Tadalista 40, which contains tadalafil, is a medication primarily used to treat erectile dysfunction and symptoms of benign prostatic hyperplasia. During pregnancy, its safety is not well-established. Tadalista 40 mg is classified under FDA pregnancy category C, meaning animal studies have shown potential risks to the fetus, but there are no well-controlled studies in pregnant women. Therefore, it should only be used during pregnancy if the potential benefits outweigh the risks. Pregnant women should avoid taking Tadalista 40 unless prescribed by a healthcare provider after careful consideration of their condition. Always consult a healthcare professional before using any medication during pregnancy.
