Compounded Fosfomycin (Monurol) For Dogs & Other Pet Animals

Fosfomycin is an antibiotic medication used animals and humans to treat infections. It is used in animals to help a variety of conditions. It is often used to treat multidrug-resistant UTIs in dogs. This medication is nephrotoxic to cats and should not be given to this species. It is important to remember that even though the medication takes effect within as little as 1-2 hours after being given, the true benefits of the medication to your animal’s health may not be seen outwardly. It may take 1-2 days of taking this medication for you to see an improvement in your animal’s condition. Fosfomycin does require a prescription from your veterinarian in order to be dispensed. You and your veterinarian should discuss if this is the best option for your pet.

Fosfomycin is given orally and can be compounded to the desired strength and flavor that best suits your patient/pet. We compound this medication into suspensions and capsules. This medication is best given with or without food. If the patient vomits after receiving the dose on an empty stomach, the next dose should be given with food to decrease GI upset. If you miss a dose do not double up on the medication. Wait until the next dose is due and follow the normal dosing schedule as directed. This medication should be avoided in animals that are pregnant or nursing unless the benefits to the mother outweigh the risks to the offspring. You and your veterinarian should discuss if this is the best option for your pet.

Common side effects of Fosfomycin include vomiting, diarrhea, and lack of appetite. If the patient experiences excessive itchiness, swelling of tongue or face, trouble swallowing, or bloody diarrhea, please contact your veterinarian/doctor immediately as these symptoms may indicate a serious reaction or a dose that is too high. Overdoses of this medication can be serious. If you suspect an overdose, contact your veterinarian or poison control.
