6.Contents of the package and additional information

The active ingredient of Tamisten belongs to the group of anticholinergics. These medications are used to reduce the activity of an overactive bladder. This allows you to have more time before needing to use the restroom and increases the amount of urine that your bladder can hold.

Tamisten is used to treat the symptoms of overactive bladder syndrome. These symptoms include: having a strong and sudden need to urinate without prior warning, having to urinate frequently or experiencing urine leakage due to not reaching the restroom in time.

Do not take Tamisten:

• if you are allergic to the active ingredient or to any of the other components of this medication (listed in section 6).
• if you have difficulty urinating or emptying your bladder completely (urinary retention).
• if you have a severe stomach or intestinal disorder (including toxic megacolon, a complication associated with ulcerative colitis).
• if you have a muscle disease called myasthenia gravis, which can cause extreme weakness in certain muscles.
• if you have high eye pressure with gradual loss of vision (glaucoma).
• if you are undergoing renal dialysis.
• if you have severe liver disease.
• if you have severe kidney disease or moderate liver disease and are being treated with medications that can reduce the elimination of solifenacina from the body (e.g. ketoconazole). Your doctor or pharmacist will have informed you if this is the case.

Inform your doctor before starting treatment with Tamisten if you have or have had any of the diseases mentioned above.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Tamisten:

• if you have difficulty emptying your bladder (bladder obstruction) or urinating (e.g. weak urine flow). The risk of urine accumulation in the bladder (urinary retention) is much higher.
• if you have any digestive system obstruction (constipation).
• if you have a risk of decreased digestive system activity (gastrointestinal motility). Your doctor will have informed you if this is the case.
• if you have severe kidney disease.
• if you have moderate liver disease.
• if you have hiatal hernia or heartburn.
• if you have a nervous system disorder (autonomic neuropathy).

Inform your doctor before starting treatment with Tamisten if you have or have had any of the diseases mentioned above.

Before starting treatment with Tamisten, your doctor will assess whether there are other causes for your need to urinate frequently (e.g. heart failure or kidney disease).

If you have a urinary tract infection, your doctor will prescribe an antibiotic (a treatment for certain bacterial infections).

Children and adolescents

Tamisten should not be used in children or adolescents under 18 years old (see section 3).

• cholinergic medications, which may reduce the effect of solifenacina.
• medications such as metoclopramide or cisapride, which make the digestive system work faster. Solifenacina may reduce their effect.
• medications such as ketoconazole, ritonavir, nelfinavir, itraconazole, verapamil, and diltiazem, which reduce the elimination of solifenacina from the body.
• medications such as rifampicin, phenytoin, and carbamazepine, which may increase the elimination of solifenacina from the body.
