When Are Antibiotics Usually Prescribed
Antibiotics are normally only prescribed for more serious infections with germs .
Most common infections are caused by viruses, when an antibiotic will not be of use. Even if you have a mild bacterial infection, the immune system can clear most bacterial infections. For example, antibiotics usually do little to speed up recovery from most ear, nose and throat infections that are caused by bacteria.
So, do not be surprised if a doctor does not recommend an antibiotic for conditions caused by viruses or non-bacterial infections, or even for a mild bacterial infection.
However, you do need antibiotics if you have certain serious infections caused by bacteria, such as meningitis or pneumonia. In these situations, antibiotics are often life-saving. When you are ill, doctors are skilled at checking you over to rule out serious illness and to advise if an antibiotic is needed. Urine infections also commonly need antibiotics to prevent spread to the kidneys.
Antibiotics can also be prescribed to treat acne – a less serious condition. For acne, antibiotics can be taken by mouth or applied directly to the skin.
Chasing Antibiotics With Good Bacteria Could Prevent Bad Infections
Your body is home to trillions of bacteria but before you go reaching for the soap, its important to remember that many of them are good for you. Not only do they assist in vital bodily functions, but they can help keep bad bugs at bay. Now, researchers at Instituto Gulbenkian de Ciência in Portugal and Stanford in the US have identified one particular bacterium, Klebsiella michiganensis, that could be administered to help prevent harmful infections.
Antibiotics are currently our best defense against pathogenic infections, but the problem is they arent very selective. Taking antibiotics is akin to carpet-bombing your insides, killing good and bad bacteria alike. So, while the drugs may kill off whatever infection was troubling you, they also take out good bugs and leave the door open for opportunistic pathogens, like E. coli and Salmonella, to recolonize in unhealthy amounts.
In the new study, researchers at IGC and Stanford isolated one particular bacteria species that seems to protect against these pests. K. michiganensis is often present in the gut in relatively low numbers, but its better at metabolizing certain nutrients than E. coli, Salmonella and other bad bugs, meaning they struggle to get a foothold.
This study opens doors to the hope that for each human pathogen there is one or more bacteria of the microbiota that can be administered as a direct competitor of that pathogen, says Rita Oliveira.
How To Take Amoxicillin
Instructions for how to take amoxicillin are different depending on the condition being treated. Amoxicillin is typically prescribed in its generic form, but its available in the following brand names in the United States: Amoxil, Larotid and Moxatag.

Medications For Bacterial Vaginosis
Bacterial vaginosis is a bacterial infection in the vagina. It is the most common cause of abnormal vaginal odor and discharge in young women and is caused by a change in the balance and type of bacteria which are normally present in the vagina.
Although BV is not considered a sexually transmitted disease, the risk of developing BV seems to increase the more sexual partners a woman has.
Normally, Lactobacillus bacteria are the most common type of bacteria within the vagina. These produce chemicals that keep the vagina mildly acidic. In BV, numbers other types of bacteria within the vagina that are usually only present in small numbers increase and disrupt both the pH of the vagina and its lining. This can result in BV, and symptoms may include:
- Mild itching in and around the vagina
- Bad-smelling, fishy odor that is more noticeable during menstruation or after sex)
- Pain when urinating.
Some women with BV have no symptoms, which is a bit concerning because if BV isnt treated it can increase the chance of women developing STDs , pelvic inflammatory disease, and possibly increase the risk of miscarriage. In women who are pregnant, BV can result in premature labor and delivery, premature rupture of membranes, and postpartum uterine infections.

Most side-effects of antibiotics are not serious. Common side-effects include soft stools , diarrhoea, or mild stomach upset such as feeling sick . Less commonly, some people have an allergic reaction to an antibiotic and some have died from a severe allergic reaction – this is very rare.
Antibiotics can kill off normal defence bacteria which live in the bowel and vagina. This may then allow thrush or other bad bacteria to grow.
You should tell your doctor if you have any of the following side-effects:
- Severe watery diarrhoea and tummy cramps: signs of a serious bacterial infection of the gut – Clostridium difficile infection.
- Shortness of breath, hives, rash, swelling , fainting: signs of an allergic reaction.
- White patches on the tongue: signs of oral thrush.

When To Use Antibiotics For A Tooth Infection
Generally, your dentist will only prescribe antibiotics in dentistry for dental infections. Acute infections resolve on their own. Nevertheless, not all infected teeth need antibiotics. Sometimes, a dentist might simply drain the infected part, eliminate the infected tooth, or do a root canal treatment to solve the issue. In fact, dentists tend to avoid using antibiotics except if they are essential. This is particularly true when the infection is severe or spreading or if the patient has a weakened immune system. In addition, the sort of antibiotic you will require relies upon the type of bacteria causing the infection. Your dentist will choose an antibiotic that can effectively eliminate your condition.

Names Of Common Antibiotics
Antibiotics are a common, important group of medicines that treat bacterial infections. Some antibiotics attack or break down the cell walls of bacteria, while others inhibit their protein production. This kills the bacteria or keeps it from reproducing and spreading.

Healthcare professionals prescribe different antibiotics to treat conditions such as strep throat, bronchitis, and inner ear infections. In this case, these infections are moderate to severe and have not improved with other treatments. Antibiotics do not treat viral illnesses, such as a cold, the flu, or mono.
These drugs are grouped according to their antibacterial activity and chemical structure. Specific antibiotics fight certain bacteria, which makes it important to take the right kind. A healthcare professional may ask for a lab culture test to determine which antibiotics you need.
