LAKELAND, Fla. — Publix Super Markets Inc. has added montelukast, a prescription drug for asthma and allergies, to its Free Medication Program.

The food and drug retailer said that under the program, Publix Pharmacy will provides up to a 90-day supply of montelukast at no charge to patients for as a long as the medication is prescribed.

Publix will offer three dosages of montelukast free: 4-mg and 5-mg chewable tablets for children, and 10-mg tablets for adults.

Montelukast is indicated for the long-term treatment of asthma in adults and children and can be used to treat symptoms of indoor and outdoor allergies. It works by blocking a substance called leukotriene, which can trigger inflammation and allergy symptoms.

“We’re always happy to help our customers get the medications they need to treat chronic conditions,” Fred Ottolino, vice president of pharmacy operations for Publix, said in a statement. “Montelukast is an excellent addition to the list of generic prescription medications currently in our Free Medication Program, and it’s the first one we’ve added for the treatment of asthma.”

Other medications in the Publix Free Medication Program include amlodipine, lisinopril and metformin, as well as five common antibiotics (amoxicillin, ampicillin, sulfamethoxazole/trimethroprim (SMZ-TMP) and penicillin VK).

Overall, Publix operates 1,143 supermarkets, including approximately 1,000 in-store pharmacies, in Florida, Georgia, Alabama, Tennessee, South Carolina and North Carolina.
