Risk of serious infections

Serious infections weren’t common in clinical trials of Lupkynis. There were reports of cytomegalovirus (CMV) infections and shingles. CMV infections are typically mild, but they can become serious in people with a weakened immune system.

Lupkynis works by weakening your immune system. This can make it more difficult for your body to guard against infections. While taking Lupkynis, you may have an increased risk of serious infections. These can be life threatening in rare cases.

Symptoms of an infection can include:

What you can do

If you notice symptoms of an infection while taking Lupkynis, talk with your doctor right away. If you have an infection, your doctor can prescribe a suitable treatment for it.

Before starting Lupkynis, you can ask your doctor whether you need any vaccines, such as the shingles vaccine.

You can also take steps to help lower your risk of getting an infection, such as:

  • washing your hands frequently using soap and water
  • avoiding touching your face, especially your eyes, nose, and mouth
  • trying to avoid being around people who have a cold or another infection

Risk of cancer

Lupkynis also has a boxed warning about the risk of cancer. Drugs that weaken the immune system, such as Lupkynis, can increase the risk of some cancers, including skin cancer and lymphoma. This side effect was very rare in clinical trials of Lupkynis.

Symptoms can vary depending on the type of cancer but may include:

The risk increases with higher doses of the drug or long treatment times.

What you can do

Contact your doctor if you notice symptoms of cancer during treatment with Lupkynis. Your doctor can examine your symptoms and determine the cause.

To lower your risk of skin cancer, try to avoid or limit your exposure to the sun. If possible, wear long-sleeve clothing and always use sunscreen with an SPF of 30 or higher. You should also avoid artificial UV light, such as tanning beds and sun lamps.

Lupkynis may cause several side effects. Here are some frequently asked questions about the drug’s side effects and their answers.

Can Lupkynis cause weight loss?

It’s unlikely that Lupkynis causes weight loss. In clinical trials, some people reported a decrease in appetite while taking the medication, but weight loss itself was not a common side effect.

If you notice significant weight loss while taking Lupkynis, talk with your doctor to make sure there isn’t another cause and discuss any necessary adjustments to your treatment.

Does Lupkynis cause long-term side effects?

It’s possible for Lupkynis to cause long-term side effects, but this isn’t common. Long-term side effects can start at any time during treatment. Or they may not go away, even after you’ve stopped taking the drug.

Possible long-term side effects of Lupkynis include certain cancers, which could require treatment long term. Lupkynis treatment can also increase the risk of serious infections. Such infections may have effects or symptoms that last even after the infection is gone.

Note that Lupkynis has boxed warnings for the risks of serious infections and cancer. For details, see the “Boxed warnings for Lupkynis” section.

Other precautions

Be sure to talk with your doctor about your health history before you take Lupkynis. This drug may not be the right treatment option for you if you have certain medical conditions or other factors that affect your health. These include:

Liver problems: If you have mild or moderate liver disease, your doctor will likely prescribe a lower dose of Lupkynis. If your condition is considered severe, such as cirrhosis, your doctor typically will not prescribe Lupkynis. They may be able to recommend a different treatment option for your condition.

Kidney problems: If you have a kidney problem, tell your doctor before you start taking Lupkynis. You may have an increased risk of kidney damage, a possible side effect of the drug. If you have severe kidney disease, your doctor may prescribe a lower dose or recommend a different treatment option for you. (Note that Lupkynis is prescribed to treat kidney inflammation caused by lupus.)

High blood pressure: Lupkynis can cause an increase in blood pressure as a side effect. If you already have high blood pressure, taking Lupkynis could worsen it. Tell your doctor if you have high blood pressure. They’ll monitor your blood pressure during treatment with Lupkynis. If your blood pressure gets too high, your doctor may change your blood pressure medications.

Heart problems: If you have a heart problem, such as heart failure, tell your doctor before starting Lupkynis. You may have a higher risk of heart rhythm problems as a side effect of the drug. Your doctor can help determine whether Lupkynis is a safe treatment option for you. Some other medications can also raise your risk of heart rhythm problems. For this reason, be sure to tell your doctor about all the medications that you take before starting Lupkynis.

Allergic reaction: If you’ve had an allergic reaction to Lupkynis or any of its ingredients, your doctor will likely not prescribe Lupkynis. Ask your doctor what other medications may be better options for you.

Pregnancy or breastfeeding: Lupkynis is not considered safe to take if you’re pregnant or breastfeeding. Be sure to tell your doctor that you’re pregnant or breastfeeding. They can let you know about other treatment options for your condition.

Alcohol consumption: There’s no known interaction between Lupkynis and alcohol. However, Lupkynis is typically taken with other drugs that may interact with alcohol. Talk with your doctor about whether consuming alcohol while taking Lupkynis is safe.
