Kivexa

What is Kivexa for?

Abacavir and Lamivudine combination known as Kivexa®are both antiretroviral medications used for treating human immunodeficiency virus (HIV) infection. It works by preventing the virus from reproducing, and hence, reducing the amount of virus in your body. This increases the CD4 cell count in your body. CD4 cells are a type of immune cells that help your body fight off infections.

KIvexa® is not a cure for HIV infection. It must be taken on a daily basis to slow the progression of the disease.

How should I take or use Kivexa?

This medication can be taken with or without food.  Swallow the tablet whole, do not crush or chew it. Do not stop taking your medication without consulting your healthcare professional. Do not miss any doses in order to fully control the virus and prevent it from damaging your health. 

What should I do if I forget to take or use Kivexa?

If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Then take your next dose at the usual time. Do not take two doses to make up for the missed dose.

The symptoms of a drug allergy include one or more of the following:

Abacavir can cause a serious allergy reaction known as Abacavir-associated hypersensitivity reaction. This is characterised by:

• Fever
• Rash
• Gastrointestinal symptoms (including nausea, vomiting, diarrhoea, or stomach pain)
• Flu-like symptoms
• Extreme tiredness or achiness
• Shortness of breath
• Cough
• Sore throat

It can occur any time during the treatment with Abacavir but is more likely during the first 6 weeks of starting treatment. If you experience any of these symptoms, you should stop your medication and see your healthcare professional immediately. You are more likely to develop a hypersensitivity reaction to Abacavir if you have the HLA-B*5701 gene.
