Niacinamide
別名: Vitamin B3, Vitamin PP, Niacinamide
- **Give exactly as directed:** This medication is usually given alongside an antibiotic (like tetracycline or doxycycline) to treat immune-mediated skin conditions. - **Be patient:** It often takes **6 to 8 weeks** (sometimes up to 2 months) to see noticeable improvement in your dog's skin. - **Watch for side effects:** Contact your veterinarian if your dog experiences vomiting, loss of appetite, or unusual tiredness. - **Do not substitute:** Ensure you are using *niacinamide* (or nicotinamide) and NOT *niacin* (nicotinic acid), as niacin can cause uncomfortable flushing and other side effects. - Do not stop the medication abruptly once the skin looks better; your veterinarian will likely provide a tapering schedule.
