An anonymous reader quotes a report from the New York Times: Melted capsules. Cloudy insulin. Pills that may no longer work. Doctors and pharmacists say the scorching temperatures enveloping the country could be endangering people’s health in an unexpected way: by overheating their medications. Millions of Americans now receive their prescription medications through mail-order shipments, either for convenience or because their health plans require it. But the temperatures inside the cargo areas of delivery trucks can reach 150 degrees Fahrenheit in the summer, according to drivers — far exceeding the range of 68 to 77 degrees recommended by the national organization that sets standards for drug handling.
Mail-order pharmacies say that their packaging is weather resistant and that they take special precautions when medication “requires specific temperature control.” But in a study published last year, independent pharmaceutical researchers who embedded data-logging thermometers inside simulated shipments found that the packages had spent more than two-thirds of their transit time outside the appropriate temperature range, “regardless of the shipping method, carrier, or season.” Extreme temperatures can alter the components in many medications, from pancreatic enzymes to the thyroid replacement drug levothyroxine to oral contraceptives, medical experts say.
Dr. Mike Ren, a primary care physician and an assistant professor in the department of family and community medicine at the Baylor College of Medicine, said that liquid medications like insulin or AUVI-Q, the epinephrine injection for allergic reactions, are often at heightened risk of degradation because excessive heat exposure can cause the evaporation of liquid components that were compounded at precise ratios. Aerosolized medications, too, are uniquely vulnerable because of the risk of pressure changes in the canister.
“Doctors recommend picking up your prescriptions at a local pharmacy whenever possible during hot summer months, particularly if your medication is liquid or aerosolized,” notes the report. “If you are enrolled in an insurance program that requires using a mail-order pharmacy, ask for an exception during the summer or, at the very least, contact the on-call pharmacist at the mail-order company to get more information about shipping practices and to ask for temperature-controlled packaging. You should do this even if the drug does not require refrigeration.”
Once you do get your medication, you should make sure to preserve it in a cool, dry environment, away from direct sunlight. If you’re flying, your prescriptions should be stored in your carry-on bag. They should never be left in a parked car.
Make headway at work. Continue to let things deteriorate at home.
