Meglumine Antimoniate
Also known as: Glucantime, Glucantim
Treatment for leishmaniasis requires a strong commitment. Here is what you need to know: * **Long and Costly Treatment**: The treatment protocol is prolonged (often lasting months when combined with other oral medications) and the medication can be expensive. * **Management, Not a Cure**: It is highly unlikely that this drug will completely eradicate the parasite from your dog's body. The goal is to put the disease into remission and give your dog a good quality of life. Relapses can occur. * **Injection Site Reactions**: Because this medication is given by injection, your dog may develop soreness, swelling, or small abscesses at the injection sites. * **Watch for Side Effects**: Monitor your dog closely for loss of appetite, vomiting, or extreme tiredness. If you notice these signs, contact your veterinarian immediately, as the drug can occasionally affect the kidneys or liver.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

Cautions & contraindications
- Previous hypersensitivity to meglumine antimoniate
- Severe renal, hepatic, or cardiac failure (relative contraindication; weigh risks vs. benefits)
- Severe renal impairment
- Hepatic failure
- Cardiac disease
- **Extreme caution** is advised in patients with pre-existing **renal, hepatic, or cardiac insufficiency**. * **Renal Impairment**: Decreased renal function can lead to significant drug accumulation and an increased risk of severe toxicity. In dogs with severe renal failure (IRIS stages III-IV), correction of fluid and acid-base imbalances prior to treatment with allopurinol alone is recommended before considering antimonials. * **Hypersensitivity**: Hypersensitivity reactions have been reported in humans; avoid in patients with known allergies to the drug. * **Pregnancy**: Teratogenic effects (fetal resorptions, bone abnormalities) have been noted in animal models. Weigh risks versus benefits carefully.
Drug interactions
