Emergency Warning Signs Requiring Immediate Medical Help
Priapism: A Medical Emergency
The most serious Viagra warning sign is priapism - an erection lasting more than 4 hours. This requires immediate emergency medical attention as it can cause permanent damage to penile tissue. Priapism occurs in less than 1% of men taking sildenafil, but when it happens, prompt treatment is essential to prevent long-term complications.
Cardiovascular Warning Signs
Stop sexual activity and seek immediate medical help if you experience chest pain, dizziness, or nausea during intercourse whilst taking Viagra. These symptoms could indicate serious cardiovascular problems. Men with heart conditions should be particularly vigilant, as sexual activity combined with ED medication increases cardiac demands.
Sudden Vision or Hearing Changes
Rare but serious side effects include sudden vision loss (NAION - non-arteritic anterior ischaemic optic neuropathy) or hearing impairment. These occur in fewer than 1 in 1,000 users but require immediate medical evaluation. Discontinue Viagra and contact emergency services if you experience sudden changes to sight or hearing.
When to Contact Your Prescriber
Consult your prescriber if you experience persistent side effects including severe headaches, prolonged facial flushing, or significant indigestion that interferes with daily activities. Additionally, contact your doctor if Viagra becomes less effective over time or if you develop new medical conditions whilst taking the medication.
Drug Interaction Warning Signs
Never combine Viagra with nitrate medications (GTN spray, isosorbide tablets) as this can cause life-threatening blood pressure drops. Symptoms of dangerous interactions include severe dizziness, fainting, or difficulty breathing. Always inform healthcare providers about all medications you're taking, including over-the-counter remedies.
