Everything you need to know about Cephalexin – an overview of over-the-counter antibiotics

General Description of Cephalexin

Cephalexin is a widely used antibiotic medication that belongs to the class of cephalosporins. It is commonly prescribed to treat various bacterial infections such as skin infections, urinary tract infections, respiratory tract infections, and ear infections.

As an antibiotic, cephalexin works by interfering with the bacteria’s cell wall formation, ultimately leading to their death. This medication is available in both oral capsule and liquid forms, making it convenient for patients of different age groups.

It is important to note that cephalexin is a prescription medication and should only be taken under the guidance of a healthcare professional. It is essential to complete the full course of treatment as prescribed by the doctor to ensure the infection is completely eradicated.

Cephalexin is generally well-tolerated by most individuals, but some common side effects may include diarrhea, nausea, vomiting, and allergic reactions. If any severe side effects occur, it is crucial to seek immediate medical attention.

Overall, cephalexin is an effective antibiotic that has been used for many years to treat a variety of bacterial infections. It is important to follow the prescribed dosage and duration of treatment to achieve the best results and avoid the development of antibiotic resistance.
