What is Phenergan?

Phenergan, containing the active ingredient promethazine, is an antihistamine often used to promote sleep due to its sedative properties. It works by blocking certain receptors in the brain, not only alleviating allergy symptoms but also inducing a calming effect. This makes Phenergan particularly useful for individuals needing help with relaxation and managing sleep disturbances related to allergies. However, its strong sedative effects mean it should be used carefully under medical supervision to avoid impairing activities that require alertness.

What is the active ingredient in Phenergan?

The active ingredient is promethazine.

What is Phenergan used for?

Phenergan is used to address a variety of conditions including:
  • Treating allergic reactions like hay fever or rashes (such as nettle rash or hives)
  • Managing nausea or preventing vomiting, as may be experienced with motion sickness
  • For short-term relief of insomnia in adults
  • Temporarily as a sedative for children aged 6 years and older

How does Phenergan work?

Phenergan, which contains promethazine as its active ingredient, primarily functions as an antihistamine. It works by blocking histamine receptors in the brain and other parts of the body. Histamine is a chemical released during allergic reactions that contributes to inflammation, swelling, and the typical symptoms of an allergy like itching and runny nose.

In addition to its antihistamine properties, Phenergan affects other receptor systems in the body:

  • It blocks certain acetylcholine receptors, which helps reduce nausea and motion sickness.
  • It has sedative effects because it also influences the central nervous system, inducing a calming effect which can be beneficial for inducing sleep.

These actions make Phenergan effective not only in treating allergic reactions but also in managing conditions like insomnia, nausea, and motion sickness by calming and stabilizing bodily responses.

How do you use Phenergan?

Ensure that you always use this medication as instructed in the accompanying leaflet or as advised by your doctor or pharmacist. If you are uncertain, consult with your healthcare provider. The appropriate dosage of Phenergan Tablets depends on the reason for use. The guidelines below can help determine the necessary amount:

  • Do not use for more than 7 days.
  • If symptoms worsen or do not improve after 7 days, consult your doctor or pharmacist.

Does Phenergan interact with other medicines?

Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medications. This includes over-the-counter medicines and herbal supplements, as Phenergan Tablets can interact with other drugs, affecting how they work or how Phenergan works. Particularly important to mention are:

  • Monoamine Oxidase Inhibitors (MAOIs): Do not take Phenergan if you have used these antidepressants in the last two weeks.

If unsure, always consult your doctor or pharmacist. Also, notify your healthcare provider if you are using any of the following medications:

  • Anticholinergics: Often prescribed for conditions like irritable bowel syndrome, asthma, or a weak bladder. These may increase the risk of side effects like dizziness, dry mouth, and blurred vision.
  • Mental Health Medications: This includes antipsychotics (e.g., haloperidol, quetiapine) and antidepressants (e.g., amitriptyline, citalopram).
  • Sedatives or Relaxants: Such as diazepam or zolpidem, which are used to aid sleep or reduce anxiety.
  • Pain Management Medicines: Like aspirin, which is used for arthritis or joint pain. Phenergan may mask some of their side effects.
  • Antiarrhythmics: Medications like quinidine and amiodarone, used to manage irregular heartbeats.
  • Antiepileptics: Drugs used for controlling epilepsy or preventing seizures.
  • Antimicrobials: Such as erythromycin and levofloxacin, which are used to treat infections.

Discussing all current medications with your healthcare provider is crucial to prevent potential adverse interactions.
