Emergency Situations and When to Seek Help
Immediate Emergency (Call 999 or A&E)
Certain situations with sildenafil require immediate emergency medical attention. Priapism, an erection lasting more than 4 hours, is a medical emergency that can cause permanent damage if not treated promptly. Similarly, severe chest pain, difficulty breathing, or signs of heart attack whilst taking sildenafil necessitate immediate emergency care. The BNF emphasises that nitrate medications should never be given to patients who have taken sildenafil within 24 hours due to dangerous blood pressure drops.
Urgent GP Contact Required
Several symptoms warrant contacting your GP immediately or calling NHS 111. Sudden vision loss or changes, particularly in one eye, may indicate non-arteritic anterior ischaemic optic neuropathy (NAION). Sudden hearing loss or ringing in the ears also requires prompt medical assessment. Severe allergic reactions including facial swelling, difficulty swallowing, or widespread rash need urgent attention. EverydayMeds patients can access clinical support through our UK-licensed prescribers for medication-related concerns.
Routine Medical Review
Regular monitoring helps ensure sildenafil remains appropriate for your health status. Contact your prescriber if you experience persistent side effects like headaches, flushing, or indigestion that don't improve. Changes in your medical conditions, new medications, or cardiovascular symptoms require medication review. The BNF recommends periodic assessment of treatment effectiveness and tolerability. EverydayMeds offers both Viagra (branded) and sildenafil (generic) options, with clinical reviews available to optimise your treatment.
Pre-existing Conditions Requiring Caution
Certain medical conditions require careful monitoring when using sildenafil. Cardiovascular disease, including recent heart attack or stroke, may contraindicate sildenafil use. Liver or kidney impairment may require dose adjustments as outlined in the BNF. Men with anatomical penile abnormalities, blood disorders like sickle cell anaemia, or retinal problems need specialist oversight. Always inform healthcare providers about all medications and health conditions before starting sildenafil treatment.
