Taking olanzapine with other medicines and herbal supplements

There are some medicines that may affect how olanzapine works.

Tell your doctor or pharmacist if you're taking any other medicines, including:

• carbamazepine, a medicine for epilepsy
• fluvoxamine, used to treat depression
• ciprofloxacin, an antibiotic
• medicines that make you feel calm or sleepy, including benzodiazepines, painkillers like morphine or tramadol, or antihistamines like chlorphenamine – olanzapine can increase the effects of these medicines and make you feel more sleepy

These are not all the medicines that may cause problems if you take them with olanzapine. For a full list, see the leaflet inside your medicine packet.
