Calculate safe OTC medication dosages for dogs and cats based on weight. Includes Benadryl and antihistamine dosing guidelines.
⚠️ Important Disclaimer
This calculator provides general guidelines for OTC medications only. Always consult your veterinarian before giving any medication to your pet. Dosages may vary based on:
- Pet's age, health conditions, and medical history
- Other medications your pet is taking
- Specific medication formulation and strength
- Individual pet sensitivity and metabolism
Never use medications containing decongestants (like pseudoephedrine) as these are toxic to pets. This tool is for informational purposes only and does not replace professional veterinary advice.
How This Tool Works
This calculator provides general dosing guidelines for common OTC medications based on pet weight and species. The calculations use weight-based dosing formulas that are standard in veterinary medicine. Benadryl (diphenhydramine) dosing for dogs is typically 1mg per pound (2.2mg per kg) every 8-12 hours, while cats require more conservative dosing at 0.5-1mg per pound due to their increased sensitivity. The calculator accounts for species differences, as cats metabolize medications differently than dogs and may be more prone to adverse effects.
Always verify with your veterinarian before administering any medication, as individual pets may have health conditions, take other medications, or have sensitivities that affect dosing. This tool is for informational purposes only and does not replace professional veterinary advice. Never use medications containing decongestants (like pseudoephedrine) as these are toxic to pets. The calculator provides a starting point, but your veterinarian can provide personalized recommendations based on your pet's specific health needs.
