Prescription-strength sildenafil citrate, the same active ingredient as Viagra, reviewed and prescribed by U.S.-licensed doctors. Works in 30–60 minutes. Shipped discreetly to your door.
Sildenafil tablets for men are a prescription oral medication used to treat erectile dysfunction (ED). Sildenafil citrate, the active compound and the generic equivalent of brand-name Viagra, works by relaxing blood vessels and increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain a firm erection. At Green Cap, a licensed U.S. physician reviews your health history and, if appropriate, prescribes sildenafil online, with discreet delivery to your home.
Sildenafil is a PDE5 inhibitor, a class of medication that relaxes smooth muscle in blood vessel walls and improves blood flow. It was originally developed in the late 1980s by Pfizer to treat hypertension and chest pain. During clinical trials, researchers discovered its powerful effect on erectile function, leading to FDA approval for erectile dysfunction treatment in 1998 under the brand name Viagra.
Today, sildenafil citrate is available as an FDA-approved generic for Viagra, offering the identical prescription-strength compound at a fraction of the branded cost. It is also approved under the name Revatio for pulmonary arterial hypertension (PAH).
At Green Cap, we provide sildenafil tablets for men through a telehealth platform: a licensed U.S. physician reviews your health assessment, and, if clinically appropriate, issues a prescription that is fulfilled and shipped discreetly to your address.
Sildenafil is prescribed for adult men experiencing erectile dysfunction, the consistent difficulty getting or keeping an erection firm enough for sexual intercourse. ED is a common and medically recognized condition that affects an estimated 30 million men in the United States. It has physiological causes (reduced blood flow, hormonal factors) as well as psychological contributors (stress, anxiety, relationship factors).
Understanding how sildenafil works can help you feel confident in your treatment. Here is a clear, plain-language explanation reviewed by our clinical team.
During sexual stimulation, the body releases nitric oxide in the penile tissue. This triggers production of cyclic GMP (cGMP), a chemical messenger that relaxes smooth muscle. An enzyme called PDE5 breaks down cGMP. Sildenafil blocks PDE5, allowing cGMP levels to remain elevated.
With higher cGMP levels, the smooth muscles in the penile arteries relax and widen. This increases blood flow into the corpora cavernosa, the two chambers that fill with blood to produce an erection.
Increased blood flow creates the pressure needed to achieve and maintain a firm erection during sexual stimulation. Sildenafil does not cause an erection on its own, sexual arousal is still required.
Sildenafil also relaxes pulmonary blood vessels, reducing the workload on the right side of the heart. This makes it useful in pulmonary arterial hypertension (PAH), where it improves exercise capacity and slows disease progression.
Getting a legitimate prescription for sildenafil should be straightforward, private, and medically sound. Here is exactly how Green Cap works, no hidden steps, no surprises.
Answer a short, confidential health questionnaire about your medical history, current medications, and symptoms. This takes roughly 2–3 minutes. There is no charge to complete the assessment.
One of Green Cap's experienced, licensed U.S. physicians reviews your assessment, not an algorithm, not an automated checklist. They may follow up if clarification is needed. Consultations are HIPAA-compliant.
If sildenafil is clinically appropriate for you, the physician issues a prescription. If it is not, they will explain why and may suggest alternatives. Your safety comes first.
Your medication is dispensed by a licensed U.S. pharmacy and shipped in plain, discreet packaging, no product names or medical terms visible on the outside. Choose 1-month, 3-month, or 6-month supply options.
For PAH, sildenafil is typically prescribed at 20 mg three times daily, approximately 4–6 hours apart. This is a distinct clinical use managed separately from ED treatment.
Most men experience the effects of sildenafil for 4 to 6 hours. The medication does not maintain a continuous erection for this entire duration, it simply keeps you responsive to stimulation during that window. Individual results vary based on metabolism, dosage, and overall health.
Sildenafil may be less effective the first time for some men, particularly if taken too soon before activity or after a heavy meal. Contact your Green Cap physician if you do not see the expected results, your dose or timing may need adjustment.
Like all prescription medications, sildenafil can cause side effects. Most are mild and short-lived. Serious side effects are rare but important to understand before starting treatment.
If you experience any of these, stop taking sildenafil and seek medical attention immediately.
Green Cap's physician review process is specifically designed to identify these contraindications before any prescription is issued.
