AB  - Overdose  with  these  agents  (clonidine,  guanabenz,  guanfacine,  methyldopa)  causes  bradycardia,  hypotension,  miosis,  respiratory  depression,  and  coma.  (Transient  hypertension  occasionally  occurs  after  acute  overdose,  a  result  of  peripheral  alpha-adrenergic  effects  in  high  doses.)  Symptoms  usually  resolve  in  less  than  24  hours,  and  deaths  are  rare.  Similar  symptoms  may  occur  after  ingestion  of  topical  nasal  decongestants  chemically  similar  to  clonidine  (oxymetazoline,  tetrahydrozoline,  naphazoline).  Brimonidine  and  apraclonidine  are  used  as  ophthalmic  preparations  for  glaucoma.  Tizanidine  is  a  centrally  acting  muscle  relaxant  structurally  related  to  clonidine;  it  produces  similar  toxicity  in  overdose.
