What is Humira (Adalimumab)?

Humira (Adalimumab) is a medication used to treat various inflammatory conditions, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, and plaque psoriasis. It belongs to a class of drugs called TNF blockers, which work by blocking the action of a protein called tumor necrosis factor (TNF). TNF is a protein produced by the immune system that can cause inflammation and damage to the body's tissues.

Humira is approved by the FDA for use in adults and children over the age of 6. It is administered as an injection under the skin and can be self-administered by patients or given by a healthcare provider.

The active ingredient in Humira is adalimumab, which is a monoclonal antibody that specifically targets TNF. Adalimumab is produced by genetically engineered cells and is designed to bind to TNF and prevent it from causing inflammation.

Humira has been shown to be effective in reducing the signs and symptoms of inflammatory conditions and improving patients' quality of life. However, it can also cause side effects, including an increased risk of infections, allergic reactions, and other serious adverse events.

Patients who are prescribed Humira should be closely monitored by their healthcare provider and should report any side effects or changes in their condition. Humira should not be used by patients with active infections or a history of tuberculosis, and it may interact with other medications, so patients should inform their healthcare provider of all medications they are taking.

Warnings and Precautions

Humira (Adalimumab) is a powerful medication used to treat various inflammatory conditions. However, it is important to note that there are some warnings and precautions associated with the use of this medication.

One of the most important warnings is the increased risk of infections. Humira can lower the body's ability to fight infections, making it easier to get sick. Patients should be monitored for signs of infection and should report any symptoms to their healthcare provider immediately.

Another important precaution is the risk of tuberculosis (TB). Patients should be screened for TB before starting Humira. If a patient has a history of TB or has been in close contact with someone who has TB, they should not take Humira unless they have been treated for TB first.

Humira may also increase the risk of certain types of cancer, such as lymphoma. Patients should be monitored for signs of cancer, and any suspicious symptoms should be reported to their healthcare provider.

Patients with hepatitis B should also be cautious when taking Humira. The medication can cause the virus to become active again, which can lead to serious liver problems. Patients should be tested for hepatitis B before starting Humira.

Other precautions include heart failure, vaccine administration, multiple sclerosis, allergy, trouble breathing, dark urine, loss of appetite, nerve-muscle disorder, major surgery, unborn baby, breastfeeding, and corticosteroids. Patients should discuss these risks with their healthcare provider before starting Humira.

In summary, Humira is a powerful medication that can be very effective in treating inflammatory conditions. However, there are some important warnings and precautions associated with its use. Patients should be aware of these risks and should discuss them with their healthcare provider before starting Humira.

Interactions with Other Medicines

When taking Humira, it is important to be aware of its potential interactions with other medications. Patients should always inform their healthcare provider of all medications they are currently taking, including prescription and over-the-counter drugs, as well as any herbal supplements.

One medication that may interact with Humira is methotrexate, which is commonly used to treat rheumatoid arthritis. When taken together, the risk of infections may increase. Therefore, the healthcare provider may adjust the dosage of one or both medications to minimize the risk.

Another medication that may interact with Humira is biosimilar drugs. Biosimilars are similar to Humira and are used to treat the same conditions. Patients should consult their healthcare provider before taking biosimilars with Humira to ensure that the combination is safe and effective.

Infliximab is another medication that may interact with Humira. Both medications are used to treat inflammatory conditions, and when taken together, the risk of infections may increase. Therefore, the healthcare provider may adjust the dosage of one or both medications to minimize the risk.

Corticosteroids may also interact with Humira. When taken together, the risk of infections may increase. Patients should consult their healthcare provider before taking corticosteroids with Humira to ensure that the combination is safe and effective.

It is important to note that this list is not exhaustive, and patients should always consult their healthcare provider before taking any new medications with Humira.

Humira and Pregnancy

Humira (Adalimumab) is a medication that is used to treat various autoimmune conditions such as rheumatoid arthritis, psoriatic arthritis, Crohn's disease, and ulcerative colitis. However, it is important to note that there are potential risks associated with using Humira during pregnancy.

If a woman is pregnant or planning to become pregnant, it is important to discuss the risks and benefits of using Humira with her healthcare provider. The FDA has classified Humira as a pregnancy category B drug, which means that it has not been shown to cause harm to an unborn baby in animal studies. However, there are no adequate and well-controlled studies in pregnant women.

It is also important to note that Humira can pass into breast milk and may harm a nursing baby. Therefore, women who are breastfeeding should also discuss the risks and benefits of using Humira with their healthcare provider.

Overall, the use of Humira during pregnancy and breastfeeding should be carefully considered and discussed with a healthcare provider. It is important to weigh the potential benefits of the medication for the mother against the potential risks to the unborn baby or nursing infant.

Cost and Availability

Humira is a brand-name drug that can be quite expensive. The cost of Humira can vary depending on a number of factors, including the dosage, the frequency of use, and the location of the pharmacy. According to GoodRx, the average retail price of a 40mg/0.8mL Humira pen is around $5,400. However, the cost of the medication can be significantly lower if the patient has insurance or qualifies for financial assistance.

In addition to the brand-name Humira, there are also biosimilars available on the market. Biosimilars are drugs that are similar to the original biologic drug, but are not identical. One biosimilar to Humira is Amjevita, which was approved by the FDA in 2016. According to GoodRx, the average retail price of a 40mg/0.8mL Amjevita pen is around $4,000, which is slightly lower than the cost of Humira.

It's important to note that while biosimilars are often less expensive than the brand-name drug, they are not always interchangeable. Patients should talk to their healthcare provider to determine if a biosimilar is an appropriate treatment option for their condition.

Overall, the cost and availability of Humira and its biosimilars can vary depending on a number of factors. Patients should talk to their healthcare provider and their insurance provider to determine the most cost-effective treatment option for their individual needs.
