Cefaclor – Overview, Dosage, and Safety
When working with Cefaclor, a second‑generation cephalosporin used to treat a range of bacterial infections. Also known as Cefaclor, it belongs to the broader group of Cephalosporin antibiotics, beta‑lactam drugs that share a common ring structure and are prized for their broad spectrum activity. These antibiotics are often chosen when bacterial infections, such as bronchitis, sinusitis, or ear infections, need reliable coverage. Knowing how Cefaclor fits into this picture helps you decide when it’s the right fit.
Key Uses and How It Stacks Up Against Other Drugs
Cefaclor is most commonly prescribed for respiratory tract infections, skin infections, and uncomplicated urinary tract infections. Compared with older penicillins like Amoxicillin, Cefaclor often offers better coverage against gram‑negative organisms while still tackling many gram‑positive bugs. When a doctor needs a middle ground between narrow‑spectrum penicillins and the broader fluoroquinolones such as Levaquin, Cefaclor provides a solid option with fewer concerns about tendon damage or cartilage effects. Dosing varies by age and kidney function; adults typically take 250‑500 mg every 8 hours, whereas children receive weight‑based doses that ensure effective blood levels without excess risk.
Safety-wise, the drug is generally well‑tolerated, but side effects like diarrhea, nausea, or rash can appear. A crucial point is cross‑reactivity: about 5‑10 % of patients with penicillin allergy may also react to cephalosporins, so clinicians ask about past reactions before prescribing. Renal impairment calls for dose reduction because the drug is cleared unchanged by the kidneys; failing to adjust can raise serum levels and increase adverse events. Interactions are modest, though antacids containing aluminum or magnesium can lower absorption, and certain blood thinners may need closer monitoring. Understanding these nuances equips you to use Cefaclor confidently and avoid common pitfalls.
