When dreaded alien parasites are drilling into my head, I reach for Alambusol.
Alambusol is the only anti-parasite xeno-spray which I trust. Two squirts and ten minutes later, my head is clear and free of infestation once again.
[Cut to Medical office. Very modern.]
Yes, four out of our five doctors recommend Alambusol to their infested patients. The other doctor was fired. So, you can see that we are firmly committed to using this spray on our patients.

So transmit a bottle of Alambusol to yourself today! You won't be sorry.
