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.
Most men who take Viagra experience mild to moderate side effects that typically resolve within a few hours. The most frequently reported side effects include headaches, facial flushing, indigestion, and nasal congestion. These effects occur because sildenafil, the active ingredient in both Viagra and generic alternatives, affects blood vessels throughout the body, not just in the genital area.
Headaches affect approximately 16% of men taking Viagra and are usually mild to moderate in intensity. Staying well-hydrated before and after taking the medication can help reduce headache severity. Paracetamol or ibuprofen can be safely taken alongside Viagra if needed. Facial flushing, experienced by about 10% of users, typically appears as redness in the face, neck, or chest area. This effect is temporary and usually subsides within 2-3 hours as the medication's effects diminish.
Indigestion or stomach upset occurs in roughly 7% of men taking sildenafil. Taking Viagra with a light meal rather than on an empty stomach or after heavy, fatty foods can help reduce digestive discomfort. Avoiding alcohol consumption when taking the medication may also help minimise stomach irritation. If persistent indigestion occurs, your prescriber may recommend adjusting your dosage.
Some men may experience temporary changes in vision, including increased sensitivity to light or a blue tinge to vision. These effects are usually mild and short-lived. Nasal congestion or a blocked nose affects about 4% of users and typically resolves as the medication's effects wear off. Using a saline nasal spray may provide relief if needed.
Whilst serious side effects are rare, certain symptoms require urgent medical attention. Priapism, an erection lasting more than 4 hours, requires immediate emergency treatment. Sudden vision or hearing loss, though extremely rare, should prompt immediate medical consultation. Chest pain, particularly during sexual activity, requires urgent assessment. If you experience allergic reactions such as difficulty breathing, swelling of the face or throat, or severe skin reactions, seek emergency medical help immediately.
If side effects prove troublesome, your healthcare provider may recommend starting with a lower dose or switching between branded Viagra and generic sildenafil options. EverydayMeds offers both choices, allowing flexibility in your treatment approach. Some men find that side effects diminish with continued use as their body adjusts to the medication. Your prescriber can guide you through dosage adjustments to find the most suitable option for your individual needs.
