Common uses of Keflex (cephalexin) for bacterial infections

Keflex, the brand name for cephalexin, is a first-generation cephalosporin antibiotic used to treat susceptible bacterial infections. Clinicians often prescribe it for skin and soft tissue infections such as cellulitis, impetigo, and infected wounds, where common culprits include streptococci and methicillin-sensitive Staphylococcus aureus. Keflex is also frequently used for streptococcal pharyngitis (strep throat) in patients who cannot take penicillin, for certain respiratory infections like uncomplicated bacterial sinusitis, and for acute otitis media.

In the urinary tract, Keflex can treat uncomplicated UTIs caused by susceptible organisms such as E. coli, Proteus mirabilis, and Klebsiella pneumoniae. It may also be used for bone infections (osteomyelitis) in specific scenarios and as prophylaxis for certain dental or procedural indications when recommended by a clinician. Its spectrum targets many Gram-positive organisms and some Gram-negative bacteria, but not all. Culture and sensitivity testing, when available, guide more precise therapy.

Because Keflex, like all antibiotics, does not work against viruses (for example, colds, most sore throats, or the flu), using it only when bacterial infection is likely helps prevent antibiotic resistance and unnecessary side effects. The decision to use cephalexin should be based on clinical evaluation, local resistance patterns, and patient-specific risks.

 

 

Keflex dosage and directions: how to take cephalexin safely

Your prescriber will choose a dose and duration based on the infection type, its severity, your kidney function, and age. Keflex is available as capsules, tablets, and oral liquid suspension. Many adult regimens use 250 mg to 500 mg taken every 6 to 12 hours, with total daily doses often ranging from 1 to 4 grams. For strep throat and skin infections, common adult dosing is 500 mg every 12 hours or 250–500 mg every 6 hours. More severe infections may require higher doses within approved limits. In children, dosing is weight-based and divided throughout the day.

Keflex can be taken with or without food; taking it with a snack may reduce stomach upset. Swallow capsules with a full glass of water. If you are using the oral suspension, shake well before each dose and measure with a marked device rather than a household spoon to ensure accuracy. Take doses at evenly spaced intervals to maintain steady antibiotic levels in your system.

Always complete the full course exactly as prescribed, even if you feel better sooner. Stopping early can allow the infection to return and may contribute to antibiotic resistance. Do not save leftover antibiotics or share them with others.

 

 

Precautions before using Keflex

Tell your clinician and pharmacist if you have ever had an allergic reaction to cephalexin, other cephalosporins (such as cefazolin or cefuroxime), or penicillins. Cross-reactivity can occur in people with a history of immediate hypersensitivity to penicillin, so your care team may choose an alternative antibiotic if your allergy was severe (for example, anaphylaxis, hives with breathing difficulties, or angioedema).

If you have kidney problems, your dose may need adjustment to prevent drug accumulation. Older adults and those with significant renal impairment require careful monitoring. Let your care team know if you are pregnant, planning to become pregnant, or breastfeeding. Cephalexin has been widely used during pregnancy and is generally considered compatible; during breastfeeding, small amounts pass into milk and infants should be observed for loose stools, diaper rash, or thrush.

Report a history of severe intestinal disease, particularly Clostridioides difficile-associated diarrhea. Like many antibiotics, Keflex can disrupt the gut microbiome and, rarely, trigger C. difficile overgrowth, leading to persistent or severe diarrhea. If you develop watery or bloody stools, abdominal cramping, or fever during or after treatment, seek medical care promptly.

Discuss all prescription drugs, OTC medications, and supplements you take. Certain interactions can alter how cephalexin or other drugs work, and timing adjustments or monitoring may be recommended.

 

 

Contraindications to Keflex

Keflex is contraindicated in individuals with a known serious hypersensitivity to cephalexin or other cephalosporin antibiotics. Patients with a documented history of severe, immediate-type hypersensitivity to penicillin may be at increased risk for reactions to cephalosporins; in such cases, the risks and benefits must be weighed carefully, and alternative agents may be preferred.

Additionally, if you have experienced severe cutaneous adverse reactions to beta-lactam antibiotics (such as Stevens-Johnson syndrome or toxic epidermal necrolysis), cephalexin should be avoided. For those with significant renal impairment without the ability to monitor and adjust dosing, using Keflex without guidance is not appropriate.

 

 

Possible side effects of Keflex

Most people tolerate Keflex well. Common side effects include gastrointestinal upset such as nausea, vomiting, abdominal discomfort, and diarrhea. Headache, dizziness, and fatigue can occur. A mild skin rash or itching may develop and typically resolves after the drug is discontinued; inform your clinician if rash appears, as it may signal hypersensitivity.

Less common effects include vaginal yeast infection or oral thrush due to changes in normal flora. Laboratory changes like transient increases in liver enzymes or slight shifts in blood counts are occasionally seen. Rare but serious adverse reactions include severe allergic reactions (anaphylaxis), angioedema, severe skin reactions, hemolytic anemia, interstitial nephritis, and seizures, particularly in the context of renal insufficiency or very high doses. Seek immediate medical attention if you experience wheezing, swelling of the face or throat, fainting, blistering skin, intense rash, or difficulty breathing.

Any persistent diarrhea, especially if watery or bloody, may indicate C. difficile-associated colitis and needs urgent evaluation. Probiotics may help with antibiotic-associated GI symptoms in some individuals, but discuss this with your clinician to ensure safety and appropriate timing.

 

 

Drug interactions with Keflex

Cephalexin has a favorable interaction profile, but important interactions exist. Concomitant use with warfarin or other anticoagulants may increase bleeding risk; close INR monitoring is advisable when starting or stopping antibiotics. Probenecid can increase cephalexin levels by reducing renal excretion. Cephalexin can elevate metformin concentrations in some cases; monitoring for hypoglycemia or gastrointestinal side effects may be warranted.

Antibiotics can reduce the effectiveness of live attenuated typhoid vaccine; avoid administering the vaccine during and shortly after antibiotic therapy. While food does not meaningfully reduce cephalexin absorption, taking the drug alongside certain minerals or binding agents rarely poses issues compared with some other antibiotics, though spacing doses away from large amounts of zinc, iron, or calcium may minimize any theoretical absorption concerns.

Cephalexin can interfere with certain laboratory tests, including causing false-positive urine glucose tests when non-enzymatic methods are used. Inform your care team and laboratory if you are on Keflex so results are interpreted correctly.

 

 

Missed dose: what to do if you forget a dose of Keflex

If you miss a dose, take it as soon as you remember. If it is close to the time of your next dose, skip the missed dose and resume your regular schedule. Do not double up to “catch up,” as taking doses too close together may increase side effects without improving effectiveness. Keeping a dosing reminder on your phone or using a pill organizer can help maintain consistent antibiotic levels, which is essential for clearing infection.

 

 

Overdose: signs, symptoms, and immediate steps

Taking more cephalexin than prescribed can increase the risk of nausea, vomiting, diarrhea, abdominal pain, and, in severe cases, neurological symptoms such as agitation, confusion, or seizures, especially in those with kidney impairment. If an overdose is suspected, contact your clinician, call Poison Control at 1-800-222-1222 (U.S.), or seek emergency care immediately. Supportive treatment is typically provided, and in the context of significant renal dysfunction, hemodialysis may enhance elimination under professional supervision.

 

 

Storage and handling of Keflex

Store Keflex capsules or tablets at room temperature, ideally 68°F to 77°F (20°C to 25°C), away from moisture, excess heat, and direct light. Keep the bottle tightly closed and out of reach of children and pets. For the oral suspension, your pharmacist will prepare the medication by mixing the powder with water; the reconstituted suspension is typically kept refrigerated and discarded after 14 days. Shake the suspension well before each use to ensure even distribution.

Never use expired antibiotics, and do not flush unused medication. Ask your pharmacist about take-back programs or safe disposal options in your community.
