Cephadex 500mg for Bacterial Infections — Trusted Generic Keflex
Cephadex 500mg is a first-generation cephalosporin antibiotic containing cephalexin, manufactured by Cipla, India. It is effective against a wide range of gram-positive bacterial infections, including skin, soft tissue, respiratory, and urinary-tract infections.
What is Cephadex 500mg?
Cephadex 500mg is a prescription antibiotic capsule or tablet containing 500mg of cephalexin monohydrate. It belongs to the first-generation cephalosporin class of beta-lactam antibiotics and has been in clinical use for over 50 years. It remains a first-choice antibiotic for many common bacterial infections, particularly those caused by gram-positive organisms such as Staphylococcus aureus and Streptococcus species. It is the generic equivalent of Keflex and is prescribed globally for skin, respiratory, and urinary tract infections.
Manufacturing details: Cephadex 500 mg is manufactured by Cipla, a leading Indian pharmaceutical company.
The active component cephalexin & its mode of action
Cephalexin works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) on the inner surface of the bacterial cell membrane, blocking the final transpeptidation step of peptidoglycan synthesis. This process cross-links the bacterial cell wall. Without a structurally intact cell wall, bacteria cannot maintain osmotic stability and ultimately lyse (burst). Cephalexin is bactericidal, meaning it kills bacteria rather than merely inhibiting their growth. It is most effective against aerobic gram-positive bacteria but has some activity against gram-negative organisms. It is resistant to many penicillinases but susceptible to some extended-spectrum beta-lactamases.
Clinical uses of cephalexin
- Skin and soft tissue infections, including impetigo, cellulitis, and wound infections
- Upper respiratory tract infections, including streptococcal pharyngitis and tonsillitis
- Otitis media (middle ear infection)
- Bone infections (osteomyelitis) caused by susceptible organisms
- Urinary tract infections (UTIs), including cystitis
- Dental and oral infections
- Prophylaxis before dental procedures in patients with certain cardiac conditions
- Mild community-acquired pneumonia caused by susceptible organisms
Key benefits of cephalexin
- Bactericidal activity ensures rapid bacterial eradication
- Well-absorbed orally with reliable bioavailability regardless of food intake
- Effective in patients with penicillin allergy (with caution — cross-reactivity risk is low)
- Short treatment courses (5–10 days) for the most common infections
- Excellent safety profile with over 50 years of clinical data
- Relatively low cost compared to newer antibiotics with similar indications
- Multiple dosing schedules (twice or four times daily) to suit the patient's lifestyle
Brand vs Generic differences
Cephadex 500mg is the generic equivalent of Keflex 500mg. Both contain cephalexin 500mg as the active ingredient and are subject to the same bioequivalence requirements. Cipla, India, is a globally operating pharmaceutical manufacturer of Cephadex with a strong track record of quality assurance. The therapeutic effect, absorption profile, and safety of Cephadex 500mg are equivalent to Keflex, but at a dramatically lower price, making it an ideal choice for patients and healthcare systems seeking cost savings without compromising antibiotic therapy outcomes.
Dosing schedule for cephalexin capsules
The usual adult dose of Cephadex or Keflex is 250–500mg every 6 hours (four times daily) or 500mg every 12 hours (twice daily) for most infections, depending on severity. For skin infections, 500mg twice daily for 5–7 days is commonly prescribed. For urinary tract infections, 500mg twice daily for 3–7 days may suffice. For more severe infections, dosing may be increased. Cephadex 500mg may be taken with or without food, though food reduces the risk of nausea. Store at room temperature below 30°C. Keep capsules in a dry place away from moisture.
Alternative medicines & strengths of cephalexin on ReliableRxPharmacy
ReliableRxPharmacy also offers Cipmox 250mg and Cipmox 500mg (Amoxicillin) for patients requiring penicillin-class antibiotics, and Cipmox CV 625mg (amoxicillin-clavulanate) for broader or resistant infections. Azithral 250mg or 500mg (Azithromycin) is an option for patients with true beta-lactam allergy. Discuss antibiotic selection with your physician or pharmacist.
Important precautionary measures for using cephalexin capsules
Cephadex 500mg or Keflex should not be used in patients with known hypersensitivity to cephalosporin antibiotics. A small degree of cross-reactivity exists with penicillins; patients with a history of severe penicillin allergy (anaphylaxis) should use cephalosporins with caution. Dose reduction is required in patients with significant renal impairment (creatinine clearance below 30 mL/min). Drug interactions include warfarin (increased anticoagulant effect), metformin (increased plasma levels in high-dose cephalexin), and probenecid (which delays renal excretion, increasing cephalexin concentrations). Clostridioides difficile-associated diarrhoea is a risk with any antibiotic; report persistent diarrhoea to your doctor.
Side effects related to cephalexin capsules
Cephadex 500mg or Keflex is generally very well tolerated. The most common side effects of antibiotics are gastrointestinal, including nausea, diarrhoea, and abdominal discomfort. These are usually mild and self-limiting. Headache, dizziness, and fatigue are less common. Skin rashes, including urticarial rashes, may occur in susceptible individuals and should be reported to a doctor promptly. Serious adverse effects are rare but include anaphylaxis, severe skin reactions (Stevens-Johnson syndrome), haemolytic anaemia, and antibiotic-associated colitis caused by C. difficile. Patients should complete the full prescribed course to minimise the risk of treatment failure and antibiotic resistance.

What is Cephadex 500mg used for?
Cephadex 500mg contains cephalexin, an antibiotic (medicine that kills bacteria) used to treat bacterial infections. Your doctor may prescribe it for skin infections, urinary tract infections, ear infections, throat infections, or bone infections. It works by stopping bacteria from growing and spreading in your body. Take it exactly as your doctor directs, even if you feel better before finishing the full course. Always complete the entire treatment to prevent the infection from returning.
How does Cephadex 500mg work in the body?
Cephadex 500mg contains cephalexin, an antibiotic that kills bacteria by breaking down their cell walls. Your body cannot repair these damaged walls, so the bacteria die. Cephadex works against many common bacterial infections, including skin, urinary tract, and respiratory infections. It does not work against viral infections like colds or flu. The medicine enters your bloodstream after you swallow it and spreads throughout your body to reach infected areas.
How much Cephadex 500mg should I take, and how often?
Take one Cephadex 500mg tablet by mouth every six hours, which equals four tablets daily. However, your doctor may adjust this based on the infection type and severity. Always follow the exact dose and frequency your doctor prescribed, as it's tailored to your specific condition. Complete the full course even if you feel better. Never change your dose without consulting your doctor first.
How long should I keep using Cephadex 500mg?
You should take Cephadex 500mg for the full length of time your doctor prescribed, even if you feel better before finishing. This is usually 7–10 days for most infections. Stopping early allows bacteria to survive and return, making the infection worse or harder to treat. Always complete the entire course unless your doctor tells you to stop. If you have concerns about how long to continue, contact your doctor or pharmacist.
What things can affect how well Cephadex 500mg works?
Several factors can affect how well Cephadex works. Taking it with food may slow absorption, so take it on an empty stomach or with a light meal as directed. Completing the full course is essential—stopping early reduces effectiveness even if you feel better. Certain medicines, particularly probenecid (used for gout), can interfere with how your body processes Cephadex. Your kidney function also matters; if your kidneys don't work properly, the medicine may build up in your system. Always tell your doctor about other medicines you take and any kidney problems before starting Cephadex.
How quickly will I notice Cephadex 500mg working?
You may notice improvements within 2–3 days of taking Cephadex 500mg, depending on your infection type. However, complete relief usually takes 7–10 days of finishing your full course. Some infections clear faster than others. Continue taking all your tablets as prescribed, even if you feel better earlier, to prevent the infection from returning. If you don't see improvement after 3–4 days, contact your doctor.
Are there any serious warning signs I should watch out for with Cephadex 500mg?
Stop taking Cephadex and seek immediate medical help if you experience severe allergic reactions (difficulty breathing, throat swelling, severe rash), severe diarrhoea, yellowing of skin or eyes, unusual bruising, or signs of severe infection worsening instead of improving. These are rare but serious. Contact your doctor right away if you develop any of these symptoms. Do not stop taking your medicine without medical advice unless symptoms are life-threatening.
Is it safe to use Cephadex 500mg for a long period of time?
Long-term use of Cephadex 500mg should only happen under your doctor's supervision. Cephalexin (the active ingredient) is generally safe for extended treatment of certain infections, but prolonged use can increase the risk of side effects like digestive problems or allergic reactions. Your doctor will decide if long-term treatment is necessary for your condition and monitor you regularly. Never continue taking Cephadex beyond the prescribed duration without consulting your doctor, as this may also promote antibiotic resistance.
Which medicines should I avoid while using Cephadex 500mg?
Cephalexin can interact with certain medicines. Avoid taking probenecid (used for gout), as it reduces how your body clears this antibiotic. Live vaccines [vaccines made from weakened virus] may not work properly while you're taking Cephadex. If you take metformin (for diabetes) or digoxin (for heart conditions), your doctor should monitor you closely. Always tell your pharmacist and doctor about all medicines, supplements, and herbal products you use. Do not stop or change any medicine without speaking to your doctor first.
Can I use Cephadex 500mg alongside my other medicines or supplements?
Before taking Cephadex 500mg with other medicines or supplements, speak with your doctor or pharmacist. Some drugs can interact with cephalexin (the active ingredient in Cephadex), affecting how well either medicine works or increasing side effects. This includes certain blood thinners, some other antibiotics, and certain supplements. Your pharmacist can check all your current medicines and flag any potential problems. Never start or stop any medicine without consulting your doctor first.
Do I need a different dose of Cephadex 500mg if I have kidney or liver problems?
Your dose may need to be adjusted if you have kidney or liver problems, as these organs help your body process Cephadex. Kidney problems are particularly important—your doctor may lower your dose or increase the time between doses if your kidneys aren't working well. Liver problems can also affect how your body handles this medicine. Don't change your dose yourself; tell your doctor about any kidney or liver issues before starting Cephadex so they can prescribe the right amount for you.
Is Cephadex 500mg safe to take during pregnancy or while breastfeeding?
Cephadex 500mg contains cephalexin, a type of antibiotic. Cephalexin is generally considered safe during pregnancy and while breastfeeding, as only small amounts pass into breast milk. However, you should only take this medicine during pregnancy or while nursing if your doctor has specifically prescribed it for you and confirmed the benefit outweighs any risk. Always tell your healthcare provider you are pregnant or breastfeeding before starting any antibiotic. Do not stop taking a prescribed course without medical advice.
What should I discuss with my doctor before starting Cephadex 500mg?
Before starting Cephadex 500mg, tell your doctor if you have ever had an allergic reaction to penicillin or cephalosporin antibiotics (medicines that fight bacterial infections), as you may be allergic to this medicine too. Mention any kidney problems, as your dose may need adjusting. Let your doctor know about all medicines you take, including over-the-counter ones. If you're pregnant, breastfeeding, or planning to become pregnant, discuss this with your doctor. Also mention if you have severe diarrhoea or stomach problems.
Which strength of Cephadex 500mg is most commonly recommended?
Cephadex 500mg is the most commonly recommended strength for most infections in adults and older children. Your doctor will prescribe this dose based on the type and severity of your infection, your age, weight, and kidney function. The standard adult dose is usually one 500mg tablet taken three to four times daily. However, some infections may require different dosing, so always follow your doctor's instructions rather than assuming the 500mg strength is right for you.
How should I store Cephadex 500mg at home, and what happens if it expires?
Store Cephadex 500mg in a cool, dry place away from direct sunlight and heat. Keep it at room temperature and out of reach of children. Do not freeze. Check the expiry date on your pack before taking each dose. Using expired medicine may not work properly and could be unsafe. If your Cephadex has expired, do not take it—ask your pharmacist how to safely dispose of it and get a fresh supply.
