Cefaclor: What It Is, How to Use It & What to Watch For

If you’ve been prescribed cefaclor, you probably wonder what this drug actually does. In simple terms, cefaclor is a second‑generation cephalosporin antibiotic. It fights bacteria by stopping them from building their cell walls, which kills the germs and helps your body heal.

How Cefaclor Works and What It Treats

Cefaclor targets a range of common infections. Doctors often use it for ear infections, throat infections like strep, sinusitis, bronchitis, and skin infections caused by susceptible bacteria. Because it’s a broader‑spectrum drug than first‑generation penicillins, it can handle bugs that are resistant to older antibiotics.

One thing to keep in mind: cefaclor only works on bacterial infections. It won’t help with viral colds or flu. If your doctor gave you this prescription, they’re confident a bacteria is behind your symptoms.

Dosage, Side Effects & Safety Tips

The usual adult dose is 250 mg to 1 g taken every 8 hours, depending on how severe the infection is. Kids get a weight‑based dose, so follow the doctor’s instructions carefully. Always finish the full course, even if you feel better early – stopping too soon can let bacteria survive and become resistant.

Side effects are generally mild. Expect possible stomach upset, diarrhea, or a rash. If you notice severe itching, swelling, difficulty breathing, or yellowing of your skin or eyes, seek medical help right away; these could be signs of an allergic reaction.

To reduce stomach issues, take cefaclor with food or a full glass of water. Avoid mixing it with antacids that contain aluminum or magnesium within two hours of the dose, as they can lower how much medicine your body absorbs.

Tell your doctor about any other meds you’re on – especially blood thinners, certain diuretics, or oral contraceptives – because cefaclor can interact and change how those drugs work. Pregnant or breastfeeding women should discuss risks with their healthcare provider before starting.

When you pick up the prescription, double‑check the label for the correct strength (250 mg vs 500 mg). Store tablets at room temperature away from moisture. If a dose is missed, take it as soon as you remember unless it’s almost time for your next one; then just skip the missed dose – don’t double up.

In summary, cefaclor is a reliable antibiotic for many common infections when used correctly. Stick to the prescribed schedule, watch for side effects, and keep an eye on possible drug interactions. If anything feels off, reach out to your doctor or pharmacist promptly.
