What are the serious side effects of liothyronine?

While less common, the most serious side effects of liothyronine are described below, along with what to do if they happen.

Severe Allergic Reactions. Liothyronine may cause allergic reactions, which can be serious. Stop taking liothyronine and get help right away if you have any of the following symptoms of a serious allergic reaction.

• Breathing problems or wheezing
• Racing heart

Heart Problems. Liothyronine may cause your heart rate to increase or become abnormal. You may also have chest pain. Your risk may be higher if you are older, have heart problems, or if you take too much liothyronine. Tell your health care provider right away if you notice any of the following.

• Chest pain or pressure
• Fast or abnormal heartbeat
• Shortness of breath

Weak Bones. Liothyronine may cause your bones to become weaker, leading to reduced bone density (osteopenia). It may also cause a more serious condition called osteoporosis, which can cause your bones to break (fracture) more easily. You may be at a higher risk of this if you take too much liothyronine or if you have gone through menopause. Tell your health care provider if you break a bone, and get a bone mineral density test if one is ordered for you. Buy T3 40mcg Tablets
