Dimenhydrinate is an antihistamine that belongs to the diphenhydramine class of medicines. Its main role is to relieve symptoms caused by motion-induced disturbances of the inner ear. In the United Kingdom, dimenhydrinate is found in products such as Dramamine and generic tablets labelled simply as Dimenhydrinate.
A range of over-the-counter tablets and liquid preparations include dimenhydrinate as the active ingredient. The most recognisable brand is Dramamine, available in tablet form and as a soluble powder that can be mixed with water. Generic versions are sold under the name Dimenhydrate and come in comparable strengths, typically 50 mg per tablet. These products are authorised by the UK Medicines and Healthcare products Regulatory Agency (MHRA) and can be bought in pharmacies, supermarkets and online retailers. Both brand-name and generic forms are offered in plain-pack and in sachets for children, though the exact packaging may differ between manufacturers.
Dimenhydrinate is most commonly used to manage the following conditions:
The ingredient works by reducing the activity of the inner-ear signals that trigger the brain’s nausea centre, helping the body adjust to movement that would otherwise cause discomfort.
When taken, dimenhydrinate blocks certain histamine receptors in the brain and inner ear. This action dampens the signals that the body interprets as motion, which can lessen the urge to vomit and ease the feeling of dizziness. Most people notice a reduction in symptoms within 30 minutes, and the effect can last for several hours, depending on the formulation.
These effects are usually short-lived and tend to lessen as the body becomes accustomed to the medication.
If any of these occur, seek immediate medical help.

Store dimenhydrinate tablets and liquids in a cool, dry place away from direct sunlight. Keep them out of reach of children. Treatment courses for motion sickness are usually short-term, but the exact duration should follow the guidance that comes with each product. Remember that each brand or generic version may have slightly different instructions, so always read the label that accompanies your specific medication.
