Cephalexin's broad-spectrum activity makes it a versatile antibiotic, suitable for treating a wide range of bacterial infections.

Commonly used for skin and soft tissue infections

Cephalexin is a frequently prescribed antibiotic for treating skin and soft tissue infections, which are commonly caused by bacteria that have invaded the skin or underlying tissues. These infections can range from minor to severe and may include:

• Impetigo: A contagious skin infection that typically starts as small blisters or sores that rupture and form a honey-colored crust.
• Cellulitis: A spreading infection of the deeper layers of the skin and underlying tissues, often caused by bacteria entering through a break in the skin.
• Abscesses: Localized collections of pus surrounded by inflamed tissue, which can occur anywhere in the body.
• Wound infections: Infections that develop in a wound, such as a surgical incision or a puncture wound.
• Folliculitis: Infection of the hair follicles, often caused by bacteria entering through shaving or other minor skin trauma.

Cephalexin's effectiveness against the bacteria that commonly cause these infections makes it a suitable choice for treatment. It works by inhibiting bacterial cell wall synthesis, preventing the bacteria from multiplying and spreading.

The duration of Cephalexin treatment for skin and soft tissue infections typically ranges from 7 to 10 days, depending on the severity of the infection. It is important to complete the full course of treatment as prescribed by your doctor, even if you start to feel better, to ensure that the infection is completely eradicated and prevent it from returning.

Cephalexin is generally well-tolerated, with common side effects including diarrhea, nausea, and vomiting. However, it is essential to inform your doctor about any allergies you have, especially to other antibiotics, before taking Cephalexin.

If you have a skin or soft tissue infection, your doctor may prescribe Cephalexin to combat the underlying bacterial infection and promote healing.

Also treats respiratory tract infections

Cephalexin is not only effective against skin and soft tissue infections but also commonly used to treat respiratory tract infections, which are infections of the organs and tissues involved in breathing. These infections can be caused by a variety of bacteria and may include:

• Pneumonia: An infection of the lungs, often caused by bacteria, viruses, or fungi. Symptoms may include cough, fever, shortness of breath, and chest pain.
• Bronchitis: Inflammation and infection of the bronchial tubes, the airways that carry air to and from the lungs. Symptoms may include cough, wheezing, and shortness of breath.
• Tonsillitis: Infection of the tonsils, two small masses of tissue at the back of the throat. Symptoms may include sore throat, difficulty swallowing, and fever.
• Sinusitis: Inflammation and infection of the sinuses, the air-filled cavities in the skull around the nose. Symptoms may include nasal congestion, facial pain and pressure, and fever.

Cephalexin's broad-spectrum activity makes it effective against the bacteria that commonly cause these respiratory tract infections. It works by inhibiting bacterial cell wall synthesis, preventing the bacteria from multiplying and spreading.

Can combat urinary tract infections

Cephalexin is also effective in treating urinary tract infections (UTIs), which are infections of the urinary system, including the bladder, urethra, ureters, and kidneys. UTIs can be caused by a variety of bacteria, including:

• Escherichia coli (E. coli): The most common cause of UTIs, E. coli is a type of bacteria that normally lives in the intestines but can cause infection when it enters the urinary tract.
• Klebsiella pneumoniae: Another type of bacteria that can cause UTIs, Klebsiella pneumoniae is also commonly found in the intestines and can cause infection if it enters the urinary tract.
• Proteus mirabilis: This type of bacteria is often found in the environment and can cause UTIs if it enters the urinary tract through the urethra.
• Staphylococcus saprophyticus: This type of bacteria is commonly found on the skin and can cause UTIs if it enters the urinary tract through the urethra.

Cephalexin's broad-spectrum activity makes it effective against these bacteria that commonly cause UTIs. It works by inhibiting bacterial cell wall synthesis, preventing the bacteria from multiplying and spreading. Cephalexin is commonly prescribed for 7 to 10 days to treat UTIs.

Dosage varies based on infection and individual

The dosage of Cephalexin prescribed will vary depending on several factors, including the type and severity of the infection, the age and weight of the individual, and their kidney function. Your doctor will determine the appropriate dosage for you based on these factors.
