Metlong helps in weight loss by reducing appetite and food intake. It also increases the insulin sensitivity in your body to work more effectively. This lead to decreased glucose production increases the use of glucose and decrease the fat deposition further helps in weight loss. However, Metlong is not approved for weight loss, this is an off-label use.

Yes, Metlong can cause low blood sugar (hypoglycemia). However, this can also occur if you delay or miss a meal, drink alcohol, exercise more than usual, can't eat due to stomach upset, and taking other antidiabetic medicine with metformin. So, regular monitoring of blood glucose level is needed and be cautious of symptoms of hypoglycemia, always keep glucose-rich food with you.

Yes, you can take Metlong with a beta-blocker. People with diabetes tend to develop heart disease or stroke at an earlier age than the general population. One reason for this is that high glucose levels increase your risk of high blood pressure (hypertension). No harmful interactions are seen between them. However, a recent study suggests that beta-blockers can decrease the plasma level of Metlong and long-term use can increase lactic acid and uric acid in the blood.

Lactic acidosis associated with Metlong treatment is a rare but fatal adverse effect. Lactic acidosis appears to result from biguanide interference causing an increase in production and decrease in clearance of lactate leading to higher cellular lactate levels. A decrease in pyruvate carboxylase activity, the rate-limiting enzyme in the formation of glucose from lactate, can also decrease hepatic metabolism of lactate. leading to increasing lactic acidosis. Signs and symptoms of Metlong induced lactic acidosis are nonspecific and include anorexia, nausea, vomiting, altered level of consciousness, hyperpnoea, abdominal pain, and thirst.

Metlong can be taken forever, diabetes is a progressive disease it's possible that more medication and/or insulin may eventually need to be added to the regime.
