Should this be included in "Click here for everything you wanted to know about Ecstasy"

Someone could have Cyproheptadine in their posession if something doesn't seem right.

Antidote: Cyproheptadine — If benzodiazepines and supportive care fail to improve agitation and correct vital signs, we suggest antidotal therapy with cyproheptadine [16]. Cyproheptadine is a histamine-1 receptor antagonist with nonspecific 5-HT1A and 5-HT2A antagonistic properties [16]. It also has weak anticholinergic activity.

Cyproheptadine is available in 4 mg tablets or 2 mg/5 mL syrup [8]. When administered as an antidote for serotonin syndrome, an initial dose of 12 mg is recommended, followed by 2 mg every two hours until clinical response is seen. Cyproheptadine is only available in an oral form, but it may be crushed and given through a nasogastric or orogastric tube.

Cyproheptadine may lead to sedation, but this effect is consistent with the goals of management [1]. Furthermore, as a nonspecific serotonin antagonist, cyproheptadine may produce transient hypotension due to the reversal of serotonin-mediated increases in vascular tone. Such hypotension usually responds to intravenous fluids. Cyproheptadine is rated category B for safety in pregnancy by the US Food and Drug administration (FDA) (table 5) [8].

Definitive evidence of cyproheptadine's effectiveness is lacking. A small study used PET scan to assess 5-HT2 blockade in two volunteers after taking cyproheptadine (12 mg and 18 mg per day for six days). At 12 mg/day, there was 85 percent blockade and at 18 mg/day there was over 95 percent blockade of 5-HT2 receptors in the prefrontal cortex [17]. In addition, many reports describe the successful use of cyproheptadine to treat serotonin syndrome [16,18-23]. The majority of these patients received cyproheptadine at an initial dose of 8 mg, while fewer patients responded to as little as 4 mg and some had no response to as much as 16 mg.
 
I have also heard of ketanserin and it's relatives suggested as antidotes for SS. I'm surprised that this type of discussion is not more common, and that many hospitals are unaware of the benefits of 5-ht antagonists, especially with the rise of serotonergic agents, both illicit and prescription.
 
SS is a medical emergency. It seems as if we get a thread from a paranoid greenlighter who diagnosed themelves with SS once a week.

If someone suspects they have SS, the need to go to the ER, not take this on their own.
 
Yes it is a medical emergency and a person should go to the ER but it wouldn't hurt to have it on you if someone feels a little bit off.

Only have to read the "Don't shout at me BL" post to see what i'm talking about.
