cranial diabetes insipidus.

Taking other medicines

Some medicines and MINIRIN Melt may interfere with each other. These include:
loperamide, a medicine used to stop diarrhoea
medications which are known to release antidiuretic hormone (eg tricyclic antidepressants, selective serotonin reuptake inhibitors, chlorpromazine or carbamazepine) as they can increase the risk of fluid build up in the body.
Non-steroidal anti-inflammatory drugs (NSAIDs), medicines used to relieve pain and inflammation. NSAIDs may induce water retention/low sodium levels in the blood (hyponatraemia)
These medicines may be affected by MINIRIN Melt or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
