For uncomplicated UTIs, doctors commonly prescribe 250-500 mg of Keflex four times daily for 7-10 days. This dosage effectively combats most common UTI bacteria.
However, dosage adjustments depend on several factors. Severe infections might require higher doses, possibly up to 1 gram four times daily. Your physician will tailor the treatment to your specific needs based on factors such as the severity of the infection, your kidney function, and any allergies.
Always follow your doctor’s instructions precisely. Never alter the prescribed dosage or duration without consulting them. Taking less Keflex than prescribed might not completely clear the infection, leading to recurrence. Conversely, taking more than recommended increases the risk of side effects.
Common side effects include nausea, diarrhea, and stomach upset. Inform your doctor if you experience any adverse reactions. While generally well-tolerated, Keflex can interact with certain medications. Be sure to provide your doctor with a complete list of all medications you are currently taking, including over-the-counter drugs and supplements.
Remember, timely diagnosis and appropriate treatment are vital for UTI resolution. If symptoms persist or worsen, contact your doctor immediately.
