I have sometimes run into cases where I want to translate the name of a medication into Spanish, but can't find the specific medicine name in a dictionary (e.g. amoxicillin, acetaminophen). This is one area in language learning where you probably don't want to guess at what you think is the translation!
Are there any patterns for translating technical medicine names from English to Spanish? If not, are there any resources (printed or online) for finding the accurate translations of medications?
