Excedrin PM Headache: what to know

The pain-relieving component may ease a mild headache, while the PM component is sedating and may make you sleepy. This combination can be unsuitable with alcohol, sleep medicines, sedatives, or other products containing the same ingredients. It may also need special advice if you have liver disease, glaucoma, difficulty urinating, or are pregnant or breastfeeding.

A headache can occur with a common cold, allergic rhinitis, sinus symptoms, dehydration, heat exhaustion, or an infection. The medicine may reduce pain without treating that underlying problem.

Read the active-ingredient panel and follow the package directions. Do not take extra doses because relief is slow, and avoid driving, operating machinery, or making safety-sensitive decisions if drowsy. Drink fluids when appropriate, rest, and note triggers, associated symptoms, and medicine use. A pharmacist can review the full list of products you take.

Seek emergency care for a sudden severe headache, confusion, weakness, trouble speaking, fainting, seizure, stiff neck with fever, serious breathing difficulty, or new vision loss. Seek prompt assessment for a persistent headache with high fever, dehydration, repeated vomiting, a recent head injury, or a pattern that is new or changing.

Ask whether the sedating ingredient is safe with your medicines and health conditions, how long you should self-treat, and what alternative plan fits recurring headaches.
