Please note: In the case where the prior authorization (PA) status column indicates PA, both the brand and generic (if available) require PA. Typically, the generic is preferred when available unless the brand-name drug appears on the MassHealth Brand Name Preferred Over Generic Drug List. In general, when requesting the non-preferred version, whether the brand or generic, the prescriber must provide medical records documenting an inadequate response or adverse reaction to the preferred version, in addition to satisfying the criteria for the drug itself. OTC
Combinations of antihistamines and decongestants (for example, chlorpheniramine/pseudoephedrine) may be payable under MassHealth, but may not be listed in the antihistamine table. Please refer to the OTC drug list. |

II. Therapeutic Uses
FDA-approved, for example:
- perennial or seasonal allergic rhinitis: oral/intranasal antihistamines
- chronic idiopathic urticaria: oral antihistamines only
- vasomotor (i.e., non-allergic) rhinitis: oral/intranasal agents
- acute urticaria: Quzyttir
Note: The above list may not include all FDA-approved indications.
III. Evaluation Criteria for Approval
Please note: In the case where the prior authorization (PA) status column indicates PA, both the brand and generic (if available) require PA. Typically, the generic is preferred when available unless the brand-name drug appears on the MassHealth Brand Name Preferred Over Generic Drug List. In general, when requesting the non-preferred version, whether the brand or generic, the prescriber must provide medical records documenting an inadequate response or adverse reaction to the preferred version, in addition to satisfying the criteria for the drug itself.
- All PA requests must include clinical diagnosis, drug name, dose, and frequency.
- A preferred drug may be designated for this therapeutic class. In general, MassHealth requires a trial of the preferred drug or clinical rationale for prescribing a non-preferred drug within a therapeutic class. Additional information about these agents, including PA requirements and preferred products, can be found within the MassHealth Drug List at www.mass.gov/druglist.
- For recertification requests, approval may require submission of additional documentation including, but not limited to, documentation of: some or all criteria for the original approval; response to therapy; clinical rationale for continuation of use; status of member’s condition; appropriate diagnosis; appropriate age; appropriate dose, frequency, and duration of use for requested medication; complete treatment plan; current laboratory values; and member’s current weight.
- Additional criteria may apply depending upon requested medication (see below).
azelastine 0.15% (generic Astepro) and olopatadine (generic Patanase) nasal sprays for allergic rhinitis
- Documentation of all of the following is required:

- an inadequate response (defined by 14 days of therapy), adverse reaction, or contraindication to two second-generation selective antihistamines.
- For quantities greater than one inhaler/month, in addition to the above criteria, documentation must be provided regarding an inadequate clinical response at the manufacturer's recommended doses.
SmartPA: Claims for one inhaler/month of azelastine 0.15% nasal spray and olopatadine nasal spray will usually process at the pharmacy without a PA request if the member has MassHealth medical claims for allergic rhinitis and a history of paid pharmacy claims for ≥ 14 days out of the last 180 days of one intranasal corticosteroid, azelastine 137 mcg nasal spray and two second-generation selective antihistamines.
