Adalimumab : Drug Facts, Indications, Side Effects and Dosing

Rheumatoid Arthritis is a chronic inflammatory disorder of the joints that may cause painful swelling and result into joint deformity or bone erosion. It is one of the most common auto-immune disorders today and occurs when the immune system attacks its own body’s tissues mistakenly. Rheumatoid Arthritis is more common in women in the age group of 30 to 50 years. Adalimumab may help alleviate the symptoms of Rheumatoid Arthritis and other inflammatory diseases.

What is Adalimumab?

Adalimumab, trade name Exemptia, is a potent TNF-inhibitor and anti-inflammatory drug manufactured and promoted by Zydus Group in India. When people have Rheumatoid Arthritis or other inflammatory diseases, it causes over-secretion of TNF, a protein naturally produced in the body, causing inflammation and damage to the joints. Adalimumab works as anti-TNF, blocking over production of TNF and its harmful effects on the body. It helps to reduce inflammation and alleviate the symptoms of arthritis and other joint disorders.

When is Adalimumab Prescribed?

Adalimumab is prescribed to people who have Rheumatoid Arthritis, Ankylosing Spondylitis, Psoriatic Arthritis, and to children having Juvenile Idiopathic Arthritis (JIA).

The guidelines for when is Adalimumab prescribed varies from region to region and based on the kind of disorder. If a person has Rheumatoid Arthritis, Exemptia will only be prescribed by the doctors if:

• the condition is active, and
• if the patient has already used Methotrexate or other Disease-Modifying Anti Rheumatic Drug (DMARD) like Hydroxychloroquine or Sulfasalazine, or
• the person cannot use these medicines from some reason

What are the Possible Side Effects of Adalimumab?

Here, it is important to know how Adalimumab works. The TNF-inhibitor affects the body’s defense system, i.e. the immune system. Therefore, you may develop certain infections. On the other hand, it may only show the symptoms of an infection, while you might not actually be affected. However, you should inform your doctor if you develop fever, sore throat, any symptoms of infection or any new symptoms that concern you.

When to See a Doctor?

Typically, usage of Adalimumab does not cause any serious side effects. However, you should stop taking the drug and consult your doctor immediately if you experience:

• Severe allergic reactions like difficulty breathing, rashes, itching, swelling of the mouth, unusual hoarseness or tightness in the chest
• Blood in urine or stool
• Open sore that does not heal
• Chest pain; irregular or fast heartbeat
• Mood swings and depression
• Butterfly-shaped rashes on the cheeks and nose
• Persistent pain, redness or swelling at the injection site
• Flu-like symptoms
• Blood in the phlegm
• Persistent or severe headache, nausea and dizziness
• Unusual bleeding or bruising
• Vision changes
• Unusual weakness and tiredness

These are only few possible side effects that may occur when you use Adalimumab. If you see or feel something unusual or persistent, contact your doctor immediately.

If you develop Chickenpox or Shingles while you are on Adalimumab, consult your doctor immediately. You may be put under anti-viral treatment and your dosage of Adalimumab will be stopped.

The long-term side effects of Adalimumab are still unknown since it is relatively a new drug.

What are the Risks of Taking Adalimumab?

Since Adalimumab affects the immune system, you might be at a risk of certain infections and other health conditions.

There might be a little increased risk of developing cancers in patients using the drug that affects the body’s immune system. However, this hasn’t been proven yet and is under research. Often, TNF-inhibitor drugs have been associated with certain kinds of skin cancer, which can be treated if diagnosed early.

In very rare cases, Adalimumab may cause a condition called Drug-induced Lupus. The symptoms include fever, rash, increased joint pain. The health condition is mild and can be easily diagnosed by a blood test.

How to Reduce the Risk of Infection?

Since the drug affects your immune system, with Adalimumab you may be at a higher risk of developing infections. When you are using the medicine, avoid close contact with people having severe and active infections. Thoroughly clean your hands before taking food as this may help prevent spreading of germs.

Is There Any Interaction Between Adalimumab and Alcohol?

Though no known interactions have been found between Adalimumab and alcohol, it is recommended that you keep well within limits if you are also taking Methotrexate. The latter and alcohol can interact and cause liver damages. The recommended amount of alcohol is 2-3 units per day for women and 3-4 units per day for men. In certain cases, the doctor may recommend even lower limits like 4 units per week if you are suffering from Psoriatic Arthritis.

Will Taking Adalimumab Affect Vaccinations?

If you are on Adalimumab, it is advised to avoid live vaccinations like Yellow Fever. In certain cases where live vaccine may be necessary as for Rubella immunization in female of childbearing age, your doctor may discuss the possible benefits or risks of the vaccination and its interaction with the drug.

Pneumovax and annual flu vaccines have been proved to have no interaction with Adalimumab and are recommended.

If you are aged 70 or more and prescribed Shingles vaccination, your doctor may recommend you to have it before you start the drug. Typically, Shingles vaccine is not advised for people who are on Adalimumab already.

Adalimumab and Pregnancy

Though there are no scientific findings regarding Adalimumab and pregnancy, it is often recommended that women of childbearing age use contraception while using the drug. If you are pregnant or planning to get pregnant, discuss with your doctor or gynecologist whether you should or not stop using the drug. Your doctor will weigh the benefits of using the drug to control your arthritis as against its possible risk on your pregnancy or fertility. It is important to remember here that uncontrolled arthritis may also affect the unborn baby. If your doctor recommends not using Adalimumab any further when you are trying to get pregnant, then you should continue using contraception for at least 5 months after stopping the medicine and give your body the time to completely flush it out of your system.

Does Adalimumab Affects Breastfeeding?

Usually, breastfeeding is not recommended if you are on Adalimumab, or you should not use the drug if you are breastfeeding. The medicine may pass into your breast milk and could be harmful to the baby.
