Sulfadimethoxine
Also known as: Albon, Di-Methox, Amtech
**Important Guidelines for Pet Owners:** * **Water is Crucial:** Ensure your pet has access to plenty of fresh drinking water at all times while on this medication. This helps prevent the drug from forming crystals in the kidneys. * **Watch the Eyes:** In dogs, this medication can occasionally decrease tear production, leading to 'dry eye'. Contact your veterinarian if you notice your dog squinting, rubbing their eyes, redness, or a thick yellow/green eye discharge. * **Monitor for Reactions:** Stop the medication and contact your vet immediately if your pet develops a skin rash, unexplained fever, joint stiffness/limping, or severe vomiting. * **Administration:** Can be given with or without food. If your pet vomits after receiving the dose on an empty stomach, try giving future doses with a small meal or treat. * **Pregnancy:** Inform your veterinarian if your pet is pregnant or nursing, as this drug can cross the placenta and enter the milk.
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
- Hypersensitivity to sulfonamides, thiazides, or sulfonylurea agents
- Severe renal or hepatic impairment
- Doberman Pinschers (highly susceptible to poly-systemic immune complex disease)
- Dehydrated patients (increased risk of crystalluria)
- > **Breed Warning:** Doberman Pinschers are highly susceptible to sulfonamide-induced poly-systemic immune complex disease (presenting as polyarthritis, fever, uveitis, glomerulonephropathy). Use is generally contraindicated in this breed. * **Renal/Hepatic:** Use with extreme caution in patients with diminished renal or hepatic function, or urinary obstruction. * **Hydration:** Maintain adequate hydration and urine flow to prevent crystalluria and renal tubular obstruction. * **Tissue Irritation:** Because solutions are highly alkaline, IM or SC injections can cause significant tissue irritation and necrosis. * **Ruminants:** Oral administration can temporarily depress normal cellulytic function of the ruminoreticulum. * **Pregnancy:** Potentially teratogenic at high doses. Weigh risk vs. benefit. Crosses the placenta and is distributed into milk.
Drug interactions
- Antacids: May decrease the oral bioavailability of sulfonamides if administered concurrently.
