Common Side Effects

• Though it is common for patients being treated with dexamethasone to experience side effects, many may not experience any side effects at all. The most common side effects include trouble sleeping, feeling as though you are whirling around, increase in appetite, increase in sweating, upset stomach, nervousness and changes in mood. Many of these side effects are mild, but if these symptoms become bothersome or persist, seek medical attention.
  
  

Cardiovascular and Metabolic

• Cardiovascular side effects are possible in those taking dexamethasone. These include abnormal heart rate, heart attack, cardiac enlargement, congestive heart failure, increase in blood pressure, edema, pulmonary edema, formation of blood clots in veins, swelling of the veins caused by blood clots and tearing of the walls of the ventricles or atria of the heart. The only metabolic side effect experienced is a negative balance of nitrogen in the body.
  
  

Gastrointestinal and Endocrine

• Common gastrointestinal side effects include inflammation of the stomach, nausea, vomiting, pancreatitis, formation of ulcers causing dangerous bleeding in the stomach, tearing of the small and large intestines (specifically in those with IBS) and the formation of ulcers in the throat. Reported endocrine side effects have included decreased tolerance of carbohydrates and glucose, menstrual cycle complications, high blood sugar and disturbances in growth of younger patients.
  
  

Dermatologic

• Many mild to serious dermatologic side effects have been reported by those being treated with dexamethasone. Included in these are acne, dry and scaly skin, changes in skin color, redness of the skin, troubles with wounds healing, rash, increase in sweating, hives throughout the body, thinning scalp hair and very thin and fragile skin.
