What is Phenergan and How Does It Work?
Phenergan contains the active ingredient promethazine hydrochloride. It is a sedating antihistamine. Unlike non-drowsy allergy medications, Phenergan enters the central nervous system. This lets it treat a wide range of symptoms beyond simple allergies.
By blocking histamine receptors, Phenergan manages allergic reactions like hay fever and hives.
Its action on the brain also makes it effective for nausea, motion sickness, and short-term insomnia.
Both Phenergan 25 mg tablets and Phenergan elixir 5 mg/5 ml are now available through online consultation with Prescriptsy.

How to Take Phenergan Properly
Your dose depends on the condition being treated. Your doctor gives specific instructions during the consultation.
Phenergan 25 mg (56 Tablets)
For allergies, adults usually take one 25 mg tablet at night, or 10-20 mg two to three times daily. For short-term insomnia, take one 25 mg dose before bedtime. Swallow tablets whole with water.
Phenergan Elixir 5 mg/5 ml (100 ml)
The elixir suits those who prefer liquid medication. For motion sickness, take the dose the night before travel or 1-2 hours before. Use a measuring spoon or oral syringe for accurate dosing.
Possible Side Effects
Phenergan must be used with care due to its sedative effects.
Common Side Effects
- Drowsiness or dizziness (very common; may last the next day)
- Dry mouth or blurred vision
- Headaches or restlessness
- Sensitivity to sunlight
Important Precautions
Drowsiness: Do not drive or use heavy machinery until you know how it affects you.
Alcohol: Avoid alcohol while taking Phenergan. It dangerously increases sedation.
Medical History: Phenergan may not suit those with asthma, glaucoma, or prostate enlargement. Not for children under 2 or pregnant/breastfeeding women unless a doctor advises.
Medical information
Phenergan contains promethazine hydrochloride, a first-generation sedating antihistamine with multiple therapeutic applications. It blocks central and peripheral H1 receptors and also has anticholinergic, antiemetic, and sedative properties.
Phenergan is used for the short-term treatment of insomnia, the symptomatic relief of allergic conditions including urticaria and hay fever, and the prevention and treatment of nausea and vomiting — including motion sickness and postoperative nausea.
Because promethazine causes significant sedation, it should be used with caution in patients who need to remain alert, and it is not recommended for children under 6 years.
A prescriber must assess the specific indication, check for interactions with other CNS depressants, and confirm that a sedating antihistamine is the most appropriate approach for your symptoms.
