I have a massive headache (again ) that is making me feel really sick. So I took a maxalon and 2 panadol a few hours ago, all at once. Less than 5 minutes later, I vomited them and everything else in my stomach, back up.
Since then my headache has gotten steadily worse.

Can I take more or is the "dont re-take medications after vomiting" a blanket rule?
