Application of Ranitidine

Make sure to inform your doctor if you are allergic to any kind of medication. Liver and kidney problems or porhyria should also be reported to the doctor.

Use the medication exactly as doctor has prescribed it. Ranitidine tablets and effervescent tablets are meant to be dissolved in water and then taken. The medication needs time to heal the ulcers sometimes up to two months. After 6 weeks of treatment if your condition stays the same you should consult the doctor.

Avoid alcohol, because it may increase the risk of stomach problems.

In rare cases use of Ranitidine might increase the risk of pneumonia.

Sometimes early symptoms of a heart attack are mistaken for heartburn. Immediately call for medical attention if you happen to experience chest pain, dizziness, pain spreading to your left arm, shoulder or neck, sweating, nausea and vomiting, because these symptoms may be related to the heart attack.
