<p>Both Cenforce 100mg and Viagra are FDA-approved medications that can be used to treat erectile dysfunction in men of all age groups. They are similar in chemical formula and effectiveness, but they differ in dosage and delivery method. In addition, a generic version of the medication is available for people who can’t afford the more expensive brand name. While generic drugs are often less expensive, they must meet the same quality standards as their brand-name counterparts. A good place to start is by asking your doctor for a prescription.</p>
