Tamsulosin 400 micrograms (mcg) is a commonly prescribed medication in Australia, mainly used to treat urinary symptoms caused by benign prostatic hyperplasia (BPH), which is an enlargement of the prostate gland that affects many men as they age. This blog post provides a clear, human-friendly guide to tamsulosin 400 mcg, including its dosage, how to take it, and important considerations for Australian patients.
What is Tamsulosin 400 mcg?
Tamsulosin belongs to a group of medicines called alpha-1 blockers. It works by relaxing the muscles in the prostate and bladder neck, making it easier to urinate and relieving symptoms such as difficulty starting urination, weak urine flow, and frequent urination.
The 400 mcg dose refers to the amount of tamsulosin hydrochloride in each modified-release tablet, designed to release the medicine slowly over time for consistent symptom control.
How is Tamsulosin 400 mcg Taken?
- Dosage: The standard dose for adults with BPH in Australia is one 400 mcg tablet once daily.
- Timing: It is recommended to take the tablet about 30 minutes after the same meal each day, usually after breakfast. Taking it with food helps improve absorption and reduces the chance of side effects like dizziness.
- Administration: Swallow the tablet whole with a full glass of water. Do not crush, chew, or break the tablet, as it has a special coating to ensure slow release of the medication.
- Duration: Tamsulosin is often taken long-term to manage symptoms effectively.
What if the Dose Needs to Change?
If after 2 to 4 weeks of treatment the symptoms have not improved sufficiently, your doctor may consider increasing the dose to 800 mcg (two tablets of 400 mcg or a higher strength if available). However, any dose changes should only be made under medical supervision.
If treatment is stopped for several days, it is usually recommended to restart at the 400 mcg dose.
Who Should Avoid Tamsulosin 400 mcg?
- People with severe liver problems or severe kidney impairment should not take tamsulosin 400 mcg tablets.
- Always inform your doctor about other medications you are taking, as some may interact with tamsulosin.
Common Side Effects
Some people may experience side effects such as dizziness, headache, or nasal congestion. These are usually mild and tend to improve over time. If you experience severe dizziness, fainting, or allergic reactions, seek medical advice immediately.

Summary

Taking the tablet after the same meal daily, swallowing it whole, and following your doctor’s instructions will help ensure the medication works effectively and safely.
