Always follow the instructions from a pharmacist or doctor, or the leaflet that comes with your medicine.
Dosage and how to take solifenacin
Dosage
Solifenacin tablets contain either 5mg or 10mg. The liquid contains 5mg in 5ml.
The usual dose of solifenacin is 5mg, taken once a day.
If your symptoms do not improve, your doctor may increase your dose to 10mg a day.
If you're taking solifenacin with tamsulosin (Vesomni or Vecit) for an enlarged prostate, the usual dose is 1 tablet once a day.
How to take it
You can take your dose at any time but try to take it at the same time each day.
Swallow your tablets whole with a drink of water. Do not chew or crush them.
If you're taking the liquid, it will come with a plastic syringe or spoon to help you measure your dose. If you do not have a syringe or spoon, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not measure the correct amount.
You can take solifenacin with or without food.
How long to take it for
Usually, you'll need to take solifenacin for a long time.
After 4 to 6 weeks your doctor will check that it's helping your symptoms. They'll also do a review every 6 to 12 months after that to check it's still working for you.
Take solifenacin until your doctor tells you to stop. Do not stop taking it just because you feel better.
If you forget to take it
If you forget to take a dose of solifenacin, take it as soon as you remember, unless you do not remember until the following day. In this case, skip the missed dose and take your next one at the normal time.
Do not take 2 doses to make up for a missed dose.
If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
If you take too much
Taking 1 extra dose of solifenacin is unlikely to harm you.
However, you may get more side effects, such as a dry mouth or headache.
Taking more than 1 extra dose can be dangerous. The amount of solifenacin that can lead to an overdose varies from person to person.
