"You are not the only one," Jacobs wrote. "It caused me to have a major bleed and then a week later a small haematoma burst. Still recovering."
Karleen Edmonds also put the word out, asking if anyone else had had trouble trying to open the bottles.
Twitter user Christopher Meek shared how much he wanted to try the new product, if only he could lift the lid.
Lewis Road responded to Mau by admitting the bottles are tough to get in to and promised they are "sorting this ASAP" with new caps due out next week.
While Mau later tweeted that the bottle remained unopened and she "should have gone with the Bailey's instead", Lewis Road also promised to send out fresh bottles to the presenter and her Twitter friends Jacobs and Edmonds.
