Ulcer & Stomach Acid Bloating & Gas

How it works

Neutralizes gastric acid by binding hydrogen ions through base-acid reaction, while magnesium trisilicate forms a protective gel layer on the gastric mucosa; dried aluminum hydroxide additionally absorbs pepsin and bile salts, reducing mucosal irritation and promoting healing of acid-damaged tissue.

How to take this drug

Chew or swallow 1 to 2 tablets between meals and at bedtime, or whenever you feel heartburn or stomach discomfort. You can take it up to 3-4 times a day. It works best when taken between meals or about 1 hour after eating. Some forms come as liquid — shake the bottle well and take 1-2 teaspoons as needed.

What if I Miss a Dose?

Since this medicine is usually taken only when you feel symptoms like heartburn or stomach pain, there is no strict dosing schedule to miss. Simply take it when you need it, but do not take more than the recommended daily amount.

What to watch out for

Do not use this antacid as a long-term solution — if your stomach problem continues for more than 2 weeks, see a doctor as it could be something more serious. Buy from a registered pharmacy and look for the NAFDAC number on the pack. Do not take it together with your other medications — always leave a gap of at least 2 hours.

Common Side Effects

Constipation (hard stool or difficulty passing stool)
diarrhea or loose stool
nausea
stomach cramps
chalky taste in the mouth

Serious Side Effects

Severe constipation that does not go away or stomach swelling — see a doctor immediately. Muscle weakness
confusion
or unusual tiredness (this can happen if you use it excessively for a long time due to aluminum or magnesium buildup). Black or tarry stools — go to the hospital right away.

Drug Interactions

Do not take this medicine at the same time as tetracycline, ciprofloxacin, or other antibiotics — antacids can stop them from working properly. Wait at least 2 hours between taking this antacid and any other medicine. It can also reduce the effectiveness of iron supplements, so space them apart.

Who Should NOT Take This

People with severe constipation or bowel obstruction should also avoid it. Not suitable for very young children without a doctor's advice.

How to Store

Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot, so avoid leaving it in a car or near a window. Keep the container tightly closed to protect from humidity. Always keep out of reach of children.
