Essential Viagra Information for Men
What Is Viagra and How Does It Work for Men?
Viagra is the branded version of sildenafil citrate, a prescription medication specifically designed to help men with erectile dysfunction. It works by blocking the PDE5 enzyme, which increases blood flow to the penis during sexual arousal. Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, both containing the same active ingredient.
What Dosages Are Available for Male Patients?
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, taken approximately 30-60 minutes before sexual activity. Based on effectiveness and tolerability, your prescriber may adjust this to 25mg or increase to 100mg. The maximum dose is one tablet per 24-hour period, regardless of strength.
Taking Viagra on an empty stomach or after a light meal typically provides faster results, as heavy or fatty foods can delay absorption. The effects can last 4-6 hours, though this doesn't mean an erection will persist for this duration.
Who Is Eligible to Take Viagra?
Viagra is suitable for adult men aged 18 and over who experience erectile dysfunction. However, not all men can safely take this medication. You must complete a clinical assessment with a UK-licensed prescriber who will evaluate your cardiovascular health, current medications, and medical history.
Men taking nitrate medications (such as GTN spray for angina), those with severe heart conditions, recent heart attacks or strokes, or severe liver problems cannot take Viagra due to serious health risks. The online consultation process ensures the medication is safe and appropriate for your individual circumstances.
What Are the Most Common Side Effects?
The most frequently reported side effect is headache, experienced by more than 1 in 10 men. Other common side effects include facial flushing, indigestion, nasal congestion, dizziness, and temporary visual changes such as increased light sensitivity or a blue tinge to vision. These effects are typically mild and often reduce as your body adjusts to the medication.
Serious side effects requiring immediate medical attention include painful erections lasting more than 4 hours (priapism), sudden vision or hearing loss, chest pain during sexual activity, or severe allergic reactions. These are rare but require urgent medical care.
Important Drug Interactions and Safety Warnings
Never combine Viagra with nitrate medications or recreational drugs containing nitrates (poppers), as this can cause a dangerous drop in blood pressure. Men taking alpha-blockers for prostate problems should use caution, as combining these with Viagra may also lower blood pressure significantly.
Certain medications can affect how Viagra works, including some HIV treatments, antifungals, and antibiotics. Always inform your prescriber about all medications and supplements you're taking during your consultation.
Alcohol and Lifestyle Considerations
Moderate alcohol consumption is unlikely to cause problems with Viagra, but excessive drinking can reduce effectiveness and worsen side effects like dizziness. Both alcohol and Viagra can lower blood pressure, so limiting alcohol intake on days you plan to use the medication is advisable.
Lifestyle factors significantly impact erectile function. Smoking reduces blood flow and can make Viagra less effective, whilst maintaining a healthy weight, regular exercise, and managing stress can improve overall treatment outcomes.
