Treatment options for sun poisoning or severe sunburn include applying cold compresses, taking medications that reduce pain, and drinking lots of fluids, states WebMD. Avoiding the sun or covering the burned areas when outdoors may also be helpful.
Acetaminophen and ibuprofen may help treat sun poisoning, according to WebMD. Applying a moisturizer or aloe vera gel to the affected area may help as well. Wearing protective clothing when going outdoors and wearing a sunscreen with an SPF of more than 30 may prevent the problem. Sunburn that causes headaches, fever, chills or faintness requires medical attention. Other signs that require immediate medical care include swelling in the face and large, painful blisters.
