I take atenolol and hydrochlorothiazide for blood pressure. As I was taking my daily dose of both, the hydrochlorothiazide pill fell into my half-full water bottle and dissolved. I drank the water pretty soon after but am not sure if the medication will work the same way as some pills don't effect you the same way when dissolved. Can anyone shed light on this and help determine if it's safe to take another pill today or wait until tomorrow?
