Penicillin is perhaps the most well-known member of a group of antibiotics called beta-lactams, which refers to a particular structure in their chemical makeup. The structure is also shared by semi-synthetic Penicillins and cephalosporins are also the most common causes of drug allergy. About 10 percent of Americans report having an allergy to penicillin or a related antibiotic. While penicillin allergy most commonly occurs in young adults, reactions can occur at any age. Approximately 300 deaths can be attributed to penicillin allergy each year in the United States. Symptoms of an allergic reaction to penicillin may include anaphylaxis, hives, below-the-skin swelling, asthma symptoms, as well as non-allergic symptoms such as serum sickness, certain forms of anemia, and other drug rashes. While many people report having an allergy to penicillin, less than 10 percent of these actually have a true allergy to the drug. Some patients that have been labeled as "penicillin allergic" may in fact have experienced non-allergic reactions or side effects to the agent, such as gastrointestinal upset, headache, or nausea, and mistaken it for a true allergy. Amoxicillin and penicillin are two of many antibiotics on the market today. They’re actually in the same family of antibiotics, called the penicillin family. This family contains antibiotics that come from a fungus called Other examples include the antibiotics ampicillin and nafcillin. Drugs in this family work in similar ways to treat infections, but there are small differences in the kinds of bacteria each drug fights and the side effects each drug causes. So while amoxicillin and penicillin are different, they’re similar in many ways. As antibiotics, both can be used to treat infections caused by bacteria. They work by stopping the bacteria from multiplying.
Penicillin allergy is an abnormal reaction of your immune system to the antibiotic drug penicillin. Penicillin is prescribed for treating various bacterial infections. Common signs and symptoms of penicillin allergy include hives, rash and itching. Severe reactions include anaphylaxis, a life-threatening condition that affects multiple body systems. Research has shown that penicillin allergies may be over-reported — a problem that can result in the use of less-appropriate and more-expensive antibiotic treatments. Therefore, an accurate diagnosis is needed when penicillin allergy is suspected to ensure the best treatment options in the future. Other antibiotics, particularly those with chemical properties similar to penicillin, also can result in allergic reactions. Antibiotics and alcohol can cause similar side effects, such as stomach upset, dizziness and drowsiness. Combining antibiotics and alcohol can increase these side effects. A few antibiotics — such as metronidazole (Flagyl), tinidazole (Tindamax), and sulfamethoxazole and trimethoprim (Bactrim) — should not be mixed with alcohol because this may result in a more severe reaction. Drinking any amount of alcohol with these medications can result in side effects such as flushing, headache, nausea and vomiting, and rapid heart rate. Also, the antibiotic linezolid (Zyvox) interacts with certain alcoholic beverages, including red wine and tap beer. Drinking these beverages with this medication can cause a dangerous increase in blood pressure. Keep in mind that some cold medicines and mouthwashes also contain alcohol.
Penicillin is a group of antibiotics that are commonly used to treat different types of gram positive and gram negative bacterial infections. In their structure, beta lactam ring is located due to this reason these drugs are also called as beta lactam antibiotics. Amoxicillin is a penicillin antibiotic which treats infection by killing the germs bacteria responsible for the infection. Amoxicillin is sometimes used to get rid of Helicobacter pylori. This is an infection often found in people with stomach ulcers.
