Ranitidine to reduce stomach acid

Zantac

Nota dell'autore clinico Michael Stewart 18/5/2024: Further to earlier notes, all ranitidine products have now been discontinued in the UK. At the time of review there are no branded or generic products containing ranitidine available in the UK. Ranitidine may still be available in other countries. This medicine leaflet is based on medical information available in the UK at the time of writing and is left here for reference purposes. Please also refer to the manufacturer's information supplied with your medicine.

Nota dell'autore clinico Michael Stewart 22/02/23: As a precautionary measure all ranitidine-containing products have been discontinued globally whilst the scientific investigation into its risks and benefits is ongoing. It is not known whether ranitidine products will be made available again in the future. If you have any concerns regarding your use of ranitidine please speak to your doctor or a pharmacist.

Nota dell'autore clinico Michael Stewart 21/11/2019: Since October 2019 a large number of ranitidine products have been recalled by their manufacturers. Pharmacies and other retailers have been told to remove these products from sale. The recalls are due to a risk of contamination with a potentially harmful chemical. There may be an ongoing shortage of ranitidine products as a consequence. If you have any concerns about the medicine you are taking you should speak with your pharmacist for advice.

Ranitidine reduces the amount of acid produced by your stomach.

Ranitidine belongs to a group of medicines that reduce the amount of acid produced by the cells in the lining of the stomach. They are called 'histamine H2-receptor antagonists', but are commonly also called Bloccanti H2.

Ranitidine is helpful in the treatment of conditions caused by too much acid being produced in the stomach. These conditions include ulcere gastriche (ulcere dello stomaco), ulcers of the upper part of the intestine (duodenal ulcers), acid reflux or heartburn (reflux oesophagitis), and indigestione. Ranitidine is also prescribed to treat ulceration of the stomach which has been caused by farmaci antinfiammatori non steroidei (FANS).

Acid is produced naturally in your stomach to help you digest food. Excessive amounts of acid can irritate the lining of your stomach, causing inflammation, ulcers and other conditions. Ranitidine works by reducing the amount of acid produced by your stomach. This helps to relieve symptoms and assist the healing process where damage has already occurred.

Ranitidine is available on prescription. You can also buy short courses of ranitidine at retail outlets for symptoms such as heartburn, indigestion and hyperacidity in adults and in children over 16 years of age.

To make sure that this is the right treatment for you, before you start taking ranitidine it is important that you speak with a doctor or pharmacist:

  • Se sei incinta o stai allattando.

  • If you have any of the following symptoms: difficulty swallowing, loss of blood, or weight loss, or if you are being sick.

  • Se hai problemi con il funzionamento dei tuoi reni.

  • Se hai un raro disturbo ereditario del sangue chiamato porfiria.

  • Se hai mai avuto una reazione allergica a un medicinale.

  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about ranitidine and will provide you with a full list of the side-effects which you may experience from taking it.

  • Take ranitidine exactly as your doctor tells you to, or as directed on the label if you have bought it. There are three different strengths of tablet available - 75 mg, 150 mg and 300 mg. Only the lower strength of tablet can be purchased. Ranitidine is taken once or twice a day.

  • You can take ranitidine either before or after meals.

  • If you forget to take a dose at your usual time, you can take it when you remember. However, if it is nearly time to take your next dose when you remember, leave out the missed dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

  • A course of treatment can vary in length depending upon the reason why you are taking ranitidine. It may be just for a few days to relieve your symptoms, or for several weeks to help an ulcer heal. Keep any appointments that you have booked with your doctor so that your progress can be checked.

  • Some people say that certain foods make their symptoms worse. Foods and drinks that have been suspected of this include peppermint, tomatoes, chocolate, spicy foods, hot drinks, coffee, and alcoholic drinks. If it seems that a food is aggravating your symptoms, try avoiding it for a while to see if your symptoms improve. Also, try avoiding eating large meals, as these can make your symptoms worse too.

  • Se sei in sovrappeso, questo mette ulteriore pressione sullo stomaco e favorisce i sintomi del reflusso acido. Perdere un po' di peso e seguire una dieta sana ed equilibrata potrebbe aiutarti.

  • Smoking increases the amount of acid produced by the stomach and may make your symptoms worse. If you are a smoker, speak with your doctor or pharmacist about how to quit.
