Finasteride not making it through customs?

I'm wondering if anyone has been in this situation. If so, could they please help?

I ordered fincar from inhouse pharmacy to UK by parcelforce 24 delivery. They post from an island called Vanuatu in south pacific.

My tracking says it's awaiting customs clearance.

Do you think they'll let it through? Are you allowed to bring generic drugs into the UK?

If they don't, do i just lose my money or will inhouse pharmacy provide a refund?

I've ordered from United Pharamacies a couple of times and not had a problem. I think it comes from Asia somewhere.

Although I've also ordered toothpaste from the USA and had to pay customs duty.

Will be interesting to hear what happens.
