What doxycycline does

Doxycycline belongs to the tetracycline family. Bacteria need a steady supply of new proteins to grow and divide, and doxycycline attaches to the ribosome, the structure that assembles them, and stops production. The bacteria stop multiplying, and the immune system clears the rest. That makes it bacteriostatic, meaning it holds an infection in check instead of bursting the bacteria outright.

The same action covers a wide range of bacteria, which explains the variety of reasons people buy it. Chest infections, urinary infections, gum disease, tick-borne illnesses such as Lyme disease, and chlamydia are all in its remit. Dermatologists use it for inflamed acne and for rosacea, where it also calms inflammation. Doxycycline is one of the standard choices for malaria prevention on trips to affected regions.

The two listings

Both products are 100mg tablets, so the choice comes down to name. Doxycycline tablets are sold under the ingredient name, and Vibramycin carries the brand name. Each is listed for bacterial infections and acne.

Using it

Courses vary from a few days for an acute infection to several weeks or months for acne. Whatever the length, each tablet is swallowed whole with a full glass of water, sitting or standing, because one that lodges in the oesophagus (the gullet) can burn it. Dairy foods, calcium or magnesium antacids, iron and zinc supplements all interfere with absorption, so keep them apart.

What to watch for

Sun sensitivity is the side effect people most often forget, and it can cause a sunburn-like rash on skin exposed for even a short time. Bowel inflammation, signalled by watery or bloody diarrhoea, and raised pressure inside the skull, signalled by a persistent headache with blurred vision, are rare but need prompt treatment. A known tetracycline allergy rules it out, and the teeth of children and unborn babies can be stained, which is why it is kept from under-12s and from pregnancy.

Doxycycline can also change how blood-thinning warfarin behaves and should not be combined with oral retinoids such as isotretinoin. Keep the tablets cool and dry. The pack you pick is a matter of convenience: the 100mg tablet is the same in either listing, and a course is simply a number of those tablets taken at regular times each day.

Is Doxycycline available to order in Hong Kong?

You can order Doxycycline online with delivery to Hong Kong. The range is Doxycycline tablets and generic Vibramycin, both 100mg tablets. 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.

How much do Doxycycline products cost in Hong Kong?

Each of the two doxycycline products has its own price per pack, shown on its page in HKD or your selected currency; larger packs usually cost less per unit.

Do I need a prescription to order Doxycycline?

PockDose does not ask you to upload a prescription when you order doxycycline. See the ordering FAQ for details.

What are the brand names for doxycycline?

Vibramycin is a brand name of doxycycline, which is also sold as Oracea, Adoxa, Periostat and Doxt. Here, doxycycline can be bought online as generic Vibramycin and doxycycline tablets. These are generics, not the original brand.

Is Vibramycin the same as doxycycline?

Yes. Vibramycin is a brand name for doxycycline, so both listings contain doxycycline at 100mg. What differs is the name on the pack, and each can be ordered separately.

What is doxycycline used for besides acne?

It treats a long list of bacterial infections, among them chest, urinary, gum and some sexually transmitted infections, and tick-borne diseases like Lyme disease. Rosacea and malaria prevention are two further uses.

Why should I stay upright after taking doxycycline?

The tablet can irritate or ulcerate the gullet if it stalls on its way to the stomach. Swallowing it whole with a full glass of water and staying upright for at least 30 minutes lets it pass through.

Does doxycycline stop working if taken with food?

No. Food does not block it, and a snack can settle the stomach. The things to separate from your dose are dairy, antacids, iron and calcium supplements, which bind to the antibiotic and reduce how much you absorb.
