Viagra overview
What is Viagra (Sildenafil)?
Viagra® is a branded version of Sildenafil that became the first FDA-approved treatment for erectile dysfunction (impotence). Viagra helps men get an erection by increasing blood flow to the penis in response to sexual stimulation. It can also help in maintaining an erection for a long time. It belongs to the PDE5 inhibitors, drugs that block the enzyme PDE5, thereby increasing cGMP and relaxing blood vessels and improving blood flow.
Side effects of Viagra you should know about
Common Sildenafil side effects reported include:
- Headache
- Flushing (redness in the face and neck)
- Priapism (prolonged and painful erection of the penis)
- Indigestion
- Nasal congestion
- Eye problems
- Back pain
- Muscle pain
This is not a complete list of potential side effects. Consult your doctor immediately if you experience any serious side effects.
How do I take Viagra?
Typically, it takes 30 to 60 minutes for Viagra (Sildenafil) to start working. For most men, taking the medication 30-60 minutes before sexual activity is ideal. However, the timing may be different for you to achieve and maintain an erection. For optimal results, follow your healthcare provider’s recommendations.

Sildenafil 100mg online — Is it right for the treatment of erectile dysfunction?
The standard dose of Sildenafil is 50 mg, usually prescribed once a day. A dose of 100 mg is often prescribed if a 50 mg dose is ineffective. Increasing the dose to 100 mg of Sildenafil may increase the likelihood of experiencing harder erections, particularly in men with severe ED. One study compared the effects of 50 mg and 100 mg of Sildenafil on patients with erectile dysfunction. Patients with higher dosage reported better frequency of sexual intercourse and sexual performance compared to lower dosage.
Only a licensed physician can determine the correct dose of Viagra/Sildenafil depending on your age, health, and needs. You can get an online Sildenafil prescription safely through Your Doctors Online to treat erectile dysfunction.

Are you wondering where to order Sildenafil tablets in the USA? Prescription products like Viagra and other ED treatment medications are available only with a licensed physician’s prescription. Once you get a prescription, you can get Viagra from local and online pharmacies by paying out of pocket.
Viagra vs Cialis vs Levitra: Which is better for Erectile dysfunction?
Viagra might work better for you than other ED medications. However, it is not essentially better or worse than other erectile dysfunction medications like Levitra or Tadalafil (generic for Cialis). Although they are from the same general drug class, they have different onset, dosage, duration of effect, and side effects. Talk to your medical provider to find out if a Sildenafil prescription is better for you compared to other medications. Below is a detailed comparison of Viagra with Tadalafil (clinically equivalent to brand-name Cialis) and Vardenafil (Levitra).

What is the recommended dose of Viagra®?
In the USA, oral tablets of Viagra come in different strengths: 20 mg, 25 mg, 50 mg, and 100 mg. 20 mg (brand: Revatio) and 25mg are the lowest doses, and 50 mg is the standard starting dose for most men. The final and right dosage is determined by your doctor based on safety and response. It is important to take a maximum of one Viagra dose per day.

The medication may start working within 30 minutes to 1 hour after consumption. Even though the drug can stay in the system for up to 24 hours, the main effects typically last for about 4-6 hours. Some men may experience multiple erections during this time. The half-life of Viagra (Sildenafil) is 3 to 5 hours, meaning it will take roughly 4 hours for half of the dose to be eliminated by the body.
