Before Using
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 this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of candesartan in children 1 to 16 years of age.
Use of candesartan in newborn babies and infants up to 1 year of age is not recommended.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of candesartan in the elderly. However, elderly patients may be more sensitive to the effects of candesartan than younger adults, and are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving candesartan.
Drug Interactions
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. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Other Interactions
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 this medicine. Make sure you tell your doctor if you have any other medical problems, especially:
- Dehydration (fluid and electrolyte loss due to excessive perspiration, vomiting, diarrhea, prolonged diuretic therapy, dialysis, or dietary salt restriction) or
- Heart failure or
- Hyponatremia (low sodium in the blood) or
- Hypovolemia (low blood volume)—Use with caution. The blood pressure-lowering effects of candesartan may be increased.
- Kidney disease or
- Liver disease—Use with caution. The effects may be increased because of slower removal of the medicine from the body.
