Guaifenesin thins the mucus behind a chesty cough so it is easier to cough up, and the range here carries Bro-Zedex Syrup, a 100ml bottle with three other ingredients.
Bromhexine, Guaifenesin, Menthol, Terbutaline
100ml
Bro-Zedex Syrup is a 100ml liquid cough medicine combining bromhexine, guaifenesin, menthol and terbutaline, used for chesty coughs, bronchitis and wheezing.
A cough that brings up phlegm is doing a job: clearing the airways. Thick mucus makes that job slow and tiring, and guaifenesin is the ingredient that thins it. It is an expectorant, which means it loosens what is sitting in the air passages so a cough can shift it. It eases congestion rather than treating whatever is behind it, and it does not shorten a cold or chest infection. Wet, chesty coughs suit it; dry, tickly ones do not.
Guaifenesin is swallowed, with or without food. Ordinary tablets, capsules and syrups are usually taken about every four hours as needed; long-acting tablets go twice a day and are swallowed whole — breaking or chewing one releases the medicine too quickly. A syrup is measured in millilitres, so use the cup or spoon that came with the bottle rather than a kitchen spoon. Water matters here — thin, well-hydrated mucus is easier to cough up, which is the whole point.
You will find it on its own and in cough and cold combinations, next to a suppressant, a decongestant, an antihistamine or — as in this range — three other ingredients. Two combination products at once can double up on the same ingredient, so one is enough. Bro-Zedex Syrup is a 100ml bottle that pairs guaifenesin with bromhexine, menthol and terbutaline: bromhexine breaks mucus down further, menthol leaves a cooling feel in the throat, and terbutaline opens the bronchial airways. It suits a productive cough, bronchitis and wheezing — a chesty cough with tightness or a wheeze, in other words. Bro-Zedex sits in the shop's asthma and respiratory care group.
On its own, guaifenesin seldom causes problems; an upset stomach, nausea or vomiting turn up occasionally, and so do headache and dizziness. The syrup in this range has more going on, because terbutaline can make the hands shake and the heart beat faster, with palpitations. If a rash, itching or swelling appears after a dose, one of the ingredients is the likely cause.
Store it in a cool, dry spot away from direct sunlight, with the cap screwed tight and out of children's reach. Keep the measuring cup with the bottle, so every dose is measured the same way.
You can order guaifenesin online with delivery to Hong Kong. The range has Bro-Zedex Syrup, a 100ml bottle that combines guaifenesin with bromhexine, menthol and terbutaline. A parcel that does not arrive within the delivery window, or arrives damaged, is sent again free, and if that is not possible the order is refunded.
Bro-Zedex Syrup is priced per pack: its page lists every strength and pack size with the current price in HKD or your chosen currency.
PockDose does not ask you to upload a prescription when you order guaifenesin. See the ordering FAQ for details.
Read the ingredient list on each bottle first. Guaifenesin sits in a great many cough and cold products, so two of them together can quietly double the dose. A second bottle that lists it too adds nothing new.
No — it is not a cough suppressant. Guaifenesin works on the mucus, thinning it so the cough can clear your chest instead of hacking at nothing. A dry cough with no phlegm is a different problem, and that one is usually handled with a suppressant rather than an expectorant.
Cough and cold combination products that contain guaifenesin are not given to children under 4 years of age. For older children the amount depends on the product and the child's age, so the pack's own instructions are the ones to go by rather than an adult dose scaled down.
They are different ingredients that both work on chest mucus. Guaifenesin thins secretions so they are easier to cough up; bromhexine is a mucolytic, breaking the mucus down and making it less sticky. Bro-Zedex Syrup contains both, along with menthol and terbutaline.
