Tinidazole is a single-dose treatment for giardiasis with superior cure rates (>90%) compared to metronidazole, recommended by WHO for first-line use.
Tinidazole has the same nitroimidazole mechanism as metronidazole but achieves higher tissue concentrations and a longer half-life (12–14 hours), allowing effective single-dose treatment.
Adults: 2 g as a single dose. Children: 50 mg/kg as a single dose (max 2 g). Take with food. A single dose improves adherence significantly.
This is a general reference. Always follow your physician's prescription and current treatment guidelines.
Studies show tinidazole achieves cure rates of 90–100% with a single dose versus 80–95% with a 5-7 day metronidazole course. Single-dose convenience also improves adherence.
Yes. Tinidazole at 50 mg/kg as a single dose is safe and effective for children over 3 years of age. The tablets can be crushed and mixed with cherry syrup for younger children.
Retreatment options include a second tinidazole dose, a metronidazole 7-day course, or albendazole as an alternative. Nitazoxanide is used in resistant cases.
