• If you have any doubts, consult your doctor or pharmacist.
• This medication has been prescribed only to you, and you should not give it to others who have the same symptoms as you, as it may harm them.

Solifenacina/tamsulosina is a combination of two different medications called solifenacina and tamsulosina in a tablet. Solifenacina belongs to a group of medications called anticholinergics and tamsulosina belongs to a group of medications called alpha-blockers.

Solifenacina/tamsulosina is used in men to treat both moderate to severe filling symptoms and emptying symptoms of the lower urinary tract caused by problems related to the bladder and by the enlargement of the prostate (benign prostatic hyperplasia). Solifenacina/tamsulosina is used when previous monotherapy treatment for this condition did not alleviate symptoms sufficiently.

When the prostate becomes enlarged, urinary problems (emptying symptoms) such as delayed urination (difficulty starting urination), reduced urine flow (weak stream), dripping, and sensation of incomplete bladder emptying may occur. At the same time, the bladder is also affected and contracts spontaneously at times when urination is not desired. This causes filling symptoms such as changes in bladder sensation, urgency (having a strong and sudden desire to urinate without prior warning) and having to urinate more frequently.

Solifenacina reduces involuntary bladder contractions and increases the amount of urine that the bladder can store. Therefore, you can expect to wait longer before having to go to the bathroom. Tamsulosina allows urine to pass more easily through the urethra and facilitates urination.

You should not use Solifenacina/Tamsulosina Stadafarma if:

• You are allergic to solifenacina or tamsulosina or any of the other components of this medication (listed in section 6).
• You are undergoing renal dialysis.
• You have a severe liver disease.
• You have a severe kidney disease and are being treated with medications that can reduce the elimination of solifenacina/tamsulosina from the body (for example, ketoconazol, ritonavir, nelfinavir, itraconazol). Your doctor or pharmacist will inform you if this is the case.
• You have a moderate liver disease and are being treated with medications that can reduce the elimination of solifenacina/tamsulosina from the body (for example, ketoconazol, ritonavir, nelfinavir, itraconazol). Your doctor or pharmacist will inform you if this is the case.
• You have a severe stomach or intestinal condition (including toxic megacolon, a complication associated with ulcerative colitis).
• You have a muscle disease called myasthenia gravis, which can cause extreme weakness in certain muscles.
• You have increased pressure in the eyes (glaucoma), with gradual loss of vision.
• You experience fainting due to a decrease in blood pressure when changing position (sitting or standing); this is known as orthostatic hypotension.

Inform your doctor if you think you have any of these conditions.

Warnings and precautions

Consult your doctor or pharmacist before starting to use Solifenacina/Tamsulosina Stadafarma if:

• You have difficulty eliminating liquid (urinary retention).
• You have any obstruction of the digestive system.
• You are at risk of decreased activity of the digestive system (gastrointestinal motility). Your doctor will inform you if this is the case.
• You have a hiatal hernia or stomach burning and/or are taking medications that can cause or worsen esophagitis.
• You have a certain type of nervous system disease (autonomic neuropathy).
• You have a severe kidney disease.
• You have a moderate liver disease.

Regular medical check-ups are necessary to monitor the development of the condition being treated.

Solifenacina/tamsulosina may affect blood pressure, which can cause dizziness, drowsiness, or rarely, fainting (orthostatic hypotension). You should sit or lie down if you experience any of these symptoms until they have disappeared.

If you are scheduled to undergo eye surgery due to cataracts or increased pressure in the eyes (glaucoma), please inform your ophthalmologist that you have previously used, are using, or plan to use solifenacina/tamsulosina. The specialist can then take the necessary precautions regarding medication and surgical techniques. Ask your doctor if you should or should not temporarily stop taking this medication when undergoing eye surgery for cataracts or increased pressure in the eye (glaucoma).

Children and adolescents

Do not administer this medication to children and adolescents.

Use of Solifenacina/Tamsulosina Stadafarma with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

It is especially important to inform your doctor if you are using:

• Medications such as ketoconazol, erythromycin, ritonavir, nelfinavir, itraconazol, verapamil, diltiazem, and paroxetine that reduce the rate at which solifenacina/tamsulosina is eliminated from the body.
• Other anticholinergic medications, as the effects and adverse effects of both medications can be intensified if you are taking two medications of the same type.
• Cholinergic medications, as they can reduce the effect of solifenacina/tamsulosina.
• Medications such as metoclopramide and cisapride, which can accelerate the functioning of the digestive system. Solifenacina/tamsulosina can reduce their effect.
• Other alpha-blockers, as they can cause an undesirable decrease in blood pressure.
• Medications such as bisphosphonates, which can cause or exacerbate inflammation of the esophagus (esophagitis).

Use of Solifenacina/Tamsulosina Stadafarma with food and drinks

Solifenacina/tamsulosina can be taken with or without food, according to your preferences.

Pregnancy, breastfeeding, and fertility

Solifenacina/tamsulosina is not indicated for use in women.

In men, abnormal ejaculation (alteration of ejaculation) has been reported. This means that semen does not release through the urethra, but rather goes to the bladder (retrograde ejaculation) or the volume of semen is reduced or non-existent (ejaculatory insufficiency). This phenomenon is harmless.

Driving and operating machinery

Solifenacina/tamsulosina can cause dizziness, blurred vision, fatigue, and, less frequently, somnolence. If you experience these adverse effects, do not drive or operate machinery.

Solifenacina/Tamsulosina Stadafarma contains sodium

This medication contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".

Follow exactly the administration instructions for this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

The maximum daily dose is one tablet containing 6 mg of solifenacina and 0.4 mg of tamsulosina, taken orally. It can be taken with or without food, according to your preferences. Do not crush or chew the tablet.

If you take more Solifenacina/Tamsulosina Stadafarma than you should

If you have taken more tablets than you were told to, or if someone else takes your tablets by accident, contact your doctor, pharmacist, or hospital immediately for advice.

In case of overdose, your doctor may treat you with activated charcoal; emergency gastric lavage may be useful if performed within one hour of the overdose. Do not induce vomiting.

The symptoms of an overdose may include: dry mouth, dizziness, and blurred vision, seeing things that are not there (hallucinations), over-excitement, convulsions, difficulty breathing, increased heart rate (tachycardia), inability to completely or partially empty the bladder or to urinate (urinary retention), and/or unwanted increase in blood pressure.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service. Phone: 91 562 04 20, indicating the medication and the amount ingested.

If you forgot to take Solifenacina/Tamsulosina Stadafarma

Take your next Solifenacina/Tamsulosina tablet as usual. Do not take a double dose to compensate for the missed doses.

If you interrupt treatment with Solifenacina/Tamsulosina Stadafarma
