Zonisamide oral suspension?

Zonisamide is not sold as an oral suspension in the US (and in many markets). It’s available as capsules (e.g., 25 mg, 50 mg, 100 mg) and tablets. If a liquid form is needed, a pharmacist may prepare an extemporaneous (compounded) suspension from the capsules, but that is not an FDA-approved product and its strength, stability, and labeling can vary.

If you have a compounded suspension or are considering one, I can help with calculations if you know:
- the suspension’s strength (mg per mL)
- the prescribed dose (mg per administration and frequency)

Common dosing notes (talk to your clinician for your exact plan):
- Adults (adjunctive therapy): typical starting dose around 100 mg/day, titrating up to about 400–600 mg/day in 1–2 divided doses (max ~600 mg/day).
- Children: often dosed by weight, roughly 1–8 mg/kg/day in 1–2 divided doses (maximums vary; many guidelines cite up to ~500 mg/day).

Important safety points:
- Zonisamide is a sulfonamide derivative; monitor for rash, metabolic acidosis, kidney stones, or signs of hypersensitivity.
- Can cause drowsiness, dizziness; avoid operating heavy machinery until you know how it affects you.
- Dose adjustments may be needed in kidney impairment; avoid changes without medical advice.
- Pregnancy and breastfeeding require medical advice; discuss with your clinician.

If you can share the exact strength of the suspension (mg/mL) and the prescribed dose, I’ll help you calculate the mL dose needed. If you’re unsure, contact the pharmacy that prepared the suspension or your prescriber for the correct liquid formulation and dosing.
