Phenergan contains Promethazine.

Product Overview

Phenergan is a medication containing the active ingredient Promethazine 10 mg. It is available in tablet form and is commonly used to manage various conditions, including allergies, motion sickness, nausea, and vomiting. Promethazine, the active ingredient in Phenergan, is an antihistamine that blocks the effects of histamine in the body, thereby alleviating allergic symptoms. Additionally, it has antiemetic properties, making it effective in reducing nausea and vomiting.


Phenergan tablets are utilized for the treatment of allergic conditions such as hay fever, allergic rhinitis, and hives. They are also prescribed to prevent and relieve motion sickness and to manage nausea and vomiting associated with surgery, anesthesia, or certain medical conditions. Furthermore, Phenergan may be used in combination with other medications to enhance their effectiveness in treating specific symptoms.

How to Use

Phenergan tablets should be taken orally with a full glass of water, with or without food. Follow the dosage instructions provided by your healthcare provider or as directed on the product label. Do not crush or chew the tablets, as this may interfere with their controlled-release mechanism. If you are using Phenergan to prevent motion sickness, take the medication at least 30 to 60 minutes before travel.

How it Works

Promethazine, the active ingredient in Phenergan, works by blocking the action of histamine at H1 receptors, thereby reducing allergic symptoms such as itching, sneezing, and runny nose. Additionally, it acts on the brain to inhibit the release of dopamine, a neurotransmitter involved in the regulation of nausea and vomiting. By blocking dopamine receptors in the brain, Promethazine helps alleviate symptoms of motion sickness and nausea.

Dosage and Administration

The dosage of Phenergan varies depending on the age, weight, and medical condition of the individual. It is typically taken 1 to 4 times daily as prescribed by your healthcare provider. Follow the instructions carefully and do not exceed the recommended dosage. For motion sickness prevention, take Phenergan 30 to 60 minutes before travel. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule.


Phenergan offers several benefits, including:

  • Relief from allergic symptoms such as itching, sneezing, and runny nose
  • Prevention and treatment of motion sickness
  • Reduction of nausea and vomiting associated with various causes
  • Convenient oral administration in tablet form

Common Side Effects

Common side effects of Phenergan may include drowsiness, dizziness, dry mouth, blurred vision, constipation, and urinary retention. These side effects are usually mild and temporary, but if they persist or worsen, contact your healthcare provider for further guidance. Avoid activities that require mental alertness, such as driving or operating heavy machinery, until you know how Phenergan affects you.


Phenergan should be used with caution in individuals with certain medical conditions, including asthma, chronic respiratory disorders, and liver disease. It may interact with other medications, such as sedatives, tranquilizers, and monoamine oxidase inhibitors (MAOIs), so inform your healthcare provider about all medications you are currently taking. Avoid alcohol consumption while taking Phenergan, as it may increase the risk of side effects such as drowsiness and dizziness.
