Common use

Keftab (cephalexin) is commonly prescribed for the treatment of bacterial infections including respiratory tract infections (e.g., bronchitis, pneumonia), skin and soft tissue infections, otitis media (middle ear infection), bone infections, and genitourinary tract infections (e.g., cystitis, prostatitis). It is also used for dental infections and as prophylactic treatment prior to certain surgeries to prevent postoperative infections.

Dosage and direction

The dosage of Keftab must be individualized based on the infection type, severity, and patient factors such as age, renal function, and weight (for pediatric patients). For most infections in adults, the typical dose is 250 mg to 500 mg orally every 6 hours. For more severe infections, doses up to 4 grams daily may be used, divided into 2–4 doses. Pediatric dosing is usually 25–50 mg/kg/day divided into 2–4 doses. The medication should be taken with food to minimize gastrointestinal upset. Complete the full course of therapy even if symptoms improve earlier to prevent resistance.

Precautions

Before taking Keftab, inform your healthcare provider if you have a history of kidney disease, gastrointestinal disease (especially colitis), or allergies to antibiotics. Use with caution in patients with a history of penicillin allergy, as cross-reactivity may occur. Prolonged use may result in fungal or bacterial superinfection. Keftab should be used during pregnancy only if clearly needed and under medical supervision. It is excreted in breast milk; consult a doctor before breastfeeding.

Contraindications

Keftab is contraindicated in patients with known hypersensitivity to cephalexin or any cephalosporin antibiotics. It should not be used in patients with a history of severe allergic reactions (e.g., anaphylaxis) to penicillins or other beta-lactam antibiotics due to potential cross-sensitivity.

Possible side effect

Common side effects may include diarrhea, nausea, vomiting, abdominal pain, and indigestion. Less frequently, patients may experience dizziness, fatigue, headache, or vaginal itching or discharge. Allergic reactions such as rash, urticaria, or itching may occur. Serious side effects are rare but can include severe diarrhea (possibly indicating Clostridium difficile-associated diarrhea), hepatotoxicity, blood dyscrasias, or interstitial nephritis. Seek medical attention if any severe or persistent side effects occur.

Drug interaction

Keftab may interact with probenecid, which can increase cephalexin blood levels. Concurrent use with metformin may increase the risk of lactic acidosis. It may also interact with oral anticoagulants (e.g., warfarin), potentially enhancing anticoagulant effect. Live bacterial vaccines (e.g., typhoid vaccine) may have reduced efficacy if taken with antibiotics. Always inform your healthcare provider of all medications, including over-the-counter drugs and supplements.

Missed dose

If a dose of Keftab is missed, take it as soon as remembered unless it is almost time for the next dose. Do not double the dose to catch up. Maintaining consistent dosing intervals is important for optimal efficacy.

Overdose

Symptoms of overdose may include nausea, vomiting, epigastric distress, diarrhea, and hematuria. In case of suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and may include gastric lavage or hemodialysis in severe cases.

Storage

Store Keftab tablets at room temperature (15–30°C or 59–86°F) in a tightly closed container, away from light, moisture, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
