Amoxicillin suspensions and liquids offer convenient administration, particularly for children and individuals who struggle to swallow pills. Always check the medication label for the concentration – it’s usually expressed as milligrams of amoxicillin per milliliter (mg/mL) or per 5 mL (teaspoon). Accurate measurement is crucial for effective treatment.
Measuring Amoxicillin: Tools and Techniques
Use the measuring device included with the medication or a calibrated oral syringe for precise dosing. Household spoons are unreliable and can lead to inaccurate dosing. Always shake the suspension well before each dose to ensure even distribution of the amoxicillin.
Common Amoxicillin Liquid Concentrations
Concentrations vary. Common ones include 125 mg/5 mL, 250 mg/5 mL, and 400 mg/5 mL. Your doctor will prescribe the appropriate concentration and dosage based on your age, weight, and the infection’s severity. Never adjust the dosage on your own.
Storage and Shelf Life
| 125 mg/5mL | Yes | 7-10 days |
| 250 mg/5mL | Yes | 7-10 days |
| 400 mg/5mL | Yes | 7-10 days |
Always refrigerate reconstituted suspensions unless otherwise directed by the pharmacist. Discard any leftover medication after the expiration date printed on the label. Note that pre-mixed liquid amoxicillin may have a different shelf life than reconstituted suspensions.
Addressing Common Concerns
If your child refuses to take the medication, discuss alternative administration methods with your pediatrician or pharmacist. They may suggest flavoring it (always check if this is safe for the specific brand), or using a different administration method if available.
