medicine may cause sleepiness or drowsiness in some people. If you have these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

Looking after your medicine

Keep your tablets in the bottle until it is time to take them.

If you take the tablets out of the bottle they may not keep well.

Store it away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine
