1. What is Solifenacin Medreg and what is it used for

The active substance of Solifenacin Medreg belongs to a group of medicines called anticholinergics. These medicines reduce the activity of an overactive bladder. This action allows for longer intervals between visits to the toilet and increases the amount of urine held in the bladder. Solifenacin Medreg is used to treat symptoms of an overactive bladder. These symptoms include: urgent urination, which are unexpected, urgent needs to urinate, frequent urination, and incontinence related to not being able to get to the toilet in time.

2. Important information before taking Solifenacin Medreg.

When not to take Solifenacin Medreg:

• if you are allergic to solifenacin or any of the other ingredients of this medicine (listed in section 6),
• if you are unable to urinate or empty your bladder (urinary retention),
• if you have severe stomach or intestinal disorders (toxic megacolon, a complication associated with ulcerative colitis),
• if you have a muscle disease called myasthenia gravis, which can cause significant weakness of some muscles,
• if you have increased eye pressure with gradual vision loss (narrow-angle glaucoma),
• if you are undergoing dialysis,
• if you have severe liver function disorders,
• if you have severe kidney disease or moderate liver disease and are taking medicines that may delay the elimination of Solifenacin Medreg from the body (e.g., ketoconazole). Your doctor or pharmacist will provide information on this.

Before starting treatment with Solifenacin Medreg, you should inform your doctor if any of the above situations apply or have applied in the past.

Warnings and precautions

Before starting to take Solifenacin Medreg, you should discuss it with your doctor or pharmacist:

• if you have difficulty emptying your bladder (narrowing of the urethra) or urinating (weak urine stream). In such cases, the risk of urine accumulation in the bladder (urinary retention) is much higher,
• if you have gastrointestinal motility disorders (constipation),
• if there is a risk of slowing down the movement of the digestive tract (peristalsis, stomach and intestinal movements). Your doctor will provide information on this,
• if you have severe kidney function disorders,
• if you have moderate liver function disorders,
• if you have a burning stomach pain (hiatal hernia) or heartburn,
• if you have nervous system disorders (autonomic nervous system neuropathy). The objective and subjective symptoms of autonomic neuropathy vary depending on which part of the autonomic nervous system is affected. They may include: dizziness, fainting, irregular heartbeat, low blood pressure, especially when changing position to standing, abnormal sweating, vision disturbances, digestive disorders, urinary problems, sexual disorders, intolerance to physical exertion, burning sensation.

You should consult your doctor, even if the above warnings refer to current or past situations before starting to take Solifenacin Medreg. Before starting treatment with Solifenacin Medreg, your doctor will assess whether there are other causes of frequent urination (e.g., heart failure - insufficient strength of the heart muscle to pump blood or kidney disease). If a urinary tract infection occurs, your doctor will prescribe an antibiotic (an antibacterial medicine, acting on specific bacteria).

Solifenacin Medreg should not be used in children or adolescents under 18 years of age.
