Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include: coal tar, orlistat, other drugs that weaken the immune system/increase the risk of infection (such as natalizumab, rituximab, tofacitinib), drugs that may increase potassium levels (such as potassium supplements, certain diuretics/"water pills" including amiloride, spironolactone), tacrolimus.
Other medications can affect the removal of cyclosporine from your body, which may affect how cyclosporine works. Examples include bosentan, mifepristone, St. John's wort, ritonavir, among others.
This medication can slow down the removal of other medications from your body, which may affect how they work. Examples of affected drugs include aliskiren, dabigatran, dronedarone, elagolix, resmetirom, certain statins (such as pitavastatin, simvastatin), voxilaprevir, among others.
Negative Interactions
3- Potential Negative Interaction
Cyclosporine
Potassium
Cyclosporine can cause excess retention of potassium, potentially leading to dangerous levels of the mineral in the blood (hyperkalemia). Potassium supplements, potassium-containing salt substitutes (No Salt, Morton Salt Substitute, and others), and even high-potassium foods (primarily fruit) should be avoided by people taking cyclosporine, unless directed otherwise by their doctor.

Cyclosporine
Chinese Scullcap
In a study in rats, oral administration of Chinese scullcap at the same time as cyclosporine significantly reduced the absorption of cyclosporine. Chinese scullcap did not interfere with the availability of cyclosporine when cyclosporine was given intravenously. Because of the potential adverse interaction, people taking cyclosporine should not take Chinese scullcap.

Cyclosporine
St. John’s Wort
Pharmacological research from Europe suggests that St. John’s wort (Hypericum perforatum) may reduce plasma levels of cyclosporine. Two case reports also describe heart transplant patients taking cyclosporine who showed signs of acute transplant rejection after taking St. John’s wort extract. In both cases, reduced plasma concentrations of cyclosporine were found. One report cites similar findings in three patients taking cyclosporine and St. John’s wort together. Finally, similar drops in cyclosporine blood levels were reported in 45 kidney or liver transplant patients who began taking St. John’s wort. Until more is known, people taking cyclosporine should avoid the use of St. John’s wort.

Cyclosporine
Magnesium
Cyclosporine has been associated with low blood magnesium levels and undesirable side effects. Some doctors suggest monitoring the level of magnesium in red blood cells, rather than in serum, as the red blood cell test may be more sensitive for evaluating magnesium status.

Cyclosporine
Vitamin E
Twenty-six liver transplant patients (both adults and children) unable to achieve or maintain therapeutic cyclosporine blood levels during the early post-transplant period were given water-soluble vitamin E in the amount of 6.25 IU/2.2 pounds of body weight two times per day. Addition of vitamin E in the early post-transplant period reduced the required amount of cyclosporine and the cost of cyclosporine therapy by 26%. These results imply that the addition of vitamin E to established cyclosporine therapy allows for a decrease in the amount of cyclosporine. Combining vitamin E and cyclosporine requires medical supervision to avoid cyclosporine toxicity.

Ginkgo
Ginkgo was reported to protect liver cells from damage caused by cyclosporine in a test tube experiment. A Ginkgo biloba extract partially reversed cyclosporine-induced reduced kidney function in a study of isolated rat kidneys. Human trials have not studied the actions of ginkgo to prevent or reduce the side effects of cyclosporine.

Omega-3 Fatty Acids
Several studies have shown that in organ transplant patients treated with cyclosporine, addition of 4–6 grams per day of omega-3 fatty acids from fish oil helped reduce high blood pressure, though not every study has found fish oil helpful. It remains unclear to what extent fish oil supplementation will help people with high blood pressure taking cyclosporine following organ transplant.

Grapefruit
In a randomized study of nine adults with cyclosporine-treated autoimmune diseases, grapefruit juice (5 ounces two times per day with cyclosporine, for ten days) caused a significant increase in cyclosporine blood levels compared with cyclosporine with water. The rise in cyclosporine blood levels was associated with abdominal pain, lightheadedness, nausea, and tremor in one patient. A similar interaction between grapefruit juice and cyclosporine has been observed in healthy volunteers. Using grapefruit juice to reduce the amount of cyclosporine needed has not been sufficiently studied and cannot therefore be counted on to produce a predictable change in cyclosporine requirements. The same effects might be seen from eating grapefruit as from drinking its juice.

Pomegranate
Pomegranate juice has been shown to inhibit the same enzyme that is inhibited by grapefruit juice. The degree of inhibition is about the same for each of these juices. Therefore, it would be reasonable to expect that pomegranate juice might interact with cyclosporine in the same way that grapefruit juice does.

Cyclosporine
Quercetin
In an animal study, oral administration of quercetin (50 mg per 2.2 pounds of body weight) at the same time as cyclosporine decreased the absorption of cyclosporine by 43%. However, in a study of healthy human volunteers, supplementing with quercetin along with cyclosporine significantly increased blood levels of cyclosporine, when compared with administering cyclosporine alone. Because the effect of quercetin supplementation on cyclosporine absorption or utilization appears to be unpredictable, individuals taking cyclosporine should not take quercetin without the supervision of a doctor.
