Sildenafil, an ingredient in Bigfun , is a member of the class of medications known as phosphodiesterase type 5 (PDE 5) inhibitors. It facilitates blood vessel relaxation, increasing blood flow to the penis.
When taking Bigfun, avoid having large meals as this may postpone the start of the medication’s effects. Tell your doctor if you have any liver, kidney, or heart issues before taking Bigfun. Additionally, if you take medication and have pulmonary arterial hypertension (PAH), you must let your doctor know.
