Lamivudine + Zidovudine + Nevirapine is a fixed-dose combination (FDC) antiretroviral tablet combining two nucleoside reverse transcriptase inhibitors (NRTIs) with one non-nucleoside reverse transcriptase inhibitor (NNRTI) in a single tablet, intended to simplify triple-drug antiretroviral therapy (ART).
| Step | Regimen |
|---|---|
| Lead-in period (first 14 days) | Nevirapine alone 200 mg once daily (using a separate nevirapine-only tablet), to reduce the risk of rash. Lamivudine + Zidovudine + Nevirapine fixed-dose tablets are not used during this lead-in period. |
| Maintenance (from day 15, if no rash/hepatotoxicity) | One Lamivudine + Zidovudine + Nevirapine tablet (typically lamivudine 150 mg + zidovudine 300 mg + nevirapine 200 mg) taken twice daily, approximately every 12 hours. |
Patients already established and tolerating nevirapine do not require a repeat lead-in when switching to Lamivudine + Zidovudine + Nevirapine. If a nevirapine dose is missed for more than 7 days, the lead-in dosing should generally be restarted under medical supervision.
Pediatric dosing of Lamivudine + Zidovudine + Nevirapine is weight-band based, using pediatric-strength scored or dispersible tablets of the same three-drug combination, following current WHO/national pediatric ART dosing charts. The adult-strength tablet must not be split or estimated for children; a formulation matched to the child's weight band must be used. See Pediatric Use.
Lamivudine and zidovudine both require dose reduction in renal impairment (creatinine clearance below 50 mL/min), but their doses cannot be adjusted independently within a fixed-dose tablet. Patients with significant renal impairment should generally not use the Lamivudine + Zidovudine + Nevirapine fixed-dose tablet and should instead receive the three components as separate, individually dosed medicines under physician supervision.
Lamivudine + Zidovudine + Nevirapine is contraindicated in moderate-to-severe hepatic impairment (see Contraindications). Mild hepatic impairment requires close clinical and laboratory monitoring.
If a dose of Lamivudine + Zidovudine + Nevirapine is missed, it should be taken as soon as remembered unless it is almost time for the next dose, in which case the missed dose should be skipped — never take a double dose. Consistent, on-time dosing is essential (see Precautions and Warnings).
Side effects of Lamivudine + Zidovudine + Nevirapine reflect the combined profile of its three components.
| Category | Effects |
|---|---|
| Very common/common | Nausea, headache, fatigue, diarrhea, abdominal discomfort, and rash (usually mild-to-moderate) |
| Hematologic (zidovudine) | Anemia, neutropenia; rarely severe bone marrow suppression requiring transfusion or dose interruption |
| Hepatic (nevirapine) | Elevated liver enzymes; rarely severe, potentially fatal hepatotoxicity (see Precautions and Warnings) |
| Dermatologic (nevirapine) | Rash, and rarely severe skin reactions including Stevens-Johnson syndrome and toxic epidermal necrolysis (see Precautions and Warnings) |
| Metabolic/muscular | Lactic acidosis, hepatomegaly with steatosis (rare, NRTI class effect), lipodystrophy, and (with long-term zidovudine use) myopathy |
Patients should seek prompt medical attention for new rash, yellowing of the skin/eyes, unusual tiredness, easy bruising/bleeding, or signs of severe allergic reaction.
