Understanding Viagra and Sildenafil Treatment Options
What is Viagra and How Does It Work?
Viagra is the brand name for sildenafil citrate, originally developed by Pfizer. This prescription medicine belongs to a class of drugs called PDE5 inhibitors, which work by blocking the phosphodiesterase type 5 enzyme. When sexually aroused, this action helps increase blood flow to the penis, making it easier to achieve and maintain an erection. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.
Branded Viagra vs Generic Sildenafil
At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Both medications contain the same active ingredient and work identically, with the main difference being cost. Generic sildenafil offers a more affordable alternative whilst maintaining the same clinical effectiveness. The choice often comes down to personal preference and budget considerations, with many patients opting for the generic version due to significant cost savings.
Available Dosages and Usage Guidelines
Sildenafil is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can be adjusted up to 100mg or down to 25mg based on effectiveness and tolerability. The medication should be taken 30-60 minutes before sexual activity, with effects typically lasting 4-6 hours. However, this doesn't mean an erection lasts this entire duration - it simply means the medication remains active in your system. Only one dose should be taken within a 24-hour period, and fatty meals may delay the onset of action.
Who Can Use Viagra or Sildenafil?
These medications are suitable for adult men over 18 experiencing erectile dysfunction. All patients must complete a thorough clinical assessment with a UK-licensed prescriber before treatment can be dispensed. This assessment evaluates cardiovascular health, current medications, and medical history to ensure safe prescribing. The consultation process at EverydayMeds is confidential and designed to determine the most appropriate treatment approach for each individual.
Important Safety Considerations
Certain individuals should not use sildenafil-based treatments. This includes men taking nitrate medications such as GTN spray or isosorbide tablets, as this combination can cause a dangerous drop in blood pressure. Other contraindications include severe heart disease, recent heart attack or stroke within six months, severe liver problems, and very low blood pressure. Men taking riociguat for pulmonary hypertension should also avoid this medication.
Managing Side Effects and Expectations
Common side effects may include headache, flushing, indigestion, and nasal congestion. These are usually mild and temporary. More serious but rare side effects include sudden vision or hearing loss, or an erection lasting longer than four hours, which requires immediate medical attention. Most men tolerate the medication well, and side effects often diminish with continued use. If side effects persist or are bothersome, dosage adjustment may be considered during follow-up consultations.
