Essential Patient Information About Viagra Tablets
Understanding Viagra Tablet Basics
Viagra tablets contain sildenafil citrate as the active ingredient, manufactured by Pfizer as the original branded treatment for erectile dysfunction. The medication works by blocking the PDE5 enzyme, which increases blood flow to the penis during sexual arousal. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.
EverydayMeds offers both branded Viagra and generic sildenafil tablets, giving patients the choice between the original formulation and a more cost-effective alternative with identical active ingredients. Both options require a prescription following consultation with our UK-licensed prescribers.
Dosage and Administration Questions
Viagra tablets are available in three strengths: 25mg, 50mg, and 100mg. Most patients start with the 50mg dose, taken approximately 30-60 minutes before sexual activity. The dosage may be adjusted based on effectiveness and tolerability, with a maximum of one tablet per 24-hour period. The effects typically last 4-6 hours, though this refers to the medication's presence in your system rather than continuous erection duration.
For optimal effectiveness, consider taking Viagra on an empty stomach or after a light meal, as high-fat foods can delay the onset of action. The medication begins working within 30-60 minutes for most patients, though individual response times may vary.
Safety Considerations and Contraindications
Certain medical conditions and medications make Viagra unsuitable for some patients. Never take Viagra if you're using nitrate medications such as glyceryl trinitrate (GTN) spray or isosorbide tablets, as this combination can cause dangerous blood pressure drops. Patients with severe heart disease, recent heart attack or stroke, severe liver problems, or very low blood pressure should not use this medication.
Common drug interactions include alpha-blockers for prostate problems, certain HIV medications, antifungals, and specific antibiotics. Always inform your prescriber about all medications and supplements you're taking during your consultation.
Managing Side Effects and Expectations
Headaches are the most common side effect, affecting more than 1 in 10 users. Other frequent side effects include facial flushing, indigestion, nasal congestion, dizziness, and temporary visual changes such as a blue tinge to vision or light sensitivity. Most side effects are mild and temporary, often diminishing with continued use.
Seek immediate medical attention for serious side effects including priapism (painful erection lasting over 4 hours), sudden vision or hearing loss, chest pain during sexual activity, or signs of severe allergic reaction. These situations require urgent medical intervention.
Lifestyle Factors and Practical Advice
Moderate alcohol consumption is generally acceptable with Viagra, but excessive drinking can reduce effectiveness and worsen side effects like dizziness. Both alcohol and sildenafil can lower blood pressure, so moderation is advisable. Avoid grapefruit and grapefruit juice, which can increase sildenafil levels in your bloodstream.
Lifestyle factors significantly impact erectile dysfunction treatment success. Smoking reduces blood flow throughout the body, including to the penis, so quitting can improve both medication effectiveness and overall sexual health. Regular exercise, maintaining a healthy weight, managing stress, and addressing underlying health conditions like diabetes can all support better treatment outcomes.
