Atovaquone Oral Suspension, which is typically used to treat Pneumocystis jiroveci pneumonia—a form of pneumonia that frequently affects individuals with HIV—and is used in the prevention of Pneumocystis jiroveci pneumonia among immunocompromised individuals, is supposed to be protected against extremely low temperatures. However, the product was recalled after multiple users complained about their prescriptions being unusually gritty, which may have been attributable to exposure to low temperatures, according to the recall notice. It’s not the medication’s texture alone that may have been compromised by its exposure to temperature fluctuations. According to the FDA, while exposure to extremely cold temperatures may affect the product’s taste, texture, and appearance, most importantly, extreme cold may also impact its efficacy.ae0fcc31ae342fd3a1346ebb1f342fcb While manufacturer KVK Tech had received no reports of problems related to the use of the recalled medication at the time the recall was announced, the recall notice acknowledges that, “Severely immunocompromised patients who receive less effective Atovaquone Oral Suspension may experience inadequate treatment of serious and life-threatening infections.” If you have medication from the recalled lots in your possession, the FDA notice recommends that you stop using it now. The product should be returned to manufacturer KVK Tech at 110 Terry Drive, Newtown, PA 18940. Customers will be reimbursed for the cost of their medication.
