Megestrol Acetate 20mg Tablets for Pets

Hormonal Therapy for Estrus Suppression and Appetite Stimulation

Megestrol acetate is a synthetic progestin used in veterinary medicine to manage hormone-related conditions in female dogs and cats. At 20mg strength, these tablets offer an effective non-surgical solution for estrus suppression, false pregnancy (pseudopregnancy), behavioral management, and occasionally appetite stimulation in companion animals. This product is veterinarian-prescribed and primarily used for canine and feline reproductive health, aligning with treatment protocols for animals not suitable for spaying or requiring temporary hormonal regulation.

Unlike many over-the-counter hormonal therapies, HardyPaw’s Megestrol 20mg Tablets deliver precise dosing, superior formulation consistency, and trusted safety—making it a preferred choice among pet owners and veterinarians alike.

All prescription items are Non-Refundable and Non-Returnable.

What Are the Benefits of Megestrol Acetate 20mg Tablets for Dogs and Cats?

Megestrol tablets are especially useful when spaying is not an option due to age, health issues, or breeding plans. The key therapeutic uses and benefits include:

• Estrus Suppression (Heat Prevention): Temporarily halts the estrous cycle in intact female dogs and cats, reducing mating behavior and bleeding.

• Treatment of False Pregnancy (Pseudopregnancy): Alleviates symptoms like nesting, milk production, and behavioral changes caused by hormonal imbalance.

• Behavioral Modification: Helps manage hormone-driven aggression, restlessness, and mounting behaviors.

• Appetite Stimulation in Cats (Off-label Use): May aid in increasing appetite in cats suffering from chronic illnesses like cancer or renal disease.

• Non-Surgical Reproductive Control: Offers an alternative to spaying in cases where surgery is not feasible or desirable.
