Neuroleptic side effects onset


Neuroleptic side effects onset

The rule of 4's:

Dystonia: 4 hours-4 days
Akathesia: 4 days-40 days
Extrapyramidal symptoms: 4 days-4 weeks
Tardive dyskinesia: 4 months (greater than)

· 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.
