What is Rennie Deflatine and how does it work?

Rennie is well known for its fast relief from digestive discomfort such as indigestion, heartburn, and now trapped wind. Trapped wind affects many of us from time to time, and although the symptoms may be embarrassing to some, they can be easily treated with remedies such as Rennie Deflatine. This medicine contains a key ingredient known as simeticone which is an antiflatulent. It works by combining smaller gas bubbles - which can get trapped - to form larger bubbles which allows air to expel out of the body more easily and in turn, reduces bloating and feelings of fullness in the stomach.

Rennie Deflatine also contains antacids such as calcium carbonate and magnesium carbonate which help to relieve any heartburn or indigestion caused by excess stomach acid. This medicine helps to relieve overall discomfort in the digestive area.

How long does Rennie Deflatine take to work?

Antacids get to work straight away and simeticone starts to work within 30 minutes. Chewable tablets often get to work faster than those that are swallowed whole. In the meantime, try to avoid anything that may trigger or worsen your symptoms such as high fat, greasy, or spicy food which creates more gas in the digestive system. Knowing your triggers is also a good long term way of managing this condition.

How to take Rennie Deflatine tablets

Rennie Deflatine tablets can be sucked or chewed, the tablets are mint flavoured and sugar-free. It’s recommended that adults and children over 12 years old take 1 to 2 tablets to relieve symptoms, you can take up to 11 tablets a day but do not exceed this dose and do not take for longer than 14 days. However, if your symptoms are getting worse despite taking Rennie or your symptoms are still present after 2 weeks you should see your doctor for further diagnosis and treatment.

Who should not take Rennie Deflatine?

Some people may not be suitable for this medicine, including children under the age of 12 years, those who have kidney problems (speak to your doctor for advice), those who have high levels of calcium in the blood, or if you have an allergy or intolerance to the ingredients in this medicine. Speak to a doctor or pharmacist if you’re unsure about whether Rennie Deflatine is suitable for you.

Can I take Rennie Deflatine while pregnant or breastfeeding?

If you’re suffering from heartburn or indigestion associated with pregnancy, Rennie may be a suitable treatment, however, you should always speak to your doctor before taking any new medication if you are pregnant or breastfeeding.

Can I take other medicines with Rennie Deflatine?

Rennie Deflatine may affect certain medicines, speak to your doctor or pharmacist if you’re taking any of the following. Most of these medicines may be taken at least 1-2 hours before taking Rennie Delatine.

  • Digoxin
  • Thiazide diuretics
  • Fluorides
  • Phosphates

Are there any side effects?

It’s rare to experience side effects with Rennie Deflatine, but as with any medicine, people react differently. Side effects may occur with prolonged use, to avoid this do not take more than the recommended dose or for longer than 14 days without consulting with your doctor first. In very rare cases, side effects may be the result of an allergic reaction with symptoms such as a rash, swelling, or difficulty breathing, if you experience these symptoms or any other side effects stop taking this medicine and consult your doctor straight away. If you’re having a severe allergic reaction call 999 or visit your nearest A&E department urgently.
