Magnesium Supplements (Systemic)
Before Using This Dietary SupplementIf you are taking this dietary supplement without a prescription, carefully
read and follow any precautions on the label. For magnesium supplements, the
following should be considered:
Allergies - Tell your health care professional if you have ever
had any unusual or allergic reaction to magnesium. Also tell your health care
professional if you are allergic to any other substances, such as foods, preservatives,
or dyes.
Pregnancy - It is especially important that you are receiving
enough vitamins and minerals when you become pregnant and that you continue
to receive the right amount of vitamins and minerals throughout your pregnancy.
The healthy growth and development of the fetus depend on a steady supply
of nutrients from the mother. However, taking large amounts of dietary supplements
during pregnancy may be harmful to the mother and/or fetus and should be avoided.
Breast-feeding - It is especially important that you receive the
right amount of vitamins and minerals so that your baby will also get the
vitamins and minerals needed to grow properly. However, taking large amounts
of a dietary supplement while breast-feeding may be harmful to the mother
and/or baby and should be avoided.
Children - Problems in children have not been reported with
intake of normal daily recommended amounts.
Older adults - Problems in older adults have not been reported with
intake of normal daily recommended amounts. Studies have shown that older adults may have lower blood levels of magnesium
than younger adults. Your health care professional may recommend that you
take a magnesium supplement.
Medicines or other dietary supplements - Although certain medicines or other dietary supplements should not be used
together at all, in other cases they may be used together even if an interaction
might occur. In these cases, your health care professional may want to change
the dose, or other precautions may be necessary. When you are taking magnesium,
it is especially important that your health care professional know if you
are taking any of the following:
-
Cellulose sodium phosphate - Use with magnesium supplements may
prevent cellulose sodium phosphate from working properly; magnesium supplements
should be taken at least 1 hour before or after cellulose sodium phosphate
-
Magnesium-containing preparations, other, including magnesium enemas - Use
with magnesium supplements may cause high blood levels of magnesium, which
may increase the chance of side effects
-
Sodium polystyrene sulfonate - Use with magnesium supplements
may cause the magnesium supplement to be less effective
-
Tetracyclines, oral - Use with magnesium supplements may prevent
the tetracycline from working properly; magnesium supplements should be taken
at least 1 to 3 hours before or after oral tetracycline
Other medical problems - The presence of other medical
problems may affect the use of magnesium. Make sure you tell your health care
professional if you have any other medical problems, especially:
-
Heart disease - Magnesium supplements may make this condition
worse
-
Kidney problems - Magnesium supplements may increase the risk
of hypermagnesemia (too much magnesium in the blood), which could cause serious
side effects; your health care professional may need to change your dose
