If you’ve had a serious allergic reaction to Tarpeyo, your doctor may recommend a different medication instead.

Tarpeyo for IgA nephropathy

Tarpeyo is approved to help reduce the loss of kidney function in adults with primary IgA nephropathy who are at risk for disease progression.

Primary IgA nephropathy is a type of kidney disease. (“Primary” means the condition is not caused by another health problem.) Symptoms may include blood in your urine, kidney pain, and swelling in your hands or feet.

With IgA nephropathy, an antibody (protein) called IgA builds up in your kidneys. This causes kidney damage and inflammation, which prevents your kidneys from removing waste substances from your body.

To learn more about Tarpeyo and IgA nephropathy, talk with your doctor.

The following drugs are similar to Tarpeyo:

If you can become pregnant, consider the following information about pregnancy and breastfeeding.

Tarpeyo and pregnancy

Taking oral budesonide, like Tarpeyo, may be safe during pregnancy. But animal studies using an injection form of budesonide showed risks of fetal harm, such as fetal loss and skeletal abnormalities. There are also risks involved in having untreated IgA nephropathy while pregnant. (Tarpeyo is used for treating IgA nephropathy.)

If you’re planning a pregnancy or can become pregnant, talk with your doctor about potential treatments for IgA nephropathy during pregnancy. Together, you can consider the risks and benefits of your treatment options and decide whether you should take Tarpeyo during pregnancy.

Tarpeyo and breastfeeding

It’s not known whether Tarpeyo should be taken while breastfeeding. But routine monitoring of infant growth is recommended with chronic use of budesonide.

If you’re currently breastfeeding or planning to do so, talk with your doctor before taking this medication.

Tarpeyo contains the active ingredient budesonide and is part of the drug class called corticosteroids.

Tarpeyo’s mechanism of action (how it works) is to reduce the amount of a certain antibody, IgA1, in your gut. With IgA nephropathy, which Tarpeyo is used to treat, too much IgA1 builds up in your kidneys, leading to inflammation and damage. By reducing the level of this antibody, Tarpeyo can help reduce the damage to your kidneys and the loss of kidney function.

Note: It’s not known whether the effectiveness of Tarpeyo is more due to the drug’s effects on the gut or to systemic (whole-body) effects.

Before taking Tarpeyo, discuss your health history with your doctor. Tarpeyo may not be right for you if you have certain medical conditions or other factors affecting your health. Be sure to talk with your doctor if any of the following apply to you:
