Hello , My father has been advised to take Metapure XL 50 , after a thorough check up and angiogram by one of the cardiologist which he has been continuing from March .After getting checked up by another doc he was advised to take 25mg of the same medicine, we are unable to get tablet for 50mg here, rather 25 mg is available . Due you advise taking 2 tabs of 25mg at a time to compensate for 50 mg or I shall start taking 25mg . Also if 2 tabs are to be taken , do we take in morning and evening (twice a day) .
