What is amoxicillin
Amoxicillin is an antibiotic of the penicillin family. It has become one of the most used options in this group because of its effective action, The convenience of being able to take it two or three times a day, and, above all, because it does not require piercing, it is simply taken by mouth.
This semi-synthetic antibiotic has an effect on different types of bacteria: Gram-negative, Gram-positive and other species such as Proteus, Salmonella and Shigella.
What infections does amoxicillin treat?
Amoxicillin is useful for a variety of bacterial infections, such as those found in :
- Upper respiratory tract (nose, throat and ear): Not all problems of throat congestion are resolved with this antibiotic. In fact, the vast majority of pharyngitis (about 90%) is caused by viruses, so its indications must be precise, but it can be prescribed by a professional in certain cases of pharyngitis, otitis media, rhinosinusitis.
- It can also be used in the mouth before a dental extraction.
- Lower respiratory tract (bronchial tubes and lungs): Useful in the treatment of acute and chronic bronchitis, as well as some cases of bacterial pneumonia.
- Skin and soft tissues.
- Genitourinary and urinary system.
- Gastrointestinal tract: in cases of peptic ulcer and bile duct infections.
How long does it take amoxicillin to work on a toothache
When used correctly, which is in infections caused by bacteria sensitive to the antibiotic, it takes about 24-48 hours for amoxicillin to start working.
The most common ones in these cases are:
- Bringing down the fever.
- Soothes toothache
- Gradually the inflammation decreases.
- The pain also decreases.
Obviously, it also depends on several factors such as: your immune system status, the complexity of the infection, and other illnesses you have, as well as whether or not you have ever used antibiotics, etc.
As we mentioned above, amoxicillin is a widely used antibiotic, sometimes properly and sometimes not. That’s why it sometimes takes longer than usual for it to work, because it wasn’t the right treatment. This usually occurs in the following cases:
- Viral infection
- Bacterial infections caused by microorganisms that are insensitive to amoxicillin.
- Inappropriate use of this antibiotic on previous occasions.
- Weak defenses.
- The infection is caused by several different microorganisms.
For amoxicillin treatment to be effective, the way you take it is very important.
How often do you take amoxicillin?
It depends on the dose and the medical problem you need to take it for. In general, for mild infections, it is indicated every 8 hours. Some cases may be given every 12 hours.
How many days do you take amoxicillin?
In general, for mild infections, 7 days of treatment is usually indicated. Sometimes it may take 14 or 21 days or more, depending on the disease to be treated or prevented and the health of the person being treated.
Medications that may change the effect of amoxicillin
This is an important point to note. Some medications can change the way amoxicillin is absorbed or works in your body. Thus we have the following cases:
- Other antibiotics can reduce the bactericidal action of amoxicillin: tetracyclines, chloramphenicol, macrolides.
- Some medications can increase the circulation of amoxicillin in the blood, making it last longer in the body. These include acetylsalicylic acid (aspirin), probenecid, indomethacin and phenylbutazone.
- Amoxicillin may reduce the effect of oral contraceptives.
- Side effects may increase if amoxicillin is used with methotrexate and allopurinol.
- Some drugs inhibit bactericidal effect: tetracyclines, chloramphenicol, and macrolides
Reasons not to take amoxicillin if not prescribed by a doctor
It is very important to use this medicine when it is really needed. If you take amoxicillin unnecessarily, not only will your health problem be solved, but It will also be less likely to be effective when you really need it.
This is due to a phenomenon called bacterial resistance. When you take an antibiotic at the wrong time, you make the bacteria stronger or more resistant over time, which means that amoxicillin will have no effect on them. This is true for this and all antibiotics.
On the other hand, you are overloading your body with chemicals that need to be processed and eliminated, making it difficult to manage the health problem for which you took the antibiotic.
