Guide To The Side Effects Of Metformin

Fever And Chills

In rare cases, patients will experience a fever and chills as side effects of metformin. A fever refers to a body temperature of 100.4 degrees Fahrenheit or higher. Patients have a high fever when their temperature is at least 103.1 degrees Fahrenheit. Chills, on the other hand, refer to an individual feeling extremely cold even when their body temperature dictates otherwise. Patients with chills often shiver and deal with clammy skin at the same time. Patients need to talk to their doctor immediately if they deal with either a fever or chills on metformin. This is particularly vital for chills, which can be a warning sign of lactic acidosis, another rare and severe side effect of this medication.
