Klinisk författares anmärkning Michael Stewart 24/5/2021: Alu-Cap® capsules were discontinued in the UK in May 2019. At the time of review there are no branded or generic products solely containing aluminium hydroxide in the UK. Aluminium hydroxide may be available as a special order and is included as an ingredient in some antacid remedies. It may also still be available in other countries. This medicine leaflet is based on medical information accessed in the UK at the time of writing and is left here for reference purposes. Please also refer to the manufacturer's information supplied with your medicine.
Aluminium hydroxide is taken for indigestion. It is also taken to control high phosphate levels in people with kidney disease.
Do not take the capsules at the same time as other medicines - leave two hours between taking aluminium hydroxide capsules and any other medicines.
The most common side-effect is constipation.

About aluminium hydroxide
Typ av medicin | An antacid |
Används för | As an antacid for indigestion; to control high phosphate levels in people with kidney disease |
Även kallad | Alu-Cap® (discontinued) |
Tillgänglig som | capsules |
Aluminium hydroxide is an antacid, which means that it neutralises excess stomach acid associated with matsmältningsbesvär. It also helps to protect the lining of your stomach from acid irritation.
Aluminium hydroxide can also reduce the amount of phosphate which your body absorbs from the food you eat. It combines with phosphate in your stomach, and this is then removed instead of being absorbed. Although aluminium hydroxide is sometimes prescribed for this purpose in people with certain kidney diseases, other medicines are usually used in preference to it.
Before taking aluminium hydroxide
To make sure this is the right treatment for you, before you take aluminium hydroxide capsules it is important that your doctor or pharmacist knows:
Om du är gravid eller ammar.
If you have any problems with the way your liver works or any problems with the way your kidneys work.
If you have been told you have low levels of phosphate in your blood.
Om du någonsin har haft en allergisk reaktion mot en medicin.
Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.
How to take aluminium hydroxide
Before you start taking aluminium hydroxide, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about aluminium hydroxide and will provide you with a full list of the side-effects which you may experience from taking it.
For indigestion in adults, take one capsule four times a day with meals and one at bedtime. The capsules are not suitable for children to take as an antacid. Antacids are best taken when symptoms are likely to occur.
If you are taking aluminium hydroxide to reduce the amount of phosphate in your body, your doctor will tell you how many capsules to take each day. You could be asked to take between 4-20 capsules a day. Take the capsules spaced out throughout the day with your meals.
Aluminium hydroxide can interfere with other medicines taken at the same time and can prevent them from being absorbed properly. It is best if you leave two hours between taking aluminium hydroxide and any other medicines.
