Clindamycin for Cats Dosage

The dosage of clindamycin for cats depends on the type and severity of the infection, as well as the cat's weight and overall health. Veterinarians typically prescribe clindamycin in the form of capsules, tablets, or liquid suspensions.

Typical Dosage:
The standard dosage is usually between 5.5 mg and 11 mg per pound (10-22 mg/kg) of the cat's body weight, administered every 12 to 24 hours.

Duration of Treatment:
The length of treatment can vary from a few days to several weeks, depending on the infection's nature and severity. Always follow the veterinarian’s instructions regarding the duration of antibiotic therapy.

Clindamycin for Cats Side Effects

While clindamycin is generally safe for cats, it can cause side effects in some cases. Common side effects include:

1. Gastrointestinal Upset:
This can manifest as vomiting, diarrhea, and reduced appetite.

2. Allergic Reactions:
Though rare, some cats may experience allergic reactions such as itching, swelling, or difficulty breathing.

3. Liver and Kidney Issues:
Prolonged use of clindamycin can affect liver and kidney function, so regular monitoring is essential during extended treatment.

Is Clindamycin Safe for Cats?

Clindamycin is considered safe for most cats when used as prescribed by a veterinarian. However, it is crucial to follow the dosage and administration guidelines closely to avoid potential side effects and complications. Cats with pre-existing liver or kidney conditions may require adjusted dosages or alternative treatments. Always inform your veterinarian of any other medications your cat is taking to avoid harmful drug interactions.

Can You Mix Clindamycin with Food for Cats?

Yes, clindamycin can be mixed with food to make administration easier, especially for cats that are difficult to medicate. Here are some tips for mixing clindamycin with food:

1. Liquid Form:
If using a liquid suspension, measure the prescribed dose accurately and mix it with a small amount of your cat’s favorite wet food or a special treat. Ensure the entire mixture is consumed.

2. Capsules/Tablets:
Capsules or tablets can be crushed and mixed with food, but it’s essential to ensure the cat consumes the entire mixture to receive the full dose. Check with your veterinarian before crushing tablets, as not all medications are safe to alter.

What Cannot be Mixed with Clindamycin?

Certain substances and medications should not be mixed with clindamycin due to potential interactions or reduced efficacy. These include:

1. Antacids:
Antacids containing aluminum, calcium, or magnesium can interfere with the absorption of clindamycin. Avoid administering antacids within two hours of giving clindamycin.

2. Other Antibiotics:
Some antibiotics, such as erythromycin, can interact with clindamycin, reducing its effectiveness. Always inform your veterinarian of any other medications your cat is taking.

3. Vitamin and Mineral Supplements:
High doses of certain vitamins and minerals, particularly calcium and iron, can affect the absorption of clindamycin. Consult your veterinarian before giving your cat any supplements.

Monitoring and Follow-Up

Regular monitoring and follow-up appointments with your veterinarian are crucial during clindamycin treatment. This ensures the infection is responding to the medication and helps detect any potential side effects early. If your cat shows any signs of adverse reactions or if the infection does not improve, contact your veterinarian immediately.


Clindamycin is a potent and effective antibiotic for treating various bacterial infections in cats. When used correctly, it can significantly improve your cat’s health and well-being. Always follow your veterinarian’s instructions regarding dosage and administration, and monitor your cat for any side effects. With proper care and attention, clindamycin can be a valuable tool in maintaining your cat’s health.
