Understanding How Sildenafil Works in Your Body
The Science Behind Sildenafil
Sildenafil belongs to a class of medications called PDE5 inhibitors (phosphodiesterase type 5 inhibitors). When you become sexually aroused, your body naturally produces nitric oxide, which triggers a chain reaction leading to increased blood flow to the penis. However, an enzyme called PDE5 can break down this process too quickly, preventing adequate blood flow for a firm erection.
Sildenafil works by selectively blocking the PDE5 enzyme, allowing the natural blood flow mechanism to work more effectively. This means sildenafil enhances your body's natural response to sexual stimulation rather than causing an automatic erection. Both generic sildenafil and branded Viagra contain the same active ingredient and work identically in your body.
Common Side Effects You May Experience
Most men taking sildenafil experience mild to moderate side effects that typically resolve within a few hours. The most commonly reported side effects include headaches (affecting up to 16% of users), facial flushing, indigestion, and nasal congestion. These occur because sildenafil can temporarily affect blood vessels throughout your body, not just in the penile area.
Other frequent side effects include dizziness, nausea, and visual disturbances such as a blue tinge to vision or increased light sensitivity. These effects are generally dose-related, meaning they may be less noticeable at lower doses like 25mg compared to the maximum 100mg dose.
Timing and Duration of Effects
Sildenafil typically begins working within 30-60 minutes of taking the tablet on an empty stomach. However, food, particularly fatty meals, can delay absorption and reduce effectiveness. The medication's effects may last 4-6 hours, though this doesn't mean you'll have an erection for this entire period - sexual stimulation is still required throughout.
Taking sildenafil with alcohol can increase the risk of side effects like dizziness and low blood pressure. It's advisable to limit alcohol consumption when using this medication to ensure optimal effectiveness and safety.
When to Seek Medical Attention
While serious side effects are uncommon, certain symptoms require immediate medical attention. If you experience an erection lasting longer than 4 hours (priapism), sudden vision or hearing loss, or severe chest pain, contact emergency services immediately. These rare but serious complications can cause permanent damage if not treated promptly.
Some men may experience allergic reactions, including skin rash, swelling, or difficulty breathing. If you notice these symptoms, stop taking sildenafil and seek medical help. Your prescriber at EverydayMeds can adjust your dose or recommend alternative treatments if you experience troublesome side effects.
Minimising Side Effects
To reduce the likelihood of side effects, always follow your prescribed dosage and avoid taking more than one tablet in 24 hours. Starting with the lowest effective dose (usually 25mg or 50mg) allows your body to adjust to the medication. Staying hydrated and avoiding excessive alcohol can also help minimise unwanted effects.
If you're prescribed sildenafil through EverydayMeds, you can choose between generic sildenafil or branded Viagra at checkout - both options work identically but may differ in cost. Your prescriber will determine the most suitable dose based on your medical history and response to treatment.
