Methamazole Contraindicated with HCM Heart Meds and Blood Thinners
Methamazole, given to cats for hyperthyroidism, is contraindicated with atenolol, blood thinners, and other meds. Methimazole decreases or prevents the effectiveness of other drugs. If your cat is on meth, I'm not sure what would be the best approach. If your cat's thyroid is overacting, eating iodine free foods such as Hill's y/d and not eating regular food that has iodine, will help decrease thyroid levels. Meth should be used if the thyroid level doesn't improve with a diet. Your cat may need some meds such as atenolol more often if also on meth. Always discuss this with your vet/cardio and watch for symptoms that the beta blocker isn't working. These could be weakness, fainting, lethargy, even breathing too hard because the blood pressure and or heart rate have increased or have dropped.
