Can I use Siofor XR 1000 mg interchangeably with Siofor 1000 mg?

No, they are not the same forms. The difference between them lies in the way the active substance is released in the body. Siofor XR 1000 mg is a prolonged-release tablet, which means that it releases metformin gradually over a longer period of time. In contrast, Siofor 1000 mg is a regular tablet that releases metformin quickly after taking it.
