Promethazine Cough Syrup Review: How Much Is Effective?

promethazine cough syrup

Promethazine was made in the 1940s by scientists working at Rhône-Poulenc laboratories. In 1951, this medication was approved in the U.S. By 2019, and Promethazine became the 174th most commonly prescribed medicine in the U.S. after reaching 3 million prescriptions.

Promethazine belongs to the class of drugs called phenothiazine. Promethazine is an antihistamine used with other medications to treat anaphylaxis (sudden, severe allergic responses) and cold symptoms like sneezing, coughing, and runny nose.
Patients are also sedated and relaxed with Promethazine before and after surgery, during childbirth, and other times.

How Does Promethazine Cough Syrup Work?

Promethazine works by blocking some cells in your body from releasing a chemical called histamine. Histamine is regularly released when you’re allergic to something, such as pollen, dander, mold, or chemicals.

This medicine promotes drowsiness and aids in pain management by blocking histamine production. This is since histamine aids in the regulation of wakefulness, keeping you aware and your senses heightened.

This medication also works to lessen the activation of the portion of your brain that causes you to vomit.

What Does Promethazine Treats?

Promethazine Cough Syrup works as medication for flu, allergies, common cold, and other respiratory disorders (e.g., sinusitis, bronchitis). Promethazine, an antihistamine, watery eyes, itchy eyes, runny nose, and sneezing are all relieved.
Discuss the risks and advantages of this drug with your doctor.

Study On Its Effectiveness:

According to the National Institutes of Health (N.I.H.). Promethazine is a histamine receptor antagonist. Histamine receptors are proteins that bind to histamine to trigger allergic reactions. As a result, Promethazine is a powerful antihistamine.
The medication also inhibits cholinergic receptors, effective for nausea, morning sickness, and cough prevention and treatment.
Promethazine can only aid with symptom management. It’s ineffective in treating the underlying source of symptoms or accelerating recovery.

Precautions:

  • If you’re 65 or older, talk to your doctor about the risks and advantages of taking Promethazine. Promethazine is not recommended for usage by older adults since it is not as safe as alternative drugs that can be used to treat the same symptoms.
