Treatment for angioedema depends on the cause.
This article discusses treatment options for angioedema.
It covers lifestyle changes, over-the-counter (OTC) and prescription drugs, surgeries, and complementary treatments.
Verywell
There are also many people who have spontaneous angioedema, meaning no external trigger is associated with the episode.
Sometimes an allergy test can help in identifying the substance that is causing your reaction.
Be sure not to spend more than a few minutes in cold water.
These medications are taken orally.
In general, non-sedating antihistamines likecetirizine, which don’t cause drowsiness, are preferred over sedating versions likediphenhydramineandhydroxyzine.
Prescriptions
You might need prescription medications if you have recurrent angioedema or if your symptoms are severe.
Epinephrine
Epinephrine is a powerful medication that suppresses the immune system more quickly than steroids and antihistamines.
They will teach you or a family member how to do this.
However, there are rare circumstances in which you could need special procedures if your breathing is affected.
This hole will be surgically repaired after you recover.
Vitamins
Vitamins have been recommended for the prevention and treatment of angioedema, with little solid evidence.
In particular,vitamin Cis claimed to lower histamine levels, although there is very little scientific proof.
Vitamin B12 injections have also been studied as a possible treatment to reduce the frequency of recurring angioedema attacks.
But again, there is not a lot of evidence.
Herbs
Herbs have long been used in traditional medicine for treating diseases.
But just because they are natural, doesn’t mean they are always safe.
Another well-known herb,chamomile, has traditionally been used to soothe hives.
Chamomile is also known to interact with estrogen and birth control medications.
Summary
The first step to treating and preventing angioedema is to identify the cause.
Once identified, known triggers need to be avoided.
Your doctor may recommend or prescribe oral antihistamines to block the immune response that causes angioedema.
In very severe cases, specialist-driven procedures may be necessary to help you breathe during an angioedema episode.
Keeping a consistent journal may help you and your healthcare provider see a pattern and ultimately identify the trigger.
