Understanding Sildenafil for Erectile Dysfunction
What Are Sildenafil Tablets?
Sildenafil tablets contain the active ingredient sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that helps treat erectile dysfunction. Originally developed by Pfizer as Viagra, sildenafil is now available as both the branded medication and generic versions. EverydayMeds offers both options, allowing patients to choose between branded Viagra or generic sildenafil based on their preferences and budget considerations.
How Sildenafil Works
Sildenafil works by blocking the PDE5 enzyme, which increases blood flow to the penis during sexual arousal. It's important to understand that sildenafil doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective. The medication typically begins working within 30-60 minutes of taking and effects can last 4-6 hours, though this doesn't mean erections last this duration.
Available Dosages and Usage
Sildenafil tablets are available in three strengths: 25mg, 50mg, and 100mg. The typical starting dose is 50mg, taken approximately one hour before sexual activity. Based on effectiveness and tolerability, the dose may be adjusted to 25mg or increased to a maximum of 100mg. Only one tablet should be taken within a 24-hour period. Taking sildenafil with food, particularly fatty meals, may delay the onset of action.
Eligibility and Clinical Assessment
Sildenafil requires a prescription following consultation with a UK-licensed prescriber. The clinical assessment evaluates your medical history, current medications, and cardiovascular health to ensure safe use. Treatment is suitable for adult men aged 18 and over experiencing erectile dysfunction. Women, individuals under 18, and those with certain medical conditions may not be suitable candidates for treatment.
Important Contraindications
Certain individuals should not take sildenafil due to potentially serious health risks. This includes men taking nitrate medications (such as GTN spray), those with severe heart disease, recent heart attack or stroke within six months, severe liver impairment, or very low blood pressure. The medication should also be avoided by those taking riociguat for pulmonary hypertension or individuals with hereditary retinal disorders.
Side Effects and Considerations
Common side effects of sildenafil may include headaches, facial flushing, indigestion, nasal congestion, and dizziness. Most side effects are mild and temporary. Rare but serious side effects include prolonged erections lasting more than four hours (priapism), sudden vision or hearing loss, or severe chest pain. Any concerning symptoms should prompt immediate medical attention.
Drug Interactions
Sildenafil can interact dangerously with certain medications, particularly nitrates and alpha-blockers. It's crucial to inform your prescriber about all current medications, including over-the-counter drugs and supplements. Some medications may require dose adjustments or alternative treatments to be considered.
