Summary: This article breaks down exactly how to use Gaviscon for maximum relief from heartburn and acid reflux. Drawing on hands-on experience, user feedback, and medical guidance, I’ll share step-by-step instructions (and some honest mistakes I’ve made), plus what you need to know about timing, food, and even common misconceptions. You’ll also see references to expert opinions and regulatory guidance. If you’re tired of generic instructions, this is for you.
Gaviscon is widely used to treat symptoms of acid reflux, heartburn, and indigestion. If you’ve ever felt that annoying burn after a big meal or when lying down, you know what I’m talking about. What makes Gaviscon different is that it doesn’t just neutralize stomach acid—it forms a physical barrier to stop acid from splashing up your esophagus. That’s the core promise, and when used right, it can make a night-and-day difference.
In fact, the UK’s National Health Service (NHS) specifically recommends Gaviscon for fast relief, and it’s available over-the-counter in most countries.
Here’s something that surprised me: Gaviscon works best when you take it after meals and before bedtime. That makes sense once you know that eating triggers stomach acid production, and lying down makes reflux worse. But I used to take it only when symptoms hit—turns out, that’s not optimal.
“For maximum benefit, take Gaviscon after meals and before going to bed.”

For adults and children over 12: The usual dose is 10–20 ml (2–4 teaspoons) of liquid or 2–4 tablets after meals and at bedtime. But always check the packaging for your specific product, because strengths and formulations vary.
My mistake #1: I once doubled the dose, thinking it would work faster. Don’t do that—more is not better, and it can cause side effects like bloating or diarrhea. Always follow the label or your doctor’s advice.
Here’s how I actually take it (using the liquid version):
