Captopril for Dogs: Benefits, Dosage, Side Effects, and More

Benefits: Captopril is an ACE (angiotensin-converting enzyme) inhibitor primarily used to manage heart conditions in dogs. It is often prescribed for:

Congestive Heart Failure (CHF): Captopril helps reduce the workload on the heart by dilating blood vessels, leading to improved blood flow.
Hypertension: It can lower blood pressure, making it useful for dogs with high blood pressure.
Chronic Kidney Disease: In some cases, Captopril may help improve kidney function by lowering blood pressure, thereby reducing strain on the kidneys.

Dosage: The dosage of Captopril for dogs varies based on the condition being treated, the dog’s weight, and individual response to the medication. Generally:

Typical dosage range: 0.25 to 2 mg per kg of body weight, administered two to three times daily.
Veterinarian guidance: It is essential to follow your veterinarian’s prescription closely, as dosages may need to be adjusted based on the dog’s response and any side effects.

Side Effects: While Captopril can be highly beneficial, it can also cause side effects in some dogs:

Common side effects: These may include lethargy, loss of appetite, vomiting, diarrhea, and weakness.
Serious side effects: Though rare, some dogs may experience kidney dysfunction, low blood pressure (hypotension), or an allergic reaction. Immediate veterinary attention is necessary if these occur.

Considerations:

Regular Monitoring: Dogs on Captopril should be regularly monitored by a veterinarian to check blood pressure, kidney function, and overall health.
Drug Interactions: Captopril can interact with other medications, so it’s essential to inform your veterinarian of all drugs your dog is taking.
Not for Pregnant Dogs: Captopril should not be used in pregnant dogs, as it may cause harm to the developing puppies.
