Tamsulosin comes as slow-release tablets and capsules (also called modified release, prolonged release, MR or XL).
The usual dose of tamsulosin for enlarged prostate and kidney stones is 400 micrograms, once a day. The word microgram is sometimes written with the Greek symbol μ followed by the letter g (μg). A microgram is 1,000 times smaller than a milligram (mg).
Tamsulosin, sold under the brand name Flomax, is a commonly prescribed medication used to treat benign prostatic hyperplasia (BPH) It helps relax muscles in the prostate and bladder neck to improve urine flow and reduce BPH symptoms like frequent urination, incomplete bladder emptying, and weak stream While effective, some people wish to stop taking tamsulosin for various reasons. However, stopping tamsulosin suddenly or “cold turkey” can be dangerous.
What Happens When You Stop Tamsulosin Cold Turkey?
Tamsulosin belongs to a class of drugs called alpha-blockers that work by relaxing muscles around the bladder and prostate. When you stop taking it abruptly, those muscles can tighten up again fast, causing BPH symptoms to return quickly Side effects of stopping tamsulosin cold turkey can include
- Increased urinary frequency and urgency
- Trouble emptying the bladder fully
- Weak urine stream
- Dribbling after urination
- Straining to urinate
- Feeling like the bladder isn’t empty after peeing
These effects may appear within days or weeks of your last dose. Symptoms are often worse than they were before starting the medication. The rapid return of BPH symptoms increases your risk for complications like urinary tract infections, bladder damage, and kidney problems.
In addition to worsening BPH symptoms, suddenly stopping tamsulosin can also cause:
- A rapid drop in blood pressure leading to dizziness, fainting, or falls
- Severe headaches
- Irregular heartbeat
- Shortness of breath
- Anxiety
- Insomnia
- Fatigue
These cardiovascular and central nervous system effects occur because your body has become dependent on tamsulosin. Abruptly removing the medication shocks your system.
Is It Dangerous to Stop Tamsulosin Cold Turkey?
Yes, there are risks associated with suddenly stopping tamsulosin instead of tapering off slowly under medical supervision. Potential dangers include:
-
Acute urinary retention: This is a medical emergency where you cannot urinate at all, causing immense pain. It requires immediate treatment, often with a catheter to drain urine from the bladder.
-
Urinary tract infection: BPH makes it easier for bacteria to infect the urinary tract. Stopping tamsulosin raises UTI risk further. UTIs can spread to the kidneys and become life-threatening.
-
Bladder stones: Incomplete bladder emptying and urinary stasis from BPH creates an environment where bladder stones can form. Abrupt tamsulosin withdrawal raises this risk.
-
Kidney dysfunction: Untreated BPH can cause back pressure on the kidneys impairing their function. Suddenly stopping medication puts kidneys at greater risk.
-
Falls or injuries: The dizziness and fainting caused by rapidly stopping tamsulosin increases your chance of falls and associated injuries, especially in older men.
-
Heart problems: Spikes in blood pressure, irregular heart rhythms, and reduced blood flow caused by sudden withdrawal can endanger your heart health.
Clearly, the odds of developing serious complications are much higher if you stop taking tamsulosin cold turkey instead of with careful medical supervision.
How Should You Stop Taking Tamsulosin?
Because abruptly quitting tamsulosin can make symptoms rebound severely, it should never be stopped suddenly without direction from your healthcare provider. Here are some tips for safely discontinuing tamsulosin:
-
Consult your doctor about slowly tapering off the medication over weeks to months. This gives your body time to adjust to less of the drug.
-
Gradually reduce your dose under medical guidance, for example decreasing from 0.8 mg daily to 0.4 mg daily.
-
Schedule frequent checkups as you taper your dose to monitor for return of symptoms or medication side effects.
-
Be prepared to go back to a higher dose if symptoms worsen too much during the taper.
-
Consider switching to another BPH medication with fewer side effects before stopping tamsulosin completely.
-
Keep taking tamsulosin if it’s effectively managing your symptoms and you can tolerate the side effects. Don’t fix what isn’t broken.
-
Seek prompt medical attention if you experience any concerning symptoms like inability to pee, dizziness, chest pain, etc.
By slowly lowering your dosage, your doctor can help avoid complications from tamsulosin withdrawal. Never attempt to stop taking it on your own without guidance.
Why Might You Want to Stop Taking Tamsulosin?
There are a few reasons why someone might wish to stop using tamsulosin under medical supervision, including:
- Bothersome side effects like dizziness, headaches, or abnormal ejaculation
- Planning for cataract surgery – tamsulosin can cause complications
- Interactions with other medications you are prescribed
- BPH symptoms are well-controlled so medication no longer needed

- Concerns about long-term use of medication as you age
- Developed a medical condition where tamsulosin is unsafe like kidney disease
Whatever your reason for wanting to stop tamsulosin, always talk to your doctor first to create a discontinuation plan that is safe.
What are Alternatives if You Can’t Tolerate Tamsulosin?
For men who struggle with tamsulosin side effects or find it ineffective, other BPH treatment options include:
-
Alpha-blockers: Doxazosin, terazosin, alfuzosin, and silodosin work similarly but may cause fewer side effects.
-
5-alpha reductase inhibitors: Finasteride and dutasteride shrink the prostate itself.
-
Combination therapy: An alpha-blocker plus 5-ARI together.
-
PDE5 inhibitors: Like tadalafil, improve urine flow and BPH symptoms.
-
Phytotherapy: Saw palmetto and beta-sitosterol supplements help some men.
-
Minimally invasive procedures: Transurethral microwave thermotherapy, prostate stents, or UroLift.
-
Major surgery: Transurethral resection of the prostate (TURP) or laser procedures.
Be sure to explore alternatives under your doctor’s care rather than stopping medication abruptly.
While tamsulosin can effectively treat BPH, stopping it suddenly instead of gradually can lead to worsening symptoms, complications, and health risks. Always talk to your healthcare provider about safely discontinuing tamsulosin through dose tapering if you wish to stop taking it. With close medical supervision, you can more safely withdrawn from tamsulosin therapy.
If you forget to take it
If you miss a dose of tamsulosin, and you remember on the same day, take the missed dose as soon as you remember. If you do not remember until the next day, skip the missed dose and take your next dose at the usual time.
Do not take 2 doses to make up for a forgotten dose.
If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
