Amoxicillin

Amoxicillin is a penicillin antibiotic. It fights bacteria in your body. Amoxicillin is used to treat many different types of infections caused by bacteria, such as ear infections, bladder infections, pneumonia, gonorrhea, and E. coli or salmonella infection. Amoxicillin is also sometimes used together with another antibiotic called clarithromycin (Biaxin) to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer called lansoprazole (Prevacid). Amoxicillin may also be used for purposes not listed in this medication guide. Important information about amoxicillin

Do not use this medication if you are allergic to amoxicillin or to any other penicillin antibiotic, such as ampicillin (Omnipen, Principen), dicloxacillin (Dycill, Dynapen), oxacillin (Bactocill), penicillin (Beepen-VK, Ledercillin VK, Pen-V, Pen-Vee K, Pfizerpen, V-Cillin K, Veetids), and others. Before using amoxicillin, tell your doctor if you are allergic to cephalosporins such as Omnicef, Cefzil, Ceftin, 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. Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop taking amoxicillin and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to. Amoxicillin side effects

Get emergency medical help if you have any of these signs of an allergic reaction to amoxicillin: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Call your doctor at once if you have a serious side effect such as: * white patches or sores inside your mouth or on your lips; * fever, swollen glands, rash or itching, joint pain, or general ill feeling; * severe blistering, peeling, and red skin rash;

* pale or yellowed skin, yellowing of the eyes, dark colored urine, fever, confusion or weakness; * severe tingling, numbness, pain, muscle weakness; or
* easy bruising, unusual bleeding (nose, mouth, vagina, or rectum), purple or red pinpoint spots under your skin. Less serious amoxicillin side effects may include:
* stomach pain, nausea, vomiting;
* vaginal itching or discharge;
* headache; or
* swollen, black, or "hairy" tongue.

COTRIMOXAZOLE

Pharmacology
Sulfamethoxazole inhibits bacterial synthesis of dihydrofolic acid by competing with PABA. Trimethoprim blocks production of tetrahydrofolic acid by inhibiting the enzyme dihydrofolate reductase. This combination blocks 2 consecutive steps in bacterial biosynthesis of essential nucleic acids and proteins and is usually bactericidal.

Cefalexin

What is cephalexin (cefalexin)?
Cephalexin (cefalexin) is a cephalosporin antibiotic used to treat bacterial infections of the upper respiratory tract, the middle ear, the bones, the skin, and the reproductive and urinary systems. Cephalexin (cefalexin) works by interfering with the bacteria's cell wall formation. This weakens the cell wall, causing it to rupture, and kills the bacteria. As cephalexin (cefalexin)is only effective against certain types of bacterial infection your doctor may perform tests to identify the organisms causing the infection before beginning treatment . Cephalexin (cefalexin) may also be used for other purposes not listed here. Cephalexin (cefalexin) is available in capsule, tablet, and liquid forms. It is usually taken every 6 hours (four times a day) or every 12 hours (twice a day) for 7-10 days. Important information about cephalexin

Do not use this medication if you are allergic to cephalexin, or to similar antibiotics, such as Ceclor, Ceftin, Cefzil, Duricef, Fortaz, Omnicef, Spectracef, Suprax, and others. Before using cephalexin, tell your doctor if you are allergic to any drugs (especially penicillins), or if you have kidney or liver...
