TENOLAM E TABLET

Q1: What is Tenolam-E (Tenofovir/Lamivudine/Efavirenz) used for?

Tenolam-E is a single-tablet triple-combination of Tenofovir DF 300mg + Lamivudine 300mg + Efavirenz 600mg for once-daily HIV-1 treatment. This WHO-recommended regimen is widely used globally, particularly in resource-limited settings, due to its efficacy, cost-effectiveness, and single-pill convenience.

Q2: How do all three components work together?

Tenofovir and Lamivudine (dual NRTIs) inhibit HIV reverse transcriptase through chain termination at different positions. Efavirenz (NNRTI) binds directly to reverse transcriptase at an allosteric site, providing triple-mechanism synergistic suppression.

Q3: Why must Tenolam-E be taken at night on an empty stomach?

Efavirenz's CNS side effects (dizziness, vivid dreams, difficulty concentrating) are experienced by ~50% of patients. Evening/bedtime dosing allows sleep to minimize daytime impact. High-fat meals increase Efavirenz absorption and worsen CNS effects — take on a near-empty stomach.

Q4: How long do Efavirenz CNS side effects last?

CNS effects typically begin in the first 1–2 weeks and resolve in most patients within 4–6 weeks. If severe depression, suicidal thoughts, or psychosis develop, seek immediate medical evaluation.

Q5: What are the most common side effects?

CNS effects (dizziness, vivid dreams), rash (usually mild, first 2 weeks), nausea, diarrhea, and fatigue are most common. Long-term TDF use may reduce bone mineral density and rarely cause kidney toxicity.

Q6: Does the Lamivudine/Tenofovir component also treat hepatitis B?

Yes. Both Tenofovir and Lamivudine suppress HBV. This regimen provides dual HIV/HBV coverage in co-infected patients. Stopping Tenolam-E without maintaining HBV suppression can cause severe hepatitis flares.

Q7: What serious side effects require emergency care?

Stevens-Johnson syndrome (rare, severe blistering rash), severe psychiatric symptoms, lactic acidosis (muscle pain, breathing difficulty), or severe hepatotoxicity require immediate emergency evaluation.

Q8: What drug interactions affect Tenolam-E?

Efavirenz is a CYP3A4 inducer reducing levels of many drugs including hormonal contraceptives, some statins, and other antiretrovirals. Use additional contraception. Rifampicin requires Efavirenz dose increase to 800mg/day. Comprehensive interaction review is essential.

Q9: Can Tenolam-E be used during pregnancy?

Efavirenz has been used throughout pregnancy without confirmed teratogenicity in humans. TDF and Lamivudine are both pregnancy-safe. The complete regimen should be managed jointly by HIV and obstetric specialists.

Q10: What monitoring is required on Tenolam-E?

CD4 and viral load at baseline and every 3–6 months. Renal function (TDF component) every 6 months. Liver function tests. Bone density assessment if risk factors present. Psychiatric symptom monitoring especially in first 6 weeks.

Q11: How should Tenolam-E 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. Tenolam-E requires specialist HIV prescribing with baseline CD4, viral load, and renal function assessment, plus counselling about Efavirenz CNS effects.
