Complete Safety Profile and Medical Warnings
Critical Drug Interactions You Must Know
The most serious safety concern with Viagra involves dangerous drug interactions. Never take sildenafil if you're using nitrate medications such as glyceryl trinitrate (GTN spray), isosorbide mononitrate, or any nitrate-based heart medication. This combination can cause a sudden, potentially fatal drop in blood pressure. Similarly, riociguat (used for pulmonary hypertension) is contraindicated with Viagra.
Blood pressure medications require careful consideration. Whilst not absolutely contraindicated, alpha-blockers, ACE inhibitors, and other antihypertensives may interact with sildenafil. Your prescriber will assess these interactions during consultation. EverydayMeds' clinical team evaluates all current medications before approving treatment.
Cardiovascular Health Requirements
Erectile dysfunction treatment requires adequate cardiovascular health. Men with severe heart disease, recent heart attack (within 6 months), unstable angina, or recent stroke should not use Viagra. The medication can affect blood pressure and heart rate, particularly during sexual activity which itself places demands on the cardiovascular system.
If you have controlled heart conditions, diabetes, or high blood pressure, treatment may still be possible under medical supervision. Our UK-licensed prescribers assess individual cardiovascular risk factors to determine suitability. This is why over-the-counter options, whilst available, may not be appropriate for everyone.
Recognising Serious Side Effects
Priapism - an erection lasting more than 4 hours - constitutes a medical emergency requiring immediate hospital treatment. Whilst rare, this condition can cause permanent damage if untreated. Other serious but uncommon side effects include sudden vision or hearing loss, chest pain, or severe allergic reactions.
Common side effects include headache, facial flushing, indigestion, and nasal congestion. These are usually mild and temporary. However, if you experience chest pain, dizziness, or nausea during sexual activity, stop immediately and seek medical attention.
Medical Conditions Requiring Caution
Several conditions require careful evaluation before prescribing sildenafil. Severe liver or kidney impairment affects how the body processes the medication, potentially requiring dose adjustments or alternative treatments. Men with bleeding disorders, stomach ulcers, or retinal conditions need specialist assessment.
Peyronie's disease or other anatomical penile abnormalities may increase priapism risk. Previous episodes of prolonged erection, regardless of cause, represent a relative contraindication requiring careful risk-benefit assessment.
Age and Dosage Considerations
Men over 65 may require lower starting doses due to slower medication clearance and increased sensitivity to side effects. The standard 50mg starting dose might be reduced to 25mg initially. Conversely, some men may require the maximum 100mg dose for effectiveness, though this should only be prescribed after trying lower doses.
Never exceed one dose per 24-hour period, regardless of effectiveness. Taking multiple doses doesn't increase effectiveness but significantly raises side effect risks.
Choosing Between Branded and Generic Options
EverydayMeds offers both Viagra (branded) and sildenafil (generic) at checkout. Both contain identical active ingredients and undergo the same safety assessments. The generic alternative provides considerable cost savings without compromising safety or effectiveness. Your choice depends on personal preference and budget considerations, as both options carry identical warnings and precautions.
