Before Using

Drug information provided by: Micromedex

If you are taking a dietary supplement without a prescription, carefully read and follow any precautions on the label. For these supplements, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group 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

Although there is no specific information comparing use of potassium supplements in children with use in other age groups, they are not expected to cause different side effects or problems in children than they do in adults.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of potassium supplements in the elderly with use in other age groups, they are not expected to cause different side effects or problems in older people than they do in younger adults.

Older adults may be at a greater risk of developing high blood levels of potassium (hyperkalemia).

Pregnancy

Potassium supplements have not been shown to cause problems in humans.

Breastfeeding

Potassium supplements pass into breast milk. However, this medicine has not been reported to cause problems in nursing babies.
