According to a notification by the FDA, the recall of 26,530 units of 30-count bottles and 14,597 units of 90-count bottles is voluntarily initiated by the company through a letter to the regulator last month under 'Class-II' classification.
Venlafaxine Hydrochloride extended-release tablets are indicated for the treatment of major depressive disorder.
"Stability results found the product did not meet the drug release dissolution specifications," the regulator's website said.
Tablet dissolution is a standardised method for measuring the rate of drug release from a dosage form.
According to the US health regulator, Class II recall is a situation in which the use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.
When contacted, a Sun Pharma spokesperson refused to comment on the tablets' recall.
