What is Cimduo?
Cimduo is a combination drug of lamivudine and tenofovir. Tenofovir and Lamivudine are antiviral medications that prevent HIV (human immunodeficiency viruses) from multiplying in the body. Cimduo can be used to treat HIV. HIV is the virus responsible for acquired immune deficiency syndrome. Cimduo does not cure HIV or AIDS. Cimduo can be used on adults and children weighing at least 77 lbs.
Warnings
Cimduo may cause serious side effects. If you experience symptoms like upper stomach pains, loss of appetite or dark urine, yellowing skin or eyes, or bone pains, call your doctor immediately. You could develop lactic acidosis. This is a dangerous buildup of lactic acid in your blood. If you experience unusual muscle pains, difficulty breathing, stomach pains, nausea, or feel cold or very tired, call your doctor. Cimduo may cause your hepatitis C to become active or worsen if you have ever had it. You may require frequent liver function testing for several months.
Before you take this drug
Cimduo should not be used if you have an allergy to lamivudine and tenofovir.
Inform your physician of any of the following issues:
- Liver disease, including cirrhosis, hepatitis B, and C (especially if also using ribavirin or interferon beta);
- Kidney disease (or dialysis if you have it);
- A pancreas disorder;
- Bone problems include osteoporosis and broken bones.
You can develop lactic acidosis. This is a dangerous accumulation of lactic acids in your blood. It may be more common if there are other medical conditions or if you have taken HIV medication for a long time. Consult a medical provider in order to assess your personal risk factors. Use your medication properly to control infections. HIV can be transmitted to your child if you do not control the virus during pregnancy. You may have your name listed in a registry that tracks the effects of antiviral medicines on the baby. Breastfeeding is not recommended for women with HIV/AIDS. Even if the baby was born HIV-free, the virus can be transmitted to the infant through your breast milk.
