Penicillin is an antibiotic that has been used for the past 70 years or so to treat different kinds of illnesses and infections. It comes from the mold penicillin notatum, which is a blue-green kind of mold sometimes found growing on food.

Before the invention of this drug, infections and diseases that are only minor to us could very well be fatal. Because it is made from mold and reproduces quickly, it's not very difficult to manufacture at all and therefore it is the most popular antibiotic in use worldwide today.

If you are allergic to penicillin or know someone who is, you might know a bit about what to expect if your new baby is allergic. If not, you should know that an allergic reaction to penicillin, especially at such a young age, can be fatal.

These reactions can be anything from a simple skin rash all the way to breathing difficulties that can be life-threatening. If you go to a doctor regularly, you should have had to answer a question on a form that asked if you were allergic to penicillin.

This is so they know whether or not they can administer the drug if you are admitted to the hospital because it is the most frequently occurring drug allergy in existence today.

Even though penicillin is a drug made from mold designed to help us fight infections, you can be allergic to it like any other mold. The medical industry is unsure why some people have reactions to penicillin and some do not, but knowing if you are allergic is very important.

Some only have minor symptoms when exposed to the drug and some can be put near death by it. The only treatment for being allergic to the drug is simply not to use it. There are other antibiotics that can be used to fight infections besides penicillin.

The symptoms of a penicillin allergy include swollen lips, tongue, and face or sometimes rashes or hives that can cover a large area of the body. The most life-threatening reaction to the drug is when the bronchial airway becomes extremely swollen and it causes difficulty breathing.

This can be followed by a drop in your blood pressure and will cause lightheadedness. This kind of reaction can be fatal and if you experience any of these symptoms after receiving a dose of penicillin, you should tell your doctor as soon as you can.

If you are allergic, it's possible that your newborn will be allergic as well, so your child's doctor needs to know this before giving them a dose of the drug.
