The court session has ended as the trial is moving into another courtroom to make space for the Supreme Court, which is sitting in Auckland tomorrow.

The five-judge higher court needs this big room that has been the scene of the Polkinghorne trial until now.

Courtroom 13, the trial's new home for the next week and a bit, is a lot smaller so the 70 or so people who have been coming each day will not fit in the public gallery.

Tomorrow, Hanna's GP, who has interim name suppression, will return to the witness box for more cross-examination.

The notes refer to long-term alcohol abuse.

Stuart suggests it is "incredibly concerning" that Hanna continued to receive anti-depressants while having an obvious drinking problem.

"Yes, on paper," the witness agrees. "In real life, if you knew Pauline Hanna, you wouldn't say that. It's a reality of life that it can go together."

"She was given medication to maintain normal mental health," says the witness.

Asthmatics use inhalers; Hanna was using the anti-depressants to manage her mood and depression.

The witness says the 11-year period she'd used Prozac for by that point was not uncommon.

Stuart asks why the drugs were being prescribed if the patient was not depressed.

The witness replies that ongoing use is normal if the person is functioning well. 

More Prozac and Duromine are prescribed in 2011. There's a record that year saying she's responding well to the Duromine.

In 2011, Hanna asked for a referral to a psychiatrist, the court hears, although there's no record of a referral letter.

"But it must have been done," the witness says.

"I don't know where it is."

More Prozac and Duromine are prescribed in 2012. 

The evidence now moves into 2010, when the witness was Hanna's doctor.

On July 22 of that year, Hanna had not seen the doctor for over a year and was advised to make an appointment.

On September 13, there was a request for a Prozac script.

"She's asking for medication she's been on for years," the witness says.

Was it chronic depression? asks Stuart.

We don't call it chronic depression, the witness says.

Hanna then asked for Duromine to replace Reductil, a weight-loss drug.

Stuart asks if that was because Reductil was found to be too high-risk. 

The doctor says she is not sure why it was withdrawn, or if it was because, as Stuart says, Medsafe deemed it unsafe.

Early in 2005 – also before the witness became Hanna's doctor – Hanna was prescribed another 180 capsules of Prozac, the court hears.

Then 180 more in August 2005 and in November. The records show she asked for more but was not happy to come in for a consult. 

Stuart returns to references that Hanna was experiencing relationship strife with Polkinghorne's children. 

She was prescribed an anti-depressant, Clonazepam, used to treat panic disorders, and Temazepam, a sleeping drug, which Stuart refers to as "quite a powerful cocktail of medications".

"It's not," says the GP, saying all the drugs are used for different things.

"You give different patients different medications on different occasions."

The GP offers that drugs are like children in a family, with one child being an engineer and another a doctor.

Hanna was later given an appetite suppressant, Reductil, a stimulant. Could this, Stuart asks, increase depressive thoughts?

The GP says many people who take it become happy, because they are achieving their weight-loss goals.

"It's similar to an amphetamine, is that right?" asks Stuart.

"In a way," replies the witness.

The witness agrees that 2004 was the first time Hanna was referred to any mental health support other than just being prescribed Prozac.

That Hanna was prescribed double the dose of Prozac was most likely as a result of a worsening of her symptoms, she agrees.

Stuart refers to another record showing Hanna had an alcohol dependence, and was prescribed Naltrexone to manage cravings and withdrawal symptoms.

These records, also from 2004, are from before the witness became involved in Hanna's care.

The witness wants to return to the earlier questioning about whether she referred Hanna to a psychiatrist, saying she was in fact referred in 2004.

"She was taken care of," the witness says.

Stuart asks about a note in the witness' records that said "not keen to come off".

Does that tell us there was a discussion about taking Hanna off Prozac? Stuart asks.

Possibly, says the witness.
