No, these aren’t side effects of Januvia.
This drug doesn’t affect your weight. But Januvia is meant to be used together with healthy diet and exercise habits. And these measures may lead to weight changes.
Hair loss isn’t a reported side effect of Januvia. But it can be an early sign of type 2 diabetes, which Januvia is used to treat. More studies are needed to confirm the effects of blood sugar levels on hair loss.
Erectile dysfunction hasn’t been reported as a side effect of Januvia. But this condition can occur with diabetes that’s not well managed.
If you’re concerned about these conditions, talk with your doctor or pharmacist.
