Benign prostatic hyperplasia (BPH), commonly called prostate enlargement, is a condition that affects many men as they age. In Singapore, medication is often prescribed to relieve urinary symptoms caused by an enlarged prostate.
However, these medications can come with side effects that may affect energy levels, blood pressure, and sexual health. Understanding what to expect may help you make informed choices together with your doctor.

What Is the Purpose of Enlarged Prostate Medication?
Medications are often recommended for men whose symptoms interfere with daily life. The goal of medication is to relax or shrink the prostate so that urine can flow more easily.
There are two main types of medication used:
- Alpha-blockers – help relax the muscles of the prostate and bladder neck, improving urine flow.
- 5-alpha-reductase inhibitors (5-ARIs) – shrink the prostate over time by reducing the effects of certain male hormones.
In some cases, both types are prescribed together for better results.
Common Enlarged Prostate Medication Side Effects
While these medications can be very effective, they can also cause side effects. Not every man experiences them, and many effects are mild and temporary. Still, being aware of what might happen is important.
1. Alpha-blockers (such as tamsulosin, alfuzosin)
Alpha-blockers work by relaxing the muscles in the prostate and bladder neck to relieve urinary blockage. They are often prescribed first because they start working within days.
Possible side effects:
- Dizziness or light-headedness, especially when standing up suddenly (postural hypotension).
- Nasal congestion and fatigue.
- Retrograde or reduced ejaculation – semen may flow backward into the bladder instead of out of the penis.
- Mild headache.
These side effects are usually mild and may improve after a few weeks or with dose adjustments.
2. 5-alpha-reductase inhibitors (such as finasteride, dutasteride)
These medicines block the conversion of testosterone into dihydrotestosterone (DHT), the hormone responsible for prostate growth. They help to gradually shrink the prostate over months.
Possible side effects:
- Reduced sexual desire (libido).
- Erectile dysfunction.
- Reduced semen volume.
- Breast tenderness or swelling (rare).
- Mood changes (rare but possible).
Some men may experience sexual side effects that persist after stopping the drug, although this is uncommon. Always discuss any symptoms with your doctor before discontinuing treatment.
3. Combination therapy
Doctors may sometimes prescribe both alpha-blockers and 5-ARIs together, especially if the prostate is significantly enlarged. This can provide better symptom relief but may also increase the chance of side effects such as dizziness or sexual issues. Combination therapy should only be used under the supervision of a qualified urologist.
What to Do If You Experience Side Effects
- Do not stop medication abruptly. Always check with your doctor before making changes.
- Monitor symptoms. Note when side effects occur and their severity.
- Discuss alternatives. Some men may benefit from switching to a different drug or dose.
- Consider other treatments. Minimally invasive options or surgical procedures are available in Singapore for those who prefer to avoid long-term medication.

- Evaluate prostate size and urinary flow.
- Explain the risks and benefits of each medication.
- Suggest alternatives if side effects occur.
