Daily How Much

For an 18-month-old, diphenhydramine should only be given when a pediatrician confirms the right weight-based dose for your child.

A typical 70 pound dog can often take about 70 mg of plain diphenhydramine per dose, but a veterinarian should confirm the exact amount first.

Small daily servings of beetroot juice or cooked beetroot may help lower blood pressure, but safe amounts depend on your health and medicines.

Most adults do well with a daily beetroot supplement that delivers about 300–500 mg of nitrate, adjusted to health status and product label.

Most adults do well with about ½–1 cup of cooked beets a day, or 1–2 small beets, as part of their regular vegetable intake.

Most healthy adults do well with about half to one cup of cooked beets or a small glass of beet juice each day as part of a varied diet.

Most adults see a modest drop in blood pressure with about 1 cup (140 g) cooked beets or 250–500 ml beetroot juice on most days.

A safe Benadryl dose for a cat comes from a veterinarian who matches the amount and timing to that cat’s weight, diagnosis, and health.

A common vet rule is 1 mg of diphenhydramine per pound of body weight, given every 8–12 hours, only after your veterinarian confirms the dose.

A 60 pound dog needs a Benadryl dose set by a veterinarian after checking health history, other drugs, and the reason for giving it.
