Aripiprazole: What it treats and how to use it safely
Want a straightforward look at aripiprazole? This medicine is a commonly used atypical antipsychotic with a unique action: it calms overactive dopamine signals while still allowing some activity. That makes it useful for several conditions without the same level of sedation you see with other drugs.
Main uses you should know
Doctors prescribe aripiprazole for schizophrenia and bipolar disorder (mania and maintenance). It's also approved as an add-on for major depressive disorder when antidepressants alone don't work, and for irritability linked to autism in children. There are oral pills, liquid, short-acting injections for agitation, and long-acting monthly injections for people who need steady treatment and have trouble taking pills every day.
Practical dosing and what to expect
Typical oral doses range from about 2 mg up to 30 mg daily depending on the condition and response. Many prescriptions start in the low single digits and adjust after a few days or weeks. If you're switching from another antipsychotic, clinicians usually taper the old drug while starting aripiprazole to lower the chance of withdrawal or side effects.
Start slow and watch how you feel. Some people notice improvement in mood, thinking, or irritability within days, but full benefits often take a few weeks. If you get a long-acting injection, your doctor will explain the schedule and what to expect between doses.
Common side effects include restlessness or akathisia (a strong need to move), insomnia, nausea, and sometimes weight gain. Less commonly, people may develop metabolic changes like higher blood sugar or cholesterol. Rare but serious effects include movement problems (extrapyramidal symptoms) and unusual compulsive behaviors — report any new feelings like uncontrolled gambling or urges right away.
Drug interactions matter. Major players are CYP3A4 and CYP2D6: strong inhibitors can raise aripiprazole levels; strong inducers can lower them. Tell your doctor about antifungals, some antibiotics, certain antidepressants, and herbal products like St. John's wort.
Simple safety tips: keep regular follow-ups to check weight, blood sugar, and lipids; never mix with heavy alcohol; don't stop suddenly without medical advice; and carry a list of all meds in case of emergencies. If side effects like severe restlessness, muscle stiffness, high fever, or fainting occur, seek medical help fast.
If you're pregnant, planning pregnancy, or breastfeeding, bring this up with your prescriber—risks and benefits vary by situation. Finally, if remembering pills is hard, ask about the monthly injection. It can cut down missed doses and stabilize symptoms for many people.
