Hello, thanks for asking your query.
Your doctor had prescribed Meto ER 50 mg, CTD ( chlorthalidone
6.25mg) for control of blood pressure. Side effects of Meto ER can be giddiness, lightheadedness
, stomach disturbance, at times difficulty in breathings. Please do get in touch with your doctor if you get any of this side effects. But the drug is very well tolerated so dont worry.
