Summary
Paracetamol is used to relieve mild to moderate pain, which means discomfort or soreness, and to reduce fever, which is an elevated body temperature. Promethazine is used to treat allergy symptoms, which are reactions like sneezing and itching caused by allergens, nausea, which is the feeling of wanting to vomit, and motion sickness, which is dizziness or nausea caused by movement.
Paracetamol works by inhibiting the production of prostaglandins, which are chemicals in the body that cause pain and inflammation, meaning swelling and redness. Promethazine works by blocking histamine receptors, which are parts of cells that react to allergens, helping to reduce allergy symptoms and nausea. It also has sedative properties, which means it can make you feel sleepy, helping with motion sickness.
For Paracetamol, the typical dose is 500 mg to 1,000 mg every 4 to 6 hours, with a maximum of 4,000 mg per day. Promethazine is usually taken as 25 mg every 4 to 6 hours as needed, not exceeding 100 mg per day. Both medications are taken orally, which means by mouth, and should be used as directed by a healthcare provider.
Paracetamol is generally well-tolerated, but overuse can lead to liver damage, which is harm to the liver, an organ that processes toxins. Promethazine can cause drowsiness, which means feeling sleepy, dizziness, which is feeling unsteady, and dry mouth, which is a lack of saliva. Severe side effects can include allergic reactions and respiratory depression, which is slowed breathing.
Promethazine should not be used in children under two years due to the risk of severe respiratory depression, which is dangerously slow breathing. It should be used cautiously in people with respiratory issues or glaucoma, which is increased pressure in the eye. Paracetamol should be used with caution in individuals with liver disease or those who consume alcohol regularly, as it can affect liver function. Both medications should be used as directed to avoid serious side effects.
Indications and Purpose
How does combination of Paracetamol and Promethazine work?
