Pharmacist tips for Lansoprazole (Prevacid)
- Typically, lansoprazole (Prevacid) is taken before your meals. If you're taking the medication twice daily, take your first dose before breakfast and your second dose before dinner. Ask your provider or pharmacist if you have questions about the best time to take lansoprazole (Prevacid).
- Swallow the lansoprazole (Prevacid) pills whole. Don't chew or crush the pills. Doing so can change how the medication gets absorbed into your body.
- Lansoprazole (Prevacid) capsules: If you can't swallow the capsules, you can open the capsule and sprinkle the granules inside onto one tablespoon of applesauce, cottage cheese, or yogurt. Alternatively, you can also mix the granules with 60 mL of apple or orange juice. Once mixed, swallow the mixture right away without chewing or crushing the granules. You can drink some water afterwards to make sure you've swallowed all the medication. Don't save any of the mixture for later, since the medication might not work as well anymore.
- Lansoprazole (Prevacid) orally disintegrating tablets: Make sure your hands are dry before handling lansoprazole (Prevacid) tablets. Place the tablet on your tongue to let it dissolve for about a minute. You can take it with water or swallow the medication with saliva.
- Lansoprazole (Prevacid) can interact with many medications. Let your provider or pharmacist know what medications you take or plan to take. These medications include over-the-counter products and supplements. Talk with your provider or pharmacist if you have any questions about interactions with this medication.
- If you're ready to stop lansoprazole (Prevacid), ask your provider if they need to lower your dose slowly over time. Stopping PPIs suddenly, especially after you've been taking one regularly for a while, might cause GERD symptoms to flare up.
Over-the-counter lansoprazole (Prevacid)

Risks and warnings for Lansoprazole (Prevacid)
Lansoprazole (Prevacid) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk of hiding symptoms of a more serious problem
Frequent episodes of heartburn can be a symptom of stomach cancer. If your heartburn gets worse or comes back after taking lansoprazole (Prevacid), let your provider know. Also contact your provider if you have poor appetite, unexplained weight loss, or weakness along with your heartburn. They can check if there are other serious medical problems going on.
Sudden kidney problems
Some people taking PPIs like lansoprazole (Prevacid) have had sudden kidney problems. These problems can happen at any point during treatment. Talk with your provider if you are urinating more or less than usual, feel nauseous or weak, or have a fever, rash, or joint pain. These can be symptoms of kidney problems.
Severe infectious diarrhea
- Risk factors: Older people | Recent stay at a hospital or nursing home | People with a weakened immune system (e.g., HIV, cancer)
Some clinical studies showed that PPIs, such as lansoprazole (Prevacid), can raise the risk of getting a bacterial infection called Clostridioides difficile (C. diff). This infection can cause severe diarrhea. Your risk is higher if you're over 65 years old, have recently stayed at a hospital or nursing home, or have a weakened immune system. To lower your risk of C. diff diarrhea, take the lowest possible dose of lansoprazole (Prevacid) for the shortest amount of time that works well for you. If you experience severe or watery diarrhea, fever, belly pain, loss of appetite, or nausea, let your provider know right away.
Bone fractures
- Risk factors: Taking high doses of lansoprazole (Prevacid) | Taking lansoprazole (Prevacid) for longer than a year | Risk for osteoporosis
PPIs like lansoprazole (Prevacid) might raise the risk of bone fractures in the hip, wrist, or spine. Your risk is higher if you take more than one dose of lansoprazole (Prevacid) per day or if you take it for more than a year. To prevent the risk of bone fracture, take the lowest possible dose of lansoprazole (Prevacid) for the shortest amount of time for your symptoms. If you've had bone fractures before or have osteoporosis (weak bones), talk to your provider about your risk before using this medication.
Skin reactions
PPIs, such as lansoprazole (Prevacid), have rarely caused serious skin reactions. These reactions include Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Symptoms can include fever, body aches, rash, peeling skin, painful blisters, and swelling of the face. If you notice any of these symptoms, get medical help immediately.
Lupus
Some people taking PPIs like lansoprazole (Prevacid) developed new or worsening lupus, a condition where your immune system attacks your own body. Lupus symptoms can occur any time during treatment with lansoprazole (Prevacid). Some typical symptoms include joint pain or rash, but they often improve within 1 to 3 months of stopping this medication. If you experience any lupus symptoms while taking lansoprazole (Prevacid), stop the medication and contact your provider.
Low vitamin B12 and magnesium levels
- Risk factor: Long-term use | Taking medications that can lower magnesium levels
Using acid-lowering medications like lansoprazole (Prevacid) for a long period of time can cause your vitamin B12 levels to drop. Lansoprazole (Prevacid) lowers the amount of acid in your stomach, which is needed for vitamin B12 absorption. If you've been taking this medication for longer than 3 years, or if you have symptoms of vitamin B12 deficiency (e.g., dizziness, muscle weakness, pale skin, tiredness, tingling in arms or legs), talk to your provider.
Taking lansoprazole (Prevacid) can also lower your magnesium levels. This can happen 3 months after taking lansoprazole (Prevacid), but it's more likely after a year of treatment. Low magnesium levels can sometimes lead to other electrolyte problems. You're at risk for low magnesium levels if you take other medications that can affect electrolyte levels, such as digoxin (Lanoxin) or water pills. Your provider might check your blood during treatment with lansoprazole (Prevacid) to make sure your electrolyte levels are in the normal range. Watch for symptoms of electrolyte problems like irregular heart rate, muscle cramps, and tremors. Let your provider know right away if they occur.
Interaction with other medications
Some medications can interfere with how your body gets rid of lansoprazole (Prevacid). Depending on if they boost or block how lansoprazole (Prevacid) gets removed, the medications can affect the amount of lansoprazole (Prevacid) in your body, how well it works, and the risk of side effects. For example, St. John’s Wort and rifampin (Rifadin) can lower the amount of lansoprazole (Prevacid) in your body and cause the medication to not work as well. Avoid these medications while taking lansoprazole (Prevacid).
Lansoprazole (Prevacid) can also interfere with how other medications work. lansoprazole (Prevacid) can raise the risk of methotrexate toxicity when taken together with methotrexate. Lansoprazole (Prevacid) can also raise the risk of bleeding when taken together with warfarin (Coumadin). Your provider'll monitor your blood work regularly to make sure these medications are safe for you to take.
Caution use in people with phenylketonuria (PKU) - orally disintegrating tablets only
The orally disintegrating tablets of lansoprazole (Prevacid) contain phenylalanine, a sweetener that's often added to medications. Phenylalanine is harmless to most people, but it can be dangerous to people with an inherited medical condition called phenylketonuria (PKU). Avoid using the orally disintegrating tablets if you or your child has a history of PKU. Consider using the capsule formulation, which doesn't contain phenylalanine. Talk to a provider if you're not sure which products contain phenylalanine and which products are safer options before using any formulation.
