Understanding Viagra Treatment Options
What is Viagra and How Does It Work?
Viagra is the brand name for sildenafil citrate, originally developed by Pfizer. It belongs to a class of medications called PDE5 inhibitors, which work by blocking the phosphodiesterase type 5 enzyme. This action increases blood flow to the penis during sexual arousal, helping men achieve and maintain an erection suitable for sexual activity.
It's important to understand that Viagra does not cause automatic erections. Sexual stimulation is still required for the medication to be effective. The treatment typically begins working within 30-60 minutes of taking a tablet, with effects potentially lasting 4-6 hours. However, this doesn't mean an erection will last for this duration.
Branded Viagra vs Generic Sildenafil
At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically. The main differences are price and packaging - generic sildenafil offers a more cost-effective alternative whilst maintaining the same clinical effectiveness as the branded version.
Both options require a prescription following consultation with a UK-licensed prescriber. Viagra Connect, a 50mg over-the-counter version, is also available from pharmacies, though prescription options offer more dosage flexibility.
Available Dosages and Usage Guidelines
Sildenafil is available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately 30-60 minutes before planned sexual activity. Based on effectiveness and tolerability, the dose may be adjusted to 25mg (for those experiencing side effects) or increased to 100mg (if 50mg proves insufficient).
The maximum frequency is one dose per 24-hour period. Food intake, particularly fatty meals, can delay the onset of action, so taking the medication on an empty stomach may improve effectiveness. The medication should be swallowed whole with water.
Eligibility and Clinical Assessment
Viagra treatment is suitable for adult men (18+) experiencing erectile dysfunction. Before prescribing, healthcare providers conduct a comprehensive clinical assessment evaluating cardiovascular health, current medications, and medical history. This assessment ensures the treatment is both safe and appropriate for each individual patient.
The consultation process is crucial for identifying any contraindications or potential drug interactions. Patients with certain medical conditions or those taking specific medications may not be suitable candidates for this treatment.
Important Contraindications and Safety Considerations
Several important contraindications must be considered before starting treatment. Men taking nitrates (such as GTN spray or isosorbide tablets) should never use sildenafil due to the risk of dangerous blood pressure drops. Other contraindications include severe heart disease, recent heart attack or stroke (within six months), severe liver impairment, and very low blood pressure.
Particular caution is required for men with cardiovascular conditions, as sexual activity itself may pose risks. The clinical assessment helps determine whether the cardiovascular system can safely handle the combined effects of the medication and sexual activity.
Potential Side Effects
Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These are generally mild and temporary. Less common but more serious side effects can include sudden vision or hearing loss, prolonged erections lasting more than four hours, and significant drops in blood pressure.
Patients should seek immediate medical attention if they experience chest pain during sexual activity, sudden vision or hearing loss, or erections lasting longer than four hours. Most men tolerate the medication well when used as prescribed.
