Diphenhydramine HCL should be used with caution in pets suffering from angle-closure glaucoma, prostatic hypertrophy, bladder neck or pyloroduodenal obstruction, COPD, hyperthyroidism, cardiovascular disease, or hypertension. Should only be used in pregnant patients when the benefits outweigh the risks. Taking diphenhydramine with CNS depressants might cause excessive depression of the central nervous system. MAOI inhibitors might intensify the anticholinergic effects of diphenhydramine. Diphenhydramine might overly enhance the effects of epinephrine, and counteract the anticoagulant effects of heparin or warfarin. Possible side effects of diphenhydramine HCL are CNS depression, dry mouth, urine retention, vomiting, diarrhea, and loss of appetite. The sedative effects of diphenhydramine might lessen over repeated uses. In some cats, a paradoxical CNS excitation might occur.

Common side effects are drowsiness and dry mouth. Your pet may also develop urinary retention. Other side effects that are less common include diarrhea, vomiting and lack of appetite. If any symptoms appear to distress your animal, contact your veterinarian. Always tell your veterinarian all the medicines your pet is on before adding new medications.

Do not use if cat or dog is pregnant or nursing. Do not administer to pets suffering from glaucoma, high blood pressure, urinary obstruction, and prostate disease. Use with caution when given with other CNS (central nervous system)-depressant drugs such as tranquilizers or barbiturates.
