What is the best medication for motion sickness? A Complete Guide

5 min read

According to the CDC, nearly all people will experience symptoms of motion sickness in response to severe motion stimuli. To combat the nausea and dizziness, many turn to medications, but determining what is the best medication for motion sickness depends on various factors, including the type of travel, desired duration of relief, and potential side effects.

Quick Summary

Motion sickness relief options range from highly effective, long-lasting prescription patches to popular, accessible over-the-counter antihistamines. The right choice depends on the specific travel conditions and an individual's sensitivity to side effects like drowsiness. Factors to consider include age, duration of travel, and other health conditions.

Key Points

  • Scopolamine for Long Journeys: For severe or prolonged motion, the prescription-only scopolamine patch is highly effective, offering up to 72 hours of relief.

  • Meclizine for Less Drowsiness: An OTC antihistamine offering 24-hour relief with less drowsiness than Original Dramamine, ideal for all-day coverage.

  • Dimenhydrinate for Quick Relief: Original Dramamine provides fast-acting relief for shorter trips but can cause significant drowsiness.

  • Prophylactic Use is Best: Motion sickness medication should be taken before symptoms begin for maximum effectiveness, as absorption is poor once nausea starts.

  • Combine with Behavioral Tactics: Non-drug methods like focusing on the horizon, getting fresh air, and managing meals can complement medication and reduce symptoms.

  • Not for Young Children: The scopolamine patch is not safe for children under 12 due to potential side effects; dimenhydrinate (Dramamine for Kids) is a safer OTC option for kids over 2.

  • Consult a Doctor for Severe Cases: If motion sickness is severe, persistent, or not responding to OTC options, a healthcare provider can discuss stronger treatments or rule out other issues.

Motion sickness occurs when there is a mismatch between the signals sent from the inner ear's balance system and what the eyes and body perceive. This sensory confusion can lead to hallmark symptoms such as nausea, vomiting, dizziness, and cold sweats. For many, preventive medication is the most effective way to avoid these unpleasant symptoms. When choosing a medication, key considerations include the length of your trip, the intensity of motion, potential side effects, and your age.

Over-the-Counter Medications

For many people, over-the-counter (OTC) options provide sufficient relief, especially for shorter trips. Most OTC motion sickness medications are first-generation antihistamines, which work by blocking signals in the brain associated with balance.

  • Dimenhydrinate (Original Dramamine): This is a widely available and popular OTC option. It is effective for preventing nausea and can be taken by adults and children over 2 years of age.
    • Usage: Needs to be taken 30 to 60 minutes before travel and is re-dosed every 4-6 hours.
    • Side Effects: A significant side effect is drowsiness, which may be more pronounced than with other options.
  • Meclizine (Bonine, Dramamine Less Drowsy): Meclizine is another OTC antihistamine that is generally considered less sedating than dimenhydrinate. Its long-acting formula offers a full 24 hours of relief, making it convenient for single-day use.
    • Usage: Take one hour before travel. Approved for adults and children 12 years and older.
    • Side Effects: Less drowsiness than Original Dramamine, but can still cause dry mouth and dizziness.
  • Diphenhydramine (Benadryl): While primarily an allergy medication, diphenhydramine also has anticholinergic effects that help with motion sickness.
    • Usage: Available in various forms and safe for children aged 2 and older.
    • Side Effects: Highly sedating and can cause paradoxical agitation in some children.

Prescription Medications

For longer, more severe motion exposure, such as cruises, a prescription medication may be the best choice. These tend to be more potent and offer longer-lasting relief.

  • Scopolamine (Transderm Scop): A highly effective anticholinergic medication that is often considered a first-line option for preventing motion sickness in adults. It is a convenient transdermal patch that provides continuous medication delivery over several days.
    • Usage: Apply one patch behind the ear at least 4 hours before travel. A single patch lasts up to 72 hours.
    • Side Effects: Can cause dry mouth, blurred vision, dizziness, and drowsiness. An FDA warning highlights the risk of hyperthermia, especially in children and the elderly. It is not recommended for children under 12.
  • Promethazine (Phenergan): A prescription-only antihistamine known for being very sedating. It is also available as a rectal suppository, which can be useful if vomiting has already started and oral medication is not feasible.
    • Usage: Requires a prescription and is available in tablets, liquid, and suppositories. Not for children under 2 years old.
    • Side Effects: Highly sedating, with common side effects including dry mouth and dizziness.

Comparison of Key Motion Sickness Medications

Medication Type Active Ingredient Onset Duration Target Age Common Side Effects Best For
Scopolamine Prescription Scopolamine 4+ hours Up to 72 hours Adults (12+) Dry mouth, blurred vision, drowsiness, hyperthermia risk Long-term trips (cruises) and severe motion
Dimenhydrinate Over-the-Counter Dimenhydrinate 30-60 minutes 4-8 hours Adults & children (2+) Drowsiness, dry mouth Shorter trips, fast-acting relief
Meclizine Over-the-Counter Meclizine 60 minutes 24 hours Adults & children (12+) Less drowsiness than dimenhydrinate, dry mouth, dizziness All-day coverage with less sedation
Promethazine Prescription Promethazine 30-60 minutes Up to 15 hours Adults & children (2+) Significant drowsiness, dry mouth, dizziness Intense motion, severe symptoms (highly sedating)

Natural Remedies and Behavioral Strategies

While medications are highly effective, non-pharmaceutical approaches can also help prevent or lessen motion sickness symptoms.

  • Ginger: Ginger root is a classic remedy for nausea. Some studies suggest it can help reduce motion sickness symptoms, though the evidence is mixed compared to medications. It can be consumed as capsules, chews, or in ginger ale.
  • Acupressure Wristbands: These bands apply pressure to the P6 acupressure point on the inner wrist. While some find them helpful, studies on their effectiveness are inconsistent.
  • Focus on the Horizon: A common and effective strategy is to look at a fixed point on the horizon. This helps synchronize the visual and vestibular systems and reduces sensory mismatch.
  • Optimal Seating: In a car, sitting in the front seat offers a better view of the horizon. On a plane, choosing a seat over the wing is best, and on a boat, staying near the center or water level helps minimize movement.
  • Fresh Air: Poor ventilation and strong odors can worsen symptoms. Opening a window or stepping outside for fresh air can provide relief.
  • Strategic Eating: Avoid heavy, greasy, or spicy meals before and during travel. Opt for small, bland snacks like crackers and stay hydrated with water.

Considerations for Special Populations

When treating motion sickness, specific groups require careful consideration and consultation with a healthcare professional.

  • Children: Dimenhydrinate (Dramamine for Kids) is a reliable OTC option for children aged 2 and older. Due to risks like confusion and hallucinations, scopolamine patches are not recommended for children under 12.
  • Pregnant Women: Pregnancy can increase susceptibility to motion sickness. Certain medications like meclizine and dimenhydrinate are generally considered safer during pregnancy (Category B), but always consult a doctor before use. Non-drug options like ginger are also popular.
  • Older Adults: Older adults can be more sensitive to the side effects of motion sickness medication, especially anticholinergics like scopolamine, which can cause increased drowsiness, dizziness, and vision problems. A less sedating option like meclizine may be preferable, but always use caution.

Conclusion

The most suitable medication for motion sickness is highly individualized and depends on the specific context of your travel. For shorter, less intense motion, OTC options like meclizine offer a good balance of effectiveness and minimal drowsiness. For prolonged, high-intensity trips like cruises, the convenience and potency of a prescription scopolamine patch are often the best choice, provided there are no contraindications. Always take motion sickness medication prophylactically—before you feel sick—for maximum effectiveness. Pairing medication with behavioral strategies, like focusing on the horizon and getting fresh air, can further enhance relief and help you enjoy your journey more comfortably.

If standard OTC remedies don't work or if symptoms are severe, consulting a healthcare provider is the safest path forward to find the right treatment plan.
