What is nevirapine?

•

Nevirapine tablets and nevirapine oral solution are prescription HIV medicines used with other HIV medicines to treat HIV (Human Immunodeficiency Virus). HIV is the virus that causes AIDS (Acquired Immune Deficiency Syndrome).

•

Nevirapine extended-release tablets are a prescription medicine used with other HIV medicines to treat HIV (Human Immunodeficiency Virus) in adults and in children who are 6 years of age to less than 18 years of age.

•

Nevirapine and nevirapine extended-release are a type of HIV medicine called a non-nucleoside reverse transcriptase inhibitor (NNRTI).

Nevirapine extended-release tablets are not for use in children less than 6 years of age.

When used with other HIV medicines, nevirapine may:

1.

Reduce the amount of HIV in your blood (called “viral load”).

2.

Help increase the number of CD4 (T) cells in your blood which help fight off other infections.

Reducing the amount of HIV and increasing the CD4 (T) cell count may improve your immune system. This may reduce your risk of death or infections that can happen when your immune system is weak (opportunistic infections).

Nevirapinedoes not cure HIV infection or AIDS.
Nevirapine does not cure HIV or AIDS and you may continue to experience illnesses associated with HIV-1 infection, including opportunistic infections. You should remain under the care of a doctor when using nevirapine.

You must stay on continuous HIV therapy to control HIV infection and decrease HIV-related illnesses.
Avoid doing things that can spread HIV-1 infection to others:

 

•

Do not share needles or other injection equipment.

•

Do not share personal items that can have blood or body fluids on them, like toothbrushes and razor blades.

•

Do not have any kind of sex without protection. Always practice safe sex by using a latex or polyurethane condom to lower the chance of sexual contact with semen, vaginal secretions, or blood.

Ask your doctor if you have any questions on how to prevent passing HIV to other people.

Who should not take nevirapine?

 

Tell your doctor if you have or have had liver problems. Your doctor may tell you not to take nevirapine if you have certain liver problems.

Nevirapine is only for people diagnosed with HIV. If you have not been diagnosed as HIV positive, then do not take nevirapine.
