Truvada is the brand name of PrEP, a daily pill that’s up to 99% effective at preventing at-risk individuals from contracting HIV when used correctly. PrEP stands for pre-exposure prophylaxis — in other words, protection before being exposed to the virus. The medication contains a combination of emtricitabine (200 mg) and tenofovir disoproxil fumarate (300 mg).
Emtricitabine is an FDA-approved HIV medication that’s always used with other medications. It works by blocking an enzyme to prevent HIV from spreading and might lower the amount of HIV in your body. Specifically – the medication is a nucleoside reverse transcriptase inhibitor (NRTI).
Tenofovir Disoproxil Fumarate
Tenofovir disoproxil fumarate is another FDA-approved NRTI used with other HIV meds. This is why Truvada contains both this medication and emtricitabine. Tenofovir disoproxil fumarate blocks the same enzymes as emtricitabine to the same effect.
Truvada is designed for people who are currently HIV negative. Your Nurx™ healthcare provider will require you to take an HIV test before prescribing Truvada. Every three months on the medication, you must be tested again to renew your prescription. Truvada for PrEP does not prevent other sexually transmitted infections or pregnancy.
