Can you take toviaz (fesoterodine) when pregnant ?

Category C: Toviaz (fesoterodine) is pregnancy category C which means that it is not known whether it will cause the baby harm or not but the possibility cannot be ruled out. Category C drugs are generally only used if they are necessary and not using them will cause harm. The precautionary principle applies. If you don't know it is safe don't use it if you don't have to. Hope this helps.
