What Are Some Home Remedies for Poison Ivy Blisters?

Home remedies for poison ivy blisters include flooding the area with warm water for 20 to 30 minutes or using rubbing alcohol on the blisters, says MedicineNet. Plant washes, soaps or detergents that can cut through the poison ivy's oily resin can also be used. The patient's clothes also need to be laundered before they're worn again.

The patient should also be careful to clean under her fingernails to remove the resin, says MedicineNet. After the area is washed, cool compresses and calamine lotion or antihistamines are used to soothe the itching. Oatmeal baths, Benadryl and Domeboro solution also ease the itch of poison ivy. If the patient experiences pain, she can take over-the-counter pain medications.

These treatments are usually enough for a normal case of poison ivy, says MedicineNet. The rash usually goes away in a week or two anyway. However, some people who have a very bad rash may need to have stronger medications such as corticosteroids prescribed for them by a medical professional. Antibiotics may need to be prescribed if the rash becomes infected.

A patient who has or has had an anaphylactic reaction after coming into contact with poison ivy needs immediate medical attention, says MedicineNet. The reaction can interfere with the patient's ability to breathe or swallow.
