What is lansoprazole?
Lansoprazole is a proton pump inhibitor. Lansoprazole decreases the
amount of acid produced in the stomach.
Lansoprazole is used to treat and prevent stomach and intestinal
ulcers, erosive esophagitis (damage to the esophagus from
stomach acid), and other conditions involving excessive stomach acid
such as Zollinger-Ellison syndrome.
Over-the-counter lansoprazole (Prevacid OTC) is used to treat
frequent heartburn that happens 2 or more days per week.
Lansoprazole is not for immediate relief of heartburn symptoms.
Lansoprazole may also be used for purposes not listed in this
medication guide.
What are the possible side effects of lansoprazole?
Get emergency medical help if you have signs of an allergic reaction:
hives; difficulty breathing; swelling of your face, lips, tongue, or
throat.
Call your doctor at once if you have:
* severe stomach pain, diarrhea that is watery or bloody;
* new or unusual pain in your wrist, back, hip, or thigh;
* a seizure (convulsions);
* irregular heartbeats;
* kidney problems--little or no urination, blood in your urine,
swelling, rapid weight gain; or
* new or worsening symptoms of lupus--joint pain, and a skin rash
on your cheeks or arms that worsens in sunlight.
Common side effects may include:
* nausea, stomach pain;
* diarrhea, constipation; or
* headache.
This is not a complete list of side effects and others may occur. Call
your doctor for medical advice about side effects. You may report side
effects to FDA at 1-800-FDA-1088.

What should I discuss with my healthcare provider before taking lansoprazole?
Heartburn can mimic early symptoms of a heart attack. Get emergency
medical help if you have chest pain that spreads to your jaw or
shoulder and you feel anxious or light-headed.
You should not use this medicine if you are allergic to lansoprazole,
or if you take any medicine that contains rilpivirine (Edurant,
Complera, Odefsey).
Tell your doctor if you have ever had:
* liver disease;
* lupus;
* low levels of magnesium in your blood; or
* osteoporosis or low bone mineral density (osteopenia).
Do not use over-the-counter lansoprazole (Prevacid OTC) without the
advice of a doctor if you have:
* trouble or pain with swallowing;
* bloody or black stools; vomit that looks like blood or
coffee grounds;
* heartburn that has lasted for over 3 months;
* frequent chest pain, heartburn with wheezing;
* unexplained weight loss;
* nausea or vomiting, stomach pain; or
* an electrolyte imbalance or metabolic disorder.
Some forms of lansoprazole may contain phenylalanine. Tell your
doctor if you have phenylketonuria (PKU).
Taking a proton pump inhibitor such as lansoprazole may increase your
risk of bone fracture in the hip, wrist, or spine. This effect has
occurred mostly in people who have taken the medication long term or at
high doses, and in those who are age 50 and older. It is not clear
whether lansoprazole is the actual cause of an increased risk of
fracture.
Some conditions are treated with a combination of lansoprazole and
antibiotics. Use all medications as directed by your doctor
Do not give lansoprazole to a child younger than 1 year old. Prevacid
OTC is not approved for use by anyone younger than 18 years old.
Ask a doctor before using this medicine if you are pregnant or
breast-feeding.
How should I take lansoprazole?
Follow all directions on your prescription label and read all
medication guides or instruction sheets. Use the medicine exactly as
directed.
Lansoprazole is usually taken before eating. Prevacid OTC should be
taken in the morning before you eat breakfast.
Shake the oral suspension (liquid) before you measure a dose. Use the
dosing syringe provided, or use a medicine dose-measuring device (not a
kitchen spoon).
Swallow the capsule whole and do not crush, chew, break, or open it.
Remove an orally disintegrating tablet from the package only when you
are ready to take the medicine. Place the tablet in your mouth and
allow it to dissolve, without chewing. Swallow several times as the
tablet dissolves.
Read and carefully follow any Instructions for Use provided with your
medicine. Ask your doctor or pharmacist if you do not understand these
instructions.
Use this medicine for the full prescribed length of time, even if your
symptoms quickly improve.
Prevacid OTC should be taken only once daily for 14 days. It may take
up to 4 days for full effect. Allow at least 4 months to pass before
you start another 14-day treatment with Prevacid OTC.
Call your doctor if your symptoms do not improve or if they get worse
while you are taking lansoprazole. If you take Prevacid OTC, call your
doctor if your heartburn gets worse over the 14-day treatment, or if
you need treatment more than once every 4 months.
If you use lansoprazole for longer than 3 years, you could develop a
vitamin B-12 deficiency. Talk to your doctor about how to manage this
condition if you develop it.
Store at room temperature away from moisture, heat, and light. Do not
freeze the liquid medicine.

What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if it is
almost time for your next dose. Do not take two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at
1-800-222-1222.
What should I avoid while taking lansoprazole?
This medicine can cause diarrhea, which may be a sign of a new
infection. If you have diarrhea that is watery or bloody, call your
doctor before using anti-diarrhea medicine.
What other drugs will affect lansoprazole?
Sucralfate (Carafate) can make it harder for your body to
absorb lansoprazole. Wait at least 30 minutes after taking
lansoprazole before you take sucralfate.
Sometimes it is not safe to use certain medications at the same time.
Some drugs can affect your blood levels of other drugs you take, which
may increase side effects or make the medications less effective.
Many drugs can affect lansoprazole, and some drugs should not be used
at the same time. This includes prescription and over-the-counter
medicines, vitamins, and herbal products. Not all possible interactions
are listed here. Tell your doctor about all your current medicines and
any medicine you start or stop using.
Where can I get more information?
Your pharmacist can provide more information about lansoprazole.
