No, taking fildena 100mg or any medication containing sildenafil is not safe for pregnant women. Sildenafil is primarily used to treat erectile dysfunction and pulmonary arterial hypertension, but it is not approved for use during pregnancy. It may pose risks to both the mother and the developing fetus. Sildenafil can affect blood flow, potentially impacting the placenta and the baby's growth. It's essential for pregnant women to consult their healthcare provider for safe and appropriate treatments if needed, as self-medication with sildenafil or any medication during pregnancy can lead to serious complications and harm to the unborn child.Check also online medicine store site.
