Abstract Peanut allergy (PA) is a common, burdensome childhood disease that in most patients continues into adulthood and has historically been untreatable. However, peanut oral immunotherapy (POIT) is increasingly being incorporated into allergy practices, using both the first FDA‐approved product, PTAH (previously AR101; Palforzia?, Aimmune Therapeutics), as well as store‐bought peanut products. POIT in preschoolers continues to gain more acceptance as evidence accrues that it is a safe and feasible approach that may have distinct advantages. There are many new therapeutic interventions currently under study with a variety of different approaches and potential mechanisms. With respect to other forms of immunotherapy, none are currently approved, but the epicutaneous approach is the most well‐studied and others are being actively investigated, including sublingual, subcutaneous, and intralymphatic. Biologics are gaining evidence both as adjunctive treatments to POIT and as monotherapy. Omalizumab is the most widely studied biologic for PA but others also have potential. Looking ahead to a future therapeutic landscape of choice, allergists will need to understand each patient's goal of treatment through shared decision‐making and fully evaluate the risks, benefits, and alternatives of each new therapy.
