Neutra Phos Side Effects, and Drug Interactions - Phosphates
Neutra Phos Side Effects, and Drug Interactions - Phosphates
SIDE EFFECTS
Gastrointestinal upset (diarrhea, nausea, stomach pain, and vomiting) may occur
with phosphate therapy. Also, bone and joint pain (possible phosphate-induced
osteomalacia) could occur. The following adverse effects may be observed (primarily
from sodium or potassium): headaches; dizziness; mental confusion; seizures;
weakness or heaviness of legs; unusual tiredness or weakness; muscle cramps;
numbness, tingling, pain, or weakness of hands or feet; numbness or tingling
around lips; fast or irregular heartbeat; shortness of breath or troubled breathing;
swelling of feet or lower legs; unusual weight gain; low urine output; unusual
thirst.
DRUG INTERACTIONS
The use of antacids containing magnesium,
aluminum, or calcium in conjunction with phosphate preparations may bind the
phosphate and prevent its absorption. Concurrent use of antihypertensives, especially
diazoxide, guanethidine, hydralazine, methyldopa, or rauwolfia alkaloid; or
corticosteroids, especially mineralocorticoids or corticotropin, with sodium
phosphate may result in hypernatremia. Calcium-containing preparations and/or
Vitamin D may antagonize the effects of phosphates in the treatment of hypercalcemia.
Potassium-containing medications or potassium-sparing diuretics may cause hyperkalemia.
Patients should have serum potassium level determinations at periodic intervals.
