Cenforce 100 mg and Viagra are both effective treatments for erectile dysfunction because they contain the same active ingredient, Sildenafil Citrate. Cenforce 100 mg is a more affordable generic version of Viagra, and in most cases, they can be used interchangeably. However, it’s important to consult a healthcare provider to ensure the medication is appropriate for your needs, especially if you have underlying health conditions or are taking other medications. The effectiveness, side effects, and dosing are very similar, so they can be used interchangeably for most men.
