According to the NHS, liquid paraffin is used as a treatment for constipation as it softens the stools and lubricates the bowel to help it pass. It is taken orally in a liquid form and should not be taken repeatedly or for long periods of time.
One should always consult a physician before taking liquid paraffin if the patient is under 3 years old or is suffering from stomach pain, nausea, vomiting or problems swallowing.A physician should also be consulted if the patient needs vitamin K supplements or is taking anticoagulants. The patient should not take the medication if the person is pregnant, is trying to become pregnant or is breastfeeding. One should be careful not to inhale the liquid as this can bring on pneumonia in some patients.
