In some people side effects are more noticeable and melatonin is not suitable for all and it has become prescription only in the UK .
My partner had extreme low blood pressure one night after taking 10mg instead of 2 mg melatonin .He stood up walked fainted and fell became confused disorientated didn’t know where he was . I found him on all fours in the hall , he then tried to get up again felt immediately faint and fainted backwards through a doorway as he didn’t respond to me telling him to return to all fours .
Luckily uninjured I then persuaded him to crawl to bed .
He then needed the bathroom after 20 minutes couldn’t sit or kneel without feeling extremely faint as his blood pressure had lowered dramatically .
This lasted over an hour and only rectified when he slept it off with monitoring .
I feel the effects of melatonin and side effects are only just coming to light within the medical world .
We have a yellow card system for reporting side effects in the UK I’m definitely reporting this one .
Slight nausea and increased depression noted as well .
Side effects are listed as 1 in 100 or 1 in 1000 to cover melatonin but maybe they are more common .
My partner went to the doctor the next day and they were unaware of potential side effects and put it down to just getting out of bed .
The more people that flag side effects on medical reporting systems the more the medical world will build a picture of potential risks .
It may be a natural hormone but it can alter all sorts of physiology creating side effects .
