Bacterial drug resistance,
Pseudomembranous enteritis,
These two phenomena are relatively common.
Side effects of cephalosporins?
Myth 1: Antibiotics are cold medicines: Many people use antibiotics to treat colds or think that antibiotics can reduce fever. In fact, although antibiotics can resist bacteria and some microorganisms, they are not antiviral. Most colds are viral infections. If antibiotics are used indiscriminately, it will only increase its side effects and make the body resistant to drugs. In addition, patients with bacterial infection will be accompanied by fever, making
Antibiotics are used to make inflammation subside and body temperature naturally return to normal. However, not all fevers are caused by bacterial infection. The common cold is caused by virus and fever, and antibiotics don't work.
Myth 2: The new generation is better than the previous generation: Many people think that the third and fourth generations of cephalosporins are new and expensive, and the curative effect is definitely better than the first and second generations. Clinical practice has proved that the antibacterial effect of the first generation cephalosporins with low price on staphylococcus is better than that of the third and fourth generations cephalosporins. Doctors believe that newer and more expensive antibiotics have better efficacy. What matters is what bacteria caused the patient's infection and where the infection occurred. Doctors should choose varieties with strong effect on pathogenic bacteria and high drug concentration in infected parts according to the condition to achieve the best curative effect.
Several commonly used antibiotics
Penicillin antibiotics: also known as β -lactam antibiotics. General commodity name: amoxicillin. Efficacy: Broad-spectrum antibiotics, targeting most positive bacteria, act on skin mucosa, soft tissue and urinary system infections.
Macrolide antibiotics: common trade name: roxithromycin. Efficacy: Antibacterial agent, mainly used for upper respiratory tract infection.
Quinolone antibiotics: one is norfloxacin, the common trade name is norfloxacin; One is levofloxacin tablets, and the common trade name is Lifosun. Efficacy: used for upper respiratory tract and gastrointestinal tract infections. It has obvious effect on urinary system infection.
Azithromycin antibiotics: a new generation of macrolide antibiotics. Commodity name: Tellite. Efficacy: broad-spectrum antibiotics, used for respiratory tract, skin, soft tissue, facial features, genital infections, etc.
Manifestations of abuse of antibacterial drugs
1, improper use of Dan
2. Don't choose drugs with the best curative effect, the least toxic and side effects and moderate price (abuse of broad-spectrum, new and expensive drugs);
3, unprincipled combination medication;
4, regardless of individual differences (age, liver and kidney function, pregnancy, breastfeeding, immune function, etc. ).
Harm of abuse of antibacterial drugs
1, poor curative effect;
2. Adverse reactions increased;
3. The growth of bacterial drug resistance;
4. Medical expenses have increased in disorder.
How to use antibiotics reasonably
1, whether the patient must use antibacterial drugs;
2. Determine the types of bacteria causing infection as soon as possible;
3, according to the most likely pathogenic bacteria using empirical treatment.
Pay attention to medication for the elderly
1. Choose fungicides with low toxicity: penicillins and cephalosporins;
2, the dose should be low, adjusted according to the degree of renal insufficiency, generally 2/3-3/4 of that of adults;
3. Drugs with obvious toxicity need individualized administration;
4, many adverse reactions, but easy to ignore, need to be closely observed;
5. Pay attention to comprehensive treatment.
Pay attention to the medication of children's infection.
1. Safe and effective fungicides should be selected: penicillins, cephalosporins, etc.
2. Calculate the dose according to the weight and age;
3. Avoid using drugs with obvious toxicity: aminoglycosides such as gentamicin, chloramphenicol, norvancomycin, furans, sulfonamides, tetracyclines, etc.
4. Avoid intramuscular injection.
Pay attention to pregnant women's medication
1. Drugs that can be safely selected during pregnancy: penicillins, cephalosporins, macrolides (except esters), fosfomycin, etc.
2. Drugs to be avoided during pregnancy: tetracycline, erythromycin ester, aminoglycosides, quinolones, sulfonamides and furans.
