Yes, or at least it blocks effects if you take it pre-exposure. Risperidone, an atypical antispychotic, is also known for this. Some idiotic big pharma startup will try and milk this, rather than examining cheap existing medications. Plenty of medications block 5-HT2A, I think the important requirement here would be rapid absorption and high receptor occupancy.

Anecdotally, I've used risperidone specifically to abort LSD trips on two occasions and found it quite successful both times. Now when I introduce people to LSD I give them a Risperdal to keep in their pocket "just in case", though to my knowledge none of them have had to use it.

Simply knowing you have a backup strategy if you panic can go a long way to preventing panic attacks. Psychiatrists sometimes do something similar where they write a script for a benzo, just one or two for your bag.

Knowing you can control panic if it occurs goes such a ways in preventing panic at all.

Anecdotally, one of the best treatments for social anxiety I've found is to always know where the exits are. At a concert, identify the exit signs. In a conversation, have someone who can take over for you.

Knowing there's a way out of the situation can completely nullify the scariness of that situation.
