What exactly is Penicillin allergy?
Simply put, this is an unnecessary, excessive response of our body's immune system to the drug penicillin. The job of our immune system is to protect us by fighting off germs and bacteria that cause disease. But sometimes, this system misunderstands and treats the penicillin that is supposed to help us as an invader, that is, an enemy. Imagine, what is happening here is like our body's defense army (the immune system) declaring war on an allied army (Penicillin) that has come to our aid. This is why allergy symptoms begin to appear.The important thing is that not everyone is allergic to penicillin. Also, although it has some side effects , it is not an allergy. Therefore, it is very important to be aware of this.
What are the symptoms of a penicillin allergy?
The symptoms of a penicillin allergy can come on in a variety of ways. Some appear as soon as an hour after taking the medication. Others may take days to appear. Let's look at these separately. Anaphylaxis - a very severe allergic reaction that requires immediate attention
Anaphylaxis is a rare but life-threatening emergency . If you develop any of these symptoms shortly after taking penicillin, go to the nearest hospital emergency room (ETU) immediately. It is not worth delaying for even a second.| Reaction type | Symptoms that indicate |
|---|---|
| Immediate reactions (within an hour of taking the medicine) | |
| Delayed reactions (after days or weeks) |
|
| Emergency medical attention is needed! |

Late onset severe conditions
Although rare, penicillin allergy can lead to serious complications a few days later. It's good to be aware of these as well.- Serum sickness: A condition characterized by a combination of symptoms such as fever, skin rashes, joint pain, swelling, and nausea.
- Drug-induced anemia: A decrease in the number of red blood cells can cause extreme fatigue, rapid heartbeat, and difficulty breathing.
- DRESS syndrome (Drug reaction with eosinophilia and systemic symptoms): This is a condition that affects the whole body. White blood cells increase, lymph nodes swell.
- Stevens-Johnson syndrome: This is a very severe skin reaction that causes painful blisters and peeling of the skin.

How do you know for sure if this is an allergy?
If you experience any unusual symptoms after taking penicillin, be sure to mention them to your doctor the next time you see him. The doctor will examine you, ask you about your symptoms, and make a decision. Sometimes, tests may be needed to confirm whether it is really an allergy. 1. Skin Test: In this, the doctor will use a very small needle to prick the skin on your arm and place a very small amount of penicillin on it. If you are allergic, you will develop a red, itchy rash that looks like a mosquito bite within about 15 minutes. 2. Next step: If there is no reaction in the first test, a very small dose of penicillin will be injected under the skin. If a rash appears there, it is confirmed that you have an allergy. 3. Challenge Test: If there is no reaction to the above two tests, under the supervision of a doctor, you will be given a very low dose of penicillin to drink. If there are no symptoms after about an hour, the dose is gradually increased to a normal dose. If there is no reaction, it can be confirmed that you are not allergic to penicillin.These tests are always performed in a hospital or clinic under the full supervision of a doctor or trained staff, because any sudden reaction requires immediate treatment.
What to do if you have an allergy?
If you develop allergic symptoms while taking penicillin, stop taking the medicine immediately and call your doctor.- For symptoms such as general itching and hives, the doctor may prescribe an antihistamine (e.g. Piriton).
- For more severe symptoms, such as swelling, a corticosteroid- type medication may be given.
- In case of an emergency such as anaphylaxis, epinephrineThe vaccine is given immediately. The patient is then kept under observation in the hospital until blood pressure and breathing return to normal.
Alternatives to Penicillin
If you are allergic to penicillin, your doctor will likely skip that medication and give you a different type of antibiotic that is more appropriate for your infection. In very rare cases, when penicillin is the only option, a procedure called desensitization is used. This involves gradually increasing the dose under medical supervision, starting with a very small dose, to help your body get used to the penicillin. This is only done when absolutely necessary.💡 Take-Home Message
