Now I do realize this would be a very small amount of blood, but I'm just curious. Yes, there are health risks associated with ingesting or being exposed to menses, because this is both fluid sharing and also blood sharing, even though menses is more than just blood.
Most over-the-counter sleep aids contain antihistamines. Tolerance to the sedative effects of antihistamines can develop quickly â so the longer you take them, the less likely they are to make you sleepy. In addition, some over-the-counter sleep aids can leave you feeling groggy and unwell the next day.
I've worked in a pharmacy for 7 years and NEVER heard anyone that couldn't take this. The last day or so, when I get dizzy/brain zaps, I have been taking meclizine (an antihistamine, like benadryl) during the day because it doesn't make me sleepy. It helps with the dizzinesss, brain zaps, and eye twitch type symptoms. It helps alot, but doesn't completely make it go away. At least I can handle it.
