Darzalex Complications and Management Strategies for Adverse Reactions
Darzalex, a brand-name IV infusion, is commonly used to treat multiple myeloma. While the medication is generally well-tolerated, it's essential to be aware of its potential side effects.
One of the reported side effects is diarrhea, which can lead to dehydration if severe. To stay hydrated during treatment, it's recommended to drink plenty of fluids and consider drinks like Gatorade or Pedialyte.
Reactions to an infusion are another reported side effect. These can occur during or shortly after the infusion and may require pre-treatment with certain medications such as a steroid, antihistamine, and a fever medication. In rare cases, severe infusion reactions can cause symptoms including swelling under the skin, trouble breathing, changes in blood pressure, wheezing, nausea, and vomiting, eye pain, and, in extreme cases, anaphylaxis.
Anemia, causing fatigue, lightheadedness, shortness of breath, and skin that looks paler than usual, is another potential side effect. If you experience symptoms of anemia during treatment, it's crucial to inform your doctor, who may check your red blood cell level and wait until it returns to normal before giving your next Darzalex infusion.
Less common but serious side effects include severe infections, pulmonary edema, atrial fibrillation, and serious allergic symptoms like wheezing, hypotension, and chest discomfort. These symptoms may indicate hypersensitivity and should be reported to 911 or your local emergency number right away.
Upper respiratory infection is a common side effect, while mild infusion reactions can cause symptoms such as hives, skin rash, or fever. If you have mild symptoms, they may slow or stop the infusion, and your next infusion may be given over a longer period of time.
Other potential serious side effects include pneumonia, peripheral sensory neuropathy, peripheral edema, low levels of platelets, shingles, low levels of certain white blood cells, severe diarrhea, and anemia.
The Food and Drug Administration (FDA) tracks side effects of medications, including Darzalex. To report a side effect, visit MedWatch. For more information about the side effects of Darzalex, refer to its prescribing information.
It's important to note that Darzalex is often used in combination with other cancer drugs. Additionally, Darzalex and Darzalex Faspro are both approved to treat multiple myeloma, with Darzalex Faspro also approved to treat light-chain amyloidosis.
Close monitoring is essential to promptly manage these less common but serious side effects. For more detailed information, consult the European Medicines Agency’s Darzalex summary or the Mayo Clinic's Daratumumab side effects guide.
- Science continues to study the various medical-conditions linked to Darzalex usage, such as cancer, anemia, upper respiratory infection, pneumonia, peripheral sensory neuropathy, peripheral edema, low levels of platelets, shingles, and low levels of certain white blood cells.
- Serious side effects like severe infections, pulmonary edema, atrial fibrillation, and serious allergic symptoms require immediate medical attention and may necessitate the use of medications such as a steroid, antihistamine, and a fever medication pre-treatment.
- Besides diarrhea and dehydration, potential side effects with optimum hydration management include anemia, causing fatigue, lightheadedness, shortness of breath, and paler-looking skin; mild infusion reactions, manifesting in symptoms like hives, skin rash, or fever; and severe infusion reactions with symptoms especially requiring prompt emergency care, such as swelling under the skin, trouble breathing, changes in blood pressure, wheezing, nausea, vomiting, eye pain, and anaphylaxis.
