As a doctor we do not recommend No-Spa tablets (Drotaverine) to use during pregnancy, especially during the first trimester, because studies on the safety of Drotaverine during pregnancy are limited, it is considered a category C medication by the US Food and Drug Administration (FDA), meaning there may be potential risks to the fetus based on animal studies, but human studies are limited or lacking.
Is it advisable for my pregnant wife to take No-Spa tablets to alleviate spasms and pain?
