Amoxicillin-clavulanate and cefaclor are active ingredients used in some antibacterial drugs such as Augmentin and Cefaclor Oral Suspension to treat symptoms related to pneumonia, otitis media (middle ear infection), and sinusitis. These medications must be prescribed by a physician to treat your bacterial infection. Amoxicillin-clavulanate and cefaclor are very similar ingredients. However, your doctor may suggest one over the other depending on your medical condition and history. We’re here to compare both ingredients to help you determine which medication will work best for you.
Characteristics of Amoxicillin-clavulanate
Amoxicillin-clavulanate is found in some antibacterial drugs such as Augmentin. The ingredient helps treat bacterial infections, most commonly ear, nose, and throat infections. It is usually the first line of treatment for infections in children because it is effective in treating most childhood infections and has very little severe side effects.
Amoxicillin-clavulanate is also recommended for patients with infections that are harder to treat without antibiotics. In a study comparing the effectiveness of amoxicillin-clavulanate, researchers found that the drug was more effective in curing acute paranasal sinus infections than a placebo drug. However, the same study found that 43% of people with sinusitis were cured without antibacterial drugs. This means that drugs are not always necessary when treating certain conditions.
While Amoxicillin-clavulanate is known to have less severe side effects, there are some that may cause discomfort. These side effects include:
• diarrhea
• nausea
• vomiting
• yeast infections
• rash
If you experience these side effects after taking amoxicillin-clavulanate, consult with your physician. It’s also important to disclose all medical conditions with your doctor, especially allergies. Amoxicillin-clavulanate is derived from penicillin so patients with a penicillin allergy must avoid this drug.
Characteristics of Cefaclor
Cefaclor is an antibiotic that works by stopping the growth of bacteria. It is frequently used against bacteria responsible for causing skin infections, otitis media, and urinary tract infections. It is also helpful in treating pneumonia.
Cefaclor, found in Cefaclor Oral Suspension, is effective in treating infections but is prescribed less than amoxicillin based drugs. In a randomized controlled trial of amoxicillin and cefaclor, it was concluded that less effective than amoxicillin-clavulanate in treating acute otitis media. Another study advised that cefaclor should not replace amoxicillin as the first line of treatment. However, in some cases, it may be necessary to bypass amoxicillin.
Cefaclor is still a widely used drug, but it also has some side effects including:
• upset stomach
• headache
• nausea
• vomiting
• diarrhea
In rare cases, cefaclor may also cause some patients to develop hypersensitivity. Also, like many antibiotics, it’s possible for bacteria to become resistant to the drug. Consult with your doctor about the length of time you should be taking cefaclor.
Which Active Ingredient Is Right For Me?
While many studies suggest amoxicillin as the first line of treatment for bacterial infections, amoxicillin-clavulanate and cefaclor may both be effective. There are advantages and disadvantages of the ingredients, so you should discuss your options with your physician.
