IV vs. Oral Antibiotics: What's the Difference and Why It Matters

When it comes to treating infections, antibiotics are essential—but how they're delivered can make a big difference. At our urgent care clinic, we offer both oral and intravenous (IV) antibiotic treatments, depending on the severity and type of infection.

Benefits of IV Antibiotics

IV antibiotics are administered directly into the bloodstream, allowing them to work faster and more effectively in certain cases. This method is especially beneficial when:

• The infection is severe or rapidly progressing
• The patient is unable to tolerate oral medications (due to nausea, vomiting, or difficulty swallowing)
• There’s a need for high doses that can’t be achieved with pills alone
• The infection involves areas that are harder for oral antibiotics to reach, such as bones or deep tissues

Because they bypass the digestive system, IV antibiotics ensure immediate and full absorption, making them a preferred option when time and potency are critical.

IV antibiotics are generally used for bacterial infections in one of the following areas:

• lungs
• hearts
• bones
• soft tissue
• and/or brain

The primary classes of antibiotics are:

• Cephalosporins
• Fluoroquinolones
• Penicillins

Below is a list of some of the infections and bacterial diseases that we regularly treat with IV Antibiotics.

• Respiratory infections
• Bacterial skin infections
• Gastrointestinal infections
• Infections of wounds
• Post-operative infections

• Urinary Tract Infection
