MEDICATION DETAILS

Description

Flomaxtra XL 400 microgram Tablets

Flomaxtra XL contains tamsulosin hydrochloride and is used for the urinary symptoms of benign prostatic hyperplasia, an enlarged prostate. The extended release formulation is taken once a day and is designed to give cover across 24 hours. It is a medicine that requires a clinician to assess whether it is suitable for you.

How it works

Tamsulosin is an alpha blocker. As the prostate enlarges it presses on the urethra, and the muscle in the prostate and bladder neck tightens around it, which is what produces a weak stream, hesitancy, dribbling and frequent trips to the toilet. Tamsulosin relaxes that smooth muscle so the passage opens, improving flow. It eases the symptoms rather than shrinking the prostate itself.

How to use it

Swallow one tablet whole once a day with water, at the same time each day, with or without food. Do not crush or chew it, since that defeats the extended release design. Improvement is usually noticeable within the first couple of weeks. Rise slowly from sitting or lying for the first few days, as alpha blockers can cause dizziness at first.

Who it is for

It is for adult men with symptoms of an enlarged prostate where a clinician has confirmed it is appropriate. Your clinician needs to know about low blood pressure, fainting, liver or kidney problems, other blood pressure medicines and treatments for erectile dysfunction, which can combine to lower blood pressure further.

Safety and when to get advice

The most commonly reported effects are dizziness, reduced libido, erectile difficulty and reduced ejaculate volume. Seek prompt advice for fainting, a rapid or irregular heartbeat, chest pain, a sudden change in vision or hearing, or signs of an allergic reaction. Tell your eye surgeon that you take tamsulosin before any cataract surgery. See a doctor urgently if you cannot pass urine at all, or if you notice blood in your urine. Our UK pharmacy team can answer questions about this product before you buy.

Common questions

How soon does it work?
Many men notice a difference within the first couple of weeks of daily use.

Can I split the tablet?
No. It must be swallowed whole to keep the extended release working.

Why mention it before eye surgery?
Tamsulosin can affect the iris during cataract surgery, so the surgeon needs to know in advance.

Always read the patient information leaflet supplied with the pack before use.

Directions

Always adhere to your healthcare provider's instructions when taking Flomaxtra XL. The recommended dosage is one tablet daily, which can be taken with or without food. Swallow the tablet whole; avoid chewing or crushing it. If you miss a dose, take it as soon as you remember or continue with the next scheduled dose. Never double the dose to compensate for a missed one.

Ingredients

Each Flomaxtra XL 400 microgram tablet contains tamsulosin hydrochloride (equivalent to 367 micrograms of tamsulosin) as the active ingredient. Additional components include macrogol, magnesium stearate, butylhydroxytoluene, hypromellose, and yellow iron oxide E172.

Side Effects

As with any medication, Flomaxtra XL may cause side effects, although not everyone experiences them. Common side effects include dizziness, abnormal ejaculation (where semen enters the bladder instead of exiting through the urethra), weakness, headache, and runny or blocked nose. Uncommon side effects encompass palpitations, gastro-intestinal symptoms, and hypersensitivity reactions. If you experience any of these effects or other unusual symptoms, consult your healthcare provider.

Warnings

Prior to using Flomaxtra XL, consult your doctor if you have kidney problems or are scheduled for eye surgery. Inform your healthcare provider of all medications you are currently taking, as Flomaxtra XL can interact with certain drugs. This medication is not intended for use in women or individuals under 18 years of age. Exercise caution while driving or operating machinery, as Flomaxtra XL may cause drowsiness, blurred vision, dizziness, and fainting.
