Before starting Solifenacin succinate, your doctor will check whether there are other causes for your need to pass urine frequently (for example heart failure (insufficient pumping power of the heart) or kidney disease). If you have a urinary tract infection, your doctor will prescribe an antibiotic (a treatment against particular bacterial infections).

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

It is especially important to tell your doctor if you are taking:

• other anticholinergic medicines. The effects and side effects of both medications can be increased.
• cholinergic medicines as they can reduce the effect of Solifenacin succinate.

• medicines such as ketoconazole and itraconazole (antifungals), ritonavir and nelfinavir (used to treat HIV), verapamil and diltiazem (used to treat heart conditions or high blood pressure), may decrease the rate at which Solifenacin succinate is broken down by the body
• medicines such as rifampicin (an antibacterial), phenytoin and carbamazepine (used to treat epilepsy), may increase the rate at which Solifenacin succinate is broken down by the body.
• medicines such as bisphosphonates (used to treat osteoporosis), may cause or worsen inflammation of the gullet (oesophagitis).
