Brand Name: Epzicom  |
Drug Class: Nucleoside Reverse Transcriptase Inhibitors
|
Epzicom is a combination of two antiretroviral drugs: abacavir sulfate (Ziagen) and lamivudine (Epivir). Both of these medicines are nucleoside reverse transcriptase inhibitors (NRTIs). NRTIs block reverse transcriptase, a protein that HIV needs to make more copies of itself.

HIV/AIDS-Related Uses
|
|
|
|
Abacavir sulfate and lamivudine are approved individually by the FDA for the treatment of HIV infection in adults and children. Because these two medicines are frequently prescribed together, the manufacturer has combined them into one tablet. Epzicom was approved by the FDA on August 2, 2004, for use with other antiretroviral agents in the treatment of HIV infection in adults. Epzicom should be used in combination with other types of anti-HIV drugs.
|
|
|
|
Epzicom does not cure or prevent HIV infection or AIDS and does not reduce the risk of passing the virus to other people.

Possible Side Effects
|
|
|
|
Along with its desired effects, Epzicom can cause some unwanted effects. Epzicom contains abacavir sulfate, which has caused serious allergic reactions, some resulting in death. Severe allergic reactions usually occur during the first 6 weeks of taking the drug but can occur at any time. Individuals should stop taking this medicine and tell a doctor right away if any of the following symptoms occur: sudden fever, skin rash, severe tiredness or achiness, diarrhea, nausea,vomiting, stomach pain, sore throat, shortness of breath, cough, or a general ill feeling. These symptoms are listed on the prescription's warning card, which the patient should carry. If a doctor suspects an allergic reaction, the individual should never take abacavir or an abacavir-containing medicine again. Individuals should tell a doctor if they have any of these side effects.

A doctor should be notified if an individual taking this medication experiences digestive system problems, joint or muscle pain and weakness, pain or tingling of hands or feet, headache, dizziness, or unusual tiredness.
