The most widely used over-the-counter option for dizziness is meclizine (sold as Antivert or Bonine), an antihistamine that calms the inner ear’s balance signals. For motion sickness, dimenhydrinate (Dramamine) works similarly. But “what to take” depends entirely on why you’re dizzy, and in many cases, the best remedy isn’t a pill at all.
Why the Cause Matters
Dizziness is a symptom, not a diagnosis, and it shows up in dozens of conditions. Dehydration, low blood sugar, inner ear problems, anxiety, blood pressure drops, medication side effects, and even vitamin deficiencies can all make you feel dizzy. A spinning sensation (vertigo) usually points to an inner ear issue, while lightheadedness often involves blood pressure or blood sugar. Feeling unsteady or “off” for weeks at a time may be tied to anxiety or a chronic vestibular condition.
This matters because a medication that helps one type of dizziness can be useless or even counterproductive for another. Meclizine works well for a few days of acute vertigo but can actually slow your brain’s ability to recalibrate if used long-term. Drinking water and eating something salty will fix dehydration-related dizziness faster than any antihistamine.
Over-the-Counter Medications
Meclizine is the go-to OTC choice for vertigo and motion sickness. It works by decreasing excitability in the inner ear’s labyrinth and blocking signals along the pathways between your inner ear and brain. For motion sickness, the standard adult dose is 25 to 50 mg taken one hour before travel, with no more than one dose every 24 hours. For vertigo episodes, 25 to 100 mg per day in divided doses is typical, though it works best when limited to two or three days during an acute flare.
Dimenhydrinate (Dramamine) is another antihistamine option that reduces vestibular stimulation through its anticholinergic activity. It’s especially popular for motion sickness and tends to cause more drowsiness than meclizine. Both of these medications treat symptoms only. They suppress the signals that make you feel dizzy and nauseous, but they don’t fix the underlying problem.
Risks for Older Adults
If you’re over 65, meclizine carries extra risks. The American Geriatrics Society has placed it on the Beers list of medications to avoid in patients over 65 because of its strong anticholinergic properties. In older adults, whose bodies clear the drug more slowly, meclizine increases the risk of confusion, falls, fractures, dry mouth, constipation, and overall mortality. The sedative effects compound these dangers. If you’re in this age group and dealing with recurring dizziness, a non-medication approach is generally safer and more effective.
Prescription Options
For severe acute vertigo, doctors sometimes prescribe diazepam (Valium), a benzodiazepine that depresses the central nervous system and can quickly quiet intense spinning episodes. It’s meant for short-term use only, as it interferes with the brain’s natural process of recalibrating to the inner ear problem, and it carries risks of dependence.
A different situation arises with persistent postural-perceptual dizziness (PPPD), a chronic condition where dizziness lingers for months, often triggered or worsened by anxiety. For PPPD, certain antidepressants in the SSRI and SNRI classes can reduce dizziness while also addressing the mental health issues that commonly accompany it. These medications take weeks to reach full effect and require ongoing management.
When a Physical Maneuver Works Better Than Medication
The most common cause of vertigo is benign paroxysmal positional vertigo (BPPV), where tiny calcium crystals drift into the wrong part of your inner ear canal. Turning your head certain ways dislodges them and triggers brief but intense spinning. For BPPV, the Epley maneuver, a series of specific head and body positions performed over about five minutes, is dramatically more effective than medication.
In a controlled study comparing the Epley maneuver to a common prescription vertigo drug, the maneuver resolved vertigo in 93% of patients compared to 63% for the medication group. Both approaches helped equally with the nausea and vomiting that often accompany vertigo, but for the spinning itself, the physical maneuver was clearly superior. A doctor or physical therapist can perform it in the office, and many people learn to do a version at home for future episodes.
Ginger and Natural Remedies
Ginger root has modest evidence behind it. In a controlled clinical study, ginger root reduced induced vertigo significantly better than placebo. It didn’t change the underlying eye movement patterns associated with vertigo, suggesting it works more on the sensation and nausea than on the vestibular system itself. Fresh ginger tea, ginger capsules, or even ginger chews may take the edge off mild dizziness, particularly the nausea component, without the sedation risks of antihistamines.
Staying well hydrated, avoiding sudden position changes (especially when standing up), and eating regular meals are basic but genuinely effective strategies for the most common causes of lightheadedness. If your dizziness hits when you stand up, try clenching your leg muscles for a few seconds before rising, and get up in stages rather than all at once.
Vitamin D and Recurring Vertigo
A growing body of research links low vitamin D levels to a higher incidence of BPPV. A meta-analysis published in BMJ Open found a negative correlation between vitamin D levels and BPPV occurrence, meaning people with lower vitamin D were more likely to develop it. Supplementing vitamin D in BPPV patients who were deficient has been shown to prolong symptom improvement and reduce the number of recurring episodes. If you’re getting frequent bouts of positional vertigo, checking your vitamin D level is a reasonable step.
When Dizziness Needs Urgent Attention
Most dizziness is benign, but it can occasionally signal a stroke, particularly when it comes on suddenly and is accompanied by other neurological symptoms. The combination of new vertigo with double vision, slurred speech, difficulty swallowing, severe imbalance where you can’t stand, or weakness or numbness on one side of the body warrants emergency evaluation. Trained clinicians can use specific bedside eye movement tests to distinguish an inner ear problem from a stroke, but these exams require expertise and shouldn’t be self-assessed. Sudden, severe dizziness that feels fundamentally different from anything you’ve experienced before, especially with any of those accompanying symptoms, is worth an emergency room visit.
