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
Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of clonidine and chlorthalidone combination in children with use in other age groups. However, children may be more sensitive than adults to clonidine. Clonidine overdose has been reported when children accidentally took this medicine.
Geriatric
Dizziness or lightheadedness and signs of too much potassium loss may be more likely to occur in the elderly, who are more sensitive to the effects of clonidine and chlorthalidone.
Breastfeeding
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.
