1. What is Delsym (Dextromethorphan)?

Delsym is an extended-release formulation of dextromethorphan, a cough suppressant sometimes used off-label for dogs. It works by suppressing the cough reflex in the brain.

2. How Does the Calculator Work?

The calculator uses the standard veterinary dosage formula:

Where:

• \( W \) — Dog's weight in kilograms
• 0.5 to 1 — Dosage range in mg per kg of body weight

Explanation: The dosage is calculated based on the dog's weight, with the standard range being 0.5-1 mg per kg of body weight every 12 hours.

3. Importance of Proper Dosing

Details: Accurate dosing is crucial as dextromethorphan can cause side effects like sedation, gastrointestinal upset, or (in rare cases) serotonin syndrome if overdosed.

4. Using the Calculator

Tips: Enter your dog's weight in kilograms. For best results, weigh your dog rather than estimating. Always consult your veterinarian before administering any medication.
