Opdivo can cause muscle pain and weakness
Opdivo (nivolumab) is a brand-name IV infusion prescribed for some types of cancer in adults and certain children. It is an immunotherapy medication that helps the immune system recognize and attack cancer cells. It treats cancers of the lungs, kidneys, and other organs.
Like all drugs, Opdivo may cause side effects in some people. One of the common side effects of Opdivo is muscle pain and weakness. Muscle pain and weakness are not the only side effects of Opdivo. Other common side effects include fatigue, joint pain, skin rashes, nausea, infusion reactions, upset stomach, and injection site reactions.
Most pain-related side effects are mild and manageable with over-the-counter (OTC) pain relievers. However, in rare cases, muscle pain can turn into severe muscle inflammation. If you experience any side effects that bother you, get worse, or last long-term, be sure to talk to your doctor or pharmacist.
In rare cases, Opdivo can cause serious side effects. It can affect your thyroid gland, which is responsible for producing thyroid hormones. Opdivo can cause thyroid inflammation, low levels of thyroid hormones (hypothyroidism), and hypophysitis (inflammation of the pituitary gland). These side effects can sometimes become serious or life-threatening and can even lead to death.

Joint pain is a common side effect
Opdivo (nivolumab) is a brand-name IV infusion prescribed for some types of cancer in adults and certain children. It is a powerful and potentially life-saving treatment. However, as with other drugs, Opdivo can cause side effects, and joint pain is one of the most common.
Joint pain is a frequent occurrence for people undergoing treatment with Opdivo. This pain can manifest in various parts of the body, including the neck, back, and jaw. The good news is that most pain-related side effects are typically mild and manageable. Over-the-counter pain relievers, such as ibuprofen, can help alleviate the discomfort. Applying ice packs or warm compresses to the affected joints may also provide relief.
It is important to note that joint pain can sometimes be a sign of something more serious. In rare cases, Opdivo treatment has been associated with inflammatory arthritis. Therefore, it is crucial to monitor your symptoms and seek medical advice if the pain becomes more severe or persistent. Your healthcare provider will be able to assess your symptoms and recommend appropriate management strategies or further treatments.
Additionally, Opdivo may cause an allergic reaction in some individuals. Mild allergic reactions may present as a rash, while severe reactions can include swelling or difficulty breathing, which requires immediate medical attention. It is always advisable to consult your healthcare professional if you experience any new or worsening symptoms during Opdivo treatment.
While Opdivo can cause joint pain as a common side effect, it is important to remember that not everyone will experience this symptom. Individual variations exist, and side effects may depend on other factors, such as the use of additional medications or the type of cancer being treated. Nonetheless, being informed about potential side effects like joint pain can help patients proactively manage their symptoms and maintain open communication with their healthcare team.

Opdivo may cause an allergic reaction
Opdivo is a brand-name IV infusion prescribed for some types of cancer in adults and certain children. It is a medication that harnesses the immune system to help fight cancer. However, Opdivo may cause an allergic reaction in some individuals.
Opdivo may cause mild or severe allergic reactions. For mild allergic reactions, such as a mild rash, it is important to call your doctor right away. They may recommend treatments to help manage your symptoms and advise on whether to continue treatment.

Rare but serious side effects include immune-related inflammation
Opdivo (nivolumab) is a brand-name IV infusion prescribed for some types of cancer in adults and certain children. It works by harnessing the immune system to fight cancer. However, this mechanism can sometimes lead to rare but serious side effects, including immune-related inflammation.
One of the most concerning side effects of Opdivo is immune-related inflammation, which can affect various organs and tissues in the body. In rare cases, Opdivo can cause the immune system to attack healthy parts of the body mistakenly, leading to inflammation and damage to organs such as the liver and kidneys. This can result in serious and potentially life-threatening complications. Patients who have received a bone marrow (stem cell) transplant with donor stem cells are at an increased risk of developing graft-versus-host disease (GVHD), a severe complication that can be fatal.
Additionally, Opdivo can affect the thyroid gland, causing thyroid inflammation (thyroiditis) and hypothyroidism (low thyroid hormone levels). This side effect is more common when Opdivo is combined with other medications such as Yervoy (ipilimumab) or Cabometyx (cabozantinib). Symptoms of thyroid dysfunction can include fatigue, weight gain or loss, and changes in heart rate.
Another rare but serious side effect of Opdivo is immune-related inflammation in the joints, which can lead to arthritis. Joint pain is a common side effect of the drug, but in rare cases, it can progress to inflammatory arthritis. Patients experiencing joint pain during or after Opdivo treatment should consult their doctor, as they may recommend treatments to manage the symptoms and prevent further complications.
Furthermore, Opdivo may cause severe allergic reactions in some individuals. Mild allergic reactions may present as a rash, while severe reactions can include symptoms such as swelling or difficulty breathing, requiring immediate medical attention. It is important to note that the side effects of Opdivo can vary among individuals, and some people may be at higher risk for certain serious side effects, especially when Opdivo is combined with other medications.

Opdivo can affect the thyroid gland
Opdivo is an immunotherapy medication used to treat certain types of cancer. It works by harnessing the patient's immune system to fight cancer. However, this mechanism can sometimes cause the immune system to mistakenly attack healthy parts of the body.
One such organ that Opdivo can affect is the thyroid gland, which is responsible for producing thyroid hormones. These hormones help control how quickly the body breaks down food and turns it into energy, among other functions. Opdivo can cause thyroid inflammation, clinically known as thyroiditis, and low levels of thyroid hormone (hypothyroidism). Hypothyroidism is more likely when Opdivo is combined with Yervoy (ipilimumab) or Cabometyx (cabozantinib). Symptoms of hypothyroidism include increased weight, fatigue (low energy), feeling cold, a slow heart rate, depression, and a puffy face.
In rare cases, Opdivo can also cause high levels of thyroid hormone (hyperthyroidism). Symptoms of hyperthyroidism include a fast heart rate, high blood pressure, shaking hands, and difficulty sleeping.
If you experience any of the above symptoms, it is important to contact your doctor. They may pause or stop your Opdivo treatment, depending on the severity of the side effect. Your doctor may also recommend that you take other medications to treat thyroid dysfunction.
