Before Using diazoxide
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For diazoxide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to diazoxide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Infants are more likely to retain (keep) body water because of diazoxide. In some infants, this may lead to certain types of heart problems. Also, a few children who received diazoxide for prolonged periods (longer than 4 years) developed changes in their facial structure.
Many medicines have not been tested in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of oral diazoxide in the elderly with use in other age groups.
|All Trimesters||C||Animal studies have shown an adverse effect and there are no adequate studies in pregnant women OR no animal studies have been conducted and there are no adequate studies in pregnant women.|
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking diazoxide, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using diazoxide with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
- Arsenic Trioxide
Using diazoxide with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Interactions with Food/Tobacco/Alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other Medical Problems
The presence of other medical problems may affect the use of diazoxide. Make sure you tell your doctor if you have any other medical problems, especially:
- Angina (chest pain)
- Gout—Diazoxide may make this condition worse
- Heart attack (recent)
- Heart or blood vessel disease
- Kidney disease—The effects of diazoxide may last longer because the kidney may not be able to get the medicine out of the bloodstream as it normally would
- Liver disease
- Stroke (recent)
Proper Use of diazoxide
Take diazoxide only as directed by your doctor. Do not take more or less of it than your doctor ordered, and take it at the same time each day.
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.
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 progress at regular visits, especially during the first few weeks of treatment, to make sure that diazoxide is working properly.
Before you have any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using diazoxide.
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.
Check with your doctor right away if symptoms of high blood sugar (hyperglycemia) occur. These symptoms usually include:
- Flushed, dry skin
