Ranitidine is a drug classified among H2 antagonists and works by preventing the production of gastric acid. It is marketed under different names, depending on the laboratory that makes them and is usually over the counter, but this may change depending on the country where you are and the dose you need. Ranitidine is taken orally, it can be tablets, effervescent or syrup, it should be noted that it is not recommended to take ranitidine without medical supervision for more than two weeks. At FastlyHealwe show you what ranitidine is for and the recommended dose .

What is ranitidine for

Ranitidine is used to treat ulcers, gastroesophageal reflux , a condition in which there is a sensation of hot liquid that travels through the esophagus and can even reach the mouth and produce a sour taste. It is also used to treat lesions in the esophagus and for stomach conditions in which too much acid is produced. Ranitidine over-the-counter is generally used as a preventive measure and to treat heartburn symptoms by reducing the amount of acid the stomach produces during digestion.

Another use of ranitidine is to treat bleeding in the digestive tract, to prevent ulcers caused by stress, or to treat damage caused by the consumption of non-steroidal anti-inflammatory drugs (NSAIDs).

Recommended dose

The recommended dose of ranitidine will depend on the condition to be treated:

  • Ulcers : take 150 mg twice a day or 300 mg once a day at night for up to 6 weeks.
  • Gastroesophageal reflux : 150 mg twice a day or 300 mg at night, for up to 12 weeks. If the condition is moderate to severe, 150 mg 4 times a day is recommended.
  • Esophageal hemorrhages : 50 mg every 6 or 8 hours

It should be noted that these doses must be supervised by a specialist and the recommendation is to take it between 30 or 60 minutes before eating foods that may cause heartburn . In the case of children, the dose will depend on the ailment and the kilograms that it weighs. If you are a dialysis patient, the recommended dose is 150 mg per day, after dialysis . On the other hand, if you forgot to take the medicine, take it as soon as possible. If it’s time for your next feed, skip the one you missed , but never take a double dose .
