Also known as Keflex, cephalexin is an antibiotic medication that is used to treat various bacterial infections. With the online tele-healthcare trend becoming more and more common, it’s not unusual to ask whether you can get antibiotics like cephalexin online. The answer is yes, and it’s easy and convenient. Read on to learn more about how to make an appointment with an online doctor and get cephalexin online.

What is Cephalexin?

Cephalexin is an antibiotic that belongs to a class of drugs known as cephalosporins. Cephalosporins are similar to penicillin in terms of effectiveness and side effects. Cephalexin was approved by the Federal Drug Administration (FDA) in January 1971.

How Does Cephalexin Work?

Cephalexin works by slowing down or eradicating the growth of bacteria cells by keeping the bacteria from forming a cell wall.

In addition to keeping the contents of a cell together, a bacteria cell wall helps protect itself from the external environment and can’t survive without it. Cephalexin is especially effective in killing bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, E. coli, Staphylococcus aureus and others.

Cephalexin Dosage and Treatment

Cephalexin is commonly used to treat infections such as:

Cephalexin can come in the form of a tablet, capsule, or a suspension liquid. It should be taken by mouth either with or without food. Depending on your condition, you may commonly be prescribed a dosage of one pill every 6 to 12 hours over a course of 7 to 14 days.

An adult dose of cephalexin is typically 1 to 4 grams that are divided daily, usually about 250 mg every 6 hours. More serious infections may be treated at a dosage of 500 mg every 12 hours. Children are typically given between 25-100 mg a day in divided doses.

Follow your prescription directions carefully and don’t take more or less pills than your doctor has prescribed. Take your full course of cephalexin even if you start to feel better. Stopping your prescription in the middle of your prescribed course may not completely treat your infection and the bacteria can become resistant to the antibiotic.

Benefits of Cephalexin

Cephalosporin antibiotics such as cephalexin are considered broad spectrum antibiotics. This means that they are used to treat a wide variety of infections caused by many kinds of bacteria. It is sometimes referred to as a first-generation cephalosporin because it was one of the first cephalosporin antibiotics to be developed.


Side Effects of Cephalexin

Many people that use cephalexin do not experience serious side effects. However, you should tell your doctor if any of the following side effects become severe or do not go away:

Serious allergic reactions to cephalexin are rare. If you experience any of these symptoms, contact your doctor as soon as possible or seek emergency medical treatment:

  • Rash
  • Hives
  • Difficulty breathing
  • Difficulty swallowing
  • Wheezing
  • Swelling of the tongue, throat, lips, eyes, or face
  • Hallucinations
  • Bloody or watery stools
  • Fever while taking medication or for up to two months after finishing treatment

Considerations and Precautions of Cephalexin

Certain drugs can interact with cephalexin, such as blood-thinners, metformin, and probenecid. Talk with your doctor about any current medications you are taking, including any over-the-counter medications, herbal supplements, or vitamins.

Prolonged use of cephalexin can result in oral thrush or other yeast infections. Get in touch with your doctor if you notice a change in your vaginal discharge, white patches in your mouth or tongue, or any other new and unusual symptoms.

Cephalexin may rarely cause clostridium difficile-associated diarrhea because of a resistant bacteria. This can occur during treatment or after treatment has stopped. Tell your doctor if you develop abdominal pain, persistent diarrhea, or blood in your stool.

Some cephalosporins have been associated with triggering seizures, especially in people who have renal impairment. If a seizure occurs while taking cephalexin, stop taking your medication and call your doctor as soon as possible.

Patients who have renal or hepatic conditions, poor nutrition, or patients who receive anticoagulant medications may be at risk for prolonged prothrombin time. Patients with these conditions should be closely monitored.
