Why isn't everyone with vitiligo on the oral medication? Can I order it and get it sent to Australia?

Rafti hello! Ruxolitinib is used in adults to treat myelofibrosis or polycythemia vera, which are bone marrow disorders that affect your body's ability to produce blood cells. Ruxolitinib is also used to treat graft versus host disease in adults and children at least 12 years old. Ruxolitinib is usually given after other treatments have failed.
I sugguest to get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat. Some side effects may be similar to the symptoms of myelofibrosis. Call your doctor at once if you have:

1) changes in the size, shape, or color of a mole or skin lesion.

2) problems with speech, thought, vision, or muscle movement (these symptoms may start gradually and get worse quickly).

3) nausea, vomiting, weakness, general ill feeling.

4) cold sores around your mouth, skin sores or blisters, itching, tingling, skin rash, burning pain in your thigh or lower back.

5) pain in your arms, back, neck, jaw, or stomach.

6) signs of a stroke--sudden numbness or weakness, severe headache, slurred speech, problems with vision or balance.

7) signs of a blood clot in the lung--chest pain, sudden cough or shortness of breath, dizziness, coughing up blood.

8) signs of a blood clot deep in the body--pain, swelling, or warmth in one leg.

9) heart attack symptoms--chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating.

10) signs of infection--fever, chills, sore throat, body aches, unusual tiredness, loss of appetite, bruising or bleeding.

11) low blood cell counts--fever, chills, tiredness, mouth sores, skin sores, easy bruising, unusual bleeding, pale skin, cold hands and feet, feeling light-headed or short of breath.

12) signs of tuberculosis: fever, cough, night sweats, loss of appetite, weight loss, and feeling very tired.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
