- Do not take a double dose to make up for a missed dose. Doing so may cause overdose and side effects. [7] X Research Sources
Understanding Cephalexin drug
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/25/Take-Cephalexin-Step-8-Version-2.jpg/v4-728px-Take-Cephalexin-Step-8- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/25/Take-Cephalexin-Step-8-Version-2.jpg/v4-728px-Take- Cephalexin-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Understand that Cephalexin is used to fight bacteria in the body. Cephalexins are known to be bactericidal, meaning their use is to inhibit or disrupt the cell wall of bacteria and cause the cell to explode or burst. [8] X Research Sources
- Cephalexin is effective against gram-positive bacteria. These bacteria include bacillus, corynebacterium, clostridium, listeria, staphylococcus, and streptococcus. [9] X Research Source
- Cephalexin is not effective in treating viral infections. It is also not used to treat methicillin-resistant Staphylococcus aureus (MRSA) infections. [10] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/09/Take-Cephalexin-Step-9-Version-2.jpg/v4-728px-Take-Cephalexin-Step-9- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/09/Take-Cephalexin-Step-9-Version-2.jpg/v4-728px-Take- Cephalexin-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Take Cephalexin to fight bacterial infections. Cephalexin is mainly used to fight bacterial infections. Infections can include bone and joint infections, pneumonia, skin and urinary tract infections, and otitis media.
- In some cases, Cephalexin is used as a prophylactic drug, which is used to prevent certain infections. For example, Cephalexin is used to prevent endocarditis (endocarditis) caused by bacterial infections. [11] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b0/Take-Cephalexin-Step-10-Version-2.jpg/v4-728px-Take-Cephalexin-Step-10- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b0/Take-Cephalexin-Step-10-Version-2.jpg/v4-728px-Take- Cephalexin-Step-10-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Be aware that improper use of Cephalexin can reduce its effectiveness. Taking Cephalexin when you don’t have an infection can make it less effective when you really need it. Cephalexin is also less effective if you do not take the full dose or cycle as prescribed by your doctor. [12] X Research Source
- Talk to your doctor if you still have symptoms of an infection after taking the medicine. [13] X Research Source
Talk to your doctor about Cephalexin
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/90/Take-Cephalexin-Step-11-Version-2.jpg/v4-728px-Take-Cephalexin-Step-11- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/90/Take-Cephalexin-Step-11-Version-2.jpg/v4-728px-Take- Cephalexin-Step-11-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Talk to your doctor about allergies (if any). Do not take Cephalexin if you are allergic to it. In most cases, subjects allergic to Cephalexin will also be allergic to other Cephalosporin antibiotics. [14] X Research Source
- Some drugs in the Cephalosporin class include Cefaclor, Cefadroxil, Cefdinir, Cefditoren, Cefixime, Cefprozil, Ceftazidime, and Cefuroxime.
- Cephalosporin drugs that begin with the letter “Cef”. Being aware of this helps you avoid medication if you have an allergy.
- Also, inform your doctor if you are allergic to Penicillin or Amoxicillin. People who are allergic to Penicillin or Amoxicilli have a higher risk of being allergic to Cephalexin. [15] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/54/Take-Cephalexin-Step-12-Version-2.jpg/v4-728px-Take-Cephalexin-Step-12- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/54/Take-Cephalexin-Step-12-Version-2.jpg/v4-728px-Take- Cephalexin-Step-12-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Talk to your doctor about any underlying medical conditions (if any). Cephalexin should not be used if you have certain underlying medical conditions. You should not take Cephalexin if you have kidney disease, liver disease, colitis, diabetes, and malnutrition. Most of these diseases alter the body’s ability to metabolize Cephalexin.
- For example, Cephalexin contains sugar, so people with diabetes should not take it. [16] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/57/Take-Cephalexin-Step-13-Version-2.jpg/v4-728px-Take-Cephalexin-Step-13- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/57/Take-Cephalexin-Step-13-Version-2.jpg/v4-728px-Take- Cephalexin-Step-13-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Talk to your doctor if you are pregnant. There are not many studies on the effects of Cephalexin on the fetus. Therefore, it is best to talk to your doctor about alternative medicines if you are pregnant. Pregnant women should take Cephalexin only when there is no other option. [17] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/ca/Take-Cephalexin-Step-14-Version-2.jpg/v4-728px-Take-Cephalexin-Step-14- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/ca/Take-Cephalexin-Step-14-Version-2.jpg/v4-728px-Take- Cephalexin-Step-14-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Talk to your doctor about other medications you are taking. Tell your doctor if you are taking other medicines than Cephalexin. Medicines can cause drug interactions with Cephalexin, which affects the effectiveness of Cephalexin.
- For example, some bacterial vaccines such as typhoid vaccine and BCG vaccine can be affected by Cephalexin. In addition, some studies have also shown that Cephalexin may affect the effectiveness of oral contraceptives. So you can still get pregnant if you take Cephalexin while you’re on birth control pills. [18] X Research Sources
- Other drugs that may interact with Cephalexin include Coumadin, Metformin, and Probenecid. [19] X Research Source

Talk to your doctor if you think Cephalexin is not suitable for you. If you feel you should not take Cephalexin, you should let your doctor know. Your doctor may reduce your dose or give you a new medication.
- Special tests such as skin tests may be done to determine if it is safe for you to take Cephalexin. [21] X Research Source
Know the signs to see a doctor
