1. What Phosphates infusion is and what
it is used for
In this leaflet this medicines is referred to as Phosphates infusion.
Phosphates infusion is used when there are low levels of phosphate
in the blood.
Phosphate is the most common form of phosphorus. Phosphorus is a
mineral found in many foods, such as milk, cheese, dried beans, peas,
nuts, and peanut butter. In the body, phosphate is critical for energy
storage and metabolism, for the utilisation of many B-complex vitamins,
to buffer body fluids, for proper muscle and nerve function, and for
maintaining calcium balance. Phosphorus is vital to the formation of
bones and teeth, and healthy bones and soft tissues require calcium and
phosphorus to grow and develop throughout life.

4. Possible side effects
Like all medicines Phosphates infusion can cause side effects, although
not everybody gets them.
Prolonged infusion of Phosphates infusion may result in raised
phosphate levels in the blood (hyperphosphataemia). This may lead to
reduced calcium levels in the blood (hypocalcaemia) with muscle spasm
(tetany), fits (convulsions) or nervous excitability and to deposition of
insoluble calcium in soft tissue. This tissue calcification may cause low blood
pressure (hypotension) and organ damage and result in kidney failure.
If too much Phosphates infusion is administered, it may cause raised
potassium (hyperkalaemia) and sodium (hypernatraemia) electrolyte levels.
Symptoms associated with increased potassium levels include:
• muscle weakness
• lack of energy
• mental confusion
• numbness/pins & needles of the extremities
• abnormal heart rhythms and blood pressure.
Symptoms associated with increased sodium levels include:
• loss of water from the brain resulting in sleepiness and confusion,
which could progress to convulsions, coma and breathing failure
• reduced amounts of saliva and tears
• increased heart rate and blood pressure • irritability and weakness
Intravenous administration may also be associated with pain and
inflammation at the injection site.
