Emergency Warning Signs Requiring Immediate Help

Cardiovascular Emergency Symptoms

Seek immediate medical attention if you experience chest pain, irregular heartbeat, shortness of breath, or severe dizziness whilst taking sildenafil. These symptoms may indicate serious cardiovascular complications requiring urgent assessment. The combination of sildenafil with certain heart conditions or medications can pose significant risks to your health and wellbeing.

Priapism: A Medical Emergency

An erection lasting more than 4 hours constitutes a medical emergency called priapism. This serious condition requires immediate hospital treatment to prevent permanent damage. Contact emergency services or attend A&E immediately if this occurs whilst using sildenafil or any erectile dysfunction medication.

Sudden Vision or Hearing Changes

Sudden loss of vision in one or both eyes, or sudden hearing loss, requires immediate medical evaluation. Although rare, these serious side effects have been reported with PDE5 inhibitors including sildenafil. Stop taking the medication and seek urgent medical care if you experience these symptoms.

When to Contact Your GP About Treatment

Schedule a routine appointment with your doctor if sildenafil becomes less effective, you experience persistent mild side effects, or your health conditions change. Your GP can adjust your dosage, review interactions with new medications, or consider alternative treatments. Regular monitoring ensures your treatment remains appropriate for your evolving health needs.

Pre-Treatment Medical Assessment Requirements

Before starting sildenafil treatment, your doctor must assess your cardiovascular health, current medications, and medical history. This evaluation determines whether sildenafil is safe for you, particularly if you have heart conditions, take nitrate medications, or have other health concerns. EverydayMeds offers both branded Viagra and generic sildenafil options following successful clinical assessment by our UK-registered prescribers.
