Key takeaways
Methotrexate and Otezla (apremilast) are both medications that can be used to treat psoriasis, but they have some important differences. Methotrexate is an antimetabolite, while Otezla is a phosphodiesterase-4 (PDE-4) inhibitor. Methotrexate is also used for various cancers and autoimmune conditions like rheumatoid arthritis, whereas Otezla is used for psoriatic arthritis and mouth sores from Behçet’s disease. Methotrexate is available as an oral tablet and an injection, while Otezla is only available as an oral tablet. Methotrexate is available as a generic, making it more affordable, while generic versions of Otezla are not expected until at least 2028. Common side effects of methotrexate include mouth sores and nausea, while Otezla often causes nausea and diarrhea. Methotrexate can interact with certain antibiotics and NSAIDs. Be sure your prescriber and pharmacist have a complete list of your medications.
