Treatment
The goals of treatment are relief of acute symptoms and prevention of further attacks.
Attacks are seldom severe enough to require emergency treatment. However, weakness can become worse with repeated attacks, so treatment to prevent the attacks should occur as soon as possible.
Glucose or other carbohydrates (sugars) given during an attack may reduce the severity. Intravenous calcium or diuretics such as furosemide may need to be given to stop sudden attacks. Intravenous glucose and insulin cause potassium to move into the cell and may reduce weakness without a loss of total body potassium.
A high-carbohydrate diet may be recommended.
Acetazolamide, a medication that prevents attacks of familial periodic paralysis, is also effective in preventing attacks of hyperkalemic periodic paralysis. Thiazide diuretics such as chlorothiazide are also effective and have fewer side effects than acetazolamide.
