Cyclosporine is available in its original form and as another product that has been modified (changed) so that the medication can be better absorbed in the body. Original cyclosporine and cyclosporine (modified) are absorbed by the body in different amounts, so they cannot be substituted for one another. Take only the type of cyclosporine that was prescribed by your doctor. When your doctor gives you a written prescription, check to be sure that he or she has specified the type of cyclosporine you should receive. Each time you have your prescription filled, look at the brand name printed on your prescription label to be sure that you have received the same type of cyclosporine. Talk to your pharmacist if the brand name is unfamiliar or you are not sure you have received the right type of cyclosporine.

Taking cyclosporine or cyclosporine (modified) may increase the risk that you will develop an infection or cancer, especially lymphoma (cancer of a part of the immune system) or skin cancer. This risk may be higher if you take cyclosporine or cyclosporine (modified) with other medications that decrease the functioning of the immune system such as azathioprine (Imuran), cancer chemotherapy, methotrexate (Rheumatrex), sirolimus (Rapamune), and tacrolimus (Prograf). Tell your doctor if you are taking any of these medications, and if you have or have ever had any type of cancer. To reduce your risk of skin cancer, plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen during your treatment. If you experience any of the following symptoms, call your doctor immediately: sore throat, fever, chills, and other signs of infection; flu-like symptoms; coughing; difficulty urinating; pain when urinating; a red, raised, or swollen area on the skin; new sores or discoloration on the skin; lumps or masses anywhere in your body; night sweats; swollen glands in the neck, armpits, or groin; trouble breathing; chest pain; weakness or tiredness that does not go away; or pain, swelling, or fullness in the stomach.

Cyclosporine and cyclosporine (modified) may cause high blood pressure and kidney damage. Tell your doctor if you have or have ever had high blood pressure or kidney disease. Also tell your doctor if you are taking any of the following medications: amphotericin B (Amphotec, Fungizone); cimetidine (Tagamet); ciprofloxacin (Cipro); colchicine; fenofibrate (Antara, Lipophen, Tricor); gemfibrozil (Lopid); gentamicin; ketoconazole (Nizoral); melphalan (Alkeran); nonsteroidal anti-inflammatory drugs such as diclofenac (Cataflam, Voltaren), naproxen (Aleve, Naprosyn), and sulindac (Clinoril); ranitidine (Zantac); tobramycin (Tobi); trimethoprim with sulfamethoxazole (Bactrim, Septra); and vancomycin (Vancocin). If you experience any of the following symptoms, call your doctor immediately: dizziness; swelling of the arms, hands, feet, ankles, or lower legs; fast, shallow breathing; nausea; or irregular heartbeat.

If you have psoriasis, tell your doctor about all the psoriasis treatments and medications you are using or have used in the past. The risk that you will develop skin cancer is greater if you have ever been treated with PUVA (psoralen and UVA; treatment for psoriasis that combines an oral or topical medication with exposure to ultraviolet A light); methotrexate (Rheumatrex) or other medications that suppress the immune system; UVB (exposure to ultraviolet B light to treat psoriasis); coal tar; or radiation therapy. You should not be treated with PUVA, UVB, or medications that suppress the immune system while you are taking cyclosporine (modified) to treat psoriasis.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body’s response to cyclosporine or cyclosporine (modified).

Cyclosporine and cyclosporine (modified) are used with other medications to prevent transplant rejection (attack of the transplanted organ by the immune system of the person who received the organ) in people who have received kidney, liver, and heart transplants. Cyclosporine (modified) is also used alone or with methotrexate (Rheumatrex) to treat the symptoms of rheumatoid arthritis (arthritis caused by swelling of the lining of the joints) in patients whose symptoms were not relieved by methotrexate alone. Cyclosporine (modified) is also used to treat psoriasis (a skin disease in which red, scaly patches form on some areas of the body) in certain patients who have not been helped by other treatments. Cyclosporine and cyclosporine (modified) are in a class of medications called immunosuppressants. They work by decreasing the activity of the immune system.

Cyclosporine and cyclosporine (modified) both come as a capsule and a solution (liquid) to take by mouth. Cyclosporine is usually taken once a day. Cyclosporine (modified) is usually taken twice a day. It is important to take both types of cyclosporine on a regular schedule. Take cyclosporine or cyclosporine (modified) at the same time(s) each day, and allow the same amount of time between doses and meals every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cyclosporine or cyclosporine (modified) exactly as directed. Do not take more or less of the medication or take it more often than prescribed by your doctor.

Your doctor will probably adjust your dose of cyclosporine or cyclosporine (modified) during your treatment. If you are taking either type of cyclosporine to prevent transplant rejection, your doctor will probably start you on a high dose of the medication and gradually decrease your dose. If you are taking cyclosporine (modified) to treat rheumatoid arthritis or psoriasis, your doctor will probably start you on a low dose of the medication and gradually increase your dose. Your doctor may also decrease your dose if you experience side effects of the medication. Tell your doctor how you are feeling during your treatment.

Cyclosporine (modified) helps control the symptoms of psoriasis and rheumatoid arthritis, but does not cure these conditions. If you are taking cyclosporine (modified) to treat psoriasis, it may take 2 weeks or longer for your symptoms to begin to improve, and 12 to 16 weeks for you to feel the full benefit of the medication. If you are taking cyclosporine (modified) to treat rheumatoid arthritis, it may take 4 to 8 weeks for your symptoms to improve. Continue to take cyclosporine (modified) even if you feel well. Do not stop taking cyclosporine (modified) without talking to your doctor. Your doctor may decrease your dose gradually.

You may notice an unusual smell when you open a blister card of cyclosporine capsules. This is normal and does not mean that the medication is damaged or unsafe to use.

Cyclosporine (modified) oral solution may gel or become lumpy if it is exposed to temperatures below 68 °F (20 °C). You can use the solution even if it has gelled, or you can turn the solution back to a liquid by allowing it to warm to room temperature (77 °F [25 °C]).

Cyclosporine and cyclosporine (modified) oral solution must be mixed with a liquid before use. Cyclosporine (modified) oral solution may be mixed with orange juice or apple juice but should not be mixed with milk. Cyclosporine oral solution may be mixed with milk, chocolate milk, or orange juice. You should choose one drink from the appropriate list and always mix your medication with that drink.

To take either type of oral solution, follow these steps:

• Fill a glass (not plastic) cup with the drink you have chosen.
• Remove the protective cover from the top of the dosing syringe that came with your medication.
• Place the tip of the syringe into the bottle of solution and pull back on the plunger to fill the syringe with the amount of solution your doctor has prescribed.
• Hold the syringe over the liquid in your glass and press down on the plunger to place the medication in the glass.
• Stir the mixture well.
• Drink all of the liquid in the glass right away.
• Pour a little more of the drink you have chosen into the glass, swirl the glass around to rinse, and drink the liquid.
• Dry the outside of the syringe with a clean towel and replace the protective cover. Do not wash the syringe with water. If you do need to wash the syringe, be sure that it is completely dry before you use it to measure another dose.

Cyclosporine and cyclosporine (modified) are also sometimes used to treat Crohn’s disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, and fever) and to prevent rejection in patients who have received pancreas or cornea transplants. Talk to your doctor about the possible risks of using this medication for your condition.

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

• Tell your doctor if you are pregnant or plan to become pregnant. If you become pregnant while taking either type of cyclosporine, call your doctor. Both types of cyclosporine may increase the risk that your baby will be born too early.
• Tell your doctor if you are breast-feeding or planning to breast-feed.
• Do not have vaccinations without talking to your doctor.
• You should know that cyclosporine may cause growth of extra tissue in your gums. Be sure to brush your teeth carefully and see a dentist regularly during your treatment to decrease the risk that you will develop this side effect.

Keep this medication in the container it came in, tightly closed and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Do not store this medicine in the refrigerator and do not freeze it. Dispose of any remaining solution 2 months after you first open the bottle.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.

Symptoms of overdose may include:

• Yellowing of the skin or eyes
• Swelling of the arms, hands, feet, ankles, or lower legs.
