Hello, I Had A Paradontose Treatment Last Week In Germany

hello, I had a paradontose treatment last week in germany and forgot my chlorhexamed mouth wash. My dr told me I should ask for corcodyl. I was in the pharmacies of walgreens and publix. both told me they never heard of that product. can you recooend s.th. alternative without seeing a doctor? seeing adoctor would be 150$ thank you, Goetz
