Precautions

It is important that your doctor check your or your child's progress at regular visits. This will allow your doctor to see if this medicine is working properly and to decide if you should continue to take it. Blood, urine, and other laboratory tests may be needed to check for unwanted effects.

Do not take this medicine if you are also using products that contain rilpivirine (Complera®, Edurant®). Using these medicines together may cause unwanted side effects.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Check with your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Check with your doctor right away if you or your child has a change in frequency of urination or amount of urine, blood in the urine, fever, joint pain, loss of appetite, skin rash, swelling of the body, feet, or ankles, unusual tiredness or weakness, or unusual weight gain after receiving this medicine. These could be symptoms of a serious kidney problem called acute tubulointerstitial nephritis.

Taking this medicine for a long time may make it harder for your body to absorb vitamin B12. Tell your doctor if you have concerns about vitamin B12 deficiency.

Serious stomach conditions may occur while taking this medicine. Check with your doctor immediately if you or your child has stomach cramps, bloated feeling, watery and severe diarrhea which may also be bloody sometimes, fever, nausea or vomiting, or unusual tiredness or weakness.

Dexlansoprazole may increase your risk of having fractures of the hip, wrist, and spine.

Call your doctor right away if you have severe bone pain or are unable to walk or sit normally.

This medicine may cause hypomagnesemia (low magnesium in the blood). This is more likely to occur if you are taking this medicine for more than 1 year, or if you are taking this medicine together with digoxin (Lanoxin®) or certain diuretics (water pills). Check with your doctor right away if you have convulsions (seizures), fast, racing, or uneven heartbeat, muscle spasms (tetany), tremors, or unusual tiredness or weakness.

This medicine may increase your risk for fundic gland polyps (abnormal tissue growth in the upper part of your stomach). This is more likely if you are receiving this medicine for more than 1 year. Talk to your doctor if you have concerns.
