The best defence and cure for poison ivy is, of course, to avoid it, so learn how to recognize the plants and be aware that they can grow as vines or shrubs. They can be spotted by their characteristic cluster of three pointed leaves. The leaves are shiny and the berries are green/yellow in color. Recognition is of particular importance for those people who love to be out in the countryside, camping and hiking. As a regular camper and hiker, you should already know that going into the great outdoors makes you fair game for a myriad of stinging insects as well as noxious plants like the poison ivy. If you are uncertain as to whether you will come across the plant or not, wear protective clothing, and if you are caught off guard, try to rinse off the affected area as quickly as possible to rid yourself of the plant’s toxic resin.
In patients with the adrenogenital syndrome , a single intramuscular injection of 40 mg every two weeks may be adequate. For maintenance of patients with rheumatoid arthritis , the weekly intramuscular dose will vary from 40 to 120 mg. The usual dosage for patients with dermatologic lesions benefited by systemic corticoid therapy is 40 to 120 mg of methylprednisolone acetate administered intramuscularly at weekly intervals for one to four weeks. In acute severe dermatitis due to poison ivy, relief may result within 8 to 12 hours following intramuscular administration of a single dose of 80 to 120 mg. In chronic contact dermatitis, repeated injections at 5 to 10 day intervals may be necessary. In seborrheic dermatitis, a weekly dose of 80 mg may be adequate to control the condition.
