What is Cefaclor?

Cefaclor is an antibiotic medication used to treat bacterial infections. It belongs to the antibiotic class of cephalosporins, which also includes medications such as cephalexin and cefadroxil.

Cefaclor is available as a capsule, liquid suspension, and extended-release tablet. Its brand name is Ceclor. 

Cefaclor is considered a broad-spectrum antibiotic, meaning it is able to treat a wide range of bacterial infections. This can make it an appealing treatment option when an illness can have multiple potential bacterial causes or if a doctor suspects more than one strain is causing your condition. 

How Does Cefaclor Work?

Cefaclor works by impairing the bonds holding the bacterial cell wall together. The cell wall is the outside membrane of the bacteria, which maintains pressure within the bacteria’s cell. Cefaclor causes holes to appear in the cell walls, and as the holes build up, the pressure inside the cell builds until the membrane bursts, killing the bacteria. 

What Is Cefaclor Used For?

Cefaclor is used to treat many bacterial infections, some of which include:

• skin infections
• bladder infections
• ear infections
• respiratory tract infections
• tonsillitis
• pneumonia
• cystitis
• pyelonephritis
• bronchitis

This list is incomplete, and cefaclor may be prescribed to treat infections not included. 

Side Effects of Cefaclor

Common side effects of cefaclor include diarrhea and vaginal itching or discharge. 

There are also some serious side effects of cefaclor, which include:

• fever
• joint pain
• swollen glands
• severe stomach pain
• bloody or water diarrhea
• jaundice
• seizures

If you experience any of these side effects, contact a medical professional. 

Some people who take cefaclor may experience an allergic reaction, which has symptoms that can include numbness or tingling, hives, feeling light-headed, weakness, swelling of the lips, face, throat, or tongue, and difficulty breathing. If you exhibit any of these symptoms while taking cefaclor, seek immediate medical attention. 

Cefaclor is not recommended for anyone allergic to it or similar antibiotics, such as cefprozil (Cefzil), cefdinir (Omnicef), cephalexin (Keflex), and cefuroxime (Ceftin), among others. Also, inform your doctor if you have an allergy to penicillin, a stomach or intestinal disorder, or kidney disease before taking cefaclor. 

How To Take Cefaclor?

When taking any prescription medication, it is essential to follow all instructions provided by your doctor, including the dosage and dosing schedule. You should also continue taking cefaclor for the complete duration, even if you begin to feel better. Discontinuing cefaclor too soon increases the risk of a repeat infection or an even more severe illness. 

The dosage of cefaclor prescribed by your doctor will depend on many factors, such as your age, the type and severity of your condition, and what other medical conditions you have. 

Cefaclor can be taken with or without food. If you experience an upset stomach while taking cefaclor, taking it with food, or within 30 minutes of eating, may help ease these symptoms.  

For those taking the extended-release tablet, do not crush, break, or chew it—swallow the tablet whole. Those taking the capsule can open it, but if you do so, you must mix the contents with a liquid or applesauce and take the mixture right away. 

The tablets and capsules should be stored at room temperature and away from heat and moisture. As for the liquid suspension, store it in the refrigerator and dispose of any medication that has not been used within 14 days. 

If you miss a dose of cefaclor, take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed dose. Do not take two doses at once to make up for a missed dose as it is possible to overdose on cefaclor, with symptoms that include vomiting, nausea, diarrhea, and stomach pain. If you think you have overdosed, contact your doctor.
