Dramamine (Dimenhydrinate) – Patient Information (Australia)

Dramamine is a medicine containing dimenhydrinate. It is commonly used to help prevent and treat symptoms of motion sickness, such as nausea, vomiting, dizziness, and vertigo. This page explains how it works, how to take it, and key safety information for use in Australia.

Always read the packaging and consumer medicine information (CMI) that come with your product, as strengths and directions may vary between brands and formulations.

Quick overview

• Active ingredient: Dimenhydrinate
• Common uses: Motion sickness (prevention and relief), nausea and dizziness associated with travel
• Typical form: Oral tablets (and in some markets other forms may exist)
• How it works: Antihistamine that helps reduce motion-sickness signals to the brain
• Onset: Often within about 30–60 minutes (for prevention, take before travel)
• Common side effects: Drowsiness, dry mouth, constipation, blurred vision

What is Dramamine?

Dramamine is an over-the-counter medicine in many settings in Australia. It contains dimenhydrinate, a first-generation antihistamine. It is used to manage symptoms that can occur during car, bus, boat, or plane travel, and in some people it can also help with nausea and dizziness.

Dimenhydrinate belongs to the class of antihistamines (H1 antagonists). Because it affects the brain, it can help reduce nausea and feelings of dizziness—but it can also cause sleepiness.

Indications (what it’s used for)

In Australia, Dramamine is typically used for:

• Prevention of motion sickness (e.g., travel-related nausea, dizziness, vomiting)
• Treatment of motion-sickness symptoms that occur during travel
• Relief of nausea and dizziness related to motion (as directed by the product’s CMI)

If your symptoms are severe, unusual, or not clearly related to motion, consult a healthcare professional. Conditions such as migraine, inner ear disease, infections, or medication side effects may have similar symptoms.

How Dramamine works (mechanism of action)

Motion sickness is thought to involve conflicting signals between the visual system, the inner ear (vestibular system), and body movement. These signals are processed in brain areas that control nausea and balance.

Dimenhydrinate helps by acting mainly as an H1 antihistamine. It has anticholinergic effects and may also dampen signals in the central nervous system that contribute to nausea and dizziness. The combined effect helps reduce the body’s motion-sickness response.

Pharmacokinetics (what the body does to the medicine)

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates a medicine. While exact values can vary between individuals, the general pattern for dimenhydrinate is:

• Absorption: After oral dosing, dimenhydrinate is absorbed from the gastrointestinal tract.
• Distribution: Because it acts on the brain, it crosses into the central nervous system.
• Metabolism: It is metabolised in the liver.
• Elimination: Metabolites are removed primarily via the kidneys (urine).

For practical purposes, the key takeaways are: it works best when taken before travel, and effects are typically felt for several hours, though exact duration varies.

Typical dosing and timing (general guidance)

Dosing must follow the product’s CMI or label directions. The information below provides general guidance about timing and common dosing patterns for motion sickness medicines; however, always check the exact strength and age-based instructions for your specific package.

When to take it

• Prevention: Take Dramamine about 30–60 minutes before starting travel.
• During travel: If you miss the dose, you may still take it when symptoms begin, but it may work more slowly.

How often

• Most products are taken as needed and repeated at intervals that match the product label (commonly every 4–6 hours, depending on the formulation and age group).
• Do not exceed the maximum daily dose listed on the packaging.

Dose by age

Age-based dosing can vary. Use the label directions for the correct dose for your age group. If you are unsure, ask a pharmacist.

Can you take it with food?

Food can affect how comfortable and predictable the experience is, though it does not usually “cancel” the medicine’s effectiveness.

• With food: Taking Dramamine with a small meal or snack may reduce stomach upset.
• Empty stomach: Some people find it can cause nausea or irritation if taken on an empty stomach.

For best prevention, keep to the recommended timing (often 30–60 minutes before travel). If you eat right before travel, you may still take it but allow time for onset based on the label.

Alcohol interactions

Avoid or minimise alcohol while taking dimenhydrinate, because the combination can increase drowsiness and impair reaction time. This may also increase risk if you need to drive or operate machinery.

• Increased sedation: Alcohol plus Dramamine may make you feel more sleepy than either alone.
• Safety risk: Avoid driving, cycling, or using hazardous equipment after taking the medicine.

Interactions with other medicines

Dimenhydrinate may interact with other medicines that cause drowsiness or affect breathing. It can also have additive anticholinergic effects with some drugs.

Tell a pharmacist if you take:

• Other medicines that cause drowsiness (for example, many sedating antihistamines, sleep medicines, some anxiety medicines)
• Opioid pain medicines (risk of increased sedation and respiratory depression)
• Some antidepressants or other medicines with anticholinergic properties
• Medicines used for Parkinson’s disease or bladder conditions that may also have anticholinergic effects
• Other antihistamines (avoid doubling up on products for allergies/colds)

This is not a complete list. Always check the label and the CMI for warnings and, if needed, seek advice from a pharmacist.

Safety profile and precautions

Common side effects

• Drowsiness or sedation
• Dry mouth
• Blurred vision
• Constipation
• Dizziness (in some people, paradoxically) or reduced alertness
• Headache (less commonly)

Less common but important risks

Antihistamines with anticholinergic effects can be problematic in certain conditions. Seek advice promptly if you experience worrying symptoms.

• Confusion or severe sleepiness (more likely in older adults)
• Urinary retention or difficulty urinating (especially in people with prostate enlargement)
• Glaucoma symptoms (eye pain, redness, blurred vision) if you have narrow-angle glaucoma
• Irregular heartbeat or palpitations (uncommon; seek medical advice)

Who should be cautious

Extra care is needed if you:

• Have glaucoma (particularly narrow-angle)
• Have difficulty urinating or an enlarged prostate
• Have chronic respiratory conditions (risk of increased breathing problems when sedating medicines are combined)
• Are older and prone to falls or confusion
• Have liver impairment (discuss with a pharmacist if relevant)

Driving and operating machinery

Dramamine can cause drowsiness. Avoid driving, cycling, or operating machinery until you know how it affects you. Take special care during night travel or when combined with alcohol or other sedatives.

Children and infants

Use only if the product is indicated for the child’s age and follow the CMI exactly. Drowsiness can be stronger in children, and dosing mistakes can be harmful.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, discuss with a healthcare professional or pharmacist before use to weigh potential benefits and risks. Always follow the product’s CMI for advice.

Practical use tips (how to get the best results)

• Take it before you travel: Prevention usually works better than waiting for symptoms to appear.
• Choose a comfortable position: Sit facing forward (if possible), and look at the horizon to help the brain settle.
• Stay hydrated: Sip water if you feel nauseated.
• Keep air moving: Fresh air or cool airflow can reduce nausea for some people.
• Avoid strong smells: Perfumes, food odours, and smoke may worsen symptoms.
• Limit caffeine and heavy meals before travel: Light meals are often easier on the stomach.
• Test ahead of time: If you haven’t used it before, take a dose when you are at home to see how drowsy it makes you.

Food interactions

There are no widely known “dangerous” food interactions with dimenhydrinate for motion sickness, but comfort and timing can matter:

• Heavy, greasy meals before travel may worsen nausea, even if the medicine helps.
• Small snacks can be more comfortable than a large meal.
• Timing matters more than food: aim for the recommended pre-travel interval.

Typical timing example

Here is a simple scenario to illustrate how people commonly use it for prevention:

• T minus 60 minutes: Take Dramamine if you are prone to motion sickness.
• T minus 30 minutes: Settle in, choose a forward-facing seat, and consider light hydration.
• During travel: Keep movements smooth; avoid reading if that triggers symptoms.
• Re-dosing: Only repeat at the interval stated on the label and do not exceed the maximum daily dose.

Alternative options for motion sickness (Australia)

Different people respond differently. If Dramamine doesn’t suit you (for example, due to sedation), there are alternative approaches. Options may include:

Non-medicine strategies

• Positioning: Sit in the front seat or over the wing on planes; face forward.
• Look at the horizon and limit reading/scrolling.
• Ginger: some people find it helpful for nausea.
• Pressure bands (acupressure): may help some individuals.
• Reduce odours and ensure ventilation.

Medication alternatives

• Other antihistamines used for motion sickness (availability and suitability vary)
• Antimuscarinic medicines (some are prescription medicines in Australia; pharmacist advice is essential)
• Combination approaches: some travel plans use non-drug methods alongside a medicine

If you want an alternative due to drowsiness, ask a pharmacist about options that match your situation and travel plans.
