Many older men suffer from Benign Prostatic Hyperplasia or BPH. Your risk of contracting BPH increases with age, and 90% of men aged 85+ have this condition. BPH is characterized by prostate enlargement without cancer. It makes it difficult to urinate as the bladder wall becomes thicker and pinches the urethra. But drugs like Flomax (tamsulosin) help relieve the symptoms of prostate enlargement in older men.
It’s an alpha-1 blocker containing different ingredients, such as talc, gelatin, iron oxide, etc. It’ll relax the smooth muscles in your bladder, making it easier to urinate and empty it. It is also used to treat kidney stones in males.
Precautions and Warnings with Flomax
These are the most crucial precautions for Flomax users. Before getting a Flomax prescription, please tell your doctor if you have any major health conditions. Some major precautions and warnings for Flomax users are:
- Don’t take Flomax if you’re already on a similar drug (check Flomax Alternatives below)
- Avoid standing quickly, and be careful when driving your car.
- Don’t spend too much time in the sun when taking tamsulosin.
- Tell your doctor if you have had a history of prostate cancer or LBP.
- Inform your doctor if you are allergic to sulfa drugs.

It would help if you did not mix grapefruit juice with Flomax as well because grapefruits may affect your hepatic/intestinal enzyme CYP3A4 metabolism.
In general, Flomax is known to interact with these medicines:
- Warfarin

- Cialis
- Ketoconazole

Strengths and Dosages of Flomax
Flomax often comes as a tablet containing 0.4mg of tamsulosin hydrochloride. One part of the pill is brownish in color, while the other is orange. The brownish part includes the name of the drug, “Flomax,” and the dosage emblazoned on the surface. The orange part says “BI 58”.
Your doctor will prescribe you the strength tailored to your unique needs. Usually, males will get a starting dose of 0.4mg. A typical user will take this drug daily for 2 to 4 weeks and, if that doesn’t work, double their daily dose. The second-most commonly starting dose is 0.8mg. A doctor will prescribe you a dose based on your varying symptoms and medical history.
Surveys show that Flomax treats the most common symptoms of BPH in less than a month. It is crucial to be patient and not take extra dosages of tamsulosin without consulting a doctor. This is because overdosing on tamsulosin can lead to these health conditions:
- Flu-like symptoms
- A painful and prolonged erection (priapism)
- Blistering and peeling of skin
- Breathing difficulties and diarrhea
- Low blood pressure coupled with dizziness
Flomax Alternatives
Flomax is available primarily as a name-brand drug. However, you can also buy alpha-blockers other than tamsulosin if they cost less than the branded version. Doctor-approved alternatives to Flomax include:
Flomax FAQ
What is Flomax used for?
Flomax helps men who have an enlarged prostate. It helps them urinate comfortably while also facilitating the easy passage of kidney stones.
How does Flomax work?
It’s an alpha-1 blocker that relaxes the smooth muscles in your bladder and prostate. However, it does not decrease the size of the user’s enlarged prostate and doesn’t work when the enlargement has been caused by some type of cancer.
How long does it take for Flomax to work?
Flomax (tamsulosin) can start working quickly, relaxing the muscles in your prostate and bladder within 48 hours. You might even feel some initial improvement in urine flow during this time. However, it can take up to five days for Flomax to reach its full effectiveness. The most noticeable improvements in urinary symptoms like difficulty starting urination, weak stream, or frequent urination (including at night) typically take 4 to 6 weeks to appear.
What does Flomax do for kidney stones?
Several studies show that tamsulosin helps men pass larger kidney stones. It relaxes the ureter’s smooth muscles and lets kidney stones pass easily within 48 hours of taking Flomax. That’s why it is used as an off-label drug to treat kidney stones.

When should I take Flomax?
You should take Flomax 30 minutes after the same meal daily. For instance, you may take a pill half an hour after breakfast every day. Consistency is important if you want quick healing.
What is the biggest side effect of using Flomax?
Abnormal ejaculation and floppy iris syndrome are the two most significant adverse effects of taking Flomax. Contact your doctor right away if you are suffering from these conditions.
When should I stop taking Flomax?
If you experience any of the adverse symptoms of Flomax, stop taking it immediately and get in touch with your healthcare provider. Avoid taking this drug if you suffer from:
- Dizziness and fainting
- Symptoms of heart attack
- Painful, long-lasting erection
Is there a generic for Flomax?
You can buy tamsulosin oral capsules. Flomax is the brand-name version of tamsulosin. Today, it is the 24th most prescribed drug in the United States.
How long does it take to stop Flomax before cataract surgery?
Doctors recommend that you stop taking tamsulosin 1 to 2 weeks before cataract surgery because you risk developing intraoperative floppy iris syndrome (IFIS) if you are taking Flomax or other drugs before the scheduled surgery. Some sources recommend not taking tamsulosin two months before the surgery.
What if you take too much Flomax?
Overdosing on Flomax can lower your blood pressure. You’ll feel severe dizziness and even faint due to low blood pressure (LBP). You’ll be lightheaded due to a sudden increase in heart rate. If you experience these symptoms after taking Flomax, reach out to a doctor right away.
Can Flomax treat erectile dysfunction?
Some preliminary studies show that Flomax can help men with erectile dysfunction. However, it also leads to abnormal ejaculation, so Flomax or tamsulosin isn’t the right way to treat ED, unlike Viagra or other alternatives.
