Drug Allergy (cont.)
IN THIS ARTICLE
Most people who have mild to moderately severe allergic reactions to a drug do very well. With treatment and stopping of the drug, most people will be much better within 48-72 hours.
Most people also do well after a severe drug allergy if they are evaluated promptly by a medical professional and treatment is started. Some reactions can be life-threatening. People who have these reactions generally need to be admitted to the hospital.
