Amoxicillin 500mg Dosage: How Many Days Should You Take It?
When prescribed amoxicillin 500mg, one of the most common questions patients have is: “How many days should I take this antibiotic?” The duration of your amoxicillin 500mg dosage depends on several factors, including the type of infection being treated, your medical history, and your doctor’s recommendation. In this comprehensive guide, we’ll explore standard treatment durations, factors affecting dosage length, and important safety considerations for this widely-used antibiotic.
Understanding Amoxicillin 500mg Dosage
Amoxicillin is a penicillin-type antibiotic that fights bacterial infections. The 500mg dosage is one of the most commonly prescribed strengths for adults. Proper dosage duration is crucial because taking antibiotics for too short a time may not fully eliminate the infection, while taking them too long can contribute to antibiotic resistance.
How Amoxicillin Works
Amoxicillin works by:
- Interfering with bacterial cell wall synthesis
- Causing bacteria to rupture and die
- Being effective against both Gram-positive and some Gram-negative bacteria
Standard Treatment Durations for Common Infections
The number of days for your amoxicillin 500mg dosage will vary based on your specific infection. Below are typical treatment durations:
1. Respiratory Tract Infections
- Acute otitis media (ear infection): 5-10 days
- Strep throat: 10 days
- Sinusitis: 5-14 days
- Bronchitis: 5-7 days (if bacterial)
2. Urinary Tract Infections
- Uncomplicated UTI: 3-7 days
- Complicated UTI: 7-14 days
3. Skin Infections
- Cellulitis: 7-14 days
- Impetigo: 7 days
4. Dental Infections
- Dental abscess: 5-7 days
- Periodontal infection: 7-10 days
Factors That Affect Amoxicillin 500mg Dosage Duration
Several variables can influence how many days you’ll need to take amoxicillin 500mg:
1. Type and Severity of Infection
More serious infections typically require longer treatment courses. For example, a simple ear infection might need 5 days, while pneumonia could require 7-14 days.
2. Patient Age and Weight
Children often receive weight-based dosing and may have different duration recommendations than adults.
3. Kidney Function
Patients with impaired kidney function may need adjusted dosages or durations.
4. Treatment Response
If symptoms persist, your doctor may extend the treatment period.

Frequently Asked Questions
Can I stop amoxicillin early if I feel better?
No. Always complete the full prescribed course to ensure the infection is completely eradicated and to prevent antibiotic resistance.
