DRUG ALLERGY - Symptoms, Cause, Risk Factors, Diagnosis, Treatment and Prevention

Understanding Of Drug Allergy

Drug allergy is an overreaction of the immune system against certain drugs you use. This condition is different from the side effects of drugs that are generally listed on the packaging of a drug overdose or poisoning.
In general, drug allergies occur because the immune system trying to fight certain substances contained in the drug. This happens because the immune system considers the drug as a substance that can harm the body.

Drug Allergy Symptoms

Allergic drug reactions usually occur gradually as the immune system build antibodies against the drug. This reaction may not appear immediately when first using the drug.
At this stage of the first use, the immune system will assess the drug as a substance harmful to the body then develops antibodies slowly. In subsequent use, these antibodies will detect and attack the substance of the drug. It is this process that could trigger symptoms of drug allergy.
Most allergy medications have mild symptoms and will usually subside within a few days after you stop taking the drug. Here are some common symptoms of allergy medications that you can look.
  • Rash or bumps on the skin.
  • Itchy.
  • A runny nose.
  • Coughing .
  • Fever .
  • Shortness of breath or shortness of breath.
  • Itchy or watery eyes.
  • Swelling.
However, a severe allergic reaction can also trigger anaphylaxis (allergic reaction that causes malfunction widely body). This condition is very serious and can be fatal and require treatment as soon as possible.
Beware if you are having an allergic reaction. Consult soon yourself to the doctor to determine the cause so it can be avoided.

Drug Anything Can Cause Allergic Reactions?

Almost all drugs can trigger unwanted reactions of the body, but not all reactions including allergies. Drug allergies are caused by the immune system reaction on certain drugs. Several types of drugs that could potentially trigger an allergic reaction include:
  • Antibiotics (eg, penicillin).
  • Non-steroidal anti-inflammatory.
  • Aspirin.
  • Corticosteroid creams or lotions.
  • Anticonvulsants.
  • Insulin.
  • Vaccine.
  • Medicines for hyperthyroidism.
  • As well as drugs for chemotherapy or HIV.

Factors Increase Risk of Drug Allergy

Not everyone will experience drug-induced allergic reactions. Experts suspect there are some factors that can increase a person's risk of allergies to the drug. These risk factors include:
  • Increased exposure to certain drugs , such as the use of repeated, prolonged, or at high doses.
  • Heredity . Your risk for experiencing drug allergies increases if anyone in your family have allergies to certain drugs.
  • Never experienced other types of allergies , such as food allergies.
  • Are allergic to other drugs . For example, if allergic to penicillin, you also have the potential to have allergies to amoxicillin.
  • Disease that causes the body vulnerable to drug allergic reactions , such as HIV.

Drug Allergy Diagnosis Process

Just like any other disease, early stage diagnosis of drug allergy is to check your health and physical condition. Especially, when the appearance of symptoms, the type of drug used, and the severity and changes in the symptoms experienced. If necessary, your doctor may also recommend a detailed examination to confirm the diagnosis, for example:
  • The skin test . Drugs suspected of causing allergies will be applied to the skin with needles, injections or patches. A positive result showed redness, itching, or blisters. If that happens, you almost certainly have an allergy to the drug.
  • Blood tests . This test is rarely used because of the level of accuracy is very limited on drug allergies. But if doctors suspect there will be a severe reaction when skin tests performed on you, then your doctor may do a blood test. These tests also serve to determine other conditions that could lead to the symptoms you are experiencing.

Step Treatment and Prevention on Drug Allergy

Main handling for allergy remedy is to overcome and ease the symptoms experienced. This step can be done to stop consuming or using drugs that cause allergies.
Antihistamines may be advised to block the chemical elements of the immune system which enabled the body during an allergic reaction. The use of corticosteroids can treat inflammation due to allergic reactions are more serious.
For those who experience anaphylaxis, patients need to be treated immediately with epinephrine injection. Patients also should undergo treatment at the hospital in order to get help breathing and stabilize blood pressure.
In addition to treating, we can also prevent the emergence of drug allergy. A major step in preventing drug allergy is to avoid the source of allergy medication. For example, by wearing a bracelet or necklace markers of allergy if possible, tell your doctor or medical personnel about the types of medications that can trigger allergic reactions in you. If there are any anaphylactic reactions or severe allergic reaction to a drug, doctors may prescribe an injection of epinephrine. Carry a precaution in case of a similar reaction.
