FAQ
Which NeoMercazole strengths and pack sizes can I order?
NeoMercazole comes as tablets in 5mg and 10mg strengths. You can order packs of 130 or 260 tablets. The pack contains generic carbimazole, not the original NeoMercazole. Larger packs cost less per tablet.
How is NeoMercazole delivered to Hong Kong?
NeoMercazole tablets go by standard airmail, taking 14 to 21 business days, or 30 at most, and are untracked. Every order ships in plain, unbranded packaging with nothing on the outside about the contents. If a parcel does not arrive within the delivery window, it is sent again free.
How long will I need to take NeoMercazole?
A course usually runs for months, often a year or more, and it continues well past the point where you feel normal again. The dose is trimmed as blood tests improve rather than stopped at the first good result, because thyroid levels can climb back up.
Can I drink alcohol while taking carbimazole?
There is no known interaction between carbimazole and alcohol, and a drink now and then is not a problem. Heavy drinking is a different matter: the shakes, sweats and racing pulse of a hangover are easily confused with an overactive thyroid, which makes it harder to tell what is working.
Is NeoMercazole the same as carbimazole?
NeoMercazole is one brand name for carbimazole, the active ingredient in these tablets, and other brands of the same medicine exist too. What matters when you order is the strength on the pack, because that is how much carbimazole each tablet holds.
Does carbimazole make you put on weight?
Weight often comes back once the thyroid is no longer overactive, so some gain is expected and it is not the tablets themselves doing it. Appetite settles at the same time, so the weight lost while the thyroid was overactive usually comes back.
About NeoMercazole
What NeoMercazole is used for
NeoMercazole is a brand of carbimazole, a tablet medicine that calms an overactive thyroid. Too much thyroid hormone speeds the whole body up: a thumping heartbeat, weight loss, sweating, shaky hands, feeling wired and short-tempered. Carbimazole brings hormone production back down. It is used for Graves' disease, the autoimmune form of an overactive thyroid, and to steady levels before thyroid surgery or while radioiodine treatment takes effect.
Carbimazole belongs to the thionamide family of antithyroid medicines. Inside the thyroid it blocks the step where iodine is joined onto the building blocks of thyroid hormone, so no new hormone is made while the tablets are working.
Taking your tablets
NeoMercazole comes as 5mg and 10mg tablets, swallowed whole with water. Most people take one dose a day, and a fixed time keeps the amount in the body steady. Food makes no difference, so a dose can go with breakfast or between meals.
The starting dose is usually higher than the maintenance dose, and it is often split into two doses a day. As blood tests show hormone levels falling, the amount comes down; tests every few weeks check thyroid hormone levels and the blood count.
If a dose slips your mind, take it later the same day; when the next one is nearly due, leave the missed dose out rather than taking two together.
How soon it starts to work
The tablets stop new hormone being made, but they cannot clear what is already stored in the gland, so the first days often feel no different. Symptoms usually start to ease over a couple of weeks, and blood levels take several weeks to settle.
Side effects to watch for
Sick feelings, headache, an itchy rash, aching joints and a strange taste in the mouth are the complaints that turn up most, and they often fade as the body adjusts. A sore throat, mouth ulcers, a fever or unexplained bruising needs urgent attention: in rare cases carbimazole causes a sharp fall in the white blood cells that fight infection. Yellowing of the eyes or skin, pale stools and dark urine point to the liver and also need attention quickly.
Carbimazole with other medicines
Carbimazole can change how warfarin and other blood thinners behave. It also alters theophylline levels, and theophylline is used for asthma. Medicines that lower blood counts in their own right add to the same small risk. Iodine supplements, kelp among them, work against the tablets, so they are usually left out while thyroid levels are being corrected.
