Neuroleptic Side Effects Onset

Psychiatry/Nervous
DATE - The rule of 4's

Dystonia: 4 hours - 4 days
Akathesia: 4 days - 40 days
Tardive dyskinesia: >4 months 
Extrapyramidal symptoms: 4 days - 4 weeks


Note that tardive is obviously the latest one to happen (tardive = tardy/late)

Note that the first letters of these four classic symptoms spell "DATE", and this mnemonic is the dates when they occur.
