Erectile dysfunction (ED) is one of the most common health conditions affecting men in Ireland, yet it remains one of the least discussed. If you are experiencing difficulty achieving or maintaining an erection, you are not alone. ED affects approximately 1 in 5 Irish men over the age of 40, and the numbers increase with age.

The good news is that erectile dysfunction is highly treatable. With modern medications like Viagra and Cialis, along with convenient online consultation options, most men can find an effective treatment that works for them. This guide covers everything you need to know about ED treatment in Ireland, from understanding the causes to getting a prescription.

What Causes Erectile Dysfunction?

Erectile dysfunction can result from physical, psychological, or lifestyle factors, and often involves a combination of these. Understanding the underlying cause is essential for effective treatment.

Physical Causes

The most common causes of ED are physical in nature, often related to conditions that affect blood flow or nerve function:

Cardiovascular Disease

Poor blood circulation is the leading physical cause of ED. Conditions like high blood pressure, atherosclerosis (hardening of the arteries), and heart disease can restrict blood flow to the penis, making erections difficult to achieve.

Diabetes

Men with diabetes are 2-3 times more likely to experience ED. High blood sugar levels can damage blood vessels and nerves over time, affecting erectile function.

Hormonal Imbalances

Low testosterone levels, thyroid disorders, and other hormonal conditions can contribute to ED. While testosterone replacement is not a first-line treatment for ED, it may be considered when levels are clinically low.

Neurological Conditions

Conditions affecting the nervous system, such as multiple sclerosis, Parkinson disease, or spinal cord injuries, can interfere with the nerve signals required for erections.

Medications

Certain medications can cause or worsen ED, including some blood pressure medications, antidepressants, antihistamines, and prostate cancer treatments. Never stop taking prescribed medication without consulting your doctor.

Psychological Causes

Mental health plays a significant role in sexual function. Psychological causes are more common in younger men but can affect anyone:

  • Performance anxiety: Worry about sexual performance can create a cycle of ED
  • Stress: Work, financial, or relationship stress can interfere with arousal
  • Depression: Can reduce libido and affect erectile function
  • Relationship issues: Communication problems or unresolved conflicts with a partner

Lifestyle Factors

Your daily habits significantly impact erectile function:

  • Smoking: Damages blood vessels and restricts blood flow. Quitting smoking can improve ED.
  • Excessive alcohol: While small amounts may reduce inhibitions, heavy drinking impairs erectile function
  • Lack of exercise: Sedentary lifestyle contributes to obesity and cardiovascular problems
  • Obesity: Excess weight is linked to diabetes, heart disease, and low testosterone
  • Poor sleep: Sleep disorders like sleep apnoea are associated with ED

ED Medications Available in Ireland

Several effective medications are available in Ireland for treating erectile dysfunction. All work by enhancing blood flow to the penis, but they differ in how quickly they work, how long they last, and their side effect profiles.

Viagra (Sildenafil)

Viagra was the first oral ED medication, approved in 1998, and remains the most recognised brand name worldwide.

How it works: Sildenafil is a PDE5 inhibitor that relaxes blood vessels in the penis, allowing increased blood flow when sexually aroused. It does not cause spontaneous erections; sexual stimulation is required.

Dosing:

  • Available in 25mg, 50mg, and 100mg tablets
  • Starting dose is typically 50mg
  • Take 30-60 minutes before sexual activity
  • Do not take more than once in 24 hours
  • Avoid high-fat meals before taking, as this can delay absorption

Duration: Effects last 4-6 hours, with peak effectiveness around 1-2 hours after taking.

Effectiveness: Works for approximately 70% of men with ED.

Viagra Connect (OTC): Since 2018, Viagra Connect (50mg sildenafil) has been available over the counter from pharmacies in Ireland after a consultation with the pharmacist. This provides a more accessible option for men who prefer not to see a doctor.

Cialis (Tadalafil)

Cialis is often called the weekend pill due to its long-lasting effects.

How it works: Like Viagra, tadalafil is a PDE5 inhibitor that enhances blood flow to the penis. Its longer duration makes it popular for men who prefer spontaneity.

Dosing options:

*As-needed (10mg or 20mg):*

  • Take 30 minutes to 12 hours before sexual activity
  • Starting dose is typically 10mg
  • Can be taken with or without food
  • Do not take more than once in 24 hours

*Daily (2.5mg or 5mg):*

  • Taken at the same time each day
  • Allows for spontaneous sexual activity at any time
  • May take 4-5 days to reach full effectiveness
  • Also prescribed for benign prostatic hyperplasia (BPH) symptoms

Duration: Effects can last up to 36 hours.

Cialis for Men (OTC): Similar to Viagra Connect, Cialis for Men (10mg tadalafil) is now available from pharmacies without a prescription after pharmacist consultation.

Other ED Medications

Levitra (Vardenafil)

  • Works similarly to Viagra
  • Available in 5mg, 10mg, and 20mg doses
  • Takes effect in 25-60 minutes
  • Lasts 4-5 hours
  • May be effective for men who do not respond to sildenafil

Spedra (Avanafil)

  • The newest PDE5 inhibitor
  • Available in 50mg, 100mg, and 200mg doses
  • Works faster than other options (15-30 minutes)
  • Lasts 4-6 hours
  • May have fewer side effects due to higher selectivity

How to Get ED Treatment Online in Ireland

Online consultations have made accessing ED treatment easier and more discreet than ever. Here is how the process works with services like GetYourGP.

Step 1: Complete an Online Consultation

  • Your symptoms and how long you have experienced them
  • Your medical history (heart conditions, blood pressure, diabetes)
  • Current medications (especially nitrates)

An Irish Medical Council (IMC) registered GP reviews your consultation. They will assess:

Step 3: Video Consultation (If Required)

For some cases, the GP may want to speak with you via video call to:

  • Discuss your symptoms in more detail
  • Ask additional questions
  • Explain how to use the medication
  • Address any concerns you may have

Step 4: Prescription Issued

If appropriate, the GP issues an electronic prescription that can be sent to:

  • Your nominated pharmacy for collection
  • A delivery pharmacy (some services offer discreet home delivery)

What Makes Online Consultations Appealing?

  • Confidentiality: No waiting room, no face-to-face discussions in busy GP surgeries
  • Convenience: Complete the consultation anytime, from anywhere
  • Speed: Many services offer same-day prescriptions

Over-the-Counter Options

Since 2018, certain ED medications have been available without prescription in Ireland, making treatment more accessible.

  • You take multiple medications
  • You want to explore daily treatment options
  • OTC options have not worked for you
  • You have questions about the cause of your ED

Safety and Side Effects

PDE5 inhibitors are generally safe and well-tolerated, but like all medications, they can cause side effects.

Common Side Effects

These are usually mild and temporary:

  • Headache (most common, affects 15-20%)
  • Facial flushing (feeling warm or red in the face)
  • Nasal congestion (stuffy nose)
  • Indigestion or upset stomach
  • Dizziness
  • Back pain (more common with tadalafil)
  • Muscle aches (more common with tadalafil)
  • Visual changes (rare, slight blue tinge to vision with sildenafil)

Serious Side Effects (Seek Medical Help)

  • Priapism: An erection lasting more than 4 hours. This is a medical emergency and requires immediate treatment.
  • Sudden vision loss: Stop taking the medication and see a doctor immediately
  • Sudden hearing loss: Stop taking the medication and see a doctor immediately
  • Chest pain during or after sex: Could indicate a heart problem

Important Safety Information

Do NOT take ED medications if you:

  • Take nitrate medications (for angina or heart conditions) - this can cause a dangerous drop in blood pressure
  • Take riociguat (Adempas) for pulmonary hypertension
  • Have severe heart or liver problems
  • Have recently had a stroke or heart attack
  • Have low blood pressure (hypotension)
  • Have certain rare inherited eye diseases (retinitis pigmentosa)

Use with caution if you:

  • Take alpha-blockers for prostate problems or blood pressure
  • Have kidney disease
  • Have a bleeding disorder or active peptic ulcer
  • Have a physical abnormality of the penis

Always provide a complete medical history during your consultation to ensure safe prescribing.

When to See a Doctor in Person

While online consultations are suitable for many men, some situations require an in-person visit:

You Should See a Doctor In Person If:

  • You have chest pain or heart problems: ED can be an early warning sign of cardiovascular disease
  • You have never been diagnosed: First-time ED should ideally be assessed in person
  • You have symptoms of low testosterone: Fatigue, reduced muscle mass, mood changes
  • You notice changes in your penis: Curvature, pain, or lumps
  • ED medications have not worked: May need further investigation
  • You have diabetes that is not well controlled: May need blood tests and management
  • You are experiencing relationship problems: May benefit from counselling referral
  • You are under 40 with persistent ED: May indicate underlying health issues

Tests Your Doctor Might Recommend

  • Blood pressure measurement
  • Blood tests (glucose, cholesterol, testosterone, thyroid function)
  • Cardiovascular assessment
  • Referral to a urologist (in some cases)
