Product Information

Phenergan Oral Solution contains promethazine hydrochloride, an antihistamine that helps relieve allergic reactions, hay fever, itchy skin rashes (such as hives), and travel sickness. It also has calming properties that can ease restlessness, nausea, or mild trouble sleeping caused by allergies or discomfort. Each 5 ml contains 5 mg of promethazine hydrochloride.

How Phenergan Works

This oral solution performs a dual action to manage your symptoms effectively:

  • Allergy Relief: It blocks histamine, a natural substance your body produces during an allergic reaction, to treat hay fever and skin rashes like hives or nettle rash.  
  • Nausea Prevention: It works directly on the brain to help you feel more relaxed and prevent vomiting, making it highly effective for travel sickness

Pharmacist Advice

At Inish Pharmacy, our pharmacists can recommend Phenergan for the short-term relief of allergy symptoms and travel sickness in adults and children aged 6 years and over.
Because Phenergan can cause drowsiness, it’s best taken at night if used for allergies, or before travel to prevent motion sickness.

How to use

How to Take Phenergan

For your safety, always follow the recommended dosage and do not exceed the stated dose or use for more than 7 days without pharmacist or GP advice. Use a medicinal 5ml spoonful for accurate measurement.

For Allergic Conditions (Hay Fever, Rashes, Hives):

  • Adults (including Elderly): 25mg (five 5ml spoonfuls) once a day at bedtime. This may be increased to a maximum of 25mg three times a day if required.
  • Children (6–10 years): A single dose of 10mg–25mg (two to five 5ml spoonfuls) at bedtime, OR 5mg–10mg (one to two 5ml spoonfuls) twice a day. The maximum daily dose for this age group is 25mg.

For Travel Sickness (Prevention of Nausea/Vomiting):

  • Adults (including Elderly): 25mg (five 5ml spoonfuls) taken the night before the journey. This can be repeated after 6–8 hours if required.
  • Children (6–10 years): 10mg (two 5ml spoonfuls) taken the night before the journey. This can be repeated after 6–8 hours if required.

Who Should Not Take Phenergan

Do not take Phenergan if you or your child:

  • Are under 6 years of age.
  • Are allergic to promethazine or any listed ingredients.
  • Have taken MAOIs (antidepressants) within the past 14 days.
  • Have asthma, epilepsy, heart problems, or severe liver/kidney disease.
  • Are pregnant or breastfeeding, unless your doctor advises otherwise.

Avoid alcohol while taking Phenergan as it can increase drowsiness.

Possible Side Effects

Most people tolerate Phenergan well when used correctly.
Common side effects include:

  • Drowsiness or dizziness
  • Dry mouth or blurred vision
  • Constipation or mild stomach upset

Serious but rare effects include:

  • Allergic reactions (rash, swelling, difficulty breathing)
  • Irregular heartbeat or yellowing of the skin/eyes (liver problems)

Avoid driving or operating machinery if drowsy, and avoid prolonged sun exposure, as Phenergan can make skin more sensitive to sunlight.
