Long-acting injectable (LAI) medications are an available treatment option for individuals living with bipolar disorder. Bipolar disorder is a chronic mental health condition marked by notable shifts in mood, energy levels, and activity, encompassing episodes of elevated mood (mania or hypomania) and periods of depression. For many, managing this condition involves consistent medication use. These injectable treatments offer an alternative to daily oral medications, providing a sustained release of medication over an extended period. This can help to simplify treatment regimens and support consistent symptom management.
Understanding Long-Acting Injectable Medications
Long-acting injectable medications deliver a steady supply of medicine into the body over several weeks or months, differing significantly from daily oral pills. When administered, these medications typically form a “depot” or small reservoir in the muscle, often in the arm or buttocks. From this depot, the medication is gradually released into the bloodstream over time. This controlled release mechanism ensures that a consistent level of medication is maintained in the body, which can contribute to more stable symptom control. The sustained release means that patients do not need to remember to take medication every day, reducing the frequency of dosing from daily to monthly or even less often.
Available Injectable Treatments for Bipolar Disorder
Several long-acting injectable antipsychotic medications are used in the management of bipolar disorder. Aripiprazole, available as Abilify Maintena, is an injectable form typically administered once a month for the maintenance treatment of bipolar I disorder. Another formulation, aripiprazole lauroxil (Aristada), can be administered every 4 to 8 weeks. These medications work by balancing certain brain chemicals to help stabilize mood.
Olanzapine pamoate, known as Zyprexa Relprevv, is another injectable option used for the treatment of mania in bipolar I disorder, typically given every two to four weeks. Paliperidone palmitate, under brand names like Invega Sustenna and Invega Trinza, is also utilized. While Invega Sustenna is typically given monthly, Invega Trinza can be administered every three months.
Who Might Benefit from Injectable Medications?
Long-acting injectable medications offer particular advantages for various individuals managing bipolar disorder. A primary benefit is improved medication adherence. This consistent medication level reduces the risk of mood instability and symptom relapse that can occur when daily doses are missed.
Injectable medications can also provide greater mood stability, as they ensure a steady amount of medication in the body, which helps prevent the fluctuations that sometimes arise from inconsistent oral dosing. These treatments can also foster more regular contact with healthcare providers through scheduled injection visits, which supports ongoing monitoring and adjustments to the treatment plan.
Receiving and Managing Injectable Treatment
The administration of long-acting injectable treatment for bipolar disorder is performed by a healthcare professional in a clinic or hospital setting. The injection is typically given into a muscle, such as the deltoid (arm) or gluteal (buttock) muscle. The frequency of injections depends on the specific medication, ranging from every two weeks to monthly or even every few months.
Patients may experience some common side effects, similar to those seen with oral forms of the same medication, as well as reactions at the injection site. These can include pain, swelling, redness, or itching at the injection site. Other potential side effects may involve weight gain, drowsiness, headache, nausea, dizziness, or restlessness. It is important for individuals to communicate any side effects or concerns to their healthcare provider. Regular monitoring and attending all scheduled appointments are essential to ensure the treatment is effective and well-tolerated, allowing for any necessary adjustments to the care plan.
