QL stands for Quantity limit, a pharmacy abbreviation.

Restriction set by an insurance plan or PBM on how much of a drug it will cover in a period, such as a maximum number of tablets per month. Exceeding the limit requires a prior authorization or override.

Example: Sumatriptan QL is 9 tablets per 30 days; submit an override for the extra fill.

Usage notes

Quantity limits are common for migraine drugs, opioids, sleep aids, erectile dysfunction drugs and specialty medicines. They aim to enforce labeled dosing and control costs, but may conflict with legitimate higher doses. Pharmacy claims reject with a message showing the plan's maximum.
