Update:
I decided to simply leave some of my luggage and the Halatal at my Hotel in Lima, just to be safe.
Just out of curiosity i went to cusco and tried to buy in the known street.
Sad news tho:
I went to the known street (Tres Cruces De Oro) and asked in every shop that looked like it could possibly sell Halatal and these are the results:
- 1 shop needed a prescription
- 1 shop told me the doctor was currently away
- 1 shop only had halatal kt or halatal x
- 1 shop told me i should come back again tomorrow
- every single other shop didn't have it
Conclusion:
I was unsuccessful, seems like it got way harder in cusco to buy otc and nowadays it's easier in lima.
