Antacid Syrup Side Effects: What You Need to Know Before Use

Antacid syrup is commonly used to relieve acidity, indigestion, heartburn, and gas. While it is generally safe when used for short periods, overuse or long-term use can lead to side effects. Understanding these side effects can help you use the syrup safely and effectively.

Common Side Effects of Antacid Syrup:

1. Constipation or Diarrhea

   • Syrups containing aluminum hydroxide may cause constipation.

   • Syrups with magnesium hydroxide may cause diarrhea.

2. Nausea or Vomiting

   • Some people may feel nauseous after taking the syrup, especially in high doses.

3. Stomach Cramps or Bloating

   • Overuse can sometimes cause abdominal discomfort or excess gas.

4. Loss of Appetite

   • In rare cases, frequent use may affect hunger levels.

Serious But Rare Side Effects:

• Electrolyte Imbalance:
  Long-term use can disturb levels of calcium, magnesium, or phosphate in the body.

• Kidney Problems:
  High aluminum or magnesium levels may stress the kidneys, especially in patients with kidney disease.

• Allergic Reactions:
  Rash, itching, swelling (especially of the face/tongue/throat), and breathing problems are possible in rare allergic responses.

Precautions:

• Do not use for more than 2 weeks continuously without consulting a doctor.

• Always follow the recommended dosage.

• Keep a 1–2 hour gap if you are taking other medicines, as antacids can affect their absorption.

• Consult your doctor if you are pregnant, breastfeeding, or have kidney issues.
