Dimenhydrinate is an antihistamine tablet sold in 50mg strength for motion sickness, nausea and vomiting, as plain Dimenhydrinate and as generic Dramamine, both ordered online.
Dimenhydrinate
50mg
Dimenhydrinate 50mg tablets are a travel-sickness medicine for motion sickness, nausea and vomiting, sold here in packs of 30 to 360 tablets.
Motion sickness comes from a disagreement between the eyes and the balance organs. The inner ear reports movement; if you are staring at a book or a phone, your eyes report that you are still, and the mismatch brings on dizziness, cold sweat, headache and queasiness. Dimenhydrinate is an antihistamine that quietens the signals travelling from the balance organ to the vomiting centre in the brain. It has two parts: diphenhydramine, which does the anti-nausea work, and 8-chlorotheophylline, added to take some of the edge off the sleepiness.
Fifty milligrams is the only strength sold here, and both products are tablets. Dimenhydrinate carries the ingredient's own name; Dramamine is the brand name the same medicine is widely known by. Same ingredient, same strength, same tablet form — what differs is the name and packaging, so the choice comes down to which pack you would rather have in your bag. Both sit in the shop's digestive health range, alongside other remedies for nausea and upset stomachs.
Most people take the tablet with a sip of water about half an hour before leaving, since it does far less once you already feel ill. Where you sit counts as well: the front of a car, the middle of a boat, eyes on the horizon, a window open. Books, phone screens and a big spicy breakfast all work against it.
Sleepiness is the one most people notice, and it can last a few hours. Dry mouth, blurred vision, dizziness and headache follow it on the list. Confusion or restlessness is uncommon and turns up more in older people. A rash with swelling or difficulty breathing needs urgent treatment. If you have glaucoma (raised pressure inside the eye) or find it hard to empty your bladder, either problem can get worse. A glovebox in summer is a poor home for the tablets, because heat and damp spoil them.
Travel is the best-known job, but the tablet is not limited to it. Because it calms the balance system, it is also used for vertigo, the spinning sensation that starts in the inner ear, and for nausea and vomiting with other causes. Occasional use suits it better than a daily habit: one crossing, a flight, a day of winding roads. The drowsiness matters for whoever is driving.
Dimenhydrinate can be ordered online with delivery to Hong Kong, listed as plain Dimenhydrinate tablets in 50mg and generic Dramamine tablets in the same 50mg strength. Tracked courier delivery takes 5 to 9 business days and comes with online tracking.
Prices vary between the two dimenhydrinate products and between pack sizes. Every product page lists its current prices in HKD or in the currency you choose.
PockDose does not ask you to upload a prescription when you order dimenhydrinate. See the ordering FAQ for details.
Dramamine is a brand name of dimenhydrinate, which is also sold as Driminate and Gravol. Here, dimenhydrinate can be bought online as generic Dramamine and dimenhydrinate tablets. These are generics, not the original brand.
It works for several hours — long enough for most ferry crossings, coach journeys and short flights — so a tablet taken before departure usually covers the trip. On a longer journey you can take a second tablet as the pack directs rather than taking two at once.
Alcohol makes the drowsiness and dizziness worse, and the combination can leave you unsteady on your feet. It also tends to bring on queasiness in its own right, so a drink before a journey works against the tablet. Leave the alcohol until you are back on solid ground.
It still helps, but it is much more effective before the queasiness starts. Once you are nauseated the tablet may come back up before it has been absorbed, and then it has no chance to work. Taking it before you leave is the reliable option.
Anything else that makes you drowsy adds to dimenhydrinate's effect: sleeping tablets, sedating painkillers such as codeine, and other antihistamines all stack with it, and the combination can be stronger than either medicine on its own.
