Read the entire leaflet carefully before starting to take this medication,as it contains important information for you.
Contents of the leaflet
Nevirapine belongs to a group of medications called antiretrovirals, which are used to treat Human Immunodeficiency Virus (HIV) infection.
The active ingredient of this medication is called nevirapine. Nevirapine belongs to a class of anti-HIV medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). Reverse transcriptase is an enzyme that HIV needs to multiply. Nevirapine prevents the action of reverse transcriptase. By blocking the action of reverse transcriptase, Nevirapine helps control HIV-1 infection.
Nevirapine is indicated for the treatment of adults, adolescents, and children aged three years or older who can swallow tablets, infected with HIV-1. You should take Nevirapine with other antiretroviral medications. Your doctor will indicate the appropriate medications for you.
Nevirapine prolonged-release tablets should only be used after a two-week treatment with another type of medication containing nevirapine (suspension or immediate-release tablets), unless you are currently being treated with Nevirapine and are switching to the prolonged-release form.

Warnings and precautions
Consult your doctor or pharmacist before starting to take Nevirapine Teva 400 mg.
During the first 18 weeks of treatment with nevirapine, it is very important that you and your doctor monitor the appearance of liver or skin reactions. These reactions can be severe and even life-threatening. The risk of experiencing these reactions is higher during the first 6 weeks of treatment.
If you experience a severe rash or hypersensitivity (allergic reactions that can appear as a rash) along with other side effects such as:
YOU MUST STOP TAKING NEVIRAPINE AND CONTACT your doctor IMMEDIATELY, as these reactions can be life-threatening or cause death. If you experience only mild rash symptoms without any other reaction, inform your doctor immediately, who will indicate whether you should stop taking nevirapine. If you experience symptoms suggesting liver damage, such as:
you must stop taking nevirapine and contact your doctor immediately. If you experience severe liver, skin, or hypersensitivity reactions while taking nevirapine, DO NOT TAKE NEVIRAPINE AGAIN without first consulting your doctor. You must take your nevirapine dose as indicated by your doctor. This is especially important during the first 14 days of treatment (see more information in "How to take Nevirapine Teva 400 mg"). |
The following patients are at higher risk of developing liver problems:
(women with more than 250 cells/mm³, men with more than 400 cells/mm³)
higher at the start of treatment with nevirapine (women with more than 250 cells/mm³, men with more than 400 cells/mm³)
In some patients with advanced HIV infection (AIDS) and a history of opportunistic infections (AIDS-defining illnesses), signs and symptoms of inflammation of previous infectionsmay appearshortly after starting anti-HIV treatment. These symptoms are believed to be due to an improvement in the body's immune response, allowing it to fight off infections that were present without apparent symptoms. If you notice any symptoms of infection, please inform your doctor immediately.
In addition to opportunistic infections, autoimmune disorders(a condition that occurs when the immune system attacks healthy body tissue) may also appear after you start taking medications for the treatment of your HIV infection. Autoimmune disorders can appear many months after starting treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness starting in the hands and feet and moving up towards the trunk of the body, palpitations, tremors, or hyperactivity, inform your doctor immediatelyto receive the necessary treatment.
Changes in body fat may occur in patients receiving combined antiretroviral therapy. Consult your doctor if you notice changes in body fat (see section 4. "Possible side effects").
In some patients receiving combined antiretroviral therapy, a bone disease called osteonecrosis(death of bone tissue caused by loss of blood supply to the bone) may develop. The duration of combined antiretroviral therapy, the use of corticosteroids, alcohol consumption, severe immune system weakness, and high body mass index may be some of the many risk factors for developing this disease. The symptoms of osteonecrosis are: joint stiffness, pain, and discomfort, especially in the hip, knee, and shoulder, and difficulty moving. If you notice any of these symptoms, inform your doctor.
If you are taking nevirapine and zidovudine together, inform your doctor because you may need to have your white blood cell count checked.
Do nottake Nevirapine after exposure to HIV unless you have been diagnosed with HIV and your doctor has indicated that you should.
Prednisone should not be used to treat rashes associated with Nevirapine.
If you are taking oral contraceptives(e.g., "the pill") or other hormonal methods of birth control while being treated with Nevirapine, you should also use a barrier contraceptive method (e.g., condoms) to prevent pregnancy and HIV transmission.
If you are receiving post-menopausal hormone therapy, consult your doctor before taking this medication.
If you are taking or are prescribed rifampicin to treat tuberculosis, inform your doctor before taking this medication with nevirapine.
The prolonged-release tablets of nevirapine or parts of the tablets may be eliminated and seen occasionally in the feces. These may appear to be whole tablets, but they have not been shown to affect the efficacy of nevirapine.
Children and adolescents
Nevirapine Teva 400 mg prolonged-release tablets may be used in children if:
For younger children, a liquid suspension is available.

It has been shown that the 14-day initial period reduces the risk of experiencing a skin rash.
Patients who are already being treated with immediate-release tablets or oral suspension may be switched to prolonged-release tablets without an initial period.
Since Nevirapine must always be taken in combination with other antiretroviral medications, you must follow the instructions of your other medications carefully. These are provided in the leaflets of these medications.

You must continue taking nevirapine as long as your doctor indicates.
As explained earlier in the 'Warnings and precautions' section, your doctor will monitor you with liver tests and watch for the appearance of side effects such as rash. Depending on the results, your doctor may decide to discontinue or suspend nevirapine treatment. Similarly, your doctor may decide to restart treatment at a lower dose.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.
During HIV treatment, there may be an increase in body weight and glucose and lipid levels in the blood. This may be partly related to the recovery of health and lifestyle, and in the case of increased blood lipids, it may sometimes be due to HIV medications themselves. Your doctor will monitor these changes.
Like all medications, this medication can produce adverse effects, although not all people suffer from them.
As already mentioned in 'Warnings and Precautions', the most important adverse effects of nevirapine are severe skin reactions and life-threatening liver damage. These reactions occur mainly during the first 18 weeks of nevirapine treatment. This is, therefore, an important period that requires close monitoring by your doctor.
If you notice any symptoms of a rash, inform your doctor immediately.
When a rash occurs, it is usually mild to moderate. However, in some patients, a rash appears in the form of a blistering skin reaction that can be severe or life-threatening (Stevens-Johnson syndrome and toxic epidermal necrolysis), and there have been reported fatalities. Most cases of rash, both severe and mild/moderate, occur during the first six weeks of treatment.
If a rash appears and you also feel unwell, you must stop treatment and see your doctor immediately.
Hypersensitivity reactions (allergies) can occur. Such reactions can appear as anaphylaxis (a severe allergic reaction) with symptoms such as:
Hypersensitivity reactions can also present as a rash with other adverse effects such as:
If you experience a rash and any of the other adverse effects of a hypersensitivity reaction (allergy), inform your doctor immediately. These reactions can be fatal.
Abnormalities in liver function have been described with the use of Nevirapine. This includes some cases of liver inflammation (hepatitis), which can be sudden and severe (fulminant hepatitis) and liver failure, both of which can be fatal.
Inform your doctor if you experience any of the following clinical symptoms of liver damage:
The following adverse effects have been reported in patients who received nevirapine 200 mg tablets during the initial 14-day phase:
Frequent (may affect up to 1 in 10 people):
Uncommon (may affect up to 1 in 100 people):
drug reaction with systemic symptoms (drug reaction with eosinophilia and systemic symptoms)
yellowing of the skin (jaundice)
Rare (may affect up to 1 in 1,000 people):
The following adverse effects have been reported in patients who received nevirapine prolonged-release tablets once daily in the maintenance phase:
Frequent (may affect up to 1 in 10 people):
Uncommon (may affect up to 1 in 100 people):
drug reaction with systemic symptoms (drug reaction with eosinophilia and systemic symptoms)
decrease in red blood cell count (anemia)
When nevirapine has been used in combination with other antiretroviral medications, the following events have also been reported:
These effects are generally associated with other antiretroviral agents and may occur when nevirapine is used in combination with other agents; however, it is unlikely that these effects are due to treatment with nevirapine.
Other Adverse Effects in Children and Adolescents
A decrease in white blood cell count (granulocytopenia) may occur, more frequently in children. A decrease in red blood cell count (anemia), which may be related to treatment with nevirapine, is also more frequent in children. As with symptoms of rash, inform your doctor of any adverse effect.
