Hypophosphatemia is a low level of phosphorus in the blood.
The following may cause hypophosphatemia:
- Certain medicines, including acetazolamide, foscarnet, imatinib, pentamidine, and sorafenib
- Fanconi syndrome
- Too little vitamin D
- Overactive parathyroid gland (hyperparathyroidism)
Symptoms may include:
- Bone pain
- Muscle weakness
Treatment depends on the cause. Phosphate can be given by mouth or through a vein (IV).
How well you do depends on what has caused the condition.
When to Contact a Medical Professional
Call your health care provider if you have muscle weakness or confusion.
