IN THE EVENT OF AN ERECTION LASTING OVER 4 CONTINUOUS HOURS, IMMEDIATE MEDICAL ATTENTION MUST BE OBTAINED
What to do if an erection lasts longer than 4 hours after contacting your physician:
Stop having sexual relations or masturbation.
Take 120 mg or 2x 60 mg of Sudafed (pseudopephrine), and wait 30 minutes. Please ignore this step if you have or are being treated for high blood pressure.
Take a warm bath or Jacuzzi for 40 minutes.
If the erection still has not subsided, take another 60 mg of Sudafed (pseudoephrine), and wait for another 30 minutes. Again, ignore this step if you have or are being treated for high blood pressure.
Make sure to rest and relax to let the erection subside. If after 3 hours, the erection will not relent, please contact your physician again. You can also speak with your physician about any OTC medication you may take if you have any discomfort.
