1. What is Zevesin and what is it used for

The active substance of Zevesin belongs to a group of cholinergic antagonists. These drugs reduce the activity of an overactive urinary bladder. This action allows for longer intervals between visits to the toilet and increases the amount of urine held in the bladder. Zevesin is used to treat symptoms of an overactive bladder. These include: urgent urination, i.e., episodes of sudden, urgent need to urinate, frequent urination, and urinary incontinence, related to the fact that the patient did not have time to use the toilet.

2. Important information before taking Zevesin

When not to take Zevesin:

• in patients with hypersensitivity (allergy) to solifenacin or any of the other ingredients of this medicine (listed in section 6).
• if the patient cannot urinate or cannot empty the urinary bladder (urinary retention).
• if the patient has severe stomach or intestinal disorders (toxic megacolon, a complication associated with ulcerative colitis).
• in patients with a muscle disease called myasthenia gravis, which can cause significant weakness of some muscles.
• if the patient has increased fluid pressure in the eyeball, which progresses with gradual vision loss (narrow-angle glaucoma).
• if the patient is undergoing hemodialysis procedures.
• in patients with severe liver function disorders.
• if the patient has severe kidney disease or moderate liver disease and is taking medications that may delay the elimination of Zevesin from the body (e.g., ketoconazole). The doctor or pharmacist will provide information on this.

Warnings and precautions

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

• if the patient has difficulty emptying the urinary bladder (narrowing of the urine outflow tract) or urinating (weak urine stream). In such cases, the risk of urine accumulation in the bladder (urinary retention) is much higher.
• if the patient has gastrointestinal motility disorders (constipation).
• if there is a risk of slowing down the movement of the digestive tract (peristalsis). The doctor will provide information on this.
• if the patient has severe kidney function disorders.
• if the patient has moderate liver function disorders.
• if the patient has a severe stomach pain (hiatal hernia) or heartburn.
• if the patient has autonomic nervous system disorders (autonomic neuropathy).

Before starting treatment with Zevesin, you should inform your doctor if any of the above situations occur or have occurred in the past. Before starting treatment with Zevesin, the 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, the doctor will prescribe an antibiotic (an antibacterial drug that acts on specific bacteria).

Children and adolescents

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

Zevesin and other medicines

You should tell your doctor or pharmacist about all medicines you are taking now or have taken recently, as well as any medicines you plan to take. It is especially important to inform your doctor if you are taking:

• other cholinergic antagonists, as concomitant use of both medicines may lead to increased therapeutic and adverse effects.
• cholinergic receptor agonists, as they may weaken the effect of Zevesin.
• gastrointestinal motility enhancers, such as metoclopramide and cisapride, as Zevesin may weaken their effect.
• drugs such as ketoconazole, ritonavir, nelfinavir, itraconazole, verapamil, diltiazem, as they slow down the metabolism of Zevesin.
• drugs such as rifampicin, phenytoin, carbamazepine, as they may accelerate the metabolism of Zevesin.
• drugs such as bisphosphonates, as they may cause or exacerbate esophagitis.

Zevesin with food, drink, and alcohol

Zevesin can be taken with or without food.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, ask your doctor or pharmacist for advice before taking this medicine. You should not take Zevesin during pregnancy, unless it is absolutely necessary. You should not take Zevesin during breastfeeding, as solifenacin passes into breast milk.

Driving and using machines

Zevesin may cause blurred vision, and less often, drowsiness and fatigue. If such side effects occur, you should not drive or operate any machinery.

Zevesin contains lactose monohydrate

If you have been diagnosed with an intolerance to some sugars, you should contact your doctor before taking the medicine.
