What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
Keflex is a type of antibiotic medication. It works by keeping bacteria from growing and ending a bacterial infection. It’s in a classification known as cephalosporin antibiotics. An antibiotic doesn’t work for treating a virus like a cold or influenza. It shouldn’t be taken for any type of infection that isn’t bacterial in nature.
The generic name for it is cephalexin. This antibiotic is commonly used for patients who need to take an antibiotic before a dental procedure because of a specific heart condition. This can help them to avoid coming down with a bacterial infection of the heart. These are also known as endocarditis. This drug is also used for common bacterial infections that are already present.

Precautions and Warnings of Keflex
There are a lot of people who have allergic reactions to this medication, and that’s especially true in those who have a penicillin allergy. About 10% of patients with an allergy to penicillin will also be allergic to Keflex. The types of allergic reactions can include a rash, toxic epidermal necrolysis, anaphylaxis, Stevens-Johnson syndrome, and others. It’s important to pay attention to anything that changes after you’ve taken this antibiotic. If you have a serious allergic reaction, seek immediate medical care.
It’s also possible to have a condition called Clostridium difficile-associated diarrhea, better known as CDAD. Keflex has been found to be a cause just like virtually all antibiotics. When Keflex is used to treat a bacterial infection, it can allow the C. difficile in the colon to get overgrown. It can then produce toxins that can be highly damaging to the patient’s health. This is what causes CDAD in some patients. This can be mild, moderate, or extremely severe. It can lead to surgery for some patients and can be fatal. This condition can set in two months after stopping the Keflex or longer.
This medication also causes hemolytic anemia in some patients. If this develops, the Keflex should be stopped. There is also a potential for seizures from this medication, though this is rare. It happens most often in patients who have renal impairment. If it causes seizures, it should be discontinued. Anticonvulsant medication can be helpful in these cases.
Another possibility with Keflex is getting a drug-resistant bacterial infection. When this medication is taken when there isn’t necessarily a bacterial infection present, it gives patients a higher risk of developing an overgrowth of drug-resistant bacteria. This happens when there’s no infection for the antibiotic to kill, so it starts to kill off the necessary bacteria in the body and starts to ramp up the growth of bacteria that are resistant to it.
Keflex Side Effects
There are many side effects possible from this antibiotic. Many people don’t have any side effects from it while others have side effects that can range from mild to severe.
If the medication is used many times or for a long period of time, it can also cause a yeast infection or oral thrush. If you have severe diarrhea, cramping, or have mucus or blood in your stool, tell your doctor right away. These types of side effects shouldn’t be treated with an opioid medication or with an anti-diarrheal.
If you have the symptoms of an allergy to this medication, you may experience swelling of your face, throat, lips, or tongue. If you find that you’re allergic to this medication, tell the doctor as soon as possible.

Keflex Drug Interactions
There are several interactions that can occur when taking Keflex, and there are also changes to certain tests that can happen. When a patient who is taking Keflex is given a urine glucose test or a Coombs’ test, the results may be altered by the medication. When you have lab tests done, make sure that the medical professionals know that you’re taking this drug.
Keflex can also have a bad interaction with a drug called dofetilide. It may also react poorly when the patient is taking metformin. This common treatment for diabetes is sometimes given to those on metformin, but it requires a very careful dosing strategy. These two drugs used together can cause a decrease in the renal clearance of the diabetes medication.
Another drug that can be a problem with Keflex is probenecid. This medication can stop Keflex from being renally excreted. It’s not recommended for these two medications to be used at the same time.
