how many benadryl can you take in a day

For most adults, Benadryl is typically taken as 25–50 mg every 4–6 hours, with a common maximum of 300 mg in 24 hours. That usually means no more than 6 doses in a day, but the exact amount depends on the product and your age or health conditions.

Quick Scoop

• Adults and teens over 12: 25–50 mg every 4–6 hours as needed, not more than 300 mg in 24 hours.

• Some products differ: Always check the label, because liquid, regular strength, and extra-strength forms can have different directions.

• Be extra careful: Older adults and people with certain medical conditions may need a lower dose or should avoid it unless a clinician says it is okay.

Safety Notes

• Taking too much can cause confusion, dizziness, hallucinations, heart problems, or overdose symptoms.

• Do not combine it with alcohol or other sedating medicines unless a clinician has said it is safe.
