Penicillin - Uses, Side Effects & Allergy Warnings

Introduction

What is penicillin?

A class of antibiotics known as penicillin is generated from the mould Penicillium. They work well against a variety of bacteria, including Neisseria, Streptococcus, and Staphylococcus.

Penicillin is a useful tool to the fight against bacterial infections. They are effective, safe and relatively inexpensive.

How does penicillin work?

A class of antibiotics known as penicillin works by preventing the synthesis of the bacterial cell wall. The bacterial cell wall is a rigid structure that protects the bacteria from the environment.

Penicillin binds to a specific enzyme that is essential for cell wall synthesis, called transpeptidase. This binding prevents the enzyme from working, which prevents the bacteria from building a new cell wall. As a result, the bacteria eventually burst and die.

What are the different types of penicillin?

Here are the different types of penicillin:

Natural penicillin

Natural penicillin is the original penicillin that was discovered in the 1940s. They are very much effective against a wide range of gram-positive bacteria, but they are not effective against gram-negative bacteria. Examples of natural penicillin include penicillin G and penicillin V.

Penicillinase-resistant penicillin

Penicillinase-resistant penicillin is effective against gram-positive bacteria that produces an enzyme called penicillinase, which breaks down penicillin. Examples of penicillinase-resistant penicillin include methicillin, oxacillin, nafcillin and cloxacillin.

Aminopenicillin

Aminopenicillin is more effective against gram-negative bacteria than natural penicillin. They are also effective against some gram-positive bacteria. Examples of aminopenicillin include ampicillin, amoxicillin and hetacillin.

Extended-spectrum penicillin

Extended-spectrum penicillin are effective against a wider range of gram-negative bacteria than aminopenicillin. They are also effective against some gram-positive bacteria. Examples of extended-spectrum penicillin include carbenicillin, ticarcillin, and piperacillin.

Beta-lactamase

Beta-lactamase inhibitors are drugs that prevent bacteria from producing the enzyme penicillinase. They are often used in combination with penicillin to make them more effective. Examples of beta-lactamase inhibitors include clavulanic acid and sulbactam.

Uses of penicillin

There are several different bacterial illnesses that penicillin is used to treat, such as:

Ear infections: Penicillin is often used to treat ear infections caused by Streptococcus pneumoniae or Haemophilus influenzae.

Sinus infections: Penicillin is often used to treat sinus infections caused by Streptococcus pneumoniae, Haemophilus influenzae or Moraxella catarrhalis.

Pneumonia: Penicillin is often used to treat pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae or Mycoplasma pneumoniae.

Lyme disease: Lyme disease, which is brought on by Borrelia burgdorferi, is typically treated with penicillin.

Gonorrhea: Penicillin is the first-line treatment for gonorrhea, which is caused by Neisseria gonorrhoeae.

Syphilis: Penicillin is the first-line treatment for syphilis, which is caused by Treponema pallidum.

Side effects of penicillin

Here are some more details about the side effects of penicillin:

Mild side effects

Nausea

One of the most adverse reactions to penicillin is nausea. It normally subsides on its own and is minor. You could try taking the medication with food or liquid if you feel uneasy.

Vomiting

Vomiting is another common side effect of penicillin. If you experience vomiting, you may try taking the medication with food or drink.

Diarrhoea

If you experience diarrhoea, you may try taking the medication with food or drink.

Headache

Headache is a less common side effect of penicillin. If you experience headache, you may try taking over-the-counter pain medication.

Serious side effects

Allergic reactions are a serious side effect of penicillin. They can occur in people who have been allergic to penicillin in the past. Allergic reactions can be life-threatening.

• Hives
• Wheezing
• Chest pain
• Dizziness
• Fainting

It is always recommended to check with your doctor before taking any medications.

Symptoms of a penicillin allergy can include:

Here are some more details about the symptoms of an allergic reaction to penicillin:

Hives

Hives are raised and itchy bumps on the skin. They can be red, white, or skin-colored. Hives can be small or large, and they can come and go.

Rash

Rash is a general term for any skin eruption. Numerous factors, including infections, drugs and allergic responses, might contribute to it.

Swelling

Swelling of the tongue, lips or throat is a serious allergic reaction that can block your airway and make it difficult to breathe. If you experience this, you should seek medical attention immediately.

If you experience any of these symptoms after taking penicillin, you should stop taking the medication and seek medical attention immediately. An allergic reaction to penicillin can be life-threatening.

Conclusion

To sum up. Penicillin is a reliable and efficient treatment for a wide range of bacterial infections. Before using penicillin, you should be aware of any possible side effects and allergy precautions.
