About Tamsulosin Hydrochloride
Indications of Tamsulosin Hydrochloride
Tamsulosin Hydrochloride is indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH) in adult men, such as difficulty urinating, weak urinary stream, urinary frequency, urgency, and incomplete bladder emptying.
- FDA-approved / established use: Relief of functional (dynamic) obstructive symptoms of BPH by relaxing smooth muscle in the bladder neck and prostate.
- Adjunct / combination use: Used together with a 5-alpha-reductase inhibitor (e.g. dutasteride or finasteride) in men with an enlarged prostate for more comprehensive symptom control and reduction in risk of BPH progression.
- Off-label use: Sometimes used off-label to facilitate passage of ureteral (kidney) stones as "medical expulsive therapy," though this is not an FDA-approved indication.
Tamsulosin Hydrochloride is not indicated for the treatment of hypertension and is not indicated for use in women or children, as BPH is a condition specific to the male prostate gland.

Frequently Asked Questions about Tamsulosin Hydrochloride
What is Tamsulosin Hydrochloride used for?
Tamsulosin Hydrochloride is used to relieve urinary symptoms caused by an enlarged prostate (benign prostatic hyperplasia, or BPH) in men, such as difficulty starting urination, weak stream, and frequent urination. It is not used to treat high blood pressure and is not for use in women or children.
How should I take Tamsulosin Hydrochloride?
Take Tamsulosin Hydrochloride once daily, about 30 minutes after the same meal every day, and swallow the capsule whole with water. Do not crush, chew, or open the capsule, as this can affect how the medicine is released and increase side effects.
Why do I feel dizzy after starting Tamsulosin Hydrochloride?
Tamsulosin Hydrochloride can lower blood pressure, especially when standing up, which may cause dizziness, lightheadedness, or fainting, particularly after the first dose or a dose increase. Sit or lie down if you feel dizzy, and avoid driving or hazardous activities until you know how the medicine affects you.
Can I take Tamsulosin Hydrochloride if I am scheduled for cataract surgery?
You must tell your ophthalmologist that you are taking or have previously taken Tamsulosin Hydrochloride before any cataract or glaucoma surgery. It can cause a condition called intraoperative floppy iris syndrome (IFIS), which may require your surgeon to adjust their technique.
Can women or children take Tamsulosin Hydrochloride?
No. Tamsulosin Hydrochloride is indicated only for symptoms of benign prostatic hyperplasia in adult men. It is not indicated for use in women, and safety and efficacy have not been established in children.
What should I do if I miss a dose or stop Tamsulosin Hydrochloride for several days?
If you miss a dose of Tamsulosin Hydrochloride, take it at your next scheduled time; do not double the dose. If therapy has been interrupted for several days, restart at the lower 0.4 mg dose rather than resuming the higher dose, and consult your physician.
