What you can take for dizziness depends on what’s causing it. For general dizziness and vertigo, over-the-counter antihistamines like meclizine (sold as Bonine or Antivert) and dimenhydrinate (Dramamine) are the most widely used options. But medication isn’t always the best first step. The most common type of vertigo responds better to a simple head maneuver than to any pill, and dizziness from dehydration or low blood pressure resolves faster with fluids and electrolytes than with a drug.
Over-the-Counter Antihistamines
Meclizine and dimenhydrinate are the two main OTC medications that target dizziness directly. Both work by dampening the vestibular system, the balance-sensing network in your inner ear. Meclizine comes in 25 mg tablets and tends to cause less drowsiness than dimenhydrinate, which comes in 50 mg tablets. Both can make you sleepy, dry out your mouth, and blur your vision, but meclizine is generally easier to tolerate for daytime use.
These medications are useful for short-term relief of spinning sensations, motion sickness, and the nausea that often accompanies vertigo. They’re not designed for long-term use. In adults over 65, the American Geriatrics Society recommends against routine use of vestibular suppressants because they can increase fall risk. In studies of older adults with dizziness, both anti-nausea medications (including meclizine) and anti-anxiety drugs were associated with a higher rate of falls requiring medical attention.
When a Head Maneuver Works Better Than Medicine
The single most common cause of vertigo is benign paroxysmal positional vertigo, or BPPV. It happens when tiny calcium crystals in your inner ear drift into the wrong canal, triggering intense spinning when you move your head certain ways, like rolling over in bed or looking up. About 80% of BPPV cases involve the posterior semicircular canal.
For this type of dizziness, a physical maneuver called the Epley maneuver is far more effective than medication. In one clinical trial, the Epley maneuver resolved vertigo in 93% of patients compared to 63% of those treated with medication alone. Recurrence was also lower: only 10% of patients treated with the maneuver had vertigo come back, versus 30% in the medication group. A doctor or physical therapist can walk you through the maneuver, and many people learn to do a version of it at home.
Vitamin D may also play a role if you have recurring BPPV. A randomized controlled trial published in Neurology found that patients with low vitamin D who supplemented with vitamin D and calcium saw a 24% reduction in BPPV recurrence. Those with the most severe deficiency (levels below 10 ng/mL) saw a 45% drop. If you’ve had BPPV more than once, it’s worth asking about a vitamin D blood test.
Dizziness From Dehydration or Low Blood Pressure
If your dizziness hits when you stand up quickly, or after exercise, illness, or not drinking enough water, the problem is likely related to blood pressure or fluid balance rather than your inner ear. No amount of meclizine will fix this. What your body needs is fluids and electrolytes, specifically sodium, potassium, and magnesium. Sodium controls fluid levels in your body, potassium supports heart and nerve function, and magnesium aids nerve and muscle signaling.
Oral rehydration solutions (available at any drugstore) work faster than plain water because they contain a precise balance of salt and sugar that helps your body absorb fluid more efficiently. Sports drinks work in a pinch but contain more sugar than necessary. If you’re prone to lightheadedness when standing, increasing your daily water and salt intake can make a noticeable difference.
Ginger for Motion-Related Dizziness
Ginger has genuine evidence behind it for motion sickness and the nausea that comes with dizziness. Research published in the American Journal of Physiology found that pretreatment with 1,000 to 2,000 mg of ginger root reduced nausea and the stomach rhythm disruptions caused by motion. That’s roughly a half-teaspoon to a full teaspoon of powdered ginger, or two to four standard ginger capsules. It won’t stop a room from spinning, but it can take the edge off nausea without the drowsiness of antihistamines.
Prescription Options for Chronic Dizziness
When dizziness keeps coming back, the treatment shifts toward addressing the underlying cause rather than suppressing symptoms.
Vestibular Migraine
Vestibular migraine causes recurring episodes of dizziness that may or may not come with headache. Preventive treatments include blood pressure medications like propranolol, calcium channel blockers, anti-seizure medications, and certain antidepressants. These are taken daily to reduce how often episodes happen. Newer injectable medications originally developed for migraine prevention are also being studied for this condition. Finding the right preventive medication often takes some trial and error with your doctor.
Ménière’s Disease
Ménière’s disease causes episodes of vertigo along with hearing loss, ringing in the ears, and a feeling of fullness in the ear. Treatment typically involves medications that reduce fluid buildup in the inner ear. A low-sodium diet is commonly recommended, though a randomized controlled trial of 97 patients found that salt restriction alone did not improve the number or severity of vertigo episodes, hearing, or tinnitus scores compared to medication. Betahistine, a prescription medication that increases blood flow in the inner ear, showed benefit in the same trial.
Scopolamine Patches
Scopolamine is available as a patch placed behind the ear, primarily for motion sickness and nausea. It’s available both OTC and by prescription depending on the formulation. The patch releases medication slowly over several days. Side effects are common and can include blurred vision, dry mouth, confusion, and drowsiness. It’s not a great option for everyday dizziness, but it can be useful for predictable triggers like boat travel.
Dizziness That Needs Urgent Attention
Most dizziness is harmless, but it can occasionally signal a stroke, particularly in the back of the brain. This is true even when the only symptom is vertigo with no arm weakness or facial drooping. Research in the journal Stroke found that fewer than 20% of stroke patients who present with dizziness have the classic focal neurological signs most people associate with stroke, and standard stroke screening scales can score a zero even during an active posterior circulation stroke.
Isolated vertigo is actually the most common warning symptom before a stroke in the vertebrobasilar system, and it’s rarely identified correctly at first contact. Young patients are especially vulnerable to misdiagnosis: those aged 18 to 44 with stroke are seven times more likely to be misdiagnosed than patients over 75, partly because clinicians assume younger patients are having migraines.
Seek emergency care if your dizziness is sudden and severe, comes with double vision, difficulty speaking, trouble swallowing, new hearing loss, or intense head or neck pain. A sudden severe headache with vertigo can indicate an aneurysm or arterial tear. The combination of vertigo with any of these additional symptoms changes the situation from “what can I take” to “get evaluated now.”
