FAQ
What bottle sizes of Phenergan Syrup can I order?
Phenergan Syrup comes as generic promethazine in 100ml bottles, in packs of 1, 2, 3, 4 or 5 bottles. This is generic promethazine, not the original Phenergan Syrup. Larger packs cost less per bottle.
How does Phenergan Syrup reach Hong Kong?
Phenergan Syrup is sent to Hong Kong by tracked courier in 5 to 9 business days with online tracking, or by standard airmail in 14 to 21 business days, up to 30, untracked. Bottles arrive in plain, unbranded packaging with nothing on the outside about the contents.
What other names is promethazine sold under?
Phenergan is a brand name of promethazine, which is also sold as Sominex. Here, promethazine can be bought online as generic Phenergan Syrup. These are generics, not the original brand.
Does Phenergan Syrup make you sleepy?
Yes. Promethazine is one of the sedating antihistamines, so drowsiness is expected rather than something that only some people get. It is strongest in the hours after a dose and can leave you groggy the next morning, which is why a night-time dose suits most people.
Can I drink alcohol with Phenergan Syrup?
No. Alcohol and promethazine both slow the brain down, so together they bring heavier drowsiness, dizziness and clumsiness than either would alone. Even a small drink can add to the effect, so it is simplest to leave alcohol out while you are using the syrup.
How is Phenergan Syrup different from Phenergan tablets?
They contain the same active ingredient, promethazine. The tablets are 10mg and 25mg and swallowed whole; the syrup is a 100ml liquid measured out by spoon or cup. A liquid is easier to take in smaller measured amounts and suits anyone who dislikes swallowing tablets.
Can children take Phenergan Syrup?
Not under the age of 6 — promethazine products are not used in younger children. For older children it is given for allergies and as a calming sedative, usually as one dose in the evening, since sleepiness is the main effect. The amount given depends on the child's age.
When should I take Phenergan Syrup for travel sickness?
Take it before the journey starts, while you still feel well. Once queasiness has set in, a dose is harder to keep down and slower to help. The sleepiness is part of how it works, so plan for someone else to drive if the trip is a long one.
About Phenergan Syrup
What promethazine syrup is used for
Hay fever that keeps you awake, a rough ferry crossing, a child who will not swallow a tablet: a liquid antihistamine covers all three. Phenergan Syrup is promethazine in liquid form, one of the older phenothiazine antihistamines — the ones that calm the brain as well as block histamine. That is why it does two jobs at once, easing allergy symptoms and settling nausea.
It is used for allergic problems of the nose and skin — hay fever, a runny or itchy nose, hives, itchy rashes — and for vomiting and sickness, including travel sickness. Adults take it for short-term sleeplessness as well. Because it is strongly sedating, most people take their dose in the evening.
How to take Phenergan Syrup
For allergy symptoms a single dose at night is usual, with a second dose the next day if symptoms break through. For travel sickness, take it before you set off rather than waiting until you feel unwell; a queasy stomach will not hold it down.
Measure the dose with a proper measuring spoon or cup rather than a kitchen spoon, so the volume is right. The drowsiness can carry over into the next morning, so leave driving, cycling and machinery until you know how the syrup affects you. Alcohol adds to both the sedation and the dizziness, so it is worth leaving out while you are using it.
Side effects worth knowing about
Sleepiness is the commonest effect, and often the reason the syrup was chosen in the first place. Dry mouth, blurred vision, dizziness and constipation are also common. Some children become restless or irritable rather than sleepy.
Get help straight away if the lips, tongue or throat swell, if a rash comes with breathing trouble, or if the heartbeat feels fast or irregular. Rarely, promethazine brings on involuntary movements — the neck or eyes twisting, the tongue pushing forward — and these need prompt treatment.
Phenergan Syrup or Phenergan tablets?
Both are promethazine. Phenergan tablets come as 10mg and 25mg and are swallowed whole; the syrup is a 100ml bottle of liquid measured by spoon. If swallowing a tablet is the problem, the liquid is the practical choice, and tablets are easier to carry. The promethazine page covers the ingredient and the tablets.
