"Opthalmology referal"

Following a consultation the doctor advised that I should be taking additional drops to control the pressure in my eyes - he didn't advise if left or right were worse and I didn't ask.

I obtained the meds from the prescription he gave me and 3 days later I decided to stop them as I had very red, 'scratchy' eyes and a high degree of light sensitivity. I phoned several of the contact numbers on the back of the appointment letter and got no reply have left a message on one of them.

I eventually got through to the consultant's secretary who passed me on to a nurse. The nurse, having heard the events said she would email the consultant and ask for prescription that would not cause a reaction. She then asked if I wanted to collect the prescription or have mailed to me: I chose snail mail.

After 10 days the prescription had still not arrived but I picked up my repeat prescription from the pharmacy, Lloyds Longlevens, and found that an dditional eye drop had been added. I started taking that eye drop and the following day, 8/Jun, a prescription arrived in the post - it was different to the item on the repeat prescription.

I was confused as to which I should be taking! After contacting the pharmacy and the GP it turned out that I should be taking the meds delivered by snail mail.

Q1: how did my repeat prescription have a medication added that the GP did not know about?

Q2: why was the item added to my repeat prescription the same variety as the one I advised was causing me problems in the first instance?

Q3: why was a prescription sent in the post without a covering letter (just a compliments slip) and the GP did not know about the second change to my prescription?

Q4: why was there such a delay in making the change following my contact to say I had a reaction to the original meds on the 11/May?
