Atopica for Dogs
This is a human heart medication that is used in animals, but has not been specifically approved for them. Because of this some of vets will only prescribe it in relatively severe cases of heart disease. It is a "beta blocker" which is a kind of drug that blocks the effects of adrenaline on the body. This keeps your pet's heart from working too hard, and that can help with a number of heart problems. It is usually used for problems like an irregular heartbeat or rhythm problem, high blood pressure, or other heart issues. Sometimes it's also used for cats with thyroid issues.
Are there any side effects?
Yes, but in general it has been used safely with both dogs and cats. Some pets have allergic reactions to it, so you have to watch out for that. It can cause problems if used with some other medicines, so you need to be sure that your vet is aware of everything your pet is taking. Also, sometimes it can cause the heart rate or blood pressure to be too low. That can cause your pet to faint - if you ever see anything that looks like fainting or falling down while your pet is on this drug, then take the pet to the vet.
