Cephalexin is a common antibiotic used for various bacterial issues. Preventing pathogens from maintaining their protective walls, the substance helps the immune system eliminate the infection.
If you’ve ever taken a pill to clear up a bacterial infection, the active ingredient might be cephalexin. It belongs to the cephalosporin family, a group of beta-lactam antibiotics that fight bacteria. In Australia you’ll find it as the active compound in medicines such as Keftab.
When you develop common infections, this medicine may help your body fight them. It is often used for skin infections that cause redness, swelling, or pus. It can also address ear infections that make your ear painful and hearing muffled. Sore throats caused by bacterial irritation, uncomfortable urination from a bladder infection, and bone infections that bring persistent aches are other situations where it may be chosen. Children and adults alike may be prescribed it, depending on the infection type and severity.
After you swallow the tablet, it moves into your bloodstream and reaches the site of infection. The drug interferes with the bacteria’s ability to build their protective cell wall, which is like dismantling the bricks of a house, causing the bacteria to break apart and die. This helps your immune system clear the infection more quickly.
Before you start taking this antibiotic, there are a few things to keep in mind. People who are pregnant, breastfeeding, or have kidney problems should use extra caution, and anyone with a known allergy to penicillin or other cephalosporins should avoid it. Alcohol generally does not change how the medicine works, but it can increase stomach upset. Certain drug classes-such as blood thinners, antacids that contain aluminium or magnesium, and some oral contraceptives-may affect how well cephalexin works, so check the medication label for details.
Most people notice only mild and temporary effects.
Older adults, people with kidney impairment, and those who have experienced allergic reactions to similar antibiotics are more likely to notice side effects. Individuals who have taken antibiotics frequently may also have a higher chance of developing serious gut-related issues.
Keep your cephalexin tablets out of reach of heat, moisture, and direct sunlight. Store them at room temperature in a dry place, and make sure the bottle is tightly closed. Treatment length can vary; some courses last a few days while others may run for several weeks, depending on the infection. For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
