Tamsulosin is a simple capsule that treats the symptoms of BPH, like frequent urination or having problems urinating. It can also help to treat an overactive bladder that isn’t caused by BPH.
It’s common for men’s prostates to become larger as they age, and it’s usually harmless. But the prostate being larger can put pressure on the bladder and the urethra, which causes a range of symptoms. These effects are sometimes called lower urinary tract symptoms, or LUTS.
Tamsulosin doesn’t shrink your prostate, but it does ease the muscles around it and in your bladder. This gives you greater control of your symptoms so you can live life freely again.
How does Tamsulosin work?
Tamsulosin is a type of medication called an alpha 1 blocker. It targets the alpha 1 receptors in your prostate and the neck of your bladder, stopping them from working in the same way. This allows the muscles to relax.[1]
This makes it easier to urinate and to empty your bladder completely when you do. This helps reduce your urgency and makes it easier to start. So Tamsulosin can help ease your symptoms of urinary problems whether they’re caused by BPH or not.
What doses of Tamsulosin are there?
Tamsulosin comes as 400mcg capsules, and you’ll usually only take one a day. A higher dose of Tamsulosin isn’t usually recommended, because it’s a powerful medication. So if 400mcg isn’t enough to control your symptoms, go back and talk to your healthcare provider. There might be another treatment that suits you better.
Lifestyle changes can also help your treatment to work better. Avoiding caffeine, drinking fewer fluids in the evening and making sure your bladder is empty after you go to the bathroom will all help to reduce the likelihood of you getting symptoms.

How to take Tamsulosin
Here are some general directions on how to take Tamsulosin. But you should listen to your doctor’s advice on how exactly to take it.
Swallow Tamsulosin whole with water. Don’t crush, chew or open the capsule.
If you can, take Tamsulosin in the morning. You can still take it at night if that’s easier, just make sure to take it at the same time every day.
The best time to take Tamsulosin is about half an hour after a meal, so it absorbs properly. So taking it a little while after breakfast would be ideal.
It is often easier to swallow Tamsulosin if you take it while sitting or standing. This stops the capsule from getting stuck in your throat.
How long does Tamsulosin take to work?
Unlike a lot of other treatments for BPH (such as 5-alpha reductase inhibitors like finasteride or dutasteride) Tamsulosin starts working very soon after you first take it. While 5-alpha reductase inhibitors can take months to work, Tamsulosin’s effects start to show after a few hours.
It can take longer for your symptoms to completely disappear, with some people not seeing the full benefits of Tamsulosin for a few weeks. So even if you think it’s not working, it’s worth sticking with the treatment and giving your symptoms time to improve.
What should I do if I make a mistake while taking Tamsulosin?
Try to remember to take Tamsulosin at around the same time every day. You can try setting alarms or using a medication app so you don’t forget. Making Tamsulosin a part of your routine might also help, by always taking it at breakfast.
If you forget to take Tamsulosin, take the pill as soon as you remember. If it’s already nearly time for your next pill, you should skip the missed pill. Don’t take double your dosage of Tamsulosin because you missed a pill.
Don’t take too much Tamsulosin at one time. If you do, your blood pressure could become too low and you should get medical attention. Tamsulosin can sometimes make people feel dizzy, especially when they first start taking it. If you feel unsteady or faint after taking Tamsulosin, don’t drive.

Tamsulosin: FAQ
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
How is Tamsulosin different from other treatments for BPH and overactive bladder?
Answer:
There are a few other alpha 1 blockers used for BPH, like Terazosin and Doxazosin. But unlike these drugs, Tamsulosin is less likely to affect your blood pressure and other aspects of your health. It’s also generally considered to cause fewer side effects.[1]
This is because Tamsulosin is more selective about the alpha receptors that it targets. So it’s a good option if you don’t want to experience any changes in your blood pressure, or if you already have low blood pressure.[2]
Is Tamsulosin similar to any other treatments?
Answer:
Tamsulosin is sometimes combined with dutasteride, which is occasionally referred to by the brand names Combodart or Dutrozen. Both of these medications work together to reduce the symptoms of BPH. This is also the case for Vesomni, which is a mixture of Tamsulosin and solifenacin.
Tamsulosin is also sometimes referred to by different brand names. Contiflo, Pamsvax and Faramsil are just some examples of the branded versions. These drugs all have the same active ingredient in the same dose, so they should work in almost the same way. You can choose which one you want to use, although the generic version is often cheaper.
There’s another alpha 1 blocker approved by the FDA for BPH, called alfusozin. According to the American Urological Association Guidelines Committee, alfusozin is similarly effective to tamsulosin, but could come with fewer side effects.[3] So it might be a good option for you if you’ve tried tamsulosin, but had to stop because of side effects.
How effective is Tamsulosin?
Answer:
Tamsulosin is a powerful treatment for lower urinary tract symptoms, BPH-related or not. In one study on men with an overactive bladder, Tamsulosin significantly lowered rates of urinary urgency, nighttime urination and frequency. These effects were apparent after just a four-week trial.[4]
Tamsulosin has also been proven effective in treating BPH symptoms long term. A study into the effects of Tamsulosin over six years of treatment showed that it consistently reduced symptoms, with 71.6%–80.7% of people showing improvement.[2] Since BPH often gets worse over time, taking Tamsulosin could help change the course of your life.
Can I take Tamsulosin and drink alcohol?
Answer:
It’s best to avoid alcohol while you’re taking Tamsulosin. It raises your risk of some side effects, like feeling faint or dizzy. Because they can both lower your blood pressure, the risks are higher with alcohol and Tamsulosin combined.
Alcohol may also make your BPH or overactive bladder symptoms worse. Alcohol is a diuretic. So it makes you urinate a lot, by stopping your body from making as much of a hormone called vasopressin. It’s also a liquid, so it can overload your bladder in two ways. So drinking alcohol can make your treatment less effective.
Do I need a prescription for Tamsulosin?
Answer:
You’ll need a prescription from a clinician to get Tamsulosin. It’s a drug with strong effects, so you shouldn’t take it without a good reason. It’s only meant for people with BPH or an overactive bladder.
