Expired prednisone can cause several problems. Watch for these symptoms:
| Gastrointestinal upset | Vomiting, diarrhea, loss of appetite. | Offer bland diet (boiled chicken and rice). Contact your vet immediately. |
| Increased thirst and urination | Your dog drinks more water and urinates more frequently. | Monitor water intake. Alert your vet; this could indicate kidney issues. |
| Lethargy | Unusual tiredness, lack of energy, sleeping more than usual. | Provide a quiet, comfortable space. Report to your veterinarian. |
| Muscle weakness | Difficulty walking, stumbling, or weakness in limbs. | Restrict strenuous activity. Seek veterinary attention promptly. |
| Increased panting | Excessive panting, even when resting. | Provide cool environment. Report to your veterinarian. |
| Skin changes | Thinning of the skin, increased bruising, or slow wound healing. | Gentle handling. Immediate veterinary consultation is recommended. |
| Behavioral changes | Increased aggression, anxiety, or unusual behavior. | Maintain calm environment. Seek veterinary advice. |
These are not all possible side effects. Any unusual changes warrant a veterinary visit. Never administer expired medication without consulting a veterinarian.
