If you have been prescribed Adco-Roznal, you may be using it because your doctor wants to reduce the amount of acid in your stomach. This can help when stomach acid is irritating or damaging areas such as your stomach lining, the first part of your small intestine, or your oesophagus, which is the tube that carries food from your mouth to your stomach.
Adco-Roznal contains lansoprazole 30 mg. Lansoprazole belongs to a group of medicines called proton pump inhibitors, often called PPIs. These medicines lower stomach acid.
What it is and what it is used for
Adco-Roznal is a capsule medicine. Each capsule contains:
- Lansoprazole 30 mg
Lansoprazole is the active ingredient. It reduces the amount of acid produced in your stomach.
Your doctor may prescribe Adco-Roznal if you have one of the following conditions:
- Duodenal ulcer
This is an ulcer in the first part of the small intestine. - Stomach ulcer
This is an ulcer in the lining of your stomach. - Reflux oesophagitis
This is inflammation of the oesophagus caused by stomach acid moving upwards from the stomach. - Helicobacter pylori infection
This is a bacterial infection in the stomach. When Adco-Roznal is used for this condition, it is used together with antibiotics.
Note: Adco-Roznal is a Schedule 4 medicine. This means you need a prescription to use it in South Africa.
How it works
Your stomach makes acid to help break down food. This acid is useful, but too much acid, or acid moving into the wrong place, can cause problems.
If you have an ulcer, acid can keep irritating the sore area. If you have reflux oesophagitis, acid can move up into your oesophagus and cause inflammation.
Adco-Roznal works by reducing acid production in the stomach. With less acid, the irritated area has a better chance to heal, and your symptoms may improve.
If you are being treated for Helicobacter pylori, Adco-Roznal helps by reducing stomach acid while the antibiotics work against the bacteria. It is important to take the full treatment exactly as your doctor prescribed it.
Who should NOT use this medicine
Do not use Adco-Roznal if you:
- Are allergic to lansoprazole.
- Are allergic to any of the other ingredients in the capsule.
- Are pregnant.
- Are breastfeeding.
- Have liver problems.
Warning: If any of these apply to you, do not take Adco-Roznal unless your doctor has specifically assessed your situation and advised you. If you are already taking it and realise one of these applies to you, contact your doctor or pharmacist.
