NKDA – No Known Drug Allergy

Allergies are a major concern for health professionals, whether in the context of hospital care or doctor visits. Serious errors, sometimes very serious, can occur if allergies are not detected before the surgical procedure or even simple treatment, which is the in-office treatment of an infection.

Allergic Diseases

Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to substances that are not harmful to the environment. Adverse drug reactions (ADR) are defined as any harmful or unintended reactions to a drug that occurs in doses used for prevention, diagnosis, or treatment. ADRs are common in daily clinical practice, affecting between 15 and 25% of patients; severe reactions occur in 7-13% of patients.

Drug allergies are one of the most common reactions of the drug, including the spectrum of immunologically mediated hypersensitivity in various forms and clinical presentations. It accounts for about 5-10% of all ADRs. Excessive pseudo reactions (also known as non-allergic reactions) indicate another type of unexpected ADR. These reactions are often clinically indistinguishable from an autoimmune reaction, but there is no specific definition. Allergies to drugs not only affect a patient’s health, but can also lead to delayed treatment, the use of alternative therapies, unnecessary investigations, increased morbidity, and even death.

As a result, hospitals and other health care facilities have taken steps to improve the early detection of known drug-resistant drugs in their patients. Today, hospitalized patients must take a diet that includes listing any known allergies they may have. These are included in the person’s medical records and are generally shared with the treating physician and any other professional involved.

If you see a doctor for the first time or are about to have surgery, be aware of your chart or medical file that will usually include the abbreviation “NKA” or “NKDA.” NKA is an acronym for “No Known Allergies,” meaning that no known allergies of any kind. In contrast, the NKDA stands for “No known drug allergies.” So as a patient, if you see any of these comments or summaries in your medical or hospital file, and you know that is not the case, please speak and let your healthcare provider know what diseases you have such as this that actually saves your life.

Summary: Allergic diseases are some conditions caused by hypersensitivity of the immune system to typically substances that are harmless in the environment.

Common Drug Allergies

While any drug can create an allergic reaction, there are some common drug allergies that are more likely than others. These include:
:black_small_square: Antibiotics, like penicillin.
:black_small_square: Sulfonamides, both antibiotic and non-antibiotic.
:black_small_square: Aspirin and Non-Steroidal Anti-Inflammatories (NSAIDs) Ibuprofen.
:black_small_square: Anti-seizure medications like Lamictal
:black_small_square: Chemotherapy drugs
:black_small_square: Monoclonal antibody therapies, like Rituxan rituximab)

Reactions may vary from person to person, with some developing severe rashes while others begin to have shortness of breath and develop facial swelling. For those who have responded in the past, repetition increases the chances of a more difficult response, increasing with each recurring exposure.


Some may also have a condition called anaphylaxis, a life-threatening allergic reaction that involves the whole body. Symptoms may appear within seconds and include things like hives, swelling of the face, fluid in the lungs, a dangerous lowering of blood pressure, and shock. Anaphylaxis is an overdose that occurs immediately when it starts and can cause death. It often causes more than one of the following: a violent rash, sore throat or swelling of the tongue, shortness of breath, vomiting, lightheadedness, low blood pressure. These symptoms usually last more than minutes to hours.


The main treatment for anaphylaxis is an intravenous epinephrine injection, intravenous fluid, and flattening, additional doses of epinephrine may be needed. Other measures, such as antihistamines and steroids, are compatible. In addition, if a person experiences anaphylaxis, they will be at risk if they are exposed to the same drug or the same thing.

As a result, administration of epinephrine autoinjector and screening in relation to this condition is recommended for people with a history of anaphylaxis. Anaphylaxis can occur by responding to almost any external substance. Common causes include toxins from insect bites or stings, food, and medicine. Food is the most common cause in children and young adults while medication and insect bites and bees are more common in older adults.

:small_blue_diamond: Allergy vs. Intolerance?

An allergy is defined as something that causes an immune response that affects many organs in the body. Intolerance is defined as the inability to tolerate the side effects of a drug or food. Examples would be stomach problems, nausea, or diarrhea. None of this has a real immune system response. Any simple way to tell if you have an allergy or you are intolerant is to try an antihistamine test. This is where you use a product like diphenhydramine, generic Benadryl.

Take a low dose of 25mg 30 minutes before taking the medicine you think is allergic to it. If your symptoms are not so bad you may not have been allergic, but if they are the same you may not be tolerant. Diphenhydramine is very reasonably priced.

You may have allergies to a drug, but if you really feel nauseous when you take it then it is not really an allergy. For many medications, you can do things to prevent these types of intolerance. Working with your doctor and pharmacist to manage this intolerance can help you get the treatment you need without side effects.

:small_blue_diamond: Save money by using drugs you are intolerant to?

Most of the time patients will try the drug without getting proper instructions on how to take the medication. This can lead to those drugs being listed as allergic. Therefore, unavailability to treat your disease. It was seen many times when patients were not instructed to take the medication with food. When this happens, the other drug chosen to treat the disease is usually more expensive.

:small_blue_diamond: Do your allergies all match?

How do you know if your allergies are noted? You need to verify what your doctors and pharmacists have in your file.

Primary care physician: NDKA

Cardiologist: upset stomach with Digoxin

Pharmacist: Latex allergy

Outpatient surgery center: Nut Disorders

As you can see from the example everyone needs to know about latex allergy so that you do not end up having a bad experience during surgery.

:small_blue_diamond: NKA is not suitable due to allergies to peanuts and latex.

NKDA may be good for you because Digoxin is by no means an allergy, but rather an intolerance. You need to make sure everyone gets this well-marked. Correcting errors in your medical file can prevent side effects.

:small_blue_diamond: Allergies can change over time

Allergies can develop at any time. You may experience effects as soon as you ingest them and it may take years to appear after taking something other than the drug. Allergies can also go away or lessen over time, and before you try this idea consult your doctor.

The reason is that over time your immune system can change as you grow older and develop various diseases. So be sure to keep in mind what NDKA and NKA mean as things can change.

The first time you take this drug you may not notice any symptom of allergy. However, after you start taking the drug your immune system produces antibodies in that drug. Antibodies are how the immune system recognizes a drug or other allergy and attacks it. Second, when you take medication, your antibodies are ready to attack.

So, you can have an allergy to the second or third dose. This is especially true of injectable drugs that you can take once a week or once a month.
