What is Cephalexin?

Cephalexin is an antibiotic in the cephalosporin class. It targets bacteria by disrupting the construction of their cell walls. This weakens the bacteria and helps the body's immune system clear the infection. In online pharmacies you’ll see capsules and a powder for suspension for children. Dosing usually depends on age, weight, and the infection being treated.

How does it work?

The drug interferes with enzymes that build the bacterial wall. Without a strong wall, bacteria cannot grow and divide. The result is slower spread and easier healing. Cephalexin does not treat viral infections such as colds or flu, so it is important to use it only for bacterial infections as prescribed.

Common uses and dosing guidance

Cephalexin is often used for skin infections, throat infections, ear infections, and some urinary tract infections. Typical adult doses range from 250 mg to 500 mg every six hours, depending on severity. For children, the suspension dose is calculated by weight. Take it with a full glass of water and, if stomach upset occurs, consider taking it with food.

Who should avoid or use with caution

People with a history of severe allergy to penicillins or cephalosporins should not start cephalexin without medical advice. Tell your clinician about kidney disease, intestinal disorders, or prior allergic reactions. Use with caution in pregnant or breastfeeding individuals unless a clinician approves. Always inform online pharmacies of other medicines you take.

Potential side effects

Most people tolerate cephalexin well, but some may notice upset stomach, diarrhea, or skin rashes. Rarely, more serious allergic reactions can occur. If you develop quick swelling, trouble breathing, or a severe rash, seek urgent medical help. Prolonged diarrhea could indicate a superimposed infection and should be discussed with a pharmacist or doctor.

Drug interactions and advice

Cephalexin can interact with certain medications, such as other antibiotics, blood thinners, or medicines that affect gut bacteria. Alcohol does not directly interact, but it can worsen stomach upset. If you take other prescriptions, vitamins, or herbal products, share this with the online pharmacy team to adjust dosing if needed.

Storage, safety, and tips

Store capsules at room temperature away from moisture and heat. The suspension should be tightly closed and refrigerated after mixing; discard any unused portion after a specified period. Do not use Cephalexin past its expiration date. Keep it out of reach of children and do not share medicines with others.
