Welcome on HCM.
You told you got some problem after iron injection and what you elaborated that is caused by allergy
to inject able iron.
Because you became depressed due to this untoward effect doctor prescribed you antidepressant.
If you are confident with my explanation, than you can withdraw cipralex
slowly and you will be ok by anti allergic treatment with in 2 wks.
If needed, corticosteroid can be taken for short term; there is no harm in that.
Get well soon.
