Stop bacteria in its tracks with Dicloxacillin Capsules. While dicloxacillin is not intended to treat viral infections, like common cold and flu, it does work to help fight a variety of bacterial infections. This penicillin-type, broad-spectrum antibiotic comes in an easy-to-administer capsule form and is frequently given to treat infections while awaiting lab results.

Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.


Dicloxacillin is used to reduce the development of drug-resistant bacteria and maintain the effectiveness of Dicloxacillin sodium capsules and other antibacterial drugs, Dicloxacillin sodium capsules should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

Possible Side Effects

Adverse effects with penicillins are usually not serious and have a relatively low frequency of occurrence. Hypersensitivity reactions unrelated to dose can occur with these agents and can manifest as rashes, fever, seizures, anemias, or full-blown anaphylaxis.

When given orally, penicillins may cause GI effects such as anorexia, vomiting, diarrhea. Because the penicillins may also alter gut flora, antibiotic-associated diarrhea can occur and allow superinfections in the colon.

Toxicity has been associated with very high doses or very prolonged use. Although the penicillins are not considered hepatotoxic, elevated liver enzymes have been reported. Other effects reported in dogs include tachypnea, dyspnea, edema, and tachycardia.

Other side effects are possible. Contact your veterinarian at once if your pet is acting ill in any way after taking Dicloxacillin Capsules.

Drug & Food Interactions

Before taking Dicloxacillin, tell your veterinarian if your pet is allergic to it; or to penicillin or cephalosporin antibiotics. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Before using this medication, tell your veterinarian your pet's medical history, especially regarding kidney disease. Other drug interactions may occur. Please provide your vet with a list of any supplements or drugs your pet is taking.


Dicloxacillin sodium capsules should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When dicloxacillin sodium capsules are prescribed to treat a bacterial infection, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may: (1) decrease the effectiveness of the immediate treatment, and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by dicloxacillin sodium capsules or other antibacterial drugs in the future. Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, dogs can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, see your veterinarian as soon as possible.
