Trimeprazine with Prednisolone
Also known as: Temaril-P, Vanectyl-P
- **Increased Thirst and Urination**: Your dog will likely drink more water and need to urinate more frequently. Ensure they have constant access to fresh water and provide extra bathroom breaks. - **Increased Appetite**: This medication can make your dog very hungry. Stick to their normal feeding schedule to prevent unwanted weight gain. - **Sedation**: You may notice mild drowsiness or lethargy, especially during the first few days of treatment. This is normal but contact your vet if it seems severe. - **Do Not Stop Abruptly**: If your dog has been on this medication for more than a few weeks, the dose must be tapered slowly under veterinary guidance. Stopping suddenly can cause a life-threatening hormonal imbalance. - **Monitor for Infections**: Because this drug suppresses the immune system, contact your veterinarian if you notice signs of infection, worsening skin lesions, or severe lethargy.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

Drug interactions
- ACE Inhibitors: Phenothiazines may increase hypotensive effects
- Amphotericin B: Concomitant use with glucocorticoids may cause severe hypokalemia
- Antacids: May cause reduced GI absorption of oral phenothiazines
- Antidiarrheal mixtures (Kaolin/pectin, bismuth): May cause reduced GI absorption of oral phenothiazines
- Anticholinesterase agents (pyridostigmine, neostigmine): In myasthenia gravis patients, concomitant use may lead to profound muscle weakness
- Aspirin (salicylates): Glucocorticoids may reduce salicylate blood levels
- Cisapride: Increased risk for cardiac arrhythmias when used with phenothiazines
- CNS Depressants (barbiturates, narcotics, anesthetics): May cause additive CNS depression
