FAQ
Cephalexin is a cephalosporin antibiotic used to treat certain bacterial infections caused by susceptible organisms, including respiratory tract infections (such as streptococcal pharyngitis), otitis media, skin and skin-structure infections, urinary tract infections, and bone infections. It works by inhibiting bacterial cell-wall synthesis, which can kill susceptible bacteria.
Dosing depends on the infection, its severity, and kidney function. In adults and patients 15 years and older, common regimens include 250 mg every 6 hours or 500 mg every 12 hours; more severe infections may require higher doses, up to 4 g per day in divided doses. Duration is often 7 to 14 days, but your prescriber will set the exact course. Children typically receive weight-based dosing prescribed by a clinician.
Cephalexin is commonly available as capsules and as an oral suspension (liquid). Availability of tablets can vary by manufacturer and market; use the form your clinician prescribes and that your pharmacy dispenses.
Common side effects include nausea, diarrhea, stomach pain, and headache. Serious side effects can occur, including severe allergic reactions and severe or persistent diarrhea (which can be a sign of antibiotic-associated colitis). Seek urgent care for hives, swelling of the face/throat, trouble breathing, or fainting.
Yes. Cephalexin can interact with probenecid and may affect anticoagulants such as warfarin (monitoring may be needed). It can also interact with some diabetes medicines such as metformin in certain patients. Tell your clinician and pharmacist about all medicines and supplements you take.
Alcohol is not known to directly stop cephalexin from working, but drinking—especially heavy drinking—can worsen side effects like nausea, stomach upset, or dizziness and may slow recovery. If unsure, ask your clinician.
Tell your clinician if you have kidney disease, a history of severe antibiotic allergy, or a history of significant gastrointestinal disease (including prior antibiotic-associated colitis). Use antibiotics only for bacterial infections and take the full course as prescribed unless your prescriber tells you to stop.
Cephalexin is used in children and older adults, but dosing may need adjustment—especially in older adults or anyone with reduced kidney function. A clinician should determine the correct dose and schedule.
Cephalexin is a first-generation cephalosporin. It is often effective for susceptible Gram-positive bacteria and some Gram-negative bacteria, and is commonly used for skin infections and certain respiratory infections. It is not the best choice for every infection; selection depends on the suspected bacteria, local resistance patterns, and patient factors.
Yes. Misuse (such as taking antibiotics for viral illnesses, skipping doses, or stopping early) can promote resistance and make infections harder to treat. Take cephalexin exactly as prescribed and complete the course unless your prescriber advises otherwise.
No. Cephalexin does not treat viral infections such as colds or influenza. Antibiotics should only be used for bacterial infections.
Some people start to feel better within a couple of days, but improvement depends on the infection and severity. Contact your clinician if symptoms do not improve or worsen after 48–72 hours, or if you develop severe side effects.
Yes. Cephalexin is a prescription antibiotic in the US. Use it only under the direction of a licensed clinician.
Take the missed dose as soon as you remember. If it is close to your next scheduled dose, skip the missed dose and return to your regular schedule. Do not take two doses at the same time to make up for a missed one.
No. Stopping early can allow the infection to return and may contribute to antibiotic resistance. Finish the prescribed course unless your prescriber tells you to stop.
Yes. Allergic reactions can range from rash to severe reactions such as anaphylaxis. Seek urgent medical help for hives, swelling, dizziness/fainting, or trouble breathing. Tell your clinician if you have a history of penicillin or cephalosporin allergy.
Yes. Cephalexin can be taken with or without food. Taking it with food may help reduce nausea or stomach discomfort.
Cephalexin may be used during pregnancy and breastfeeding when clinically indicated, but you should discuss risks and benefits with your clinician. If breastfeeding, monitor the infant for diarrhea, rash, or thrush and contact a clinician if concerns arise.
Store capsules at controlled room temperature: 20°C to 25°C (68°F to 77°F), away from moisture and direct light. For oral suspension, follow the product directions; after mixing, many products should be refrigerated and any unused portion is typically discarded after 14 days.
Sometimes. A clinician or dentist may prescribe cephalexin for certain dental infections when antibiotics are indicated, but dental procedures (such as drainage or other treatment) may still be needed.
Yes. Antibiotics can disrupt normal flora and increase the risk of yeast overgrowth in some people. If you develop itching, unusual discharge, or other symptoms, contact your clinician.
Cephalexin inhibits bacterial cell-wall synthesis, which can lead to rupture and death of susceptible bacteria. It is generally more active against many Gram-positive organisms and has activity against some Gram-negative organisms.
