Why do you have to stay out of the sun while taking amitriptyline?

While taking amitriptyline, it's important to stay out of the sun because this medication can increase your sensitivity to sunlight, potentially leading to a higher risk of sunburn or skin reactions. Additionally, amitriptyline can impair your body's ability to regulate temperature, making you more susceptible to heat-related illnesses. To minimize these risks, it's advisable to use sun protection and avoid prolonged sun exposure.
