Sodium Bicarbonate is an antacid medicine widely used to neutralise excess stomach acid and relieve symptoms such as acidity, heartburn, sour stomach, and indigestion. It works by rapidly increasing the pH level in the stomach, providing quick symptomatic relief. It may also be used in specific medical conditions where acid-base balance needs correction, under medical supervision. This medicine offers fast, short-term relief and is generally well tolerated when used correctly.

Sodium Bicarbonate is a widely used antacid formulation designed to counteract excess gastric acidity and provide rapid relief from symptoms such as heartburn, acidity, bloating, and sour burps. As an alkalinising agent, it works by neutralising hydrochloric acid in the stomach, thereby reducing irritation of the stomach and food pipe. The medicine is commonly recommended for individuals experiencing occasional acidity due to dietary choices, stress, irregular meals, or mild gastrointestinal discomfort.

Beyond its antacid properties, Sodium Bicarbonate also plays a role in certain medical settings where acid-base imbalance occurs, such as metabolic acidosis or urinary alkalinisation. However, such uses require medical guidance and should not be self-administered.

Its onset of action is quick, often bringing relief within minutes, making it suitable for short-term symptomatic management. However, it is not intended for long-term use, especially in people with kidney issues, high blood pressure, or those on a sodium-restricted diet. Overuse may lead to electrolyte imbalance, excess alkalinity, or fluid retention due to its sodium content. Sodium Bicarbonate is usually taken orally with a glass of water, and the dosage should be followed exactly as recommended by a healthcare provider. If symptoms persist or worsen despite treatment, medical evaluation is essential to rule out underlying gastrointestinal disorders. Overall, Sodium Bicarbonate is an effective and fast-acting remedy for acidity when used responsibly and for short-term relief.

• Relief from heartburn and acidity

• Management of sour stomach or indigestion

• Neutralising excess gastric acid after heavy or spicy meals

• Temporary relief from bloating and gas associated with hyperacidity

• Used in urinary alkalinisation to make urine less acidic (medical supervision required)

• Support in the management of metabolic acidosis in specific clinical conditions

• Helps enhance the elimination of certain drugs through urine alkalinisation

• Used as an adjuvant treatment in certain kidney-related acid-base disturbances (doctor-directed use only)

Sodium Bicarbonate provides rapid relief from acidity-related discomfort by neutralising excess stomach acid almost immediately. This makes it particularly helpful for people who frequently experience heartburn after meals or during stressful periods. Its quick action offers comfort within minutes, helping restore normal digestive function.

Additionally, in medical settings, Sodium Bicarbonate acts as an effective alkalinising agent to correct acid-base imbalance when indicated. It can also support kidney function in certain conditions by reducing urine acidity. While primarily an antacid, its broader benefits highlight its clinical importance when used responsibly under medical supervision.

• Bloating or gas

• Stomach cramps

• Frequent urination

• Increased thirst

• Nausea

• Headache

• Swelling in feet or ankles (due to sodium retention)

• Muscle twitching or irritability (rare, linked to electrolyte imbalance)

• High sodium levels (hypernatraemia)

• Metabolic alkalosis in case of excessive dosing

Always seek medical attention if severe symptoms occur.

• Take Sodium Bicarbonate exactly as prescribed or as directed on the label.

• Swallow the tablet with a full glass of water.

• Do not take on an overly full stomach.

• Avoid taking it immediately after large meals.

• Maintain the recommended dosing intervals and avoid exceeding the daily limit.

• Consult a doctor if symptoms last more than 2 weeks.

Sodium Bicarbonate works as a systemic alkalinising agent by neutralising stomach acid through a chemical reaction that converts hydrochloric acid into sodium chloride, water, and carbon dioxide. This increases the gastric pH and reduces irritation in the oesophagus and stomach, providing relief from acidity and heartburn.

Once absorbed, it also increases the pH of blood and urine, which can be beneficial in conditions such as metabolic acidosis or for increasing the elimination of certain medications. The rapid onset of action makes it a commonly used antacid for immediate relief. However, its sodium load and potential systemic effects mean that it should be used cautiously in patients with cardiac or kidney problems.

• Use Sodium Bicarbonate for short-term relief only.

• Avoid exceeding recommended doses to prevent alkalosis.

• Do not use it as a routine remedy for chronic acidity.

• If heartburn occurs frequently, seek a medical evaluation.

• Keep a gap of at least 2 hours between this medicine and other medications.

• Store in a cool, dry place away from moisture.

• Keep out of reach of children.

• Do not use it after the expiry date.

• Keep the tablets in their original packaging.

Sodium Bicarbonate may interact with certain foods and beverages that increase acidity, reduce its effectiveness, or lead to discomfort.

Possible interactions include:

• Citrus fruits (may increase acid production)

• Caffeinated drinks

• Alcohol

• Large, heavy meals

• Foods high in sodium (risk of sodium overload)

Avoid taking the medicine immediately after eating heavy or spicy meals.

Sodium Bicarbonate may affect the absorption or effectiveness of several medicines by altering stomach and urine pH.

Possible interactions include:

• Tetracycline antibiotics

• Iron supplements

• Aspirin

• Certain antifungals

• Lithium

• Diuretics

Maintain a minimum 2-hour gap between Sodium Bicarbonate and other medicines unless advised otherwise.

Patients with certain health conditions must use Sodium Bicarbonate cautiously because its sodium content and alkalinising effect may worsen symptoms.

Use with caution in:

• Kidney disease

• Heart failure

• High blood pressure

• Liver disease

• Oedema or fluid retention

• Conditions requiring low-sodium diet

Always consult a doctor if you have any chronic medical condition.

The typical recommended dose is as advised by a healthcare professional, depending on the condition being treated. For acidity relief, it is usually taken as needed, not exceeding the daily limit set by your doctor. Long-term use is not recommended without medical supervision.

Overdose may lead to metabolic alkalosis, muscle twitching, irritability, nausea, vomiting, and electrolyte imbalance. In severe cases, it may cause confusion or breathing difficulties. Seek immediate medical help if an overdose is suspected.

If you miss a dose, take it as soon as you remember unless it is close to the time for your next scheduled dose. Do not double the dose to compensate for the missed one. Since Sodium Bicarbonate is often taken as needed for symptoms, you may simply skip the missed dose if you are symptom-free. Always follow your doctor’s instructions for regular or long-term dosing schedules.
