2. What you need to know before taking Tamisten

Do not take Tamisten:

• if you are allergic to the active ingredient or 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 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 may decrease the elimination of solifenacin from the body (e.g., ketoconazole). Your doctor or pharmacist will have informed you if this is the case.

Before starting treatment with Tamisten, inform your doctor if you have or have had any of the aforementioned diseases.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Tamisten:

• if you have problems emptying your bladder (obstruction of the bladder) or urinating (e.g., a weak urine flow). The risk of urine accumulation in the bladder (urinary retention) is much higher.
• if you have any obstruction of the digestive system (constipation).
• if you are at risk of decreased activity of the digestive system (movements of the stomach and intestine). 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 a hiatal hernia or heartburn.
• if you have an autonomic nervous disorder (autonomic neuropathy).

Before starting treatment with Tamisten, inform your doctor if you have or have had any of the aforementioned diseases.

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

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

Children and adolescents

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

Other medications and Tamisten

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication. It is especially important that you inform your doctor if you are taking:

• other anticholinergic medications, as the activity and side effects of both medications may increase.
• cholinergic medications, as they may reduce the effect of solifenacin.
• medications such as metoclopramide or cisapride, which make the digestive system work faster. Solifenacin may reduce their effect.
• medications such as ketoconazole, ritonavir, nelfinavir, itraconazole, verapamil, and diltiazem, which decrease the elimination of solifenacin from the body.
• medications such as rifampicin, phenytoin, and carbamazepine, as they may increase the elimination of solifenacin from the body.
• medications such as bisphosphonates, which may cause or worsen esophageal inflammation (esophagitis).
