Medical treatments for sun poisoning include taking over-the-counter pain relievers to reduce pain and applying aloe lotion or gel to the skin, according to WebMD. Other ways to treat sun poisoning include getting out of the sun, taking a cool shower or bath, drinking extra fluids and covering a sunburn when going outdoors.
Though sun poisoning usually heals on its own, if a person experiences a sunburn that is extremely painful or blisters develop, it is important to seek medical attention, explains WebMD. People should also seek medical attention for sun poisoning if there is facial swelling, chills, fever, upset stomach or signs of dehydration.
Polymorphous light eruption is a form of sun poisoning, and in this case, those who are at risk are those who expose themselves to intense sunlight, states WebMD. There is also a form of the condition seen in Native Americans that is hereditary. Symptoms of this type of sun poisoning include small bumps on the skin and hives that appear in the hours following sun exposure. The treatment for polymorphous light eruption depends on how severe it is, and other than protecting the skin from the sun, treatment may not be necessary. In most cases, the rash clears up within a week to 10 days.
