Hamare expert ka khayal (Verdict)

Glucophage (Metformin) is the standard first medicine for type 2 diabetes — cheap, effective, with proven heart benefit. Januvia (Sitagliptin) is added when metformin alone doesn't reach the target HbA1c. Modern Pakistani guidelines now sometimes prefer SGLT2 inhibitors or GLP-1 agonists as add-ons for patients with heart or kidney disease — discuss options with an endocrinologist.
