What Is A Medication Allergy

RASH AFTER ANTIBIOTICS!!! (Is this an Allergic Reaction?) | Dr

A true allergic reaction to medication occurs when the immune system is activated in response to a drug. The medication can be taken by mouth, injected into the body or rubbed on the skin. The symptoms from an allergic reaction vary from a mild skin rash to sudden swelling of many body parts with life threatening fall in blood pressure.

Most people with a drug allergy have been exposed to that drug or a similar drug before. During the earlier exposure, immune cells formed antibodies against the drug. Antibodies are proteins created by the immune system to battle foreign invaders such as bacteria and viruses. When a person is exposed to the drug again, the antibodies go into action, setting off the allergic response. The symptoms of drug allergy may happen immediately or after taking the drug for a week or more.

The reason a person develops a particular drug allergy is usually unknown, but genetics probably play a significant role.

Drug allergies can pose a significant problem, not only because of the symptoms they cause, but also because they can prevent or hinder the use of the more effective medications to treat medical conditions.

For many, medication allergies go undetected until they take a drug and have an allergic reaction.

How Do You Treat An Amoxicillin Rash

If your child develops hives, you can treat the reaction with over-the-counter Benadryl, following age-appropriate dosing instructions. Dont give your child any more antibiotics until a doctor sees your child.

If your child has a rash other than hives, you can also treat them with Benadryl if theyre itching. You should check with your doctor before giving any more of the antibiotic, just to rule out the chance of an allergic reaction.

Unfortunately, rashes are one of those symptoms that can be very confusing. A rash could mean nothing. Or, a rash could mean that your child is allergic to amoxicillin. Any allergy can be very serious quickly, and even put your child at risk for death.

The Characteristics Of Amoxicillin Rash

An allergic reaction to amoxicillin can be in the form of hives. What exactly are hives? They are raised and itchy bumps that can be white to red in color. If you notice hives after a dose of amoxicillin, then theyre definitely an allergy to amoxicillin.

Another type of rash is maculopapular rash, which could appear later on. The typical characteristics are red and flat patches on the skin. It usually occur several days after taking amoxicillin. The rash typically appears in a symmetrical fashion and usually affects the trunk. The rashes can spread to other parts of the body such as the arms, legs, and face.

Treatment For Penicillin Allergies

The somewhat obvious first step for someone suffering from a penicillin allergy is to avoid the antibiotic altogether. To treat the immediate symptoms, your doctor may prescribe a strong antihistamine or you can take an over the counter variety. More adverse reactions may require the use of corticosteroids which are either taken orally or injected by a physician. In the most extreme reactions, medical personnel will inject a patient with epinephrine to counteract the symptoms of anaphylaxis.

Is The Amoxicillin Rash Dangerous

An amoxicillin rash by itself is not dangerous. But if the rash is being caused by an allergy, the allergy could be dangerous to your child. Allergic reactions tend to get worse the more the allergen is exposed.

When Should I Get Tested

I am often asked to evaluate penicillin allergies when a patient needs penicillin or another beta-lactam, and the documented allergy is obstructing the best treatment. However, the best time to have a penicillin allergy evaluated is when youre healthy.

You can discuss allergies as part of routine health maintenance with a primary care doctor or pediatrician. Clarifying medication allergies is also a good idea before an operation a penicillin allergy can impact infection risk, and allergies to latex and pain medications can get in the way of a smooth operation and post-operative period. Finally, women of childbearing age who are thinking of conceiving might want to evaluate an allergy to penicillin. Penicillins are used for infections in pregnancy and during deliveries for a variety of reasons. Pregnant patients can also be evaluated safely for a penicillin allergy in their third trimester.

Allergic to Amoxicillin

See a Premier Physician Network provider near you.

Allergic reactions to antibiotics are something you can develop over time. They might not affect you the first time you take a medication. Or, you could have been allergic to a medication in the past, but forgotten before you take it again.

Either way, antibiotics are the most common cause of life-threatening immune-medicated drug reactions, according to the National Institutes of Health.

If you take an antibiotic and think youre having an allergic reaction, the first step is to know the difference between medication side effects and an actual allergy.

Side effects could be an upset stomach, diarrhea, nausea, and possibly a skin rash if youve been out in the sun. An allergic reaction is a little more serious. In an allergic reaction, you can have things such as hives, itching, and a skin rash.

An antibiotic allergy can develop into something more severe an anaphylactic reaction. This can cause:

  • Drop in blood pressure
  • Rapid heartbeat
  • Shortness of breath

If you have any of these reactions, seek medical attention right away, because they could become more severe.

While an allergic reaction can happen right away or within just a couple hours of taking an antibiotic, it also can take up to two weeks after finishing the medicine. So, make sure to get medical help if you have any allergy symptoms during or within a couple weeks after antibiotic use.

What Is An Allergic Reaction

What are Hives? | Family Allergy and Asthma

Allergic or hypersensitive reaction is excessive sensitivity exhibited by your immune system to a conventionally harmless substance such as pollen, dust and certain foods. These substances are not dangerous in the majority of the people, but when they trigger allergic reactions, they are called allergens. Allergic reactions occur when the allergens contact the skin, are inhaled, swallowed or injected.

Allergic reactions are quite common and may happen seconds to hours after contact with the allergen. Though many allergic reactions are mild, others may be dangerous or life-threatening. They may be localized, involving a small part of the body or may affect a large area orthe whole body.

One example of such a reaction is the rash associated with certain metal jewellery or footwear, or the application of certain cosmetics. Such rash is called contact dermatitis.

Sometimes people with allergies sneeze uncontrollably on exposure to dust or pollen. This is called allergic rhinitis

An allergic reaction begins with touching, inhaling or swallowing an allergen. In response to this trigger, the body starts making a type of protein called IgE or immunoglobulin E. IgE leads to the release of some chemicals in the body. These chemicals cause the inflammatory symptoms of allergic reactions such as rash, itching and sneezing.
