FDA warns of joint pain from popular diabetes drugs

WASHINGTON, D.C. (WPVI) -- A popular group of drugs for type 2 diabetes is in the spotlight.

The FDA has issued a new warning about their potential side effects.

The agency has added a new warning to the labels of all the drugs in a class of medications known as DPP-4 inhibitors.

That includes the brands Januvia, Janumet, Onglyza, Tradjenta, Glyxambi, Jentadueto, Nesina, Kazano, Oseni, and Kombiglyze XR.

It's a newer class of medications.

The FDA says they may cause severe joint pain that can be disabling.

The joint pain wasn't seen during the clinical trials, however, now that the drugs are more widely taken, it has appeared in reports to the FDA's Medwatch incident reporting program.

The agency says patients started having symptoms from 1 day to years after they started taking the drugs.

After the patients discontinued the medications, the symptoms diminished, usually in less than a month.

If you take one, don't stop taking it. But you should talk to your healthcare provider about your risks.

If you develop severe joint pain, let them know right away.

And report your trouble to the FDA MedWatch program.
