Some lower strengths of Ranitidine tablets are available to buy over the counter in the UK. The 150mg Ranitidine tablets contained in the Anytime Doctor Travel Pack® are prescription only medication, which means that they are not available to buy over the counter.

You should usually start to get relief from acid reflux within 1-2 hours of taking Ranitidine tablets. Effects can last up to 12 hours. Do not take another dose if your symptoms have not improved. Instead get medical help, as this could be a sign that something else is causing your symptoms.

Stress itself doesn’t cause heartburn or acid reflux, but it can lead sufferers of heartburn to do things that can increase their stomach acid production. This can include smoking, drinking more caffeine, eating high-fat foods, or eating late at night.

Heartburn is a common symptom of reflux, the medical term for when the contents of your stomach come back up into your oesophagus (food pipe). Heartburn is the feeling of burning in your chest.

Ranitidine is an H2 receptor antagonist, not an antacid. It works by reducing the amount of stomach acid produced. Antacids work by neutralising the acid produced by your stomach. Antacids can usually be bought over the counter and include brands such as Gaviscon, Rennie and Pepto-Bismol.
