About this product

What is Megestrol?

Megestrol is a synthetic chemical similar to the female hormone progesterone and is used to postpone estrus (female's heat cycle) and help end a false pregnancy. Megestrol requires a prescription from your veterinarian, and is sold per tablet.

For:

Dogs

Benefits:

  • Easy to administer
  • FDA approved for use in dogs

How it Works:

Megestrol is a female hormone that through its actions regulates the female heat cycle and can be used to alleviate false pregnancy.

Cautions:

Megestrol should not be used in pregnant animals. Tell your veterinarian if your pet is being given insulin. Megestrol may decrease the effect of insulin and your pet's blood sugar may increase. Also contact your veterinarian if your pet experiences increased thirst or urination, depression, mammary gland enlargement, temperament changes, vaginal discharge, vomiting, or yellow gums while being treated with Megestrol. Other drugs may also interact with Megestrol, so talk to your veterinarian or pharmacist before using any prescription or over-the-counter medications.

Brand Name:

Ovaban (Schering-Plough)

Generic Name:

Megestrol

What is megestrol:

Megestrol is a synthetic chemical similar to the female hormone progesterone. Megestrol is a prescription medication FDA approved for use in dogs. Megestrol is available as 20mg scored tablets. Megestrol is used to postpone estrus (female heat cycle) and to alleviate false pregnancy. When used to postpone estrus, the dose and duration of treatment depends on the stage of the cycle when therapy is begun.

What should I discuss with my veterinarian before giving megestrol:

What is the most important information I should know about megestrol:

Notify your veterinarian if your pet develops any side effects while taking megestrol.

How should this medication be given:

Give this megestrol exactly as directed by your veterinarian. If you do not understand the directions, ask your pharmacist or veterinarian to explain them to you. Allow pet to drink plenty of water. Megestrol tablets may be given whole or crushed and mixed in food. Store megestrol at room temperature, away from moisture and heat.

What should I avoid while giving megestrol:

There are no restrictions on food or activity during treatment with megestrol unless your veterinarian directs otherwise. Do not give megestrol to pregnant dogs or dogs with mammary tumors. Megestrol should not be given for more than two consecutive treatments.

What are the possible side effects of megestrol:

If any of the following serious side effects occur, stop giving megestrol and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing, swelling of the lips, tongue, face, or hives), sudden severe headache; changes in vision; swelling in a leg. Other less serious side effects may also occur. Talk to your veterinarian if your pet experiences nausea or vomiting, dizziness, mild shortness of breath, weakness, headache, vaginal bleeding, sweating, and insomnia. Side effects other than those listed here may also occur. Talk to your veterinarian about any side effect that seems unusual or that is especially bothersome.

Breed Shirt hair domestic
Works like a charm!
I adopted a cat 5 years ago who had some type of skin irritation that caused her to lick, chew and pull at her hair along one side and down her back. She had scabs covering a lot of the areas where she created open wounds on herself. This medication was prescribed and, within a week, I noticed significant improvement! Due to the potential side effects, I only administered Megestrol until the condition cleared up and hair started growing back. As odd as it is, she only seems to start the licking and chewing at a certain time of the year. It's not a year-round problem. It's quite baffling to me and to the vet. When this happens, I medicate her for a few weeks and then stop. Megestrol clears up the condition and she is a happy cat!

so helpful....
My cat had a tendency to lick and scratch himself raw and bloody and I worried about infections. My vet suggested this and if it worked my cat would have to be on it the rest of his life. Gave it a shot and lo and behold it worked!!! 1/4 every day for 2 weeks to start and cutting it back till it became just once a week. Only side effect so far is that my cats gained a lot of weight =/ but the plus side is no more licking till he's raw and sore anymore and no worries of infection!

This product does what my Vet intended it for.
My cat had itchy, scabby bumps around her neck, head and down her back near her tail. She was miserable. After taking one 1/4 pill (5mg.) twice a week the sores cleared up! My vet said she has a hormonal imbalance. It also helps her mood. Before being on this medication, she would constantly attack my other cat. After a few months of giving it to her, it dawned on me that I use to administer this exact same medicine to a person I was caretaking. She was taking it to help improve her appetite. So, be ready for a hungrier then usual animal! ~Watch my video of Kat to see how well she's doing now~

Ovaban
Vet gave "ovaban" to my kitty for a skin condition; said it is a fungal condition. Montgomery pulled out his hair and bit at his skin until it was gooey and runny! Horrible. I quarter a 20 mg pill and his condition totally cleared up.

I have not yet tried this product but would like to comment on the above review. This is not the same product as the human Plan B. Plan B is levonorgestrel, NOT Megestrol. Megestrol is used to treat other medical conditions in humans not related to pregnancy prevention. Do not purchase this product thinking that it is going to prevent pregnancy.
