Viramune Precautions

Viramune can cause serious side effects. These include severe liver and skin problems that can cause death. These problems can happen at any time during treatment, but your risk is highest during the first 18 weeks of treatment.

  • Women with CD4+ counts higher than 250 cells/mm3. This group has the highest risk.
  • Men with CD4+ counts higher than 400 cells/mm3.

1.  Severe liver problems: Anyone who takes Viramune may get severe liver problems. In some cases these liver problems can lead to liver failure and the need for a liver transplant, or death. People who have a higher CD4+ cell count when they begin Viramune treatment have a higher risk of liver problems, especially:

If you are a woman with CD4+ counts higher than 250 cells/mm3 or a man with CD4+ counts higher than 400 cells/mm3, you and your doctor will decide whether starting Viramune is right for you.
In general, women have a higher risk of liver problems compared to men.
People who have abnormal liver test results before starting Viramune treatment and people with hepatitis B or C also have a greater chance of getting liver problems.
You may get a rash if you have liver problems.
Stop taking Viramune and call your doctor right away if you have any of the following symptoms of liver problems:
  • dark (tea colored) urine
  • yellowing of your skin or whites of your eyes
  • light-colored bowel movements (stools)
  • fever
  • feel unwell or like you have the flu
  • nausea (feeling sick to your stomach)
  • pain or tenderness on your right side below your ribs
  • tiredness
  • loss of appetite
Your doctor should see you and do blood tests often to check your liver function during the first 18 weeks of treatment with Viramune. You should continue to have your liver checked regularly during your treatment with Viramune. It is important for you to keep all of your doctor appointments.
2.  Severe rash and skin reactions: Skin rash is the most common side effect of Viramune. Most rashes happen in the first 6 weeks of taking Viramune. Rashes and skin reactions may be severe, life-threatening, and in some people, may lead to death. Stop using Viramune and call your doctor right away if you get a rash with any of the following symptoms:
  • blisters
  • mouth sores
  • red or inflamed eyes, like "pink eye" (conjunctivitis)
  • liver problems (see symptoms of liver problems above)
  • swelling of your face
  • feel unwell or like you have the flu
  • fever
  • tiredness
  • muscle or joint aches
If your doctor tells you to stop treatment with Viramune because you have had any of the serious liver or skin problems described above, you should never take Viramune again.
Tell your doctor if you have or have had liver problems. Your doctor may tell you not to take Viramune if you have certain liver problems. Viramune is only for people diagnosed with HIV. If you have not been diagnosed as HIV positive, then do not take Viramune.

Viramune Usage

Viramune is always taken in combination with other anti-HIV medications.

  • Take Viramune exactly as your doctor tells you to take it. Do not change your dose unless your doctor tells you to.
  • You should never take more than one form of Viramune at the same time. Talk to your doctor if you have any questions.
  • You may take Viramune with or without food.
  • Do not miss a dose of Viramune, because this could make HIV harder to treat. If you miss a dose of Viramune, take the missed dose as soon as you remember. If it is almost time for your next dose, do not take the missed dose, just take the next dose at your regular time. Do not take two doses at the same time.
  • If you stop taking Viramune for more than 7 days, ask your doctor how much to take before you start taking it again. You may need to begin taking the Viramune starting dose again, which is taken 1 time each day for 14 days.

Starting Viramune tablets:

  1. Your doctor should start you with 1 dose each day to lower your chance of getting a serious rash. It is important that you only take 1 dose of Viramune each day for the first 14 days.
    • Call your doctor right away if you get a skin rash during the first 14 days of Viramune treatment and do not increase your dose to 2 times a day.
    • You should never take your starting dose for longer than 28 days. If after 28 days you are still receiving this starting dose because you have a rash, you and your doctor should talk about prescribing another HIV medicine for you instead of Viramune.
    • Do not increase your dose to 2 times a day if you have a rash.
       
  2. Day 15, you will take 1 Viramune tablet two times a day.

If you or your child takes Viramune suspension (liquid), shake it gently before each use. Use an oral dosing syringe or dosing cup to measure the right dose. The oral dosing syringe and dosing cup are not provided with Viramune suspension. Ask your pharmacist for a syringe or cup if you do not have one.

  • After drinking the medicine, fill the dosing cup with water and drink it to make sure you get all the medicine.
  • If the dose is less than 1 teaspoon (5 mL), use the syringe instead of the dosing cup.

Viramune FDA Warning

WARNING: LIFE-THREATENING (INCLUDING FATAL) HEPATOTOXICITY and SKIN REACTIONS

HEPATOTOXICITY:

Severe, life-threatening, and in some cases fatal hepatotoxicity, particularly in the first 18 weeks, has been reported in patients treated with nevirapine. In some cases, patients presented with non-specific prodromal signs or symptoms of hepatitis and progressed to hepatic failure. These events are often associated with rash. Female gender and higher CD4+ cell counts at initiation of therapy place patients at increased risk; women with CD4+ cell counts greater than 250 cells/mm3, including pregnant women receiving Viramune in combination with other antiretrovirals for the treatment of HIV-1 infection, are at the greatest risk. However, hepatotoxicity associated with Viramune use can occur in both genders, all CD4+ cell counts and at any time during treatment. Hepatic failure has also been reported in patients without HIV taking Viramune for post-exposure prophylaxis (PEP). Use of Viramune for occupational and non-occupational PEP is contraindicated. Patients with signs or symptoms of hepatitis, or with increased transaminases combined with rash or other systemic symptoms, must discontinue Viramune and seek medical evaluation immediately.

SKIN REACTIONS:

Severe, life-threatening skin reactions, including fatal cases, have occurred in patients treated with Viramune. These have included cases of Stevens-Johnson syndrome, toxic epidermal necrolysis, and hypersensitivity reactions characterized by rash, constitutional findings, and organ dysfunction. Patients developing signs or symptoms of severe skin reactions or hypersensitivity reactions must discontinue Viramune and seek medical evaluation immediately. Transaminase levels should be checked immediately for all patients who develop a rash in the first 18 weeks of treatment. The 14-day lead-in period with Viramune 200 mg daily dosing has been observed to decrease the incidence of rash and must be followed.

MONITORING:

Patients must be monitored intensively during the first 18 weeks of therapy with Viramune to detect potentially life-threatening hepatotoxicity or skin reactions. Extra vigilance is warranted during the first 6 weeks of therapy, which is the period of greatest risk of these events. Do not restart Viramune following clinical hepatitis, or transaminase elevations combined with rash or other systemic symptoms, or following severe skin rash or hypersensitivity reactions. In some cases, hepatic injury has progressed despite discontinuation of treatment.
