When it comes to third-line agents, Henry said, another factor may be price. Some medications aren't always available in generic form, which may make them significantly more expensive.
If you have specific concerns, such as weight gain or cost, Henry said it's important to bring these concerns to your doctor's attention when you're talking about adding another diabetes medication.
"If a third medication is needed because glucose control isn't adequate, get one that's tailored to your unique needs," he advised.
"We think that the results of this study offer a wide range of choices of anti-hyperglycemic agents that might be used as the third option in patients with type 2 diabetes not controlled using metformin and sulphonylurea based on efficacy. The final decision would depend on the effects in weight and risk of hypoglycemic episodes," said Gross.
