What kind of med is a small round pill with 141 on one side?

You can ID your own pills by going to various pharmaceutical sites or even forums such as www.pharmer.org, www.drugs.com, www.rxlist.com or for serious searches you can check out http://www.nlm.nih.gov/services/drug_id.html. Obviously the easiest way is to search google, just type in 'pill' and any number identifiers.

Name: Hydromorphone 4 mg

Manufacturer: Mallinckrodt

Info: Hydromorphone, a more common synonym for dihydromorphinone and dimorphone, commonly a hydrochloride (trade names Palladone, Palladone SR, Dilaudid and numerous others) is a potent centrally-acting analgesic drug of the opioid class; it is a derivative of morphine, specifically a hydrogenated ketone thereof-therefore a semi-synthetic drug and both an opiate and a true narcotic. Hydromorphone is used in medicine as an alternative to morphine and diacetylmorphine for analgesia and as a second- or third-line narcotic antitussive (cough suppressant) for cases of dry, painful, paroxysmal coughing resulting from continuing bronchial irritation after influenza and other ailments, inhalation of fungus and other causes, and is generally regarded to be the strongest of the latter class of drugs, and was developed shortly after another powerful antitussive, heroin, was removed from clinical use for this purpose in most of the world and in many countries banned outright.
