1. What is Silamil and what is it used for

Solifenacin, the active substance of Silamil, belongs to a group of anticholinergic medicines. These medicines are used to reduce the activity of an overactive urinary bladder. This allows for less frequent use of the toilet and increases the amount of urine held in the bladder.
Silamil is used to treat symptoms associated with an overactive bladder.
These symptoms include: a sudden, urgent need to urinate without prior pressure on the bladder; frequent urination, incontinence due to the patient not being able to reach the toilet in time.

2. Important information before taking Silamil

When not to take Silamil

• if the patient is unable to urinate or empty the bladder completely (urinary retention)
• if the patient has severe stomach or intestinal disorders (including toxic megacolon, a complication of ulcerative colitis)
• if the patient has muscle disease (myasthenia gravis) that may cause significant weakness of some muscles
• if the patient has increased fluid pressure in the eyeball, with gradual loss of vision (glaucoma)
• if the patient is allergic to solifenacin or any of the other ingredients of this medicine (listed in section 6)
• if the patient is undergoing dialysis
• if the patient has severe liver disease
• if the patient has severe kidney disease or moderate liver disease and is taking medicines that may delay the elimination of Silamil from the body (e.g. ketoconazole). The doctor or pharmacist will inform if this warning applies to the patient.

Before starting to take Silamil, tell your doctor if any of the above disorders are present or have occurred in the past.

Warnings and precautions

Before taking Silamil, discuss with your doctor or pharmacist if:

• the patient has difficulty emptying the urinary bladder (narrowing of the urine outflow from the bladder) or urinating (e.g. weak urine stream) - the risk of urine accumulation in the bladder (urinary retention) is significantly higher
• the patient has intestinal obstruction (constipation)
• the patient is at risk of slowing down the movement of the digestive tract (gastrointestinal motility) - the doctor will tell the patient if this warning applies
• the patient has severe kidney disease
• the patient has moderate liver disease
• the patient has a hiatus hernia or gastroesophageal reflux disease
• the patient has autonomic nervous system disorders (autonomic neuropathy).

If any of the above situations apply to the patient now or have applied in the past, inform the doctor before taking Silamil.
Before starting to take Silamil, the doctor will assess whether there are other causes of frequent urination (such as heart failure or kidney disease). If the patient has a urinary tract infection, the doctor will prescribe an antibiotic (a medicine that fights certain bacterial infections).

Silamil and other medicines

Tell your doctor or pharmacist about all medicines the patient is taking, has recently taken, or might take.
It is especially important to inform the doctor about the use of such medicines as:

• other anticholinergic medicines (due to the possibility of increased action and side effects of both medicines).
• cholinomimetic medicines (they may weaken the action of Silamil).
• medicines that improve gastrointestinal motility, such as metoclopramide and cisapride (because Silamil may weaken their action).
• medicines such as ketoconazole, itraconazole (antifungal medicines), ritonavir and nelfinavir (used to treat HIV infection), verapamil and diltiazem (medicines used to treat heart disorders or high blood pressure) due to the possibility of slowing down the metabolism of Silamil.
• medicines such as rifampicin (an antibacterial medicine), phenytoin and carbamazepine (antiepileptic medicines) as they may accelerate the metabolism of Silamil.
• Medicines such as bisphosphonates (used to treat osteoporosis), as they may cause or exacerbate esophagitis.
