Many medications are available as depot injections, including many typical and atypical antipsychotics,[2] as well as some hormonal medications and medication for opioid use disorder.[10][11][4] Depot injections of antipsychotics are used to improve historically low adherence in patients with diseases such as schizophrenia.[2] Different products may be administered or implanted either by a doctor or nurse, while some are designed to be administered by the patient themselves.[12] Self-administered depot injections are used to increase healthcare access and decrease the need to visit the doctor as frequently, especially in low and middle income countries.[12]
