Other medicines and Atropine Injection
Tell your doctor, nurse or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. This is especially important with the following medicines as they may interact with your Atropine Injection:
- medicines to treat psychosis (such as clozapine) or depression
- amantadine (a medicine for Parkinson’s Disease)
- anti-histamines (medicines used to treat hay fever and allergies)
- medicines to regulate your heart (disopyramide and mexiletine)

- domperidone and metoclopramide (medicines used to prevent or treat sickness and vomiting)
- phenylephrine (may be present in cough or cold medicine)
medicines that you take by allowing them to dissolve slowly in your mouth – atropine may cause your mouth to become dry, making it more difficult for these medicines to dissolve.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before being given this medicine.
Driving and using machines
You should not drive or use machinery if you are affected by the administration of Atropine Injection.
