You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to.

Benefits of Cyclophosphamide

Cancer
Cyclophosphamide helps to treat certain kinds of cancer. It may be used alone or in combination with other medicines to treat cancer in various parts of the body. Cyclophosphamide kills or stops the growth of cancer cells and also prevents the multiplication of cancer cells. It is a potent and very toxic medicine and you should discuss the risks and benefits with your doctor. You should avoid drinking alcohol while having this treatment and drink plenty of water to stay hydrated.

Nephrotic syndrome
Nephrotic syndrome is a kidney disorder that causes your body to pass too much protein in your urine accompanied with excessive swelling over various parts of the body such as around the eyes and in the feet and ankles. Cyclophosphamide works by suppressing the immune system thereby reducing inflammation and swelling that occur in nephrotic syndrome. It reduces the protein in the urine and also helps in getting rid of the extra fluid, thereby relieving the swelling over different parts of the body. This helps to restore the normal kidney function and prevents further damage to the kidneys.
