Nowadays, many young people have an open sex life, and one-night stands and dating are commonplace. The biggest risk of having sex with a stranger is to be infected with STDs, and some people are smart enough to think of some “tips” to prevent STDs, and eating some antibiotics before having sex can improve the resistance, is one of them. Is this really reliable? Antibiotics, mainly used to treat various bacterial infections or pathogenic microbial infections, are not effective for diseases caused by viruses and other simple structured pathogens. So like genital herpes, condyloma, AIDS and other such diseases caused by viral infections, taking antibiotics is not useful. Among our common sexually transmitted diseases, gonorrhea, non-gonococcal urethritis and syphilis are three types of diseases that are usually treated with antibiotics. The abuse or overuse of antibiotics in the case of uncertainty about whether there is an infection, not only is it easy to cause drug resistance making treatment more and more difficult, long-term use will also make the body flora disorder, causing greater impact on health. The actual fact is that you can find a lot of people who have been in the business for a long time. The longest time these patients take antibiotics is nearly twenty years in a row, so you can imagine that the flora system in her body is seriously disturbed for so many years, and it is not easy to recover. Among the three common sexually transmitted infections, gonorrhea is the most resistant to antibiotics. Recent studies have detected multi-drug resistant strains of gonococcus that do not respond to any of the available antibiotic treatments. Once gonorrhea is diagnosed, it should be treated immediately. Diagnose and treat early, and use the correct medication as prescribed by your doctor. Treatment should follow the principles of timely, adequate and standardized medication, and different treatment plans should be chosen according to the different conditions and gonococcal drug resistance in the region and the patient’s response, as well as the examination or treatment of sexual partners. Follow-up and re-examination are also conducted after treatment to ensure cure and eliminate the source of infection. The choice of treatment options for gonorrhea is influenced by a variety of factors, and treatment options are constantly changing from time to time and from region to region as the rate of infection with drug-resistant strains increases and new drugs are developed. The most commonly used and effective drug for the treatment of gonorrhea is ceftriaxone sodium (Mycobacterium bovis, ceftazidime). A single intramuscular injection is all that is needed after the diagnosis is confirmed. Sexual intercourse should be avoided during the treatment period. Some patients who have gonorrhea think that the more drugs they use the better and the more expensive the better. If it is clear that oral medicine can cure, it must be injected, and if it is clear that one injection can cure, it always requires several more injections, and some even use five or ten injections of medicine. This is not right. Overdosing and overtreatment is not only unhelpful but also harmful. In addition to easily inducing the emergence of drug-resistant strains of bacteria, it also tends to cause the growth of fungi in the urethra or vagina and the occurrence of candida urethritis or vaginitis. Some patients who have gonorrhea often also have a co-infection with chlamydia, resulting in non-gonococcal urethritis. Resistance of chlamydia to antibiotics, although uncommon, exists and prevention and timely treatment is essential. The treatment of chlamydial infection can use tetracyclines such as doxycycline, minocycline; also macrolides such as azithromycin, roxithromycin, clarithromycin, cross-fasteners; also quinolones such as levofloxacin, sparfloxacin, etc.. Generally taking a course of recommended drugs (7 to 10 days), clinical symptoms are relieved. Treatment of syphilis is still strongly recommended with a single dose of benzathine penicillin (an antibiotic administered by a physician or nurse through intramuscular injection in the buttock or thigh). This is the most effective drug for treating syphilis because it is more effective and less expensive than oral antibiotics. Some patients have early syphilis (hard chancre or early syphilis rash) and buy some antibiotics to eat, but the symptoms of syphilis rash disappear after taking the medicine, but the syphilis spirochetes in the body are not all killed, and a small amount of latent turns into latent syphilis, which brings great hidden danger to the body. According to the World Health Organization estimates, each year there are 131 million people infected with chlamydia, 78 million people infected with gonorrhea and 5.6 million people infected with syphilis worldwide. Insisting on the correct use of condoms and avoiding high-risk sex with strangers are the most effective ways to prevent sexually transmitted diseases. Misuse of antibiotics, on the other hand, can cause resistance to bacteria and viruses and cause other harm to the body, in addition to delaying the disease.
