How to take Viramune
This medicine is used to treat HIV infection (the virus that causes AIDS). It is used in grouping with other anti-HIV medicines in selected patients. No medicine can survive HIV infection, and your illness (infection, etc.) can last. Because HIV can quickly become resistant to this medicine, when used alone, viramune should be used with at least 1 other anti-HIV medicine.
It should be taken orally as recommended. The usual dose is one 200 mg tablet daily for the first 14 days followed by one 200 mg tablet twice daily. Viramune is used in combination with at least one other anti-retroviral anti-HIV medicine. It is necessary to strictly follow the dosage instructions to minimize serious side effects, such as rashes. If the rash develops within the first two weeks, the viramune dose is not increased until the rash disappears. If treatment is blocked for more than 7 days, you should start treatment again as prescribed by your doctor, usually one 200 mg tablet daily for 14 days, followed by one 200 mg tablet twice daily. Read the patient leaflet available from the pharmacy.
Drug class and mechanism
Viramune is an oral medicine used to treat human immunodeficiency virus (HIV) infection. It is like efavirenz (Sustiva) and delavirdine (Rescriptor). Viramune belongs to a class of medicines called reverse transcriptase inhibitors, which include zalcitabine (Hivid), zidovudine (Retrovir), didanosine (Videx) and lamivudine (Epivir). During HIV infection, the HIV virus grows in your body’s cells. The newly created viruses are then unlimited from cells and spread throughout the body, where they infect other cells. In this method, the infection spreads to new, uninfected cells that the body constantly produces and HIV infection continues. When creating new viruses, HIV must produce new DNA for each virus. Invalid transcriptase is the enzyme that the virus uses to create this new DNA. Viramune openly inhibits reverse transcriptase activity and blocks the production of DNA and new viruses. Unlike zidovudine, nevirapine does not need to be converted to its active form and does not compete with the compound (thymidine triphosphate), which is required by the HIV virus to produce new DNA. Viramune does not kill existing HIV and is not a cure for HIV.
If you miss a dose, take it as soon as you remember. If 2 hours elapse from the next dose, skip the missed dose and resume the usual dosing schedule. It is important not to miss doses of this medicine.
Store the medicine at room temperature between 59 and 86 degrees F (15 to 30 degrees C) away from moisture and light as directed. Do not store in the bathroom. Store in a tightly closed bottle.
