Order FDA-Approved Sildenafil — Same as Viagra, Up to 90% Cheaper
Available in 25mg, 50mg, and 100mg strengths
Generic Sildenafil contains the same active ingredient as branded Viagra but at a fraction of the cost. Once Pfizer's patent expired, other pharmaceutical companies were able to produce bioequivalent versions of Sildenafil Citrate, offering the same effectiveness and safety profile at more affordable prices. All generic medications sold in the US must be approved by the FDA and meet the same rigorous quality standards as brand-name drugs.
Generic medications contain the same active ingredients as their branded counterparts and undergo rigorous FDA testing to ensure they meet the same quality and safety standards. Generic Sildenafil must demonstrate bioequivalence to Viagra, meaning it works in the same way and produces the same clinical results. The lower price reflects savings on marketing and development costs, not a difference in quality.
Sildenafil is a PDE5 inhibitor that increases blood flow to the penis by relaxing blood vessel walls. When sexually aroused, this enhanced blood flow helps achieve and maintain an erection. The medication typically takes effect within 30-60 minutes and lasts for 4-6 hours. Sexual stimulation is required for the medication to work.
The recommended starting dose is 50mg, taken approximately one hour before sexual activity. Based on effectiveness and side effects, the dose may be adjusted to 100mg or reduced to 25mg. Take no more than one dose per 24-hour period. For best results, take on an empty stomach or after a light meal.
Important: Sildenafil requires sexual stimulation to work. It does not increase sexual desire but helps achieve an erection when aroused.
Generic Sildenafil is suitable for men over 18 with erectile dysfunction. However, consult a healthcare provider before use if you have heart problems, recent heart attack or stroke, blood pressure issues, liver or kidney disease, or take nitrate medications.
Side effects are typically mild and may include headache, facial flushing, indigestion, nasal congestion, and visual changes (blue tint). These effects are temporary and usually subside within a few hours. Seek immediate medical attention for erections lasting more than 4 hours, sudden vision loss, or chest pain.
Yes — completely. The FDA requires generic medications to be bioequivalent to their brand-name counterparts. Generic Sildenafil must produce the same blood levels, work in the same timeframe, and deliver the same clinical results as Viagra. Read: Generic Sildenafil vs Brand Viagra
Generic Sildenafil typically costs 40–90% less than branded Viagra. While brand Viagra can cost $15–70 per pill, generic Sildenafil is available from Promedic starting around $5.99 per tablet. The savings can be hundreds of dollars per month.
Take Sildenafil 50mg approximately 1 hour before sexual activity on an empty stomach or after a light meal. You may increase to 100mg or decrease to 25mg based on response. Never take more than one dose in 24 hours. Guide: How to Take Sildenafil
