What should I discuss with my healthcare provider before taking lansoprazole (Prevacid)?
Heartburn is often confused with the first symptoms of a heart attack. Seek emergency medical attention if you have chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, and a general ill feeling.
You should not use this medication if you are allergic to lansoprazole.
Ask a doctor or pharmacist if it is safe for you to take lansoprazole if you have liver disease, or low levels of magnesium in your blood.
Do not use over-the-counter lansoprazole (Prevacid 24HR) 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 conditions are treated with a combination of lansoprazole and antibiotics. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.
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. Before you take this medication, tell your doctor if you have osteoporosis or osteopenia (low bone mineral density).
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether lansoprazole passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Some forms of lansoprazole may contain phenylalanine. Tell your doctor if you have phenylketonuria.
Do not give this medication to a child younger than 1 year old.
How should I take lansoprazole (Prevacid)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Lansoprazole is usually taken before eating. Follow your doctor's instructions.
Do not crush or break a delayed-release capsule. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.
If you are unable to swallow a delayed-release capsule whole: Open the capsule and sprinkle the medicine into a spoonful of pudding, applesauce, yogurt, cottage cheese, strained pears, or a nutritional drink such as Ensure. Swallow this mixture right away without chewing. Do not save the mixture for later use. Discard the empty capsule.
You may also dissolve the medicine from a lansoprazole capsule in 2 ounces (1/4 cup) of apple juice, orange juice, or tomato juice. Stir this mixture and drink all of it right away. To make sure you get the entire dose, add a little more juice to the same glass, swirl gently and drink right away.
Dissolve the oral granules in 2 tablespoons of water. Use only water when mixing lansoprazole oral granules. Stir this mixture and drink all of it right away. To make sure you get the entire dose, add a little more water to the same glass, swirl gently and drink right away.
Shake the oral suspension (liquid) well just before you measure a dose. Measure the liquid with a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
To take lansoprazole orally disintegrating tablet: Use dry hands to remove the tablet and place it in your mouth. It will begin to dissolve right away. Allow the tablet to dissolve in your mouth without chewing, swallowing several times as it dissolves.
The orally disintegrating tablet should not be given with an oral syringe or given through a nasogastric (NG) feeding tube. The tablet may not dissolve completely and could clog the syringe or tube.
Prevacid 24HR should be taken only once every 24 hours for 14 days. Take the medicine in the morning before you eat breakfast. It may take up to 4 days for full effect. Do not take more than one tablet every 24 hours.
Allow at least 4 months to pass before you start another 14-day treatment with Prevacid 24HR. Call your doctor if you have additional symptoms and need treatment before the 4 months has passed.
Do not crush, chew, or break a Prevacid 24HR capsule. Swallow the pill whole.
Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared.
Call your doctor if your symptoms do not improve or if they get worse while you are taking this medicine.
Store at room temperature away from moisture and heat. Do not freeze the liquid medicine and protect it from light.
