Prior Authorization Required for Gabapentin Tablets

February 15, 2013 – MHCP Provider Update PRX-13-01

Effective February 19, 2013, Minnesota Health Care Programs (MHCP) changed the designation of generic gabapentin tablets to non-preferred.

As a non-preferred drug, generic gabapentin tablets are subject to prior authorization and require patients to switch to gabapentin capsules. Pharmacists may change the strength and dosage form of any given gabapentin prescription without contacting the prescriber (no new prescription is required); therefore, no interruption of therapy is anticipated. Switching from the tablet to the capsule formulation will likely increase the number of pills a patient takes in a day but should not change the number of times they have to take them.

Use of generic gabapentin capsules instead of tablets represents significant savings (estimated over $400,000 annually) to the MHCP program.


Generic gabapentin capsules do not require prior authorization.

To obtain a prior authorization call the MHCP Prescription Drug Prior Authorization Agent with the information on the MHCP Drug Prior Authorization Form (PDF) (DHS-4424) or fax the form to the agent.

If you have questions about this information, call the MHCP Provider Call Center at 651-431-2700 or 1-800-366-5411.
