Not in pg BUT just a few weeks ago I had it. Its meant to last for months mine lasted for 1 wk as I pumped myself with immune building things AND the shingles medication. Which is completely safe while breastfeeding. Call the Royal womans hospitals drug line and they'll tell you if its safe while pg Honestly any drug issue while pg or breastfeeding call them or Rodney whyte...... Ill look for his number and post it if someone doesn't get here 1st

Good luck, shingles is dreadful
