Cefaclor is a prescription antibiotic that is used to treat a variety of bacterial infections. This medication is designed to be taken by mouth and is available in the form of capsules, chewable tablets, and as a liquid suspension. It is important to use cefaclor exactly as prescribed by a doctor, and this drug should be taken in its entirety, even if symptoms begin to improve. Some of the most common side effects of this medication include joint pain, insomnia, and weight gain. More severe cefaclor side effects may include seizures, jaundice, or allergic reactions.
Respiratory infections such as bronchitis and pneumonia are often treated with cefaclor. Other infections, including those affecting the skin or urinary tract, may also be treated with this antibiotic. This medication is effective against infections caused by bacteria but is not designed to be used for viral or fungal infections.
Diarrhea is a common side effect of cefaclor, although this symptom is usually mild. Extra fluids should be consumed to avoid complications such as dehydration, especially if the diarrhea is severe or persistent. A doctor should be consulted before taking medications to treat this symptom due to possible medication interactions.
Joint pain and inflammation may occur when using this medication. Some patients may also experience symptoms such as appetite loss, insomnia, or dizziness. Women who take cefaclor may develop vaginal itching or abnormal discharge. Many of these side effects lessen or disappear as the body adjusts to the medication, although any bothersome symptoms should be reported to a doctor for further medical evaluation.
Serious complications associated with the use of cefaclor may occasionally develop and should be reported to a doctor right away. Seizures may occur spontaneously when taking this medication, even if the patient does not have a previous history of epilepsy or other seizure disorders. Jaundice, or a yellowing of the skin or eyes, may indicate liver damage. Severe abdominal pain, nausea, and vomiting may suggest damage to the digestive tract.
Allergic reactions are possible cefaclor side effects and may occur among those who have successfully taken this antibiotic in the past. Skin reactions often involve itching, rash, and blistering or peeling of the skin. A potentially fatal allergic reaction known as anaphylaxis may cause symptoms such as facial swelling, difficulty breathing, and loss of consciousness. It is important to obtain emergency medical assistance any time that an allergic reaction is suspected.
