Vigora 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Vigora 100 mg should not be taken by individuals who are allergic to sildenafil citrate or any other ingredients in the medication. It's also contraindicated to take Vigora 100 mg with certain medications, particularly those containing nitrates, as this can lead to a sudden and potentially dangerous drop in blood pressure.
