Risks and warnings for Voquezna (vonoprazan)
Voquezna (vonoprazan) 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.
Possible risk of cancer
In some rare cases, heartburn can be warning signs of a more serious stomach problem or cancer. Sometimes, taking heartburn medications, like Voquezna (vonoprazan), can mask these warning signs. If your heartburn symptoms don't go away after you've completed treatment with Voquezna (vonoprazan), contact your provider. You might need to undergo testing to see if you have a more serious problem like stomach cancer.
Kidney problems
Some people reported inflammation in the kidneys after starting Voquezna (vonoprazan). Let your provider know if you notice changes to how much or how often you urinate, if you have blood in your urine, or are feeling unwell.
Infectious diarrhea
Risk factor: Taking Voquezna (vonoprazan) for a long time | Recent or current hospital stays | Taking antibiotics at the same time
Voquezna (vonoprazan) might raise your risk of infectious diarrhea from a bacteria called Clostridioides difficile (C. diff), which can be serious. It's important to recognize the difference between diarrhea as a side effect of Voquezna (vonoprazan) and this type of infectious diarrhea. Let your provider know if you experience diarrhea that doesn't get better over time, or is accompanied by fever, stomach cramps, and tiredness.
Weakened bones
- Risk factors: Taking Voquezna (vonoprazan) for a long time
Voquezna (vonoprazan) might weaken your bones and raise your risk of getting bone fractures. Your risk might be higher if you take Voquezna (vonoprazan) for a long time. Use Voquezna (vonoprazan) at the lowest dose and for the shortest amount of time possible for your condition.
Severe skin reactions
Some people have reported severe skin reactions, such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), after starting Voquezna (vonoprazan). These reactions can be life-threatening, but occur very rarely with Voquezna (vonoprazan). If you experience flu-like symptoms or a painful rash, get medical help as soon as possible.
Low magnesium and vitamin B12 levels
- Risk factors: Taking Voquezna (vonoprazan) for a long time | Taking other medications that lower vitamin B12 or magnesium
Taking Voquezna (vonoprazan) for a long time can cause low vitamin B12 levels. Your risk is higher if you're taking other medications that can do the same, such as metformin (Glucophage). Let your provider know if you feel symptoms of low vitamin B12 include low energy, headaches, and tiredness.
Voquezna (vonoprazan) can also lower magnesium levels, especially if you're taking other medication that can do the same, such as water pills or digoxin (Lanoxin). Talk to your provider if you notice any signs or symptoms of low magnesium (e.g., weakness or fatigue, muscle cramps, numbness).
Risk of false positive in lab test
Let your provider know you're taking Voquezna (vonoprazan) before you receive lab tests for neuroendocrine tumors. This medication can cause a rise in serum chromogranin A (CgA) level, which suggests you have a certain type of tumor when you don't. If you need to take a test for CgA level, you must wait at least 2 weeks after you're finished with Voquezna (vonoprazan) treatment.
