Maxibiotic 500 is a brand of Cephalexin, an antibiotic that belongs to the family of medications known as cephalosporins. Maxibiotic 500 is used to treat certain types of bacterial infections. Cephalexin is most often used to treat infections of the throat, skin, ear, bladder, respiratory tract, and bone. It works by killing the bacteria causing the infection.
How should I use Maxibiotic 500?
The recommended adult dose of cephalexin ranges from 250 mg to 1,000 mg 4 times daily. It can be taken with food or on an empty stomach.
The usual dose of cephalexin for children is based on body weight. The recommended dose is 25 mg to 50 mg per kilogram of body weight each day, divided into 4 equal doses.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Although it may be absorbed more quickly if it is taken on an empty stomach, Maxibiotic 500 may be taken with food or on an empty stomach. The overall effect is not changed by taking it with food.
The liquid form of this medication should be measured accurately with a medication spoon or oral syringe, as these are more accurate than household measuring spoons. Shake the bottle of medication well before measuring each dose.
Finish all of this medication, even if you start to feel better. This will reduce the chance of the infection returning.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergy: Some people who are allergic to penicillin antibiotics also experience allergic reactions to cephalosporins, including Maxibiotic 500. Before you take Maxibiotic 500, tell your doctor about any previous adverse reactions you have had to medications, especially cephalosporins and penicillins. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing, or swelling of the face and throat.
Other hypersensitivity reactions involving the skin and other organs have also been reported with the use of other, similar antibiotics. Stop taking the medication and get immediate medical attention if you have symptoms of a severe allergic reaction, including fever, swollen glands, yellowing of the skin or eyes, or flu-like symptoms with skin rash or blistering.
Antibiotic-associated colitis: This medication, like other antibiotics, may cause a potentially dangerous condition called antibiotic-associated colitis (or pseudomembranous colitis). Symptoms include severe, watery diarrhea that may be bloody. If you notice these symptoms, stop taking Maxibiotic 500 and contact your doctor as soon as possible.
Bacterial resistance: Misuse of an antibiotic such as Maxibiotic 500 may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking Maxibiotic 500, you need to take all of the medication exactly as prescribed by your doctor to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take Maxibiotic 500 or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Kidney function: People with severe kidney problems may require a lower dose of Maxibiotic 500. People with kidney disease or reduced kidney function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Maxibiotic 500 can cause a decrease in liver function, although this happens only occasionally. People with liver disease or reduced liver function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience signs of decreasing liver function, such as yellowing of the skin or whites of the eyes, dark urine, or pale stools, contact your doctor as soon as possible.
Overgrowth of organisms: Prolonged or repeated use of Maxibiotic 500 may result in an overgrowth of bacteria or fungi and organisms that are not killed by the medication. This can cause other infections to develop, such as yeast infections.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking Maxibiotic 500, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
