Can OTC Sudafed cause my urine drug screen to test positive for methamphetamines?

Hello. No, your test will show positive to the drug Pseudoephedrine, which is a key ingredient of the brand known as Sudafed. Pseudoephedrine is also the main ingredient to the making of methamphetamine. Allthough a perscription is not needed to purchase Sudafed, it is indeed kept behind the pharmacists counter and an identification must be shown when buying Sudafed. You might ask your doctor or pharmacist to confirm, or get thier opinion. Best of wishes and good health to you,pledge
