List of Dangerous & Potentially Unsafe Combinations

[any major dude]

Here we'll try to keep a list of combinations of drugs that aren't safe to take in combination. This will be a work in progress & this list will not be exhaustive, so please still research things thoroughly before you ingest them!

Thanks to SurvivedAbortion for getting the ball rolling on this thread!

If your combination is not in the list, or you would like to ask about a specific combination or discuss potentially dangerous/risky combinations, or even make suggestions for this thread, please visit the Dangerous Combination Discussion Thread.

It would also be wise to check out the Medication & Supplement Interaction Thread for further information on medication reactions beyond simply stating whether a combination is dangerous or not.

If you see anything wrong in this list or something that needs to be added, please either post in the above thread, or PM one of the PD moderators and we'll get right on it.
