Common use

Keftab (cephalexin) is a trusted cephalosporin antibiotic that works by killing, fighting, and stopping the growth of bacteria in the body. When you buy Keftab online, you receive a first-generation cephalosporin with proven efficacy against a wide range of bacterial infections. This Keftab generic medication contains cephalexin as its active ingredient, offering the same reliable antibacterial action as the original brand at a more affordable price.

This cephalosporin antibiotic is prescribed for many types of bacterial infections, including upper respiratory infections (sinusitis, pharyngitis), ear infections (otitis media), skin infections (cellulitis, impetigo, wound infections, abscesses), UTI treatment (urinary tract infections including cystitis and pyelonephritis), bone infections (osteomyelitis), and strep throat. Keftab is particularly valued for its effectiveness against Streptococcus and Staphylococcus species, which are responsible for the majority of skin and soft tissue infections.

It is important to understand that Keftab will not work against viral infections such as the common cold, flu, or COVID-19. Using antibiotics unnecessarily contributes to antibiotic resistance, a growing global health concern. Always use this cephalosporin antibiotic only when prescribed by a qualified healthcare provider for a confirmed or strongly suspected bacterial infection. If you need to buy cephalexin for a diagnosed bacterial infection, Keftab offers a time-tested, effective treatment option trusted by physicians worldwide.



Dosage and direction

Take Keftab (cephalexin) exactly as prescribed by your doctor. Do not take a larger dose or use it for longer than recommended, as this will not make the antibiotic more effective and may increase the risk of side effects or contribute to antibiotic resistance.

Take Keftab with a full glass of water. If using the dispersible tablet formulation, dissolve the tablet in a small amount of water (about 2 teaspoonfuls), stir the mixture, and drink all of it immediately. To ensure you receive the entire dose, add a little more water to the glass, swirl gently, and drink again. Do not swallow or chew a dispersible tablet whole.

Complete the full course of this cephalosporin antibiotic as prescribed, even if your symptoms improve before all the medication is finished. Stopping treatment early can allow surviving bacteria to multiply and potentially cause a more resistant infection. Typical treatment courses range from 7 to 14 days depending on the type and severity of the bacterial infection.

Be aware that Keftab may cause unusual results with certain medical tests, including urine glucose tests. Inform any healthcare provider who treats you that you are currently taking this antibiotic medication.



Precautions

Before you buy Keftab online, tell your doctor if you are allergic to cephalexin or to any similar cephalosporin antibiotics (including Ceclor, Ceftin, Cefzil, Duricef, Fortaz, Omnicef, Spectracef, Suprax, and others). Cross-reactivity with penicillin allergies is possible, so inform your doctor about any penicillin sensitivities as well.

Tell your healthcare provider if you have kidney or liver disease, a gastrointestinal disorder such as colitis, diabetes, or if you are malnourished. These conditions may affect how your body processes cephalexin and may require dosage adjustments for safe UTI treatment or skin infection management.

Take Keftab with food if it causes stomach upset. Maintain adequate hydration throughout your treatment course. If you develop severe, watery, or bloody diarrhea during or after treatment, contact your doctor immediately, as this could indicate Clostridioides difficile-associated colitis, a serious but treatable intestinal condition.

Inform your doctor if you are pregnant, planning to become pregnant, or breast-feeding, as the risks and benefits of this cephalosporin antibiotic should be carefully evaluated.



Contraindications

Keftab is contraindicated in patients with known allergy to cephalexin, other cephalosporin antibiotics, or penicillins (due to cross-reactivity risk). Caution is required in patients with kidney or liver disease, intestinal disorders such as colitis, diabetes, malnutrition, and in pregnant or breastfeeding women. This Keftab generic should be used with particular care in patients with a history of gastrointestinal disease, especially antibiotic-associated colitis.



Possible side effects

Seek emergency medical attention if you experience signs of an allergic reaction: hives, difficulty breathing, or swelling of the face, lips, tongue, or throat. These reactions, while rare, require immediate treatment.

Contact your doctor promptly if you experience: watery or bloody diarrhea, seizures (convulsions), fever, sore throat, severe blistering or peeling skin rash, pale or yellowed skin, dark colored urine, confusion, unusual weakness, easy bruising or bleeding, hallucinations, agitation, or significant changes in urination patterns.

Less serious and more common side effects of this cephalosporin antibiotic include mild nausea, vomiting, diarrhea, stomach discomfort, dizziness, tired feeling, joint pain, or vaginal itching and discharge. These effects are usually temporary and resolve after completing the course of bone infection or UTI treatment.



Drug interactions

Before starting Keftab, inform your doctor about all medications you are currently taking, especially:

* Blood thinners such as warfarin (Coumadin) — cephalexin may enhance anticoagulant effects, increasing bleeding risk

* Metformin (Fortamet, Glucophage, Riomet, and combination products) — interaction monitoring may be needed

* Probenecid (Benemid) — can increase cephalexin blood levels by reducing kidney excretion, potentially intensifying side effects

* Live vaccines — this antibiotic may reduce vaccine effectiveness

Always provide a complete list of your prescription medications, over-the-counter drugs, vitamins, minerals, and herbal products to your doctor. Do not start any new medication during your bacterial infection treatment without consulting your healthcare provider.



Missed dose

Take the missed dose of Keftab as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take extra antibiotic medicine to make up for a missed dose, as this will not improve effectiveness and may cause unnecessary side effects.



Overdose

Seek emergency medical attention if you think you have taken too much Keftab. Overdose symptoms of this cephalosporin antibiotic may include severe nausea, vomiting, stomach pain, diarrhea, and blood in your urine. Prompt medical evaluation is essential for appropriate supportive care.



Storage

Store Keftab tablets and capsules at room temperature, away from moisture and heat. Keep this bacterial infection treatment out of reach of children and pets. Throw away any unused reconstituted liquid medication after 14 days, even if some remains.
