Ricovir EM Tablet

Q1: What is Ricovir EM (Emtricitabine/Tenofovir DF 200/300mg) used for?

Ricovir EM is a dual NRTI combination used as the backbone of HIV combination therapy, also approved for HIV pre-exposure prophylaxis (PrEP). It is equivalent to the branded Truvada and is used worldwide as a foundation for HIV regimens.

Q2: How do Emtricitabine and Tenofovir DF work together?

Both inhibit HIV reverse transcriptase as chain terminators — Emtricitabine (as 5'-triphosphate) and Tenofovir (as tenofovir diphosphate) compete with natural nucleotides. Their complementary mechanisms provide synergistic NRTI activity with a high barrier to resistance.

Q3: What is PrEP and can Ricovir EM be used for it?

Pre-Exposure Prophylaxis (PrEP) uses antiretrovirals in HIV-negative people at high risk of HIV acquisition to prevent infection. Emtricitabine/Tenofovir DF is FDA-approved for PrEP and reduces HIV transmission risk by over 99% when taken correctly.

Q4: How is Ricovir EM taken?

For HIV treatment: one tablet once daily as part of a complete antiretroviral regimen. For PrEP: one tablet once daily at a consistent time. Can be taken with or without food.

Q5: What kidney monitoring is required for Tenofovir DF?

TDF is associated with proximal renal tubular toxicity in some patients. Baseline and regular creatinine, eGFR, phosphate, and urine protein monitoring is required. Patients with eGFR below 30 ml/min should not use TDF — TAF-based alternatives are preferred.

Q6: What are the most common side effects?

Nausea, diarrhea, fatigue, headache, and bone pain are most common. Long-term TDF use can reduce bone mineral density. Renal tubular dysfunction may present as low phosphate or low urine specific gravity.

Q7: Does Ricovir EM treat hepatitis B?

Yes. Both Emtricitabine and Tenofovir DF are active against HBV. This regimen suppresses both HIV and HBV in co-infected patients. Stopping Ricovir EM without maintaining HBV coverage can cause severe HBV flares.

Q8: What drug interactions affect Ricovir EM?

TDF interacts with didanosine (ddI — co-administration contraindicated), HIV drugs that reduce renal clearance, and NSAIDs (nephrotoxicity risk). Emtricitabine has minimal interactions. Always disclose all medications.

Q9: Can Ricovir EM be used during pregnancy?

Emtricitabine/TDF has the most extensive safety data in HIV-positive pregnant women and is a preferred NRTI backbone in many HIV-in-pregnancy guidelines. Discuss the complete regimen with your HIV/OB specialist.

Q10: What monitoring is required during Ricovir EM therapy?

CD4 and viral load at baseline and every 3–6 months. Renal function tests (creatinine, eGFR, phosphate, urine protein) at baseline and every 6 months. Bone density assessment if osteoporosis risk factors are present.

Q11: How should Ricovir EM be stored?

Store at room temperature away from light and moisture. Keep in original packaging out of reach of children.

Q12: Do I need a prescription?

Yes. Ricovir EM requires specialist HIV prescribing for treatment, or physician prescribing for PrEP with baseline HIV testing and ongoing monitoring.
