What is the indication for Flomax (Tamsulosin)?

From the Guidelines

Flomax (tamsulosin) is primarily used to treat symptoms of benign prostatic hyperplasia (BPH), also known as an enlarged prostate, by relaxing the muscles in the prostate and bladder neck, making it easier to urinate. The standard dose is typically 0.4 mg taken once daily, about 30 minutes after the same meal each day, and some patients may have their dose increased to 0.8 mg daily if needed 1. Flomax belongs to a class of medications called alpha-blockers, which work by inhibiting the alpha1-adrenergic-mediated contraction of prostatic smooth muscle, resulting in bladder outlet obstruction relief 1. Some key points to consider when using Flomax include:

• Potential side effects such as dizziness, especially when first starting the medication or when standing up quickly, retrograde ejaculation (dry orgasm), headache, and nasal congestion 1
• Importance of taking Flomax consistently and not suddenly stopping it without consulting a healthcare provider
• Primary use for men with BPH, but occasional off-label use to help pass kidney stones or treat urinary retention in women
• Comparison with other alpha-blockers, such as doxazosin, alfuzosin, and terazosin, which have similar clinical effectiveness but slightly different adverse-event profiles 1. It's worth noting that while Flomax is effective in relieving symptoms of BPH, it's not a cure for the condition, and patients should be aware of the potential risks and benefits of long-term use 1.

From the FDA Drug Label

Tamsulosin Hydrochloride Capsules is an alpha 1 adrenoceptor antagonist indicated for treatment of the signs and symptoms of benign prostatic hyperplasia (1) Tamsulosin Hydrochloride Capsules are not indicated for the treatment of hypertension (1)

• It is not indicated for the treatment of hypertension. Note that Flomax is another name for the drug tamsulosin.

From the Research

What is Flomax Used For

• Flomax, also known as tamsulosin, is a medication used to treat the symptoms of benign prostatic hyperplasia (BPH), a condition in which the prostate gland is enlarged and can cause urinary problems 3, 4, 5.
• Tamsulosin is an alpha(1)-adrenergic receptor antagonist that works by relaxing the muscles in the prostate and bladder, making it easier to urinate 3.
• The medication is effective in improving urinary flow and reducing symptoms of BPH, such as difficulty starting to urinate, weak urine flow, and frequent urination 3, 5.
• Tamsulosin is also used to treat other conditions, such as acute urinary retention and chronic abacterial prostatitis 3.

Benefits of Tamsulosin

• Tamsulosin has been shown to be effective in improving symptoms of BPH and quality of life in patients with the condition 3, 5, 6.
• The medication has a rapid onset of action and can be taken once daily, making it a convenient treatment option 3, 4.
• Tamsulosin is generally well-tolerated, with common side effects including dizziness, abnormal ejaculation, and rhinitis 3, 5.

Combination Therapy

• Tamsulosin can be used in combination with other medications, such as dutasteride, to treat BPH 6.
• The combination of dutasteride and tamsulosin has been shown to be more effective than either medication alone in improving symptoms of BPH and reducing the risk of disease progression 6.
