Possible side effects

Side effects of Phenadone depend on the dose, the duration and the frequency of administration. Short courses of dexamethasone usually are well tolerated with few and mild side effects. Long term, high dose dexamethasone usually will produce predictable and potentially serious side effects. Whenever possible, the lowest effective dose of dexamethasone should be used for the shortest possible length of time to minimize side effects. Alternate day dosing also can help reduce side effects.
Side effects include fluid retention, weight gain, high blood pressure, loss of potassium, headache, muscle weakness, puffiness, and hair growth on the face, thinning and easy bruising of skin, glaucoma, cataracts, peptic ulceration, worsening of diabetes, irregular menses, growth retardation in children, convulsions, stomach upset, headache, dizziness, menstrual changes, trouble sleeping, increased appetite, or weight gain may occur, depression, euphoria, insomnia, mood swings, personality changes, and even psychotic behavior. A very serious allergic reaction to this drug is rare. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Drug interactions

Drugs such as phenobarbital, ephedrine, phenytoin (Dilantin), and rifampin (Rifadin, Rimactane) may increase the breakdown of corticosteroids by the liver. As a result it may be lower blood levels and reduced effects. Therefore, the dose of corticosteroid may need to be increased if treatment with any of these agents is begun.

Missed dose

If you are taking this medication daily and on a regular schedule, and you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
