The main difference between sildenafil and Viagra is that Viagra is branded, and sildenafil is the generic, or unbranded, version of it. As both sildenafil and Viagra contain the same active ingredient, sildenafil citrate, they are both effective treatments for men with ED. All generic medication has to contain the same active ingredient to ensure it works in the same way as its brand-name equivalent. Branded medication is often more expensive than generic medication.
Any new brand-name medication will pitch the price relative to the amount of initial research needed to develop and prepare the treatment for marketing approval.

Generic medication can typically be 20-90% cheaper than its brand-name equivalent because of this. The other important factor in pricing is competition: as sildenafil is widely available for manufacture, the price is more competitive (and therefore cheaper). A 2019 study was conducted into the effectiveness of generic medication, which found that there was no difference between how generic and brand-name medication works. Even though generic sildenafil is unbranded, it is still an effective treatment for ED and works in the same way as Viagra. Both Viagra and sildenafil are considered effective treatments for ED. The colour and shape of the pill have no impact on how effective the treatment is. The main difference between generic medication, such as sildenafil, and brand-name medication, such as Viagra, is the purchase price and the appearance of the pill.

Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [ see Drug Interactions (7.4)and Clinical Pharmacology (12.3)].2.5 Dosage Adjustments in Special PopulationsConsider a starting dose of 25 mg in patients > 65 years, patients with hepatic impairment (e.g., cirrhosis), and patients with severe renal impairment (creatinine clearance <30 mL/minute) because administration of sildenafil tablets in these patients resulted in higher plasma levels of sildenafil [ see Use in Specific Populations (8.5, 8.6, 8.7)and Clinical Pharmacology (12.3)].
