Patients taking phenelzine to treat major depression disorder will need to be reviewed after the sponsor of the drug discontinued its supply, a leading psychiatrist says.

Australian-based pharmaceutical company Link Medical Products notified the TGA in April that it was no longer producing Nardil (phenelzine sulfate) 15mg tablets due to manufacturing issues.

In response to a nationwide shortage, the TGA had approved the supply of an alternative, overseas-registered product but has since been advised that these tablets are also not currently available. 

The medicines regulator has advised patients might be able to gain overseas supply through the Special Access Scheme.
