Dexona - Dexamethasone 0.5mg Tablets, Pack of 90 Tablets

Dexamethasone treats problems driven by inflammation or an overactive immune system: severe allergic reactions such as anaphylaxis, severe skin conditions, inflammatory and autoimmune diseases, asthma flare-ups and croup in children. It is also used for certain blood, eye, thyroid and intestinal disorders, for sickness and vomiting, and to ease some side effects of cancer treatment. It is not a treatment for ordinary colds.

More than 1 in 100 people get weight gain, indigestion, trouble sleeping or mild mood changes. Serious effects are more likely at 6 mg a day or more, or beyond a month of treatment: infections, adrenal problems, high blood sugar, low potassium, a puffy rounded face with upper-body weight gain, eye problems and thinning bones. Get urgent help for breathlessness, swelling, black poo or vomiting blood.

Adults usually take 0.5 mg to 10 mg a day, and up to 16 mg a day for some conditions. It is normally taken once daily in the morning with or straight after breakfast, not on an empty stomach, so it is less likely to keep you awake. Follow your prescription exactly.

After more than a few weeks your doctor will taper the dose over several weeks so the adrenal glands can recover.

Yes, alcohol is allowed with dexamethasone and it does not cancel the medicine's effect. Even so, drinking can add to stomach irritation and sleep problems, which are already common side effects. If you have a history of stomach ulcers, or take high-dose aspirin or anti-inflammatory painkillers, guidance is to limit alcohol, because the combination raises ulcer risk.

Yes. Rifampicin, rifabutin, carbamazepine, phenytoin and phenobarbitone can weaken its effect, while antifungal medicines, macrolide antibiotics and HIV medicines can raise its levels and side effects. It can strengthen warfarin, add to potassium loss with diuretics, and increase ulcer risk with anti-inflammatory painkillers. Live vaccines must be avoided.
