Keflex Information

Cephalexin at CanadaPharmacyOnline.com

The manufacturer of Keflex (cephalexin) was historically Eli Lilly and Company, but the brand-name version has since changed hands several times and has regional partners. In Canada, Keflex has been marketed by companies like Pendopharm (a division of Pharmascience Inc.). While the brand-name version is well known in antibiotic therapy, its status can be "dormant" in certain regions, as the market has largely shifted toward high-quality generics. The brand Keflex is currently unavailable (at this pharmacy).

Generic cephalexin is widely produced by numerous manufacturers that meet the strict regulatory standards for safety and quality set by Health Canada. Common generic producers include Apotex, Teva, and Sandoz. Generic cephalexin is sourced from manufacturers that meet applicable regulatory standards. The specific manufacturer of your dispensed medication may vary.

Important Information about Generic Cephalexin

Generic cephalexin contains the same active ingredient as brand-name Keflex. It must meet the same effectiveness and quality standards. This means it is designed to work like Keflex. Studies have shown that generic cephalexin is bioequivalent to brand-name Keflex, meaning it has similar absorption and achieves comparable blood concentrations. However, individual responses to medication can vary due to factors such as metabolism, genetics, and other health conditions.

Dosage:

Cephalexin is available in the following oral strengths and forms:
• Capsules: 250 mg and 500 mg (most common).
• Tablets: 250 mg and 500 mg.

The standard adult dosage is typically 250 mg every 6 hours or 500 mg every 12 hours. However, more severe infections may require higher doses as determined by your physician.

Usage:

Keflex is a first-generation cephalosporin antibiotic used to treat a wide range of bacterial infections in adults and children. It is commonly prescribed for respiratory tract infections, such as pneumonia and bronchitis, as well as middle ear infections (otitis media) and bone infections. It is also a frequent choice for treating skin and skin structure infections, such as cellulitis, and urinary tract infections (UTIs), such as cystitis. Because it is an antibiotic, Keflex is effective only against bacterial infections. It will not work for viral illnesses like the common cold or flu. It is vital to complete the full course of treatment as directed by your doctor, even if you feel better after a few days, to ensure the infection is completely cleared and to prevent the development of antibiotic resistance.

Mechanism of Action
Cephalexin, the active agent in Keflex, works by interfering with the way bacteria build their protective cell walls. Bacteria rely on a strong cell wall to maintain their shape and survive the pressure of their internal environment. The medication targets and inhibits specific proteins called penicillin-binding proteins (PBPs), which are responsible for cross-linking the peptidoglycan strands that form the "mesh" of the cell wall. By inhibiting this structural reinforcement, Keflex destabilizes the bacterial cell wall and eventually causes it to burst (a process called cell lysis). This bactericidal (bacteria-killing) action effectively eliminates the infection. Because human cells lack cell walls or peptidoglycan, the medication can target bacteria without harming the patient's own cells.

Take Keflex exactly as your doctor prescribes. You can take this medication with or without food. However, taking it with a meal may help if the antibiotic causes stomach upset.

The information below summarizes some, but not all, potential side effects, risks, and interactions.Before starting Keflex, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Keflex (cephalexin). It is not an exhaustive list, and individual reactions can vary.

Common side effects: These are common side effects of Keflex; other side effects are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Diarrhea (the most common side effect)
• Dizziness or fatigue
• Nausea or vomiting
• Stomach pain or indigestion
• Vaginal itching or yeast infection

Serious Side Effects: Seek immediate medical attention or call emergency services if you experience any of the following symptoms:
• Anaphylaxis: Severe allergic reaction involving hives, swelling of the face or throat, and difficulty breathing.
• C. diff-associated Diarrhea: Severe, watery, or bloody diarrhea with stomach cramps and fever, which can occur even weeks after treatment.
• Liver or Kidney Issues: Dark urine, yellowing of the skin/eyes, or decreased urination.
• Seizures: Especially in patients with existing kidney problems.
• Severe Skin Reactions: Fever, sore throat, and a red or purple skin rash that blisters and peels.

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Keflex, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Do not take Keflex/cephalexin if:
• Allergies: You have a known hypersensitivity to cephalexin or other cephalosporin antibiotics (e.g., Ceftin, Cefzil).
• Severe Penicillin Allergy: Use with extreme caution if you have a history of severe, immediate allergic reactions to penicillin, as cross-reactivity may occur in a small percentage of patients.

Tell your doctor about all of your medical conditions, past and present, before starting Keflex. This is crucial as certain conditions affect the drug's safety.
• History of Colitis: Tell your doctor if you have a history of severe intestinal inflammation or chronic diarrhea.
• Kidney Disease: You may need a lower dose or a different dosing schedule if your kidney function is impaired.
• Seizure Disorders: This medication should be used with caution as it may increase the risk of seizures in certain patients.

Drug Interactions:

Before taking Keflex, discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please visit the product monograph at https://pdf.hres.ca/dpd_pm/00045523.PDF.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, herbal supplements, recreational drugs, and any significant dietary changes, as these may interact with Keflex. Keflex may interact with other medicines, including but not limited to:
• Blood Thinners: Like many antibiotics, Keflex can increase the effects of anticoagulants like warfarin, increasing the risk of bleeding.
• Lab Tests: Tell laboratory personnel you are taking Keflex, as it can cause false-positive results on certain urine glucose tests and Coombs tests.
• Metformin: Cephalexin can increase metformin levels in your blood, which may require a dose adjustment of your diabetes medication.
• Probenecid: This medication for gout can slow the removal of cephalexin from your body, increasing the risk of side effects.

Pregnancy and Breastfeeding:

Keflex is generally considered safe for use during pregnancy when a bacterial infection is present. Decades of clinical use have shown no evidence of harm to the fetus. Small amounts of cephalexin pass into breast milk. While usually safe, monitor the infant for diarrhea, rash, or thrush. Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

Use in Children:

Keflex is approved for use in children aged 1 year or older. For pediatric patients, the doctor carefully calculates the dose based on the child's weight and the type of infection being treated.
