Let's take a minute to talk about your medication. 

This is Janumet. Each tablet contains two medicines called 'metformin' and 'sitagliptin'. 

Janumet helps keep blood sugar at normal levels in patients with type 2 diabetes. Over time, this may help prevent or postpone serious health problems from diabetes. 

Your doctor may start you on a low dose. This should help reduce any nausea or stomach upset that might happen in the beginning. Also, it's important to take each dose with a meal. You should always swallow the tablet whole, and never break, crush or chew them. 

Common side effects include mild diarrhea, headache or a head cold. Low blood sugar could also happen. This could affect your concentration and reaction time. You should be aware of this before doing activities that require you to be alert. You may need emergency help for blood sugar that is very low or high. Make sure to talk to your doctor about checking your blood sugar and when to get help. 

As with any medicine, rare but serious side effects can occur. With Janumet, these include allergic reactions, or problems with your pancreas or kidneys. It could also cause a build-up of too much lactic acid in the body. You should read the Medication Guide for more information. To help keep this medicine safe for you, your doctor will follow you closely and will order blood work. You can help by drinking fluids to stay hydrated, and by drinking little or no alcohol. You should call your doctor right away if you notice unusual changes to your body, or if you do not feel well. 

For best results with Janumet, take it exactly as prescribed. Also, follow the diet and exercise program recommended by your doctor.
