Hi & Welcome.
Hydromet may cause harmful effects if taken along with Tylenol PM.
1. Hydromet contains an
anticholinergic (Homatropine) & an opioid (
Hydrocodone) is used for the symptomatic relief of cough.
2.
Alka-Seltzer contains a pain reliever (Aspirin) and an antacid commonly used for the symptomatic relief of headache, body aches, heartburn, indigestion or stomach acidity.
3. Tylenol PM contains combination of a pain reliever and pain reducer (
Acetaminophen) & an antihistamine (
Diphenhydramine) used to treat headache, runny nose, sneezing, watery eyes, and pain or fever caused by allergies, the common cold, or the flu.
Taking Diphenhydramine (Tylenol PM) together with Hydrocodone (Hydromet) may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. It may also cause impairment in thinking, judgement, and motor coordination which may result in falls and injuries.
So, in view of the above avoid taking Hydromet along with Tylenol PM.
Hope these answer your queries.
