What is Nizatidine?
Nizatidine is a type of medicine called an H2 receptor antagonist. The active ingredient, nizatidine, acts on H2 receptors: cells in the stomach lining that produce stomach acid. Nizatidine reduces the production of stomach acid, which encourages the gastrointestinal mucous membranes (oesophagus, stomach, duodenum) to relax. This eases symptoms such as gastro-oesophageal reflux, stomach or abdominal pain, and other stomach discomfort.
What is it used for?
Nizatidine is a stomach acid inhibitor used to treat stomach or intestinal ulcers, reflux (acid produced in the stomach that flows back into the food pipe) and pyrosis (heartburn). It can also be taken preventive to avoid stomach problems, for example caused by the use of certain medicines.
How to use Nizatidine
Nizatidine capsules should be swallowed whole with some liquid, without chewing, preferably after meals. As it takes on average four to eight weeks for the gastrointestinal mucous membranes to heal, Nizatidine is usually taken for a long period of time.
If you have missed a dose, you may take it as soon as you remember, unless it is almost time for your next scheduled dose. Never take a double dose of Nizatidine to make up for the forgotten one.
Nizatidine is available in packs containing 30 capsules of 150 mg and 300 mg. The doctor will recommend the right dose for you. Unless otherwise prescribed by the doctor, the usual dose for adults is:
- 300 mg once daily or 150 mg twice daily.
The duration of the treatment is decided by the doctor. Nizatidine is not suitable for use in children.
Nizatidine may have side effects, although not everybody gets them. The most commonly reported side effects include:
- Headache, sleepiness, dizziness (usually only temporary).
- Flu or common cold symptoms such as coughing, muscle ache, runny nose/nasal congestion, fever (usually only temporary).
See package leaflet for more side effects, warnings and contraindications.
If you are pregnant, do not use Nizatidine without the doctor’s approval. Nizatidine is safe to use while breastfeeding.
Nizatidine can cause dizziness and sleepiness. Do not drive or operate machinery if you experience these side effects.
Alcohol is known to have an adverse effect on the stomach’s mucous membranes. You should therefore avoid alcohol if you are being treated for stomach problems.
