How many 0.5g amoxicillin capsules should be taken at one time?

Under normal circumstances, adults should take one 0.5g capsule of amoxicillin each time, every 6 to 8 hours, with a maximum daily dose not exceeding 4g. If any abnormalities occur, medical advice should be sought promptly. Detailed information is as follows:

For adults and children weighing over 40kg, the usual dose is 0.5g (one capsule) every 6 to 8 hours, with a total daily dose not exceeding 4g. This dosage is suitable for most common infections, such as respiratory tract infections and urinary tract infections.

Dosage adjustments based on body weight are required for children and special populations. For children aged 3 months to 12 years, the dose is calculated at 20–40 mg/kg body weight, administered every 8 hours. For infants under 3 months, the dose is 30 mg/kg body weight, given every 12 hours. Dosage must be adjusted according to creatinine clearance in patients with renal impairment. Dose adjustment is generally unnecessary for mild to moderate hepatic impairment, but dose reduction is required in cases of severe hepatic dysfunction.

A negative penicillin skin test must be confirmed before administration; patients with known allergy should not use this medication. Alcohol consumption should be avoided during treatment to prevent adverse reactions. If symptoms such as rash or gastrointestinal discomfort occur, discontinue the drug immediately and seek medical attention.
