|It might be a good idea to write all your allergies and any medications you take on a piece of paper and carry it in your wallet.
I did this on index cards for each member of my family (we have different allergies) this makes it easier when we are at a new doctor or a the ER.
I included allergies, current medication, history of operations,primary doctor with phone number, emergency contact and blood type.
I heard some EMT's can look in a person's wallet for such information. In an emergency I hope they'd look in mine.
