Getting hold of lateral flow tests may take longer than normal due to increased demand.
It comes as the Manx government introduces a raft of measures to mitigate the spread of COVID following the emergence of the omicron variant in the UK.
Tighter border restrictions and mandatory face coverings on public transport and in health care settings were announced on Sunday.
We're also being encouraged to test at least twice a week and before a night out.
A government spokesman said there's currently a very high demand for testing devices so if you have placed an order, you should allow more time for delivery.
