Apremilast (Otezla)
Apremilast (Otezla) is a prescription medicine that is approved to treat patients with psoriatic arthritis, moderate to severe plaque psoriasis, and the oral ulcers associated with Behçet's disease. Apremilast blocks the production of an enzyme called phosphodiesterase 4 (PDE4) and leads to a reduction in inflammation.
How To Take It
Apremilast is a tablet. Dosing begins at 10 mg on the first day with a gradual increase in doses over 5 days. The maximum dose is 30 mg twice a day. Starting at a low dose and gradually increasing, reduces nausea and diarrhea which may occur when starting apremilast. Apremilast can be taken with or without food. Tablets should not be crushed, split, or chewed. Dosing is the same for psoriatic arthritis, plaque psoriasis, and Behçet's disease. It can take can take up to 4 months to see improvement in symptoms with apremilast. It is a chronic medication that will be used continuously as long as it is effective and well tolerated.
Side Effects
The most common side effects of apremilast include diarrhea, nausea, upper respiratory tract infection, and headache. After two weeks of treatment, most patients who had symptoms of diarrhea and nausea no longer felt the symptoms and did not have to stop treatment. More serious side effects include weight loss and depression. Tell your doctor if you are having any feelings of depression, suicidal thoughts, or suicidal behavior.
Many patients do not experience side effects; however, for those who do, many of the minor side effects will improve with time. Side effects should be reported immediately and discussed with your rheumatologist. Apremilast does not lead to an increased risk of infection.
Tell Your Rheumatology Provider
Be sure to tell your rheumatology provider about all the medications you are taking, including over-the-counter drugs and natural remedies, as some medications and supplements can decrease the effect of apremilast. Examples of those medications include Phenytoin, Carbamazepine, Primidone, Phenobarbital, Rifampin, and St. John’s Wort.
Tell your rheumatology provider if you become pregnant or plan to become pregnant. There is not enough available data to know apremilast’s effect on pregnancy and breast feeding. If you become pregnant while taking apremilast, contact your rheumatology provider to see if this medication should be discontinued.
