How effective Is Ranitidine?

Ranitidine is an effective way of managing and controlling symptoms such as heartburn, indigestions and stomach ulcers. It is a fast-acting treatment that offers relief within one or two hours upon ingestion. The effect lasts for 12 hours, but you are advised to follow the doctor's instructions since this is a prescription-only medication. Ranitidine takes a few weeks to work effectively.

How does Ranitidine work?

Ranitidine belongs to a class of medications known as H2 receptors. It works by blocking the H2 receptors – found in the stomach lining - from producing excess stomach acid, thus addressing symptoms such as acid aspiration during labour, or surgery, recurrent bleeding from peptic ulcers and bleeding from stress ulceration in people who are critically ill.

Ranitidine tames the backflow of acid into the oesophagus preventing heartburn symptoms and damage to the oesophagus. It also reduces the amount of stomach acid that flows into the duodenum allowing peptic ulcers to heal and preventing recurrent bleeding.

What dose should I choose?

Ranitidine is available in different strengths, and only Ranitidine 75mg is available over the counter without a prescription. It is suitable for persons over 16 years and adults.

Otherwise, other Ranitidine treatments require a prescription, and the dosage should be taken as per the doctor's instructions.

How should I take Ranitidine

Follow the doctor’s prescription while taking this medicine.  Swallow each tablet whole and with water. 

Usually, the dose prescribed will depend on your condition. From children over the age of 12 years to adults, the prescribed dose is 150 mg twice a day, in the morning/evening, or 300 mg at bedtime.

The doctor works out the right dosage based on your prescription.

Nevertheless, do not forget to read instructions for best use.

Side effects

The main side effect of using this medication may be a stomach upset or diarrhoea, as Ranitidine contains castor oil.

However, if you notice side effects such as itching or hives on the skin, swelling of the lips, face, tongue or any other parts of the body, shortness of breath, wheezing, chest pains, trouble breathing, fever or feeling weak when standing up, notify your doctor immediately. These are all signs of an adverse reaction towards the medicine, and you may be allergic to the ingredients in the product. 

This medication may also affect your kidneys by changing the amount and colour of the water you pass. This could lead to pain when passing urine, blood in urine, fever, back pain and changes in blood tests. 

In the same way, Ranitidine may cause side effects such as severe stomach pain (pancreatitis), slow or irregular heartbeat, stomach pain, nausea, constipation, skin rash, changes to liver functions and other rare side effects that maybe detected in blood tests.

Therefore if ever you experience any of the listed side effects, including those not indicated on your leaflet, seek immediate help from your GP or hospital. 

You are also welcome to consult our specialists at Click Pharmacy should you require any further advice.
