ED Care

Erectile Dysfunction (ED): Medicines, Treatment Options and Safety

Erectile dysfunction is difficulty getting or maintaining an erection firm enough for sexual activity. Occasional erection problems can happen, particularly during periods of stress or tiredness. When the problem keeps happening, a medical assessment can help identify the cause and suitable treatment.

​

ED care is not simply about choosing a tablet. It involves understanding physical health, emotional wellbeing, existing medicines and individual treatment needs. An approach that works for one person may not be appropriate for another.

​

Our erectile dysfunction guides provide additional educational information about erection problems and treatment considerations.

​

Common Causes of Erectile Dysfunction

An erection depends on coordinated activity involving blood vessels, nerves, hormones and the brain. Problems affecting any of these can contribute to ED.

​

Possible causes and contributing factors include:

• Diabetes and conditions affecting blood circulation

• High blood pressure and cardiovascular disease

• Low testosterone or other hormonal conditions

• Nerve damage or previous pelvic surgery

• Side effects of certain medicines

• Stress, anxiety or depression

• Smoking, excessive alcohol use and physical inactivity

​

Physical and psychological factors can occur together. The NIH information about ED symptoms and causes explains these connections.

​

Main Erectile Dysfunction Treatment Options

Oral ED Medicines

Sildenafil, tadalafil, vardenafil and avanafil are commonly used oral treatments belonging to a group called PDE5 inhibitors. These medicines support erections by improving blood flow to the penis during sexual stimulation.

​

They differ in their onset, duration, food-related instructions and suitability for individual patients. They do not automatically create sexual desire or permanently resolve every underlying cause of ED.

​

The PDE5 inhibitor medicine category organizes related options. A healthcare professional should confirm the appropriate medicine and strength before treatment begins.

​

Other Medical Treatments

If oral medicines are unsuitable or ineffective, a specialist may discuss a vacuum erection device, prescribed injections or other treatments. Penile implants may be considered in selected cases when other approaches have not helped.

​

Testosterone treatment is not a general solution for erection problems. It may be considered when low testosterone has been confirmed and a clinician determines that treatment is appropriate.

​

The NIH overview of erectile dysfunction treatments explains these options.

​

Medical Assessment Before Starting Treatment

A clinician may ask when erection problems started, how often they occur, whether sexual desire has changed and which medicines or supplements you take. A physical examination and selected tests may help identify contributing conditions.

​

Treatment decisions may also consider:

• Blood pressure and heart health

• Kidney and liver function

• Previous treatment response

• Possible medicine interactions

• Whether sexual activity is medically appropriate

• Your preferences and treatment expectations

​

Not everyone needs the same tests. The NIH guide to diagnosing erectile dysfunction describes how medical history, examination and testing support an individual assessment.

​

Do not stop an existing prescription yourself if you think it is affecting erections.

​

Choosing the Right Dose and Schedule

ED medicines are not interchangeable tablet for tablet. A higher number of milligrams does not automatically mean a medicine is more suitable or will produce better results.

​

Some medicines are used before sexual activity. Tadalafil may be prescribed either as needed or as a daily regimen, with the dose and schedule selected by a clinician. Do not switch between these approaches yourself.

​

Follow the instructions concerning food, timing and frequency. If treatment does not help, speak with the prescriber rather than taking extra tablets or combining medicines.

​

Important Medicine Interactions

PDE5 inhibitors must not be combined with nitrate medicines used for chest pain, nitrate/nitrite “poppers” or riociguat. These combinations can cause a dangerous fall in blood pressure.

​

Alpha-blockers, blood-pressure medicines and certain other treatments may also require additional precautions. Tell your clinician about every prescription, non-prescription medicine, vitamin and supplement you use.

​

Avoid combining different ED medicines unless specifically directed by a qualified specialist. The MedlinePlus tadalafil safety information explains important dosing and interaction precautions.

​

Possible Side Effects and Urgent Warning Signs

Possible side effects include headache, flushing, indigestion, nasal congestion, dizziness or muscle discomfort. The pattern varies between medicines. Report persistent or troublesome symptoms to the prescriber.

​

Seek immediate medical help for:

• An erection lasting longer than four hours

• Sudden loss or marked reduction of vision or hearing

• Chest pain, fainting or severe breathing difficulty

• Swelling of the face or throat

​

If chest pain develops after taking an ED medicine, stop sexual activity and get emergency help. Do not take a nitrate medicine yourself. Tell emergency staff which medicine you took and when.

​

The MedlinePlus sildenafil precautions provide further information about side effects and emergency warning signs.

​

Supporting Long-Term Erectile Health

Regular physical activity, stopping smoking, reducing excessive alcohol use and managing existing health conditions can support erectile health. Counselling or sex therapy may help when stress, anxiety or relationship concerns contribute to the problem.

​

These approaches may complement medical treatment rather than replace it. Follow-up appointments allow the clinician to review effectiveness, side effects and any changes in health.

​

The aim is a treatment plan that addresses your needs and underlying causes—not a guaranteed result from a particular product.
