Can I take Abilify and Methylphenidate together?

Drug interaction guide

These two medicines work in opposite ways on a chemical in the brain called dopamine. Methylphenidate (used for ADHD) increases dopamine levels to help with focus, while Abilify (aripiprazole, an antipsychotic) is designed to manage or block dopamine activity. Taking them together can make both medicines less effective. It can also increase the risk of side effects like unusual body movements, restlessness, or a return of the symptoms you are trying to treat.

Why this happens

This is a pharmacodynamic interaction. Methylphenidate is a stimulant that increases synaptic dopamine, whereas aripiprazole is a partial dopamine agonist/antagonist. They compete for the same receptors in the brain, which can lead to 'antagonism' (where they cancel each other out) or an increased risk of movement disorders (extrapyramidal symptoms) as the balance of dopamine is altered.

You must speak to your doctor before taking these together. While they are sometimes prescribed together by specialists, your doctor will need to monitor you very closely. Watch out for any new or worsening 'ticks', jerky movements, or if your ADHD or mood symptoms seem to be getting worse. Do not change your dose of either medicine without medical advice.
