Iressa review





Cancer is obviously a life-altering disease. It has kept a lot of people from enjoying life, reducing them from thinking about dying all the time. For the most part, cancer is associated directly with death. But that should not be the case. Many cancer patients have succeeded in their fight against the disease. With the help of updates in medical technology along with revolutionary drugs, cancer patients have become hopeful more than ever.

Iressa is one cancer drug that has been making significant changes in lung cancer patients’ lives. It is used to prevent different kinds of lung cancer cells from growing, multiplying, and causing harm in one’s body. Iressa does it by blocking the activation of the enzyme that is responsible for the growth of cells including the cancerous ones.

Iressa is a prescription drug given to lung cancer patients as a stand-alone treatment in case the disease did not respond to chemotherapy. This drug provides a good promise of reducing the size of the cancer cells substantially but sadly, like other cancer medications, it cannot promise full recovery.

Iressa should not be used with warfarin. This drug may increase the risk of unusual bleeding when used along with Iressa. Aside from warfarin, there are other drugs that are contraindicated with Iressa including fluconazole, clarithromycin, ketoconazole, and nelfinivir among others. Doctors also recommend a dosage adjustment of Iressa when taken with grape fruit juice.

Iressa has also been found unsafe to be used in pregnant and lactating women. The possibility of toxicity is high.

Before taking an Iressa prescription, you must also discuss any other lung ailment, allergies, and kidney disorders with your doctor. Your medical history speaks a lot on how Iressa can affect your health.

Iressa is prescribed to be taken alone as the anti-cancer drug. Only a 250mg per day dose is recommended. Increasing the dosage of the drug does not provide a greater positive response instead poses a higher level of toxicity.

You must take your medicine at the same time each day to avoid missing a dose. If that happens, you must take Iressa as soon as you remember and only if it is not too close to your next dose. Otherwise, you will have to discard that missed dose and continue with your dosing schedule.

As mentioned above, overdosing on Iressa results to an increased toxicity. If overdose occurs, contact your doctor immediately. Drug overdose in this case can be identified with skin rash and severe and persistent diarrhea.

Iressa can be taken with or without meals.

Iressa causes common side effects such as diarrhea, nausea, vomiting, and appetite loss. However, patients taking the drug must be closely observed for the persistence of such symptoms. Those side effects may worsen and pose great discomfort to the patient.

In some cases, Iressa has also been found to cause a serious lung condition, which is basically about an inflammation within the lung area. To ensure that you are safe from such a side effect, you must submit yourself for regular clinical and laboratory tests. Rush to your doctor immediately, especially if breathing difficulty, severe coughing, and fever occur.
