Proper Use of diazoxide
Take diazoxide only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.
Follow carefully the special diet your doctor gave you. This is an important part of controlling your condition, and is necessary if the medicine is to work properly.
Test for sugar in your urine or blood with a diabetic urine or blood test kit as directed by your doctor. This is a convenient way to make sure your condition is being controlled, and it provides an early warning when it is not. Your doctor may also want you to test your urine for acetone.
Diazoxide comes in two forms: capsules and suspension. Do not switch from one dosage form to another unless your doctor tells you to do so.
Take diazoxide at the same time each day.
Swallow the capsule whole. Do not crush, break, or chew it.
Measure the oral suspension with a marked dropper that comes with the package. The average household teaspoon may not hold the right amount of liquid. Shake well before each use.
The dose of diazoxide will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of diazoxide. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using diazoxide
It is very important that your doctor check your or your child's progress at regular visits, especially during the first few weeks of treatment, to make sure that diazoxide is working properly. Blood and urine tests will be needed to check for unwanted effects.
Before you have any kind of medical tests, surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using diazoxide.
Hyperglycemia (high blood sugar) may occur if you have a fever or infection. Symptoms of high blood sugar include blurred vision, drowsiness, dry mouth, flushed and dry skin, a fruit-like breath odor, increased frequency and amount of urination, ketones in the urine, loss of appetite, nausea or vomiting, rapid and deep breathing, tiredness, or unusual thirst. If symptoms of high blood sugar occur, check your blood sugar level and call your doctor for instructions.
Symptoms of both low blood sugar and high blood sugar must be corrected before they progress to a more serious condition. In either situation, check with your doctor immediately.
Do not take any other medicine, unless prescribed or approved by your doctor, since some may interfere with diazoxide's effects. This especially includes over-the-counter (OTC) or nonprescription medicine such as that for colds, cough, asthma, hay fever, or appetite control.
