Round Red Pill With Letter D On It

Hi. Ive been drinking alot recently and ive found a red tablet with D on oneside. I have no idea where its from or where i got it from please help. Thank you ## Hi Leanne, Are there any other markings on the pill you have besides a "D" ? The closest match I can find is Choledyl (100 mg); which is used in the treatment of asthma, maintenance and belongs to the drug class methylxanthines. It is a round red pill with the imprint PD 210. Maybe the other markings got rubbed off at some point? Manufacturer: Parke-Davis Learn More: Choledyl Details Please post back if you have any more questions so I can further assist you. ## Amitriptyline probably 50mg
