Aluminium Hydroxide – What It Is and How It Works

Aluminium hydroxide is an over‑the‑counter antacid that neutralizes stomach acid. It’s often found in chewable tablets or liquid suspensions. When you take it, the compound reacts with gastric acid to form harmless aluminum salts, which reduces the burning feeling in your chest.

When to Use Aluminium Hydroxide

If you get occasional heartburn, sour stomach, or mild ulcer discomfort, aluminium hydroxide can help. It’s especially useful for people who need a gentle antacid that won’t cause jittery feelings like some calcium‑based products. You might also see it combined with magnesium hydroxide in dual‑action formulas; the magnesium balances out the constipation risk of aluminum.

Typical adult dosing is 500 mg to 1 g after meals, up to four times a day. Children’s doses are lower – usually about half the adult amount, but always check the label or ask a pharmacist. Don’t use it if you have a known allergy to aluminum compounds.

Safety Tips and Common Side Effects

The main side effect of aluminium hydroxide is constipation. If you notice hard stools, drink more water and add fiber to your diet. Some people experience a chalky taste in their mouth; that’s normal and goes away after a few minutes.

A rare but serious issue is aluminum buildup in the body, which can affect bone health or kidney function. This usually only happens with long‑term high‑dose use, especially in people with kidney problems. If you have chronic kidney disease, talk to your doctor before using any aluminum‑based antacid.

Always read the product label for warnings about drug interactions. Aluminium hydroxide can reduce the absorption of certain antibiotics (like tetracyclines) and iron supplements. Space those medications at least two hours apart from the antacid.

If you’re pregnant or breastfeeding, aluminium hydroxide is generally considered safe, but a quick chat with your healthcare provider never hurts.

In short, aluminium hydroxide offers fast relief for occasional acid upset without the buzz of caffeine‑type ingredients. Use it as directed, stay hydrated, and keep an eye on any changes in bowel habits. When you follow these simple steps, you’ll get the comfort you need while keeping side effects to a minimum.
