To diagnose for seasonality in the volume of units sold the data has to come in quarterly lots going back for at least 5 years. I don't think these have ever been released - for some reason SRX prefers to trumpet growth rates which are not fit for our purpose because of the base effect.
Be that as it may, i took Peter Montgomery's quarterly growth data below (7Nov 2013) as approximates and plotting these show June quarters as being less variable than at other time of the year. Not sure if that means anything at all, to be honest. Also, it's relevant to ask why would dosage demand peak or trough at particular times of the year; like credit cards balances growing mostly over christmas or summer and being paid back throughout winter. In our case however there's just not enough info to go by.
