Hyderabad, India and Princeton, NJ, USA, January 28, 2019 -

Dr. Reddy's Laboratories Ltd. (BSE: 500124, NSE: DRREDDY, NYSE: RDY) and its subsidiary, Promius Pharma, LLC today announced

the approval of TOSYMRA (previously known as DFN-02) by the U.S. Food and Drug Administration (FDA). TOSYMRA is indicated for the

acute treatment of migraine with or without aura in adults. TOSYMRA is the latest product to join the Promius Pharma acute migraine

treatment portfolio. The company is working toward commercialization of this product.

"We are excited about the approval of TOSYMRA. This approval

affirms our ability to develop well-differentiated products to meet the unmet needs of patients with migraine and HCPs treating

them," said G.V. Prasad, Co-Chairman and CEO, Dr. Reddy's Laboratories.

According to Dr. Anil Namboodiripad, PhD, President, Promius

Pharma, "TOSYMRA nasal spray is formulated using a proprietary novel excipient known as Intravail to achieve

blood levels similar to a 4-mg sumatriptan subcutaneous injection, resulting in rapid onset of action. Independent research shows

that 26% to 40% of migraine patients are not optimally controlled with their current treatment.1 For patients who suffer

from the debilitating and disruptive effects of migraine, there continues to be a need for reliable and efficacious treatment options.

At Promius, we are committed to developing new ways of improving patient experiences. TOSYMRA is a mist-like nasal spray that acts

rapidly and is well tolerated."
