Can I take amoxicillin with rice, or does eating rice reduce its effectiveness?

You can take amoxicillin with rice, and eating rice generally does not reduce its effectiveness. Official product information indicates that amoxicillin capsules, chewable tablets, and oral suspensions may be taken without regard to meals, and human studies show little or no difference in amoxicillin absorption whether taken fasting or with food. ^{[1] [2]}

Quick Answer

• Safe with meals: Amoxicillin can be taken with food, including rice. ^[1]
• Absorption is reliable: Clinical studies found little to no impact of food on amoxicillin levels in the blood. ^[2]
• When in doubt: Some specific tablet/suspension strengths have been studied at the start of a light meal, supporting meal-time dosing. ^[1]

What Official Guidance Says

• The approved labeling states that amoxicillin capsules, chewable tablets, and oral suspensions may be given without regard to meals, meaning they can be taken with or without food. ^[1] The same labeling notes that the 400 mg suspension, 400 mg chewable tablet, and 875 mg tablet were studied when given at the start of a light meal, which supports meal-time dosing as acceptable. ^[1]
• Food‑effect studies for some strengths (e.g., 200 mg and 500 mg tablets) have not been specifically performed, but the overall guidance remains that dosing does not need to be tied to fasting. ^[1]

Evidence From Human Studies

• In a crossover study of healthy adults given a single 500 mg dose, peak amoxicillin blood levels were essentially the same when taken fasting versus non‑fasting (8.9 vs 8.8 µg/mL), and overall exposure (AUC) and urinary recovery were similarly close, indicating reliable absorption with food. ^[2] These findings support practical use with meals, including carbohydrate‑rich foods like rice. ^[2]

Practical Tips for Taking Amoxicillin

• Take with a light meal if your stomach is sensitive. Amoxicillin can sometimes cause nausea; taking it with food like rice may help comfort without hurting absorption. ^[1]
• Stay consistent: Try to take doses at evenly spaced times each day for best effectiveness, with or without food, whichever is easier for you. ^[1]
• Hydration matters: Swallow capsules or tablets with a full glass of water to help dissolution and comfort. ^[3] If using chewable tablets, chew before swallowing as directed. ^[1]

Special Notes by Formulation

• Capsules/chewables/suspension: May be taken without regard to meals; meal-time dosing is acceptable and has been studied for certain strengths at the start of a light meal. ^[1]
• 875 mg tablet and 400 mg formulations: Specifically evaluated with a light meal, supporting that a meal like rice does not meaningfully reduce effectiveness. ^[1]

Common Concerns

• Does rice (carbohydrate) block absorption? Available evidence indicates amoxicillin’s absorption is stable with food, unlike some older penicillins (e.g., ampicillin) that show reduced absorption with meals. ^[2] Therefore, rice does not appear to reduce amoxicillin’s effectiveness when taken as part of a normal meal. ^[2]

Bottom Line

You can take amoxicillin with rice or other foods; its effectiveness is not meaningfully reduced by eating. This flexibility can help reduce stomach upset and improve adherence to your dosing schedule. ^{[1] [2]}
