The US brand name of Vorinostat is Zolinza.
Vorinostat is a chemotherapy drug used in the treatment of T-cell lymphoma (CTCL), a form of cancer that attacks certain white blood cells, causing lesions to form on the sufferer’s skin.
Vorinostat works by disrupting the growth of the cancerous cells, allowing the body to destroy and remove them. Unfortunately, Vorinostat can also affect the growth of the body’s normal, healthy cells and is known to cause some unwanted side effects. Some of these side effects can be serious and should be reported immediately to your health professional. Other effects are more of a nuisance than a concern, and may not become evident until some months or years following the use of the medicine.
Before beginning treatment with Vorinostat, it is advisable to discuss the pros and cons of using Vorinostat with your doctor. Vorinostat is only available in capsule form through a prescription from your medical professional.
Together with its desired effects, some medicines can cause some unwanted effects too. Not all of these side-effects will affect every patient, but if they occur, they may require medical attention.
The side effects commonly experienced by patients taking Vorinostat include cracks in the skin, scaliness, and itching. Your skin may also become reddened and swollen in patches. You may also find that your sense of taste has changed, and you could find that you are no longer able to register the flavor of certain foods, and your mouth may become unusually dry.
You may become constipated, and you could find that you experience some hair loss or thinning of your hair. It is not uncommon for people taking Vorinostat to find that they suffer from a loss of physical strength and intermittent muscle spasms. Some people find that they struggle to keep warm.
These effects are quite common and should not be a cause for immediate alarm, although you should mention them to your doctor.
Other, less common side effects can sometimes include feelings of anxiety and confusion accompanied by dizziness and fainting. You may find that you experience bloating of your face and extremities, chest pain or coughing. You could feel as though you have the flu, with head and muscle aches, pains, chills or a fever. Some people suffer from diarrhea or black, tarry stools, and urination may become very frequent and painful. You could feel that your heart is beating too fast or irregularly. You may feel unusually thirsty and find that you have a reduced appetite. Swellings can appear on your face, extremities, and sexual organs, and you may experience a tingling feeling or numbness in these areas.
Many of the milder side effects that you may experience when you begin taking Vorinostat will disappear without further medical attention, as your body adjusts to the new drug. Your doctor will be able to advise you on ways to reduce or prevent many of the side effects. However, if you find that the unpleasant effects persist and are causing you problems, always consult your medical professional. Not all the recognized side-effects of Vorinostat affect patients, and some people may experience other unpleasant effects. If you notice any other effects, always check with your doctor or seek medical advice from another health professional.
