What is Complera Medication Used For? Side Effects and Dosage

What is Complera?

Complera is a fixed-dose antiretroviral drug that contains three drugs: tenofovir, emtricitabine, and rilpivirine. Complera uses a co-formulation that contains drugs of different classes, as rilpivirine, brand name Edurant, is a non-nucleoside reverse transcriptase inhibitor, emtricitabine, brand name Emtriva, is a nucleoside analogue (‘nuke’), and tenofovir, brand name Viread, is a nucleotide analogue. The drug is manufactured by Gilead Sciences.

What is This Medication Used For?

Complera medication is used to treat, not cure, HIV. It is indicated for combination therapy for people with HIV who have no prior experience with anti-HIV drugs or those who have HIV and have not developed a resistance to any of the three drugs in Complera (emtricitabine /rilpivirine/ tenofovir).

The drug is used to interfere with the activity of the enzyme reverse transcriptase (RT). Reverse transcriptase is used by HIV-infected cells to create copies of the virus, so when the enzyme is inhibited, the production and spread of HIV is slowed down.

How to Take It

Complera HIV drug comes in a purplish-pink tablet that must be taken daily with a meal. However, grapefruits and grapefruit juice should be avoided, as they increase the concentration of rilpivirine which could lead to side effects.
