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.

Finasteride 1mg for Hair Loss: quick facts

Finasteride 1mg is a prescription medicine used for male pattern hair loss (androgenetic alopecia). It works by reducing DHT, a hormone involved in hair follicle miniaturisation. Results, if they occur, usually take several months of consistent use.

How long does it take to work?
Many people assess progress at around 3 to 6 months, with a fuller effect often closer to 12 months.
Common considerations
Possible side effects can include reduced libido, erectile dysfunction, low mood, and breast tenderness. These are uncommon and often improve after stopping.
PSA blood test and finasteride
Finasteride can lower PSA levels. If PSA testing is relevant now or in future, results may need cautious interpretation. A baseline PSA is not essential for most younger men using finasteride for hair loss, but can be reasonable if already planned.
