When should I take it before travelling?
Two hours before you set off. Taking it as you board is the commonest reason people say it did not work.
Will it make me drowsy?
Often, yes — less than older options, but enough to matter. Do not drive, and do not combine it with alcohol.
Can children take it?
From age 5, at half the adult dose. Below that, take advice.
Can I take it every day for dizziness?
Not for long periods, and particularly not over 65. Prolonged use can cause parkinsonism and low mood, and in vertigo it delays your recovery. Persistent dizziness needs a diagnosis.
What actually works for seasickness?
For a cruise, hyoscine patches are the most effective option. Alongside that: a midships cabin, fresh air, the horizon, and eating lightly rather than not at all.
Is it the same as an antihistamine for hay fever?
It is an antihistamine, but a sedating older-generation one that acts on the balance pathways. Fexofenadine or loratadine will do nothing for travel sickness.
