Nizatidine CAS number 76963-41-2
USES: Nizatidine is used to treat ulcers of the stomach and intestines
and prevent them from coming back after they have healed. This medication is
also used to treat certain stomach and throat (esophagus) problems caused by
too much stomach acid (e.g., erosive esophagitis) or a backward flow of
stomach acid into the esophagus (acid reflux disease/GERD). Decreasing extra
stomach acid can help relieve symptoms such as stomach pain, heartburn,
difficulty swallowing, persistent cough, and trouble sleeping. It can also
prevent serious acid damage to your digestive system (e.g., ulcers, cancer
of the esophagus).
Nizatidine belongs to a class of drugs commonly called H2 blockers. It works
by reducing the amount of acid in your stomach.
HOW TO USE: Take this medication by mouth with or without food,
usually once or twice a day as directed by your doctor. If you are taking
this medication once daily, it is usually taken right before bedtime. If you
are taking the solution, measure the dose carefully using a medication
spoon/cup. Do not use a household spoon.
The dosage and length of treatment are based on your medical condition and
response to therapy. Follow your doctor's instructions carefully. If you are
also taking antacids to relieve stomach pain as recommended by your doctor,
you may take them at the same time as nizatidine.
Take this medication regularly as prescribed in order to get the most
benefit from it. To help you remember, take it at the same time(s) each day.
Do not increase your dose or take it more often than directed. Continue to
take this medication for the prescribed length of treatment even if you are
feeling better. Stopping treatment too early may delay the healing process.
SIDE EFFECTS: Headache, dizziness, or diarrhea may occur. If any of
these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she
has judged that the benefit to you is greater than the risk of side effects.
Many people using this medication do not have serious side effects.
A very serious allergic reaction to this drug is unlikely, but seek
immediate medical attention if it occurs. Symptoms of a serious allergic

breathing.
This is not a complete list of possible side effects. If you notice other
effects not listed above, contact your doctor or pharmacist.
PRECAUTIONS: Before taking nizatidine, tell your doctor or pharmacist

Before using this medication, tell your doctor or pharmacist your medical
history, especially of: immune system problems, kidney problems, liver
