#[ diazepam and sertraline reportedly don't interact so he could have been dosed with diazepam to knock him out but at that point ]

While it was strongly claimed during Cosmic Turnabout that Clay caused Solomon's unconsciousness by overdosing him on his anxiety medication, this was not the case.

Solomon's PTSD would likely be treated with SSRIs, with the most likely prescriptions being venlafaxine, sertraline, or paroxetine. Of these three, only sertraline has an explicit side effect of potential loss of consciousness -- however, experiencing this side effect would be cause for hospitalisation and would not be conducive to space travel once Solomon was conscious. The only other alternative would be to cause serotonin syndrome by forcing Solomon's serotonin levels to spike beyond control, through either a medication overdose or combining his existing medication with other tablets to raise his serotonin.

However, serotonin syndrome would also run considerable risk of seizures and arrhythmia, which again would not be conducive to space travel and would be far too inexact as to how much of the medication to give Solomon without a) killing him b) causing him to be entirely unfit for space travel, rather than just knocked out for the launch and c) causing any of the other side effects of serotonin syndrome instead of unconsciousness in isolation.

This also does not tally with Simon explicitly stating that traces of medication were found in Solomon's system -- presuming Solomon had blood drawn shortly following Clay's attempted murder being discovered and police arriving, there is no feasible way that Solomon's unconsciousness could have been induced by his medication as the volume needed to cause the unconsciousness would show in far higher quantities in bloodwork than just "traces".

In truth, Clay assisted Yuri in 'managing' Solomon's anxiety with the launch by including generic sleeping tablets in his usual medication, passing them off as additional vitamins and assisting in this deception by taking visually similar actual vitamins himself. It was these tablets which caused Solomon's loss of consciousness for the HAT-2 launch; far safer than hamfistedly overdosing Solomon on his medication until he caused unconsciousness.

Clay worked under the assumption, with Yuri's deceitful confirmation, that the drugging was consensual and Solomon was aware of this potential plan, with Solomon being consensually unaware of the details as to avoid further anxiety. Following his recovery from the Phantom's attack, once he is medically cleared, Clay does stand trial for Solomon's spiking on charges of infliction of bodily harm.
