What LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 is used for
LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 contains lamivudine and zidovudine which belong to a group of medicines called antiretrovirals.
Please note that lamivudine is available as a stand alone tablet (as LAMIVUDINE VIATRIS 150/300 lamivudine 150mg & 300mg tablets).
Lamivudine with zidovudine is used alone or with other antiretrovirals, to slow down the progression of human immunodeficiency virus (HIV) infection, which can lead to Acquired Immune Deficiency Syndrome (AIDS) and other related illnesses (e.g. AIDS-related Complex or ARC).
Lamivudine with zidovudine does not cure AIDS or HIV infection, but slows production of human immunodeficiency virus. In this way it stops ongoing damage to the body’s immune system, which fights infection.
Lamivudine with zidovudine does not reduce the risk of passing HIV infection to others. You can still pass on the HIV virus when taking this medicine, although the risk is lowered by effective antiretroviral therapy. Discuss with your doctor the precautions needed to avoid infecting other people.
While taking LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 and/or any other therapy for HIV disease, you may continue to develop other infections and other complications of HIV infection. You should keep in regular contact with the doctor. The long-term risks and benefits of taking lamivudine / zidovudine combination tablets are not known.
Your doctor may have prescribed LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 for another reason. Ask your doctor if you have any questions about why it has been prescribed for you.
LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 is not addictive.

Like all medicines, LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 can cause some side effects. If they occur, they are most likely to be minor and temporary. However, some may be serious and need medical attention.

While you are taking LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300, it is very important that your doctor keeps a close check on your health and takes blood samples to monitor levels of red and white blood cells. If you develop anaemia or neutropenia, your doctor may reduce or stop the dose of LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300, or recommend standard treatment for these conditions. Ask your doctor any questions which you may have.

Within the first few weeks of treatment with anti-HIV medicines, some people, particularly those that have been HIV positive for some time, may develop inflammatory reactions (e.g., pain, redness, swelling, high temperature) which may resemble an infection and may be severe. It is thought that these reactions are caused by a recovery in the body’s ability to fight infections, previously suppressed by HIV. If you become concerned about any of the new symptoms, or any changes in your health after starting HIV treatment, please discuss with your doctor immediately.
Ask your doctor or pharmacist to answer any questions you may have. If you experience any of these side effects, and they concern you, see your doctor or pharmacist.

If you are on medication for HIV and become very sick, with fast breathing, stop taking LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 and consult your doctor immediately.

This can be life threatening. This illness occurs more often in women than men.
See your doctor if you feel generally unwell with a loss of appetite, nausea, vomiting, itching, yellowness of the skin or eyes or dark coloured urine, or if the blood tests of your liver function are abnormal. It is likely you will have to stop taking LAMIVUDINE/ZIDOVUDINE VIATRIS 150/300 tablets.
