an allergic to penisillin

A penicillin allergy is an allergic reaction that occurs when your body’s immune system overreacts to this particular antibiotic. Commen allergy reactions to penicillin include:

- Rash
- Hives
- Itchy eyes
- Swollen lips, tongue or face

In rare cases, an allergy to penicillin can cause a severe or anaphylactic reaction, which can be life-threatening. This type of reaction usually develops within an hour after you take penicillin. Symptoms include:

- Difficulty breathing
- Hives
- Wheezing
- Dizziness
- Loss of consciousness
- Rapid or weak pulse
- Skin turning blue
- Diarrhoea
- Nausea
- Vomiting

If you think you are experiencing anaphylactic reaction, you must seek medical help immediately. Penicillin belongs to a group of antibiotics called beta lactams, which refers to a particular structure in their medical makeup. The structure is also shared by semi-synthetic penicillin (amoxicillin), cephalosporin and other antibiotics like imipenem. Some people who are allergic to penicillin are also allergic to other closely related antibiotics, including cephalosporin. Be sure to tell your doctor and other medical professionals, including your dentist, of your allergy to penicillin. Your doctor or dentist will the prescribe an antibiotic totally unrelated to penicillin.
