Interferon Alfa 2B Injection for Dermatology
Interferon is a protein that occurs naturally in the body in small amounts. Your injection will be
a protein that is synthetically produced in a large dose.
It is given as a subcutaneous (under the skin) injection most often in the abdomen or thigh. As a
rule, injections are given 3 times a week. Interferon is given to stimulate the body’s own
immune system to fight cancer.
Common side effects
Flu-like symptoms: chills, fever, joint, and muscle pains. You may take Tylenol before the
injection to help reduce these symptoms.
Fatigue: feeling of tiredness, and having no energy
Decreased blood count (your doctor will be ordering lab tests)
Increased blood pressure
Less common side effects
Skin irritation at the injection site
Pins and needles feeling in finger and toes
Pregnancy should be avoided during treatment and for a few months after treatment is over.
Interferon may affect your ability to have children. In women, it may affect the menstrual
cycle. In men, it may lower the sperm count.
You should not have any vaccinations while you are having interferon treatments or for 3
months after you have finished your treatment.
Tell your doctor if you have a history of heart disease as you may be at greater risk for
complications. If you have shingles or have recently been exposed to chicken pox, Interferon
may cause a flare up.
Keep the medicine in the refrigerator until just before you use it.
You will be shown how to mix the drug and give an injection. The nursing staff in the clinic
will help you with this.
Do not take aspirin or aspirin-like products (ibuprofen) or corticosteroids while receiving
Interferon. These drugs alter the effects of Interferon.
