Stanozolol
Also known as: Winstrol-V, Winstrol, Menabol, Neurabol, Stanol, Stromba, Strombaject
Stanozolol is an anabolic steroid used to help pets gain weight, build muscle, or treat certain types of anemia. * **Administration:** Tablets may be crushed and administered with food to make dosing easier. * **Safety Warning:** This medication can cause severe liver damage, especially in cats. Your veterinarian will likely recommend regular blood tests to monitor liver function. * **Storage & Handling:** Because of the potential for human abuse, stanozolol is a **controlled substance**. It must be kept in a secure area, strictly out of the reach of children and unauthorized individuals. * **Side Effects:** Watch for signs of fluid retention (swelling), changes in behavior (such as increased aggression), or yellowing of the eyes/gums (jaundice), and report them to your veterinarian immediately.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

Teratogenicity clearly outweighs any possible benefit. Contraindicated in pregnant animals. Use with extreme caution in nursing patients as it is unknown if it is excreted in maternal milk.
Drug interactions
- Anticoagulants (heparin, warfarin): Anabolic agents may potentiate the effects of anticoagulants; monitoring of INR/PT and dosage adjustment of the anticoagulant are recommended.
- Corticosteroids: Anabolics may enhance the edema that can be associated with ACTH or adrenal steroid therapy.
- Insulin: Anabolics may decrease blood glucose and decrease insulin requirements; diabetic patients receiving insulin may need dosage adjustments.
