Taking loratadine with other medicines and herbal supplements

Some medicines affect how loratadine works or can increase the chances of you having side effects.

Tell your doctor if you're taking:

• amiodarone, a medicine used to treat an irregular heartbeat
• cimetidine, an indigestion medicine
• erythromycin, an antibiotic
• any medicine that makes you feel sleepy, gives you a dry mouth or makes it difficult for you to pee – taking loratadine might make these side effects worse

Taking it with painkillers

You can take loratadine together with painkillers such as paracetamol or ibuprofen.
