When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.
Clinical studies show that most men experience few or no side effects when taking Viagra (sildenafil). The most commonly reported effects include headaches, experienced by approximately 16% of users, facial flushing in around 10% of men, and nasal congestion affecting about 4% of users. These effects typically occur because sildenafil affects blood vessels throughout the body, not just in the genital area.
Viagra works by inhibiting an enzyme called PDE5, which increases blood flow to facilitate erections. However, similar enzymes exist elsewhere in the body, which explains why some men experience effects like headaches or flushing. The intensity of side effects often correlates with dosage strength, which is why doctors typically start patients on 50mg before adjusting if necessary.
Most side effects are temporary and resolve within 2-4 hours as the medication leaves your system. For headaches, staying hydrated and taking paracetamol may help. Facial flushing usually subsides naturally and can be minimised by avoiding alcohol and large meals before taking the medication. If nasal congestion occurs, a saline nasal spray might provide relief.
Whilst serious side effects are uncommon, certain symptoms require immediate medical attention. These include chest pain, severe dizziness, vision changes, or an erection lasting more than four hours (priapism). If you experience any allergic reactions such as difficulty breathing, swelling of the face or throat, seek emergency medical care immediately.
Your likelihood of experiencing side effects may be influenced by several factors. Age can play a role, with men over 65 sometimes more sensitive to sildenafil's effects. Existing health conditions, particularly cardiovascular issues, may increase your risk profile. Additionally, certain medications can interact with Viagra, potentially intensifying side effects or creating dangerous complications.
Both branded Viagra and generic sildenafil contain the same active ingredient and carry identical side effect profiles. The choice between them often comes down to personal preference and cost considerations. Some patients prefer the reassurance of the branded medication, whilst others opt for the cost-effectiveness of the generic version. At EverydayMeds, our clinical team can help you determine which option might be most suitable for your circumstances.
Several strategies may help minimise potential side effects. Taking Viagra on an empty stomach can improve absorption and potentially reduce some effects. Avoiding excessive alcohol consumption is important, as it can increase the risk of side effects and reduce the medication's effectiveness. Starting with the lowest effective dose and only increasing if necessary under medical supervision is also advisable.
It's one of the most common conditions we treat, and one of the most treatable.
