Generic Amoxil (Amoxicillin)
Amoxil (active component – Amoxicillin) is a wide-spectrum antibiotic of the penicillin family, used for treatment of different types of infections caused by bacteria. This medicine has the strong bactericidal effect, which is produced by suppressing the bacterial cell walls.
Amoxicillin was developed by Beecham in 1972 and was marketed by GlaxoSmithKline (the successor of Beecham) under the trade name of Amoxil, and has not lost its popularity over the years. It is largely due to the fact that the field of its application is surprisingly wide, as it produces a high bactericidal effect on both gram-positive and gram-negative aerobic and anaerobic flora. Therefore, this drug can be taken as a monotherapy even in those cases when it would be necessary to use therapy with a combination of two or more antibiotics.
Amoxil is usually prescribed to the patients suffering from:
- upper and lower respiratory tract infections (tonsillitis, sinusitis, otitis media, exacerbation of chronic bronchitis, pneumonia),
- urinary tract infections (cystitis, urethritis, pyelonephritis, sexually transmitted infections, gynecological and obstetrical infections);
- skin and soft tissue infections (erysipelas, impetigo, dermatosis) , spinal infections (osteomyelitis);
- may be used as perioperative prevention of surgical infection.
Please note that the drug will not treat a viral infection, for example, a common cold or flu. Do not give it to another person, even if it seems that they have the same symptoms with you.
Before taking amoxicillin 500mg, please talk to your individual physician. It is better to refrain from taking it in some cases:
- if you have allergy to amoxicillin or any other antibiotic of the penicillin group;
- if you suffer from infectious mononucleosis.
- if you have bleeding or blood clotting disorders;

With the simultaneous use of amoxicillin and oral contraceptives, the effectiveness of the latter decreases, and there is a possibility of bleeding. Amoxicillin increases the absorption of digoxin, reduces clearance and increases the toxicity of methotrexate. Excretion of amoxicillin from the body by the kidneys slows down with simultaneous application with probenecid, oxyphenbutazone, phenylbutazone, acetylsalicylic acid, indomethacin, sulphinperazone. Preparations that have a bacteriostatic effect (tetracyclines, macrolides, chloramphenicol) can neutralize the bactericidal effect of amoxicillin.
Forced diuresis leads to a decrease in the concentration of amoxicillin in the blood. Simultaneous application with allopurinol, can lead to increase of the frequency of allergic reactions from the skin.
Simultaneous reception with antacids reduces the absorption of amoxicillin. When used simultaneously with anticoagulants, it is necessary to control prothrombin time, as the probability of bleeding increases.
The appearance of diarrhea can reduce the absorption of other drugs and reduce the effectiveness of the drug.
It can reduce the concentration of estradiol in the urine of pregnant women.
Capsules, chewable tablets, and oral suspensions may be given without regard to meals. The 400-mg suspension, 400-mg chewable tablet, and the 875-mg tablet have been studied only when administered at the start of a light meal.

The night before yesterday I couldn’t fall asleep because of urethritis. In the morning I came to the doctor who prescribed me Amoxil, which I did not use before. By the way, this unpleasant disease happened to me for the first time. I read on the Internet about this drug, everyone tells that it is good to treat urethritis and cystitis.
I did not really want to take it, it's still an antibiotic, but the nasty manifestations of urethritis were exhausting. I took a pill and one third of a glass of water, drank it on an empty stomach, before going to bed. But I was not yet sure that I could sleep, that everything would pass. But… it's gone: the bacteria in the pee-hole was killed immediately, I suppose. It is now much easier for me.
Now everything is normal, although it would be necessary to reinforce the result with the urological stuff. So, I can say this medicine is really very good for urethritis. I noticed no side effects.
An excellent drug. It always helps me against angina. At the first signs of the disease, I prescribe it to myself, and use it, as written in the instructions, along with calcium gluconate tablets and warming up procedures (footbaths, applications, etc). I do not trust every new medicine. They only relieve symptoms, but do not treat the disease itself. The drug is quite affordable and reliable medicine. And because it is so cheap I'm not afraid of fakes.
My 4-year-old nephew, the son of my younger sister, is very energetic and interested in everything. So, what gets into his hands gets in his mouth also, you are not always able to follow him. I think that because of this, he was determined to catch an enteric infection. I advised my sister to give my nephew Amoxil, because I always took this pills when have any infection, and they always helped me. After 4 days of treatment, the nephew was OK. There were no allergy or any other side effects never ever.
For the first time I used these tablets about fifteen years ago, when my oldest daughter was small, and the doctor prescribed it for pneumonia. The drug always helped us, the whole family. Now my younger child had pneumonia, and was prescribed some new expensive antibiotics, but… I must confess… I gave her an old proven Amoxil. It still works well, does not provoke any allergies, and the side effects described in the annotation have never been observed. I always follow the instructions, and, as a rule, after 7 days of taking the baby is healthy. In my opinion, here the following principle works: “cheap” does not mean “bad.” I’m absolutely satisfied with its price and effectiveness.
