"Wrong medication given"

Was admitted into Combined assessment unit in August, 2022. Was taken in by ambulance, who had my own prescription with them and they passed this on to the doctor. Was kept in for 6 days, after having bad seizures, headache, loss of balance and blurred vision. During the 6 days I was given medication morning and evening. I questioned the medication every time I was given it. I knew it wasn't the medication I normally took, each time I questioned it, I was told that this was what the  doctor had prescribed. So thinking the doctor knows best, I took the medication.

On the day I was told I could come home, and still not feeling right, a member of staff came to me and told me that they were very sorry, they had to tell me I had been given the wrong medication throughout my stay. Next, another member of staff came  to see me from the hospital office, and also told me I had been given wrong medication, and that an investigation will be held. I came home that day with a list of the wrong medication. 

I have no problems with the nurses care I received, They were all lovely.

I have had no notification whatsoever about this investigation that is supposed to be being held. 

Yesterday, I phoned the hospital to try and speak to the person dealing with this. After being passed from pillar to post, trying to find out which office deals with this, I was told there isn't an office in the hospital that deals with this problem. So I am still none the wiser.

A suggestion for the future - when a patient questions their medication, maybe staff should double check. 

Had to go to my own GP recently. Still got symptoms mentioned above, they said this mistake should never ever have happened. 

I am very upset and unhappy that I had had wrong medication and wasn't listened to. 

I still don't know what is happening with the ongoing investigation.
