Can I take Maxalt after Restylane fillers or will that have any negative effects on bruising/swelling/anything else?

Maxalt (the brand name for Rizatriptan) is a medication that is used to abort (or stop) Migraine headaches after they have started.  It increases the effect of Serotonin by acting like Serotonin.  The primary effect is to decrease the size of blood vessels, which can sometimes cause an increase in blood pressure.  However, this medication is not considered a blood thinner and does not increase bleeding.  Therefore, it is not a contraindication for use in a patient that is scheduled to have Botox injections.  It is important to note that the Botox treatment itself can also help to treat the headache, but it will take several days to take effect.   

There is no issue with taking a pain reliever after botulinum or filler injections.  Once it has been placed it should not rebleed.  Any bruising occurred at the time of injection.  Maxalt can raise your blood pressure some, but again should not be an issue.  Cool compresses and keeping your head elevated a few hours or the first night if you are concerned about swelling are helpful.  Hope you feel better and best regards.
