Common uses:

This medication is used to treat many different types of infections, such as pneumonia, bronchitis, venereal disease (VD), gonorrhea, and infections of the ears, nose, throat, urinary tract, and skin. It is also used before some surgery or dental work to prevent infection and used in combination with other medicines to treat patients with H. pylori infections.

Before using

Do not use this medication if you are allergic to Amoxil or to any other penicillin antibiotic, such as ampicillin (Omnipen, Principen), carbenicillin (Geocillin), dicloxacillin (Dycill, Dynapen), oxacillin (Bactocill), penicillin (Beepen-VK, Ledercillin VK, Pen-V, Pen-Vee K, Pfizerpen, V-Cillin K, Veetids), and others.
Before using Amoxil, tell your doctor if you are allergic to cephalosporins such as Ceclor, Ceftin, Duricef, Keflex, and others. Also tell your doctor if you have asthma, liver or kidney disease, a bleeding or blood clotting disorder, mononucleosis (also called "mono"), or any type of allergy.
Amoxil can make birth control pills less effective, which may result in pregnancy. Before taking Amoxil, tell your doctor if you use birth control pills. Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Amoxil will not treat a viral infection such as the common cold or flu. Do not give this medication to another person, even if they have the same symptoms you do.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.


Directions

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
If you are taking amoxicillin with clarithromycin and/or lansoprazole to treat stomach ulcer, use all of your medications as directed. Be sure to read the medication guide or patient instructions provided with each of your medications. Do not change your doses or medication schedule without advice from your doctor.
You may take amoxicillin with or without food.
Shake the oral suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
You may place the liquid directly on the tongue, or you may mix it with water, milk, baby formula, fruit juice, or ginger ale. Drink all of the mixture right away. Do not save any for later use.
The chewable tablet should be chewed before you swallow it.
The dispersible tablet will not dissolve in your mouth. Place the tablet in at least 2 teaspoons of water (do not use any other type of liquid). After the tablet has completely broken apart, swirl the mixture and drink all of it right away.
To be sure this medication is helping your condition, your blood may need to be tested. Your kidney or liver function may also need to be tested. Do not miss any scheduled visits to your doctor.
If you are being treated for gonorrhea, your doctor may also have you tested for syphilis, another sexually transmitted disease.
Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.

This medication can cause you to have unusual results with certain medical tests. Tell any doctor who treats you that you are using amoxicillin.
