robitussin cough night

Nighttime Robitussin formulas commonly contain the cough suppressant dextromethorphan. Some options also include the antihistamine doxylamine and/or the expectorant guaifenesin.

Many nighttime products list an adult dose of 20 mL by mouth every six hours while symptoms persist. Product labels can vary, so always follow the specific label directions and do not exceed the recommended dose or interval.

Daytime formulations often combine a cough suppressant with an expectorant to loosen mucus and relieve chest congestion. Nighttime formulas typically pair a cough suppressant with an antihistamine to reduce runny nose and sneezing and help control coughing during sleep.

Many nighttime formulas are labeled for adults or for ages 12 and up. Children’s day/night packs provide dosing for ages 4 to under 6 and 6 to under 12 and list age exclusions for younger children—check the product label for exact age guidance.

Common options include single bottles (4 fl oz and 8 fl oz), 2‑pack combinations, and day/night combo packs.

Nighttime formulas target coughing and, when they include an antihistamine, relieve runny nose and sneezing to help control coughing during sleep. Daytime products in combo packs add an expectorant to help loosen chest congestion.

Daytime dosing: ages 4 to under 6 — 5 mL; ages 6 to under 12 — 10 mL; ages 12 and over — 20 mL every 4 hours (do not exceed 6 doses in 24 hours). Nighttime dosing: ages 6 to under 12 — 10 mL; ages 12 and over — 20 mL every 6 hours (do not exceed 4 nighttime doses). Children under the listed minimum ages should not use those formulas. Always follow the product label.

Children’s liquid bottles include a measuring/dosing cup. Labels instruct you to measure with the provided dosing cup and to keep the cup with the product.
