Summary
Sorbitol-containing liquid medicines taken with lamivudine oral solution lower lamivudine exposure in a dose-related way. Reduced exposure may lead to inadequate viral suppression and resistance, especially in children.
What this interaction means in plain words
Lamivudine and Sorbitol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Lamivudine belongs to Anti Virals; Sorbitol belongs to Gastrointestinal Tract.
Why it happens
Sorbitol appears to reduce lamivudine absorption, possibly through osmotic effects on the gut; the mechanism is not fully established.
What to do
Avoid regular co-administration of sorbitol-containing solutions with lamivudine where possible. If unavoidable, monitor viral load closely or use lamivudine tablets or a sorbitol-free formulation.
