I accidently somehow took 2 5/325mg norco. then i guess i forgot that i took them already and took 2 more. that was 1.5 hours ago, will i die?

Must be careful: Accidental overdose with Norco is one big reason why people are getting hurt and dying. If you are feeling tired, lethargic, shortness of breath, sleepy or other symptoms go to the ER. Most likely you will not be harmed this time, but you must be very very careful with these pain medications. Follow only your doctors regime, don't share meds, don't drink, and use the least amount necessary.
