Viagra is a name brand version of Sildenafil tablets. Viagra is used for treating the symptoms of erectile dysfunction (ED). It helps people get erections easier, and stay erected longer for sexual activity. Viagra is a relatively safe and affordable treatment option for erectile dysfunction. It is usually one of the first things doctors prescribe when you’re diagnosed with ED.
Viagra does not make you get erections spontaneously. Sexual stimulation is required.

How Does Viagra Work
Sildenafil works by balancing enzymes that are essential for creating and sustaining an erection. When aroused, the penis produces nitric oxide and an enzyme that helps with achieving an erection. As a PDE5 inhibitor, sildenafil prevents this enzyme from breaking down, promoting increased blood flow into the penis and reducing blood flow out. This results in a longer-lasting erection, with effects lasting 24-36 hours, making it more effective than other ED medications.
Viagra vs Generic Sildenafil: What’s the Difference?
Both Viagra and its generic versions, such as Sidegra, contain the same active ingredient: sildenafil citrate. This is the key component that makes Viagra effective, as it increases blood flow to the penis to help treat erectile dysfunction (ED). In essence, they are the same medication marketed under different brand names.
Viagra is the original branded version developed by Pfizer, the company that first introduced sildenafil citrate. Generic alternatives use the exact same active ingredient and are manufactured to meet similar quality and safety standards, but are sold under different names, often at a lower cost.
When sourced from legitimate and licensed providers, both branded Viagra and generic sildenafil are equally effective and safe. Manufacturing of genuine medications are highly regulated and regularly tested that the quality remains the same. The primary difference lies in the manufacturer and branding, rather than how the medication works.
Recommended Dosage & How to Use Viagra
Standard recommended dose of Viagra is 50 mg, taken 30–60 minutes before sex.
This 50mg dosage works well for a lot of people, but you may need a stronger dosage if you have a more moderate case of erectile dysfunction. Your doctor may adjust based on response and tolerance. Other common dosage for Viagra are:
- 25 mg - Suggested for beginners or older adults that get strong side effects from the standard dose.
- 100 mg - Suggested for people who does not respond to the 50mg dose.
Whether you're prescribed with lowest or highest dose, Viagra should be only taken once per day maximum. Stronger dosage does not mean Viagra will work better or give you harder erection. Do not increase the dosage on your own. Consult with your doctor if you have unpleasant side effects or if the dosage you get does not work well.
Side Effects and Safety Considerations
Common side effects of sildenafil include headaches, muscle aches, back pain, nasal congestion, dizziness, facial flushing, rashes, upset stomach, nausea, blurred vision, and lowered blood pressure. If any of these persist or become bothersome, consult your healthcare provider.
Serious side effects, though rare, can include sudden vision loss, hearing issues, or priapism (an erection lasting more than four hours). These require immediate medical attention. Seek emergency care if you experience allergic reactions like hives or trouble breathing.
There are also some serious side effects that you will need medical attention for such as priapism (when an erection lasts more than 4 hours), vision loss, or hearing loss.
If you are taking nitrate medications, do not take Viagra. This may cause a dangerous drop in blood pressure.
Do not take Viagra more than you are prescribed in 24 hours
