Emergency Situations Requiring Immediate Medical Care
Priapism: A Medical Emergency
Priapism is a prolonged erection lasting more than 4 hours without sexual stimulation. This is a serious medical emergency that can cause permanent damage to penile tissue. If you experience an erection lasting over 4 hours after taking Viagra or sildenafil, seek immediate A&E treatment. Do not wait or feel embarrassed - prompt medical intervention is crucial to prevent long-term complications.
Cardiovascular Symptoms
Viagra affects blood circulation, so cardiovascular symptoms require urgent attention. Contact emergency services immediately if you experience chest pain, severe dizziness, fainting, irregular heartbeat, or breathing difficulties after taking Viagra. These symptoms could indicate dangerous blood pressure changes or cardiovascular complications, particularly if you have underlying heart conditions.
Sudden Vision or Hearing Loss
Rare cases of sudden vision loss (NAION) or hearing loss have been reported with PDE5 inhibitors like sildenafil. If you experience sudden vision changes, eye pain, or hearing loss, stop taking the medication immediately and seek urgent medical attention. These symptoms require prompt evaluation by medical professionals.
Severe Allergic Reactions
Although uncommon, some men may experience allergic reactions to Viagra or sildenafil. Signs include facial swelling, difficulty breathing, severe rash, or throat tightness. These symptoms constitute a medical emergency requiring immediate A&E treatment. Call 999 if you experience breathing difficulties or severe swelling.
Non-Emergency Medical Concerns
For less urgent issues like persistent headaches, nausea, or mild side effects, contact your GP or call NHS 111 for guidance. If Viagra isn't working effectively after several attempts, this isn't an emergency but warrants consultation with your prescriber. EverydayMeds patients can access ongoing support through our clinical team for treatment adjustments.
Drug Interactions and Safety
Never combine Viagra with nitrates (GTN spray, heart medications) as this can cause dangerous blood pressure drops requiring emergency treatment. Always inform emergency medical staff that you've taken Viagra or sildenafil, including the dose and timing. This information is crucial for safe emergency treatment decisions.
