Symlosin SR, 0.4 mg, prolonged-release hard capsules
Tamsulosin hydrochloride
Symlosin SR is used to treat the symptoms of benign prostatic hyperplasia (a non-cancerous enlargement of the prostate gland), such as difficulty urinating.
The active substance of Symlosin SR is tamsulosin. Tamsulosin is an alpha-adrenergic receptor blocker that reduces the tension in the prostate and urethra. This makes it easier for urine to flow through the urethra and urinate.
Before taking Symlosin SR, discuss with your doctor or pharmacist:
PL/H/0159/001/IA/045/G
This medicine should not be given to children and adolescents under 18 years of age, as it is not intended for use in this patient group.
Tell your doctor or pharmacist about all the medicines you are taking, have recently taken, or might take.
Concomitant use of tamsulosin with other alpha-adrenergic receptor blockers (prazosin, alfuzosin) may cause hypotension.
It is particularly important to inform your doctor if you are being treated with medicines that may reduce the elimination of Symlosin SR from the body (medicines known as "strong CYP3A4 inhibitors", e.g. ketoconazole, erythromycin).
Symlosin SR should be taken after breakfast or after the first meal of the day, with a glass of water.
Symlosin SR is not intended for use in women.
There have been reports of ejaculation disorders, retrograde ejaculation, and failure to ejaculate.
There are no data on the negative impact of tamsulosin on the ability to drive and use machines. However, you should remember that Symlosin SR may cause dizziness.
This medicine contains less than 1 mmol (23 mg) of sodium per prolonged-release hard capsule, which means it is essentially "sodium-free".
Always take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
The recommended dose is one capsule per day.
Symlosin SR should be taken after breakfast or after the first meal of the day, with a glass of water. The capsule should be swallowed whole, with a glass of water, while sitting or standing (not while lying down).
The capsules should not be chewed or crushed, as this affects the gradual release of the active substance. However, the capsule can be opened and its contents swallowed without chewing.
If you feel that the effect of Symlosin SR is too strong or too weak, talk to your doctor or pharmacist.
If you have taken more Symlosin SR than prescribed by your doctor, contact your doctor or go to the hospital.
If you forget to take the medicine after breakfast, you can take it later the same day. Do not take a double dose to make up for the forgotten dose.
