eously upon discontinuation of cyclosporine. There were four cases of benign lymphocytic infiltration: 3 regressed spontaneously upon discontinuation of cyclosporine, while the fourth regressed despite continuation of the drug. The remainder of the malignancies, 13 cases (0.9%), involved various organs.
Patients should not be treated concurrently with cyclosporine and PUVA or UVB, other radiation therapy, or other immunosuppressive agents, because of the possibility of excessive immunosuppression and the subsequent risk of malignancies (see CONTRAINDICATIONS). Patients should also be warned to protect themselves appropriately when in the sun, and to avoid excessive sun exposure. Patients should be thoroughly eva luated before and during treatment for the presence of malignancies remembering that malignant lesions may be hidden by psoriatic plaques. Skin lesions not typical of psoriasis should be biopsied before starting treatment. Patients should be treated with Gengraf (cyclosporine oral solution, USP [MODIFIED]) only after complete resolution of suspicious lesions, and only if there are no other treatment options (see Special Monitoring for Psoriasis Patients).
PRECAUTIONS
General
Hypertension
Cyclosporine is the active ingredient of Gengraf (cyclosporine oral solution, USP [MODIFIED]). Hypertension is a common side effect of cyclosporine therapy which may persist (see ADVERSE REACTIONS and DOSAGE AND ADMINISTRATION for monitoring recommendations). Mild or moderate hypertension is encountered more frequently than severe hypertension and the incidence decreases over time. In recipients of kidney, liver, and heart allografts treated with cyclosporine, antihypertensive therapy may be required (see Special Monitoring of Rheumatoid Arthritis and Psoriasis Patients). However, since cyclosporine may cause hyperkalemia, potassium-sparing diuretics should not be used. While calcium antagonists can be effective agents in treating cyclosporine-associated hypertension, they can interfere with cyclosporine metabolism (see PRECAUTIONS - Drug Interactions).
Vaccination
During treatment with cyclosporine, vaccination may be less effective; and the use of live attenuated vaccines should be avoided.
Special Monitoring of Rheumatoid Arthritis Patients
Before initiating treatment, a careful physical examination, including blood pressure measurements (on at least two occasions) and two creatinine levels to estimate baseline should be performed. Blood pressure and serum creatinine should be eva luated every 2 weeks during the initial 3 months and then monthly if the patient is stable. It is advisable to monitor serum creatinine and blood pressure always after an increase of the dose of nonsteroidal anti-inflammatory drugs and after initiation of new nonsteroidal anti-inflammatory drug therapy during Gengraf (cyclosporine oral solution, USP [MODIFIED]) treatment. If coadministered with methotrexate, CBC and liver function tests are recommended to be monitored monthly (see also PRECAUTIONS- General, Hypertension).
In patients who are receiving cyclosporine, the dose of Gengraf should be decreased by 25%-50% if hypertension occurs. If hypertension persists, the dose of Gengraf should be further reduced or blood pressure should be controlled with antihypertensive agents. In most cases, blood pressure has returned to baseline when cyclosporine was
