Sevel Sevelamer Carbonate Levothyroxine Sodium
ModerateTaking Sevelamer Carbonate together with Levothyroxine may, in very rare cases, lead to an underactive thyroid (hypothyroidism). This was seen in people who took levothyroxine with sevelamer hydrochloride, a medicine with the same active part as Sevelamer Carbonate. Because of this, your doctor should check your thyroid stimulating hormone (TSH) level more often while you take both medicines.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
