Xanax, or Ativan.

such as Benadryl or Chlor-Trimeton.
- High blood
pressure medicines (antihypertensives), such as Inderal, Lopressor, verapamil,
Catapres, or reserpine.
- Diuretics, such as hydrochlorothiazide,
Diuril, Dyazide, Lasix, or spironolactone.
- Pain medicine,
such as codeine, Darvon, or Vicodin.
- Steroids, such
