Cautions with other medicines
Some medicines and solifenacin can affect each other. This can increase the chance of side effects.

- any medicine that makes you drowsy, gives you a dry mouth, or makes it difficult for you to pee – taking solifenacin might make these side effects worse
- itraconazole, a medicine used to treat fungal infections
- ritonavir, a medicine used to treat HIV

It's safe to take solifenacin with everyday painkillers like paracetamol and ibuprofen.
