Why did the tablet not work?
Almost always because it was taken too late. Motion sickness slows the stomach, so a tablet swallowed once you feel sick is barely absorbed — and not at all if you are vomiting.
Take it 30 minutes before you set off, or several hours ahead for a patch.
What works best?
Hyoscine hydrobromide, as a tablet for short journeys or a patch for longer ones. It is the most effective single option.
It is not suitable for everyone — glaucoma, prostate enlargement and older age all count against it.
Can my child take it?
Age limits differ between preparations, and several adult products are not suitable for young children.
Check before you buy rather than halving an adult dose — that is not how these are dosed.
Why am I fine driving but sick as a passenger?
Because the driver anticipates every movement, so the brain predicts what the balance organs are about to feel and the conflict never arises.
That is also why the front seat helps and the back seat does not.
Do the wristbands work?
Good-quality trials have not shown a benefit over placebo.
They are harmless, though, and if you find them helpful there is no reason to stop using them alongside everything else.
Does ginger help?
There is modest evidence, and it is harmless. Worth trying, particularly in pregnancy where the drug options are narrower.
It is not as effective as hyoscine for anyone who gets it badly.
Will I grow out of it?
Most children do. It peaks between about two and twelve and usually improves in the teenage years.
Adults who travel regularly habituate too — most people adapt within two or three days at sea.
Can I take an ordinary hay fever tablet instead?
No — non-sedating antihistamines do not work for motion sickness.
The ones that work are the sedating ones: cinnarizine, promethazine and cyclizine.
I still feel like I am swaying, days after the boat. Is that normal?
A day or two of land sickness is common and settles by itself.
Weeks of it is not motion sickness, and is worth having assessed properly.
Can I drive after taking it?
No. Hyoscine and the sedating antihistamines both impair driving, and hyoscine also blurs vision.
Plan for someone else to drive, and be careful with alcohol on the same day.
