Erectile Dysfunction (ED) Medicines

Erectile dysfunction medicines improve blood flow to the penis and are commonly used when there is difficulty achieving or maintaining an erection.

Common examples include:

  • sildenafil
  • tadalafil
  • vardenafil

These medicines belong to a class called phosphodiesterase type 5 (PDE5) inhibitors.

Important considerations

ED can sometimes be an early marker of:

  • cardiovascular disease
  • diabetes
  • hypertension
  • hormonal imbalance

Assessment should include cardiovascular risk review before prescribing.

These medicines are not suitable for individuals taking nitrates or certain heart medications.

💡 Why proper assessment matters

While some medicines are available through online pharmacies, proper GP assessment ensures:

  • Underlying health conditions aren’t missed
  • Drug interactions are identified
  • Cardiovascular risk is appropriately managed
  • Dosing is optimized for individual needs
  • Side effects are monitored over time

This is particularly important for ED medicines, where symptoms may signal undiagnosed diabetes or heart disease.

Prostate and Urinary Medicines

Men may experience lower urinary tract symptoms (LUTS), including:

  • weak stream
  • urinary frequency
  • urgency
  • nocturia

Common medicines include:

Examples: tamsulosin, alfuzosin
These relax the muscles around the prostate and bladder neck.

Examples: finasteride, dutasteride
These reduce prostate size over time by affecting hormone pathways.

Monitoring and review are important to ensure symptoms improve and to assess PSA testing where appropriate.

Testosterone and Hormonal Medicines

Testosterone deficiency should only be diagnosed with:

  • consistent symptoms
  • confirmed low blood levels on appropriate testing

Testosterone therapy is usually specialist-led and requires monitoring.

Inappropriate testosterone use can carry risks including:

  • cardiovascular complications
  • infertility
  • mood changes

Thorough assessment is essential before considering treatment.

Hair Loss Medicines

Androgenetic alopecia (male pattern hair loss) may be managed with medicines such as:

  • finasteride
  • topical treatments

Finasteride affects hormone pathways and may have side effects including changes in libido or mood in some individuals.

Discussion of risks and benefits is important.

Medicines for Premature Ejaculation

Certain medicines may be used to help delay ejaculation, often off-label in primary care.

Treatment is individualised and may involve psychological and behavioural approaches alongside medication.

Monitoring and Safety

Men’s health medicines may require:

Because some symptoms overlap with cardiovascular disease or endocrine disorders, review should not be purely symptom-based.
