FDA Warnings

ALLOPURINOL

5 WARNINGS AND PRECAUTIONS Skin Rash and Hypersensitivity: Allopurinol has been associated with serious and sometimes fatal dermatological reactions
1 Skin Rash and Hypersensitivity Serious and sometimes fatal dermatologic reactions, including toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome (SJS), and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in patients taking allopurinol [see Adverse Reactions ( 6 )]
Other serious hypersensitivity reactions that have been reported include exfoliative, urticarial and purpuric lesions, generalized vasculitis, and irreversible hepatotoxicity
Patients who carry the HLA-B*58:01 allele are at a higher risk of allopurinol hypersensitivity syndrome (AHS), but hypersensitivity reactions have been reported in patients who do not carry this allele

PROBENECID

WARNINGS Exacerbation of gout following therapy with probenecid may occur; in such cases colchicine or other appropriate therapy is advisable
In patients on probenecid the use of salicylates in either small or large doses is contraindicated because it antagonizes the uricosuric action of probenecid

I was involved in an explosion a few years ago. I was burnt and whatnot and knocked around, but I don't think I ever lost consciousness from it. It was a pretty forceful explosion - it left a small crater in the concrete and knocked people over several metres away. The stuff I was holding in my hand
