Quick Facts

What It Is and How It Works

Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. Its primary mechanism is to relax blood vessels in particular areas of the body, which enhances blood flow. For erectile dysfunction, this means improved blood flow to the penis, thereby facilitating an erection in response to sexual stimulation. In cases of PAH, it helps relax blood vessels in the lungs to improve blood flow and reduce the workload on the heart.

Indications / Uses

Sildenafil is approved for the treatment of erectile dysfunction and pulmonary arterial hypertension. In erectile dysfunction, it helps men achieve and maintain an erection sufficient for sexual activity. In certain countries, it may be used in lower doses for PAH. Use for any other conditions should be under the guidance of a healthcare provider and may involve off-label applications.

Dosage Forms and Typical Dosing Considerations

Sildenafil is available in various dosages, typically ranging from 20mg to 100mg. The 200mg dosage is not standard and should not be used unless explicitly prescribed by a healthcare provider after careful assessment of individual health needs. The usual starting dose for erectile dysfunction is 50mg, which can be adjusted based on efficacy and tolerability. In PAH, the usual adult dose is 20 mg three times a day. Dosing adjustments may be required for individuals with kidney or liver impairments, as well as considerations for the elderly or those on interacting medications.

How to Take It Correctly Step-by-Step

For the best effect, sildenafil should be taken approximately 30 minutes to 1 hour before planned sexual activity, though it can be taken 4 hours prior. It should be swallowed whole with a glass of water and can be taken with or without food. Avoid high-fat meals as they can delay the medication\’s onset of action. If a dose is missed for PAH, take it as soon as possible unless it’s close to the time for the next dose; do not double up on doses. Store at room temperature, away from moisture and heat.

Side Effects Common to Serious

Common Side Effects

These include headaches, flushing, upset stomach, and nasal congestion. Generally, these symptoms are mild and temporary.

Less Common Side Effects

Some might experience dizziness, back pain, or changes in vision, such as blurred vision or changes in color perception.

Serious or Rare Side Effects

Immediately contact a healthcare provider if experiences occur like chest pain, shortness of breath, fainting, or a prolonged erection lasting more than 4 hours (priapism). Sudden vision or hearing loss needs emergency medical attention.

Contraindications & Precautions

Sildenafil should not be used by individuals who are taking nitrates for chest pain, have severe cardiovascular conditions, or have a known hypersensitivity to the medication. Caution is advised for those with liver or kidney disease, a history of stroke or heart attack, retinitis pigmentosa, or are on medications such as protease inhibitors.

Drug, Food, and Supplement Interactions

Significant interactions include those with nitrates, certain blood pressure medications, and alpha-blockers, as they can lead to dangerous drops in blood pressure. Additionally, grapefruit juice can increase plasma levels of sildenafil, increasing the risk of side effects. It is essential to discuss all medications and supplements with a healthcare provider.
