Depends: What did you do with the Hydroxyzine tablet, If you did not swallow it. taking a second one will make you drowsy if the first one was absorbed. Were you trying to see if it absorbed by just placing it under the tongue? Please clarify. You must only place tablets under the tongue for absorption, if they are prescribed that way. Otherwise, you risk erratic and less absorption or sometimes, even more
