Neut Side Effects

Generic Name: sodium bicarbonate

Note: This page contains side effects data for the generic drug sodium bicarbonate. It is possible that some of the dosage forms included below may not apply to the brand name Neut.

It is possible that some side effects of Neut may not have been reported. These can be reported to the FDA here. Always consult a healthcare professional for medical advice.

For the Consumer

Applies to sodium bicarbonate: capsule, granule, powder, solution, tablet

Along with its needed effects, sodium bicarbonate (the active ingredient contained in Neut) may cause some unwanted effects. Although the following side effects occur very rarely when this medicine is taken as recommended, they may be more likely to occur if it is taken: in large doses, for a long time, or by patients with kidney disease.

If any of the following side effects occur while taking sodium bicarbonate, check with your doctor or nurse as soon as possible:

  • Frequent urge to urinate
  • headache (continuing)
  • loss of appetite (continuing)
  • mood or mental changes
  • muscle pain or twitching
  • nausea or vomiting
  • nervousness or restlessness
  • slow breathing
  • swelling of feet or lower legs
  • unpleasant taste
  • unusual tiredness or weakness

Some sodium bicarbonate side effects may not need any medical attention. As your body gets used to the medicine these side effects may disappear. Your health care professional may be able to help you prevent or reduce these side effects, but do check with them if any of the following side effects continue, or if you are concerned about them:

Less common
  • Increased thirst
  • stomach cramps

For Healthcare Professionals

Applies to sodium bicarbonate: compounding powder, intravenous solution, oral tablet

Metabolic

Chronic ingestion of bicarbonate may rarely cause intravascular volume expansion with resultant hyporeninemia and hypoaldosteronemia. In this rare circumstance, the serum potassium may be elevated.

Rare cases of sodium bicarbonate (the active ingredient contained in Neut) abuse have been associated with features of Munchausen syndrome. These patients often present with an otherwise unexplained hypokalemic hypochloremic metabolic alkalosis.

Hypernatremia may cause water retention, weight gain, and edema, which may be important in some patients with congestive heart failure, renal insufficiency, or severe liver disease.

Metabolic side effects have included metabolic alkalosis, hypernatremia/hyperosmolarity, hypochloremia, and hypokalemia. These effects have been associated with rapid or prolonged administration. Side effects have rarely included intravascular volume expansion with resultant hyporeninemia and hypoaldosteronemia.

Respiratory

The respiratory drive may be suppressed after bicarbonate administration due to increased venous C02 concentration. Without adequate ventilation, worsened systemic acidosis could develop.

Respiratory side effects have included suppressed respiratory drive.

Nervous system

Rapid infusion of hyperosmolar sodium bicarbonate (the active ingredient contained in Neut) has been associated with intraventricular hemorrhage in the pediatric literature.

Irritability and tetany have been associated with sodium bicarbonate-induced alkalosis or hypernatremia.

Due to greater permeability of the blood-brain barrier to hydrogen than to bicarbonate, the pH of cerebrospinal fluid may significantly decrease during sodium bicarbonate administration, which can cause mental stupor or coma.

Nervous system side effects have included irritability, tetany, mental stupor, coma, and intraventricular hemorrhage.

Local

Local side effects have included IV site pain, venous irritation, and extravasation. Cellulitis, tissue necrosis, ulceration, or skin sloughing have possibly been the result of extravasation. A slow rate of administration of a properly diluted solution into a large bore needle and vein is recommended if IV administration is necessary.

Cardiovascular

Cardiovascular side effects have included decreased cardiac contractility possibly resulting from infusion of sodium bicarbonate (the active ingredient contained in Neut) in patients with severe acidosis.

Experimentally, the administration of intravenous hypertonic sodium bicarbonate has been associated with increased serum osmolality, decreased ionized serum calcium (which is associated with decreased myocardial contractility), and peripheral vasodilation. Some experts recommend invasive hemodynamic monitoring in acidotic patients before the administration of bicarbonate.

Gastrointestinal

Gastrointestinal side effects associated with oral administration have rarely included gastric rupture.

As an antacid, sodium bicarbonate, especially after excess food or liquid, can cause excess gas release (when combined with gastric acid). The mortality associated with gastric rupture is as high as 65%.

Renal

Urinary alkalinization from bicarbonate can cause a falsely positive colorimetric assay for protein.

Renal side effects have rarely included "False proteinuria".
