Pharmaceutical Use & Original Decision Criteria 
 
Dexamfetamine sulphate 5 mg tablets are indicated in the treatment of well-established and 
proven narcolepsy. It is also indicated for children with refractory hyperkinetic states under 
the supervision of a physician specialising in child psychiatry 
 
Background 
 
PSM/API advised 3/11/2015 that it would be OOS of dexamfetamine tabs if an export licence 
was not received urgently. At that time PSM/API had 4 weeks stock, and suggested limiting 
orders. 
 
PHARMAC staff contacted Medicines Control to expedite the licence and the licence was 
received by PSM/API on 10 November 2015. This allowed PSM/API to request manufacture 
and delivery of the active ingredient (dexamfetamine) which is expected to be received early 
December, and then manufacture/packaging and delivery of product would take up to 7 days. 
 
This means that there is a potential for there to be stock shortages for some patients in early 
December 2015 until expected resumption of supply week ending 20/12/2015 
 
 
PHARMAC staff will be following up around PSM/API’s application for licences to ensure that 
the situation does not arise again.

There appear to be limited alternative therapeutic options for patients. The main alternative 
option is methylphenidate, however our data indicate that 50%-60% of the patient group has 
already been prescribed methylphenidate and moved to dexamfetamine. We note that any 
move to a new medication would require a new Special Authority and/or new prescription 
and therefore a visit to prescriber. 
 
 
PHARMAC’s Management Plan   
 
Options 
Restrict sales from PSM  t/a API, and advise wholesalers of issue to 
limit orders; issue a letter to prescribers asking for Rxs to be amended 
to 15+15 till 1 Jan 2016. Note to pharmacists requesting dispensings 
be restricted. 
PSM/API are preparing a letter for the market for PHARMAC review to 
advise of supply issue.

tablets & nystatin oral liquid

THIS FAX CONTAINS TWO ISSUES FOR PHARMACY INFORMATION
1. Potential supply issue for dexamfetamine sulfate tabs 5 mg
There is currently limited supply of dexamfetamine sulfate 5 mg tablets (PSM).
There is no immediate risk of an out-of-stock situation with dexamfetamine sulfate 5 mg tablets, 
based  on  expected  usage.    However,  there  is  very  limited  supply  and  further  supplies  are  not 
expected until mid-December 2015. The stock issue is due to logistic arrangements, which have 
been resolved, but there may be a delay in resupply of stock. 
There may be instances where you need to dispense dexamfetamine sulfate 5 mg tablets 
in  less  than  the  prescribed  volumes.  This  alteration  would  need  to  be  endorsed  by  the 
prescriber.

We have written to prescribers who have a large number of patients on dexamfetamine to request 
they modify the dispensing period on their scripts, to dispense in 10 day lots as for other Class B 
controlled  drugs  (eg morphine).  As  a  Class  B1  controlled  drug  pharmacists  must  ensure 
dexamfetamine sulfate 5 mg tablets are dispensed as instructed by the prescriber in accordance 
with the relevant legislation.  
PHARMAC  is  working  closely  with  the  supplier, PSM  (trading  as  API), to  ensure  supply  is
maintained. PSM is managing the supply of dexamfetamine sulfate 5 mg tablets through limiting 
the quantities purchased through wholesalers. We recommend that  you contact PSM directly if 
you are unable to procure sufficient supply for your patient: NZ Freephone 0508 776 746
2. Change in price and subsidy for Aspen nystatin oral liquid 100,000 u per ml (Nilstat)

u per ml from 1 December 2015.  This price change will now not occur until 1 February 2016.

Dear  
 
Dexamfetamine sulfate 5 mg tablets (PSM) limited supply.  
 
We are aware you have prescribed dexamfetamine sulfate 5 mg tablets to at least XX patients in 
the last few months.  There is currently limited supply of dexamfetamine 5 mg tablets (supplied by 
PSM (trading as API)).  This is due to a delay in the arrival of the active ingredient into New 
Zealand for manufacture. 
 
We are working closely with PSM to ensure stock is manufactured as quickly as possible.  
To assist in managing the limited available stock we ask you to: 
•  please specify on any dexamfetamine prescriptions that it be dispensed in amounts of 10 
days supply, like you would for other Class B controlled drugs (ie morphine). 
  
This will help ensure that stock of dexamfetamine sulfate 5 mg tablets continues to be available 
until the new stock arrives, which is expected mid-December 2015. Pharmacists may contact you 
to confirm prescription changes if they need to dispense less than the prescribed quantity due to 
a stock shortage. 
The Misuse of Drugs legislation does not allow pharmacists to modify dispensing frequencies on 
controlled drug triplicate prescriptions, hence our request to you.   
If you have any questions regarding supply of dexamfetamine sulfate 5 mg tablets, please contact 
PSM’s customer services on: NZ Freephone 0508 776 746. 
Thank you for assisting us in managing this stock issue.  
Yours sincerely
