Maintelyte (Magnesium Chloride Hexahydrate, Potassium Chloride, Sodium Chloride, Glucose, Sodium Acetate Trihydr)

Maintelyte is an intravenous electrolyte solution used in clinical situations that involve fluid loss or electrolyte disturbances.

• Electrolyte replacement: restores depleted electrolytes in patients with systemic losses.
• Fluid resuscitation: supplies volume and electrolytes to patients in shock or dehydration.
• Correction of hypomagnesemia: raises serum magnesium levels in deficient individuals.
• Correction of hypokalemia: replenishes potassium to normalize cardiac and muscular function.
• Correction of hyponatremia: increases sodium concentration to address low serum sodium.

• Maintelyte delivers water, sodium, potassium, magnesium, chloride, glucose and acetate directly into the bloodstream. The supplied ions restore extracellular electrolyte concentrations, supporting osmotic balance and cellular function, while glucose provides an energy substrate. Acetate is metabolized to bicarbonate, helping to correct mild acidosis. Together, these components correct fluid deficits and electrolyte imbalances.

Common Side Effects

• Infusion site pain or irritation.
• Mild hypernatremia or hyperkalemia.
• Mild hypocalcemia.
• Nausea or vomiting.
• Headache.
• Transient flushing.

Serious or Rare Side Effects

• Severe hypermagnesemia leading to respiratory depression.
• Severe hyperkalemia causing cardiac arrhythmia.
• Anaphylactic or severe allergic reaction.
• Fluid overload with pulmonary edema.
• Electrolyte imbalance resulting in seizures.
• Severe hypotension or shock.

Before initiating therapy, evaluate the patient's baseline electrolyte profile and renal function.

• Assess electrolyte levels before administration: check serum Mg, K, Na.
• Monitor cardiac function during infusion: watch for arrhythmias.
• Adjust infusion rate in renal impairment: reduce volume as needed.
• Avoid rapid infusion in heart failure: risk of fluid overload.
• Use compatible IV sets: ensure no precipitation with calcium-containing solutions.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Maintelyte may interact with other medications that affect electrolyte balance or renal function.

Major Interactions (Avoid)

• Calcium‑containing solutions: can precipitate magnesium.
• Loop diuretics: may exacerbate electrolyte shifts.
• ACE inhibitors: increase risk of hyperkalemia.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may mask signs of electrolyte imbalance.
• Nephrotoxic antibiotics: monitor renal function closely.
• Blood transfusions: watch electrolyte levels during and after transfusion.
