Cataract surgery — IFIS warning
Tamsulosin causes Intraoperative Floppy Iris Syndrome (IFIS) in up to ~90% of treated patients. Tell any ophthalmologist about tamsulosin use BEFORE cataract or glaucoma surgery — even years after stopping. The surgeon needs to know to use intracameral phenylephrine, capsular tension rings, or a different surgical approach.
First-dose orthostatic hypotension
First dose can cause sudden drop in BP, especially in dehydrated, elderly, or volume-depleted patients. Take the first dose at bedtime to reduce fall risk. Avoid combining with PDE5 inhibitors (sildenafil/tadalafil) within 4 hours.

How tamsulosin works

Tamsulosin is a uroselective alpha-1A adrenoceptor antagonist. The bladder neck and prostatic smooth muscle are densely populated with alpha-1A receptors; blocking them relaxes the dynamic component of bladder outlet obstruction without significantly affecting vascular alpha-1B receptors (which dominate blood vessels). This is why tamsulosin causes less postural hypotension than older non-selective alpha blockers (prazosin, doxazosin).

Tamsulosin treats symptoms only — it does not shrink the prostate. To shrink the gland and reduce long-term progression risk, a 5-alpha-reductase inhibitor (finasteride or dutasteride) is added; combination therapy is superior in glands >30 mL or PSA >1.5 ng/mL (CombAT trial).

Dosering

IndicatieDoseringOpmerkingen
BPH urinary symptoms0.4 mg once daily30 min after the same meal each day
Refractory symptoms0.8 mg once dailySpecialist-supervised; some markets do not approve this dose
Acute urinary retention0.4 mg/day × 7-10 days before catheter trial-without-catheterImproves trial-without-catheter success ~25-30%
Distal ureteric stones (off-label)0.4 mg/day × 4 weeksMedical expulsive therapy for stones <10 mm

Swallow whole — do not crush, chew, or open the capsule. Improvement in flow rate is typically noticed within 1-2 weeks; full benefit at 4-6 weeks.

Bijwerkingen

  • Common (1-10%): dizziness, headache, retrograde or absent ejaculation (~5-15% — reversible on stopping), nasal congestion (rhinitis), abnormal ejaculation
  • Minder vaak: orthostatic hypotension, syncope (especially first dose), palpitations, asthenia, decreased libido
  • Rare but important: priapism (medical emergency >4 hours), Stevens-Johnson syndrome, IFIS during cataract surgery

Geneesmiddelinteracties

GeneesmiddelEffect
Strong CYP3A4 inhibitors (ketoconazole, ritonavir, clarithromycin)Up to 3× tamsulosin AUC — avoid combination
PDE5-remmers (sildenafil, tadalafil, vardenafil)Additive hypotension — separate by ≥4 hours; tadalafil 5 mg OD has the cleanest profile if combination is needed
Other alpha blockersDo not combine — stacked vasodilation
CimetidineModest rise in tamsulosin levels — usually clinically insignificant
Tip: Stand up slowly, especially first thing in the morning, for the first 1-2 weeks. The orthostatic effect fades as the body adapts.

Veelgestelde vragen

When will I notice improvement?

Many men notice better flow within 7-14 days; full effect takes 4-6 weeks. If symptoms have not improved after 6 weeks, discuss with your clinician — combination with a 5-alpha-reductase inhibitor or alternative therapy may be warranted.

Can I take Temsunol Capsule on an empty stomach?

Manufacturer guidance is to take it 30 minutes after the same meal every day. Empty-stomach dosing increases peak plasma levels and the risk of orthostatic hypotension.

Will tamsulosin shrink my prostate?

No. Tamsulosin relaxes prostatic smooth muscle and improves urinary flow but does not change gland size. To shrink the prostate, a 5-alpha-reductase inhibitor (finasteride or dutasteride) is needed — often combined with tamsulosin in larger glands.

What about retrograde ejaculation?

About 5-15% of men experience reduced ejaculate volume or retrograde ejaculation (semen passes into the bladder). This is reversible on stopping the drug. It is more common with the 0.8 mg dose. The semen is harmless and reappears in the next urination.

I am having cataract surgery — does this matter?

Yes — tell your ophthalmologist immediately. Tamsulosin causes Intraoperative Floppy Iris Syndrome and the surgical approach needs to change. The effect persists for weeks-to-years after stopping, so do not just pause the drug — the surgeon still needs to know.

Mag ik alcohol drinken?

Modest alcohol is acceptable but increases dizziness and orthostatic hypotension risk. Avoid alcohol when starting therapy or after a dose increase.

Wat als ik een dosis vergeet?

Take it when you remember if you are still close to your normal time. If it is nearly time for the next dose, skip the missed dose — do not double up.

Can women take tamsulosin?

Tamsulosin is sometimes used off-label in women for refractory urinary retention or distal ureteric stones (medical expulsive therapy). It is not a first-line female lower urinary tract symptom drug.

Does it interact with my BP medication?

Tamsulosin lowers BP modestly. If you are on multiple antihypertensives (especially other alpha blockers, ACE inhibitors, ARBs, or diuretics), expect a small additional drop. Monitor for postural symptoms; rarely need a dose adjustment of either drug.

Is the once-daily dose enough?

Yes — tamsulosin has a 9-15 hour half-life and once-daily 0.4 mg gives steady symptom control. Splitting the dose adds inconvenience without benefit.

Other BPH & Urinary Medications

  • Urimax D — tamsulosin 0.4 mg + dutasteride 0.5 mg fixed combo for prostates >30 mL
  • Alfusin — alfuzosin 10 mg — alternative non-selective alpha blocker, slightly different side-effect profile
  • Silofast — silodosin 4/8 mg — another uroselective alpha-1A blocker; higher retrograde-ejaculation rate but less BP effect
  • Finpecia — finasteride 1 mg — 5ARI for hair loss; 5 mg version for BPH gland shrinkage
  • Urotel XL — tolterodine 4 mg ER — for overactive bladder symptoms, NOT for BPH
