What is Rennie®?

Many adults suffer from heartburn, indigestion and trapped wind at some point in their lives. Symptoms range from the pain or discomfort of acid indigestion (also known as dyspepsia) to the burning chest pain of heartburn and the bloated stomach and flatulence caused by trapped wind.

If you suffer from heartburn, indigestion or trapped wind, it's likely that the symptoms are triggered by what you eat, how you eat or a busy, stressful lifestyle. This website explains why these factors can cause digestive problems and the steps you can take to avoid them. It also contains information on the Rennie® range of fast-acting, effective treatments which help to relieve the pain and discomfort so you can get on with your life.

Is Rennie® safe?

Rennie® contains calcium carbonate and magnesium carbonate, two naturally occurring substances. Because Rennie® contains natural substances, it can be taken frequently, when heartburn or indigestion arises to help calm your tummy.

The usual dose is 1-2 tablets up to three times daily. This gives a maximum daily dose of 6 tablets.

Rennie® during pregnancy

Rennie doesn't rely on complicated chemical formulas to resolve your discomfort - simplicity is key.

All Rennie® products can be used during pregnancy if taken as instructed and if prolonged intake of high dosages is avoided.

Medicines can affect the unborn baby. Always talk to your doctor or pharmacist before taking any medicine during pregnancy.

The history of happy tummies

Rennie® has a long history of resolving stomach problems simply. Way back in the late 1920s John Rennie® had marketed his tablets in France as an aid to indigestion. They proved an immediate success.

In 1935, Harry Marland met John Rennie® in Leeds, England and bought a product from him. Convinced of the potential of this remedy, Harry Marland bought the rights from him for £5,000. When the two men parted, Harry Marland remarked to John Rennie®: “Just wait, one day your name will be on display in every local chemist.”

Harry Marland was right… On the eve of the Second World War, “Rennie®” tablets made their appearance on the British market.

In 1992, Nicholas Laboratories, holders of the Rennie® trademark, sold the brand to Swiss company F. Hoffmann-La Roche S.A.. Rennie® is now included in the brand portfolio of Bayer Consumer Care. Bayer extended the range and Rennie® now helps to relieve heartburn all over the world.

FAQ

Why can certain food and drinks cause heartburn?

Heartburn can be triggered by eating food that's difficult to digest because this will cause your stomach to produce more acid. Coffee, chocolate and alcohol are thought to be key causes of heartburn because they can make the valve between the oesophagus and the stomach relax, allowing stomach acid to leak back into the oesophagus.

Why can stress cause heartburn?

When you feel up tight or under stress, your body goes into 'fight or flight' mode, releasing adrenaline and diverting blood away from the stomach. As a result the muscles in the wall of your stomach contract less frequently and the digestive process becomes less effective. When your body realises that digestion is not happening properly it produces more stomach acid which can build up until there is an excess. If this stomach acid leaks into the oesophagus it can cause heartburn.

Why is heartburn common during pregnancy?

During pregnancy a woman's body produces the hormone, progesterone, which slows down digestion and causes the muscular valve between the oesophagus and the stomach to relax, increasing the risk of gastro-oesophageal reflux.

As a result stomach acid is more likely to leak into the oesophagus and cause heartburn. Also, as the baby grows, pressure on the stomach increases and this can force stomach acid into the oesophagus, again causing gastro-oesophageal reflux.

What is gastro-oesophageal reflux?

When you eat or drink something it passes down the oesophagus into the stomach. Gastro-oesophageal reflux occurs when the contents of your stomach travel back up into the oesophagus. Unlike vomiting, gastro-oesophageal reflux can happen without you realising.

Why does gastro-oesophageal reflux happen?

There is a ring of muscle at the lower end of the oesophagus which is there to stop gastro-oesophageal reflux. When you eat or drink something the muscle relaxes to allow the food or liquid to pass into your stomach. Then it tightens up again when you've finished. Gastro-oesophageal reflux happens if the muscle becomes slack or relaxes at the wrong time.

What is GORD?

GORD is short for Gastro-Oesophageal Reflux Disease, the name given to damage to the oesophagus caused by stomach acid as a result of gastro-oesophageal reflux.

What is GERD?

GERD - gastroesophageal reflux disease - is just another name for GORD

What is Reflux Oesophagitis?

Reflux Oesophagitis is the medical term for inflammation of the oesophagus caused by stomach acid as a result of gastro-oesophageal reflux.
