If hives are mentioned as a potential side effect of a medication that you are taking, call your doctor right away. Your doctor may decide to try a different medication, but do not stop taking the medication without asking your doctor first. Treatment for hives includes antihistamines that can cause drowsiness and corticosteroids that can lead to weight gain and elevations in blood glucose levels. Corticosteroids should never be used for an extended period of time as this can cause serious side effects, such as muscle weakness and increased risk of cataracts and glaucoma.
Wear loose, light clothing like cotton. Avoid scratching your skin and avoid known triggers. Shower using warm or cool water and use a cleanser that is gentle and non-drying.
