Tetanus shots and supplements...

I am scheduled to get a tetanus and a menengitas shot in about 7 hours. Right now, I am on Novedex XT testosterone bosster/estrogen inhibitor, and I am also taking Stimerex ES which has ephedrine (I am only taking in 50 mg of ephedra a day). Is it safe for me to be getting my shots?

I'm 22, 190 lbs and my blood pressure is really good (at least the doc says so) if any of that matters in your guys' thoughts...please let me know soon!!!
