Prostate Medication

The 5 Side Effects Of Flomax

Are you taking Flomax or Tamsulosin (tamsulosin hydrochloride), or thinking about taking them or a similar prescription drug for your prostate?

If so, then it is important to be aware of the potential side effects.

Why do Doctors prescribe Flomax?

Flomax (Tamsulosin) belongs to a class of medications known as alpha-adrenergic blockers.

It is used to treat the signs and symptoms of benign prostatic hyperplasia. Doctors prescribe Flomax more often than any other drug for the prostate.

However, here lies the problem. Flomax tricks you into thinking its working, and you think you are getting better because the symptoms of BPH are getting a little better.

But the truth is that those improvements won’t last… they are not even real. Flomax cannot shrink your prostate and does nothing to alleviate or cure the underlying condition.

All it ever does is HIDE your symptoms… and let the disease get worse and worse until you cannot hide from it anymore.

Why should that matter to you? Before we answer that question, we need to explain how Flomax works.

How does Flomax help?

You have “sphincter muscles” in your urethra. Sphincter muscles enable you to hold in your urine until you can get to a toilet.

What Flomax does is paralyze your sphincter muscles in a permanently relaxed state… it has no effect on your prostate health whatsoever.

The result in half of the men who take Flomax is that it becomes immediately easier to pee and to empty their bladder.

You may experience short-term relief of urinary symptoms, but it only works in about half of the men who take it. So, it isn’t really a very effective treatment.

Flomax is not doing anything at all to deal with the source of your problem, which is your enlarged prostate.

Because it’s not actually doing anything for your prostate, as time goes by, your prostate will continue to enlarge and eventually simply relaxing your sphincter muscles are not going to help you.

The plumber analogy…

Here’s a good analogy. Imagine you have plumbing, which is all clogged up inside.

That slows the passage of water. To solve the problem, you open the valve more that allows for more water to pass – instant solution – but the pipe continues to clog.

Eventually, the wide-open valve can no longer help. You might think that’s okay it helps now, and when it no longer helps, I’ll do or take something else… Unfortunately, it’s not that simple.

You see, if you go back to the source of the problem, which is an enlarged and probably inflamed prostate, it’s not a good idea to ignore that.

Inflammation is potentially the beginning of cancer, so if you have inflammation, you want to deal with it. Not ignore it.

A symptom is a warning sign.

If you allow Flomax to hide the symptoms, you may believe the problem has gone away, but it hasn’t.

Your prostate will continue getting a lot worse without any warning until one day; it’s too late.

Many men choose to avoid Flomax all together because of the side effects.

There are some side effects of Flomax that are incredibly common but are rarely talked about.

Mainly because men don’t realize that Flomax causes them.

They think they are just everyday ailments or even just normal aches and pains associated with getting older or being less than healthy.

Because these are all things that men might mistakenly think are caused by their advancing age, Flomax is causing their discomfort.

They just grit their teeth and think these flu and cold-like symptoms are just the new normal.

The 5 side effects of Flomax

1) The side-effects that ruin your sex life

The side effect that men hate most is loss of libido and even erectile dysfunction.

Flomax side effects can diminish your desire to have sex and even if you managed to work up the desire, taking Flomax means that the result can be an embarrassing failure.

Also, Flomax will often inhibit the production of semen and in some cases, dry, painful, and even retrograde ejaculation.

A Cochrane systematic review looked at the effects of Flomax for BPH in 2003. The analysis involved 14 studies that ranged from 1 to 6 months long.

The study participants described improvements in symptoms. However, they also found 37 adverse side effects, and 63% reported some form of side effect.

2) Cataracts

If you are going to have cataract surgery, then it is essential that you avoid the use of Flomax.

Flomax has been shown to cause complications during cataract surgery and result in floppy eye syndrome.

IFIS is a small pupil syndrome variant that is characterized by a flaccid iris that billows in response to intraoperative irrigation (washing out a wound during surgery) despite preoperative use of mydriatic drugs.

3) Long-term incontinence

There is also a long-term effect of Flomax, which is rarely discussed. When sphincter muscles are continuously relaxed, they are also weakened.

I’m sure you’ve heard the expression: If you don’t use it, you lose it. Over time, your weakened sphincter muscles can predispose you to incontinence.

If you don’t want to risk having to wear adult diapers for the rest of your life, you should consider using a side effect free and safe alternative to Flomax.

4) A dangerous side effect

Perhaps, one of the most dangerous side effects of Flomax is something called syncope.

That’s a fancy medical name for a sudden loss of consciousness. Imagine if that happens when you’re at the top of the stairs or driving a car.

Think of the potential risk you’re putting yourself in, but also other people around you. A further cause for concern is the risk of hypotension, which has rarely been reported in clinical trials.

Alpha-blocker medications, such as tamsulosin, relax the smooth muscles in the heart, which leads to low blood pressure. (Flomax should not be used to treat high blood pressure).

A cohort study involving 147, 084 men that used an alpha-blocker from 2003 to 2013 were compared to an equal number of men who decided against the use of alpha-blocker therapy, to examine whether alpha-blockers increased the risk of falling.

This is because it has been suggested that hypotension can result in dangerous falls, fractures, or head injuries.

The study found that alpha-blockers are associated with a small but significant increase in the risk of hospitalization or emergency room assessment for a fall, and an increase in the risk of fracture by 16% and of head trauma by 15% during the first 90 days of use.

5) An even more important side effect…

A clinical study at the Copenhagen University Hospital Herlev showed that men with BPH have an increased risk of developing and dying from prostate cancer.

Data were examined from five national registries and found that in a total of just over three million Scandinavian men, there were just over 50,000 diagnosed with prostate cancer and 25,000 fatalities due to prostate cancer.

The study also found that over twenty-seven years, BPH was associated with a two to three-fold increased risk of men developing prostate cancer.

Following this, it also found a two to eight-fold increased risk of them dying from prostate cancer when compared to men that did not suffer from BPH.

But you don’t have to risk any of the side effects if you just use a Natural supplement.

Drug interactions

As with any drug, it is essential that you are aware and informed of any potential drug interactions.

Drug interactions and warnings include that Flomax capsules should not be used in combination with other alpha-adrenergic blocking agents.

You should consider any allergic reactions that you may have. If a patient reports a serious, life-threatening sulfa allergy, caution is warranted when administering Flomax capsules.

Always consult your doctor about whether or not it will interact with any medications you are currently taking.

Natural alternatives

Flomax (Tamsulosin) is a synthetic prescription drug. That means that by definition, it has side effects.

And as mentioned earlier, it doesn’t have any effect on your prostate at all. It only affects your sphincter muscles, and that can cause problems down the line.

The main reason why it is so important to cure your prostate rather than just alleviate your symptoms is that it is only a temporary fix.

By ignoring the underlying cause, it can only get worse.

The good news is that you don’t have to rely on ineffective drugs to help you with your prostate problems. Because it’s entirely possible to treat an enlarged prostate and lower your PSA without medication.

You can reduce nighttime waking, improve urinary flow, and fight BPH safely, naturally, and without any nasty side effects.

    • Ben's Natural Health Team

      Hi Eric, we do not recommend stopping Flomax (Tamsulosin) cold turkey. It is never good to stop a drug abruptly, particularly if you have been taking it for some time. It can kick back at you. You should make the changes to your diet and take Total Health with Flomax for one month.

    I’ve had 25 radiation treatments for prostate cancer. My PSA readings are way down (.2), but still getting up 5, 6 times at night. Is there other treatments to deal with this problem?

  4. Mr Leon Menzies Racionzer

    I tried Total Health, Prostate Healer and Prostate Power for approximately 2 years. I wanted to give it a really good run before deciding that it had absolutely no effect on my BPH symptoms. I was taking Tamsulosin and had suffered several times with syncope particularly when flying and what I can only describe as loco-motor ataxia when getting up during the night. Over a period of a year I gradually reduced the dosage and am now down to only one a week which I intend stopping altogether now. This seems to have cured the syncope and the ataxia I was experiencing when I had to get up at night to urinate. As for my BPH symptoms they remain much as they have been for possibly 2 decades. To be fair to these supposedly wonder supplements, I am 83 years old and perhaps they don’t work for people of my age so I am not advising anybody to give up on them but just be careful; the advertising is very clever and psychologically powerful. There is a lot of money in supplements and non less so than Ben Ong’s. As for Tamsulosin I would advise don’t start taking it, it is a long slow process getting off it
