Doctors Say Soaring Temperatures can Affect Quality of Pills

Extreme heat can affect medicines, say researchers.

As most medicines are designed to be stored at normal room temperatures, no drug should be exposed to temperatures higher than 86 degrees fahrenheit (30 degrees Celsius)," the Delhi Medical Association (DMA) said in a statement here.

According to doctors, chemists and pharmaceutical manufacturers should store there products at a controlled room temperature of 68 degrees fahrenheit (22 degrees Celsius) to 77 degrees fahrenheit (25 degrees Celsius).

"In fact, 68-77 degrees fahrenheit is the range in which manufacturers guarantee product integrity. Anywhere from 58 (14.5 degrees Celsius) to 86 degrees fahrenheit (30 degrees Celsius) is still fine," K.K. Kohli, state secretary of DMA, said.

He warned that certain medicines, including nitroglycerin (used to treat heart ailments) and insulin (used for diabetes), are particularly susceptible to heat.
