What you take for dizziness depends on what’s causing it. For most people, an over-the-counter antihistamine like meclizine is the first-line option, available at any pharmacy without a prescription. But dizziness has dozens of possible causes, from inner ear problems to dehydration to migraine, and the most effective treatment targets the underlying issue rather than just masking the spinning sensation.
Over-the-Counter Antihistamines
Meclizine (sold as Bonine or Dramamine Less Drowsy) is the most widely used OTC medication for dizziness and vertigo. For motion sickness, the standard dose is 25 to 50 mg taken one hour before travel, with no more than one dose every 24 hours. For vertigo from inner ear problems, doses range from 25 to 100 mg per day, split across multiple doses. The main side effect is drowsiness. Dry mouth, headache, and blurred vision can also occur.
Dimenhydrinate (original Dramamine) works similarly and is most effective when used for two to three days during active vertigo episodes. Both medications work by calming the inner ear’s signaling to the brain, which reduces the mismatch that creates the sensation of spinning or imbalance. These drugs are meant for short-term use. Taking them longer can actually slow your brain’s ability to adapt and recover from whatever is causing the dizziness in the first place.
Prescription Options for Severe Vertigo
When OTC antihistamines aren’t enough, doctors may prescribe stronger medications. Benzodiazepines like diazepam are effective for acute vertigo episodes because they enhance the brain’s natural calming signals, which quiets the overactive balance circuits. However, these are prescribed cautiously and discontinued as quickly as possible to allow the brain’s balance system to recalibrate on its own.
Anti-nausea medications like promethazine and prochlorperazine are commonly prescribed when dizziness comes with severe nausea or vomiting. These block certain brain signals that trigger the urge to vomit. Scopolamine, available as a prescription patch worn behind the ear, works well for motion-related dizziness by suppressing inner ear activity. It’s often used for prolonged travel like cruises.
The Epley Maneuver for Positional Vertigo
If your dizziness hits when you roll over in bed, tilt your head back, or look up, you likely have benign paroxysmal positional vertigo (BPPV). This happens when tiny calcium crystals in your inner ear drift into the wrong canal. No pill fixes this. Instead, a simple head-repositioning technique called the Epley maneuver works in about 8 out of 10 people.
During the procedure, a provider turns your head 45 degrees toward the affected ear, then guides you to lie back quickly with your head hanging slightly off the table. Your head is then slowly rotated to the opposite side, your body follows, and after a brief pause you sit upright. The whole sequence takes just a few minutes and physically moves the displaced crystals back where they belong. Many people feel immediate relief, though some need the maneuver repeated a few times. You can also learn a version to do at home.
Vitamin D and Recurring Vertigo
If you’ve had BPPV more than once, your vitamin D levels may be part of the problem. A systematic review found that vitamin D supplementation cut BPPV recurrence rates roughly in half compared to no supplementation. The benefit was strongest in people who already had low vitamin D levels. It won’t stop a current episode, but if you’re prone to repeated bouts of positional vertigo, getting your vitamin D checked and supplementing if you’re low is one of the simplest preventive steps available.
Vestibular Rehabilitation Therapy
For chronic or recurring dizziness that doesn’t resolve with medication, vestibular rehabilitation is a specialized form of physical therapy designed to retrain your balance system. The core exercises fall into a few categories: gaze stabilization (focusing on a target while slowly moving your head), balance retraining (progressing from standing with feet together to standing on one foot), walking exercises at various speeds and with head turns, and general strengthening work.
How long therapy takes varies widely. Some people need only one or two sessions to learn the exercises, while others require several months of ongoing treatment including daily practice at home. The goal is to push your brain to compensate for whatever inner ear damage or dysfunction is sending faulty signals. It’s particularly effective for people whose dizziness has lingered for weeks or months.
Hydration, Salt, and Positional Lightheadedness
Dizziness when you stand up, known as orthostatic hypotension, is one of the most common types and often the simplest to address. Your blood pressure drops temporarily because not enough blood reaches your brain as you change positions. Dehydration is a frequent culprit, and increasing your water intake can make a noticeable difference.
For people with recurring episodes, salt supplementation helps by increasing blood volume. Research published by the American Heart Association found that adding about 6 grams of sodium chloride daily improved both brain and body blood flow during standing in people prone to fainting spells, provided they didn’t already have high blood pressure. In practical terms, this means drinking more fluids and being more liberal with salt at meals, though this approach is only appropriate if your blood pressure runs normal or low.
Managing Vestibular Migraine
Vestibular migraine causes episodes of dizziness or vertigo that can last minutes to days, sometimes with a headache and sometimes without one. According to Stanford Medicine, the foundation of management is lifestyle: consistent sleep, staying hydrated, eating regular meals, moderate exercise most days, and a regular stress management practice. If episodes continue despite these changes, treatment typically combines vestibular physical therapy, certain vitamins, and preventive prescription medications to reduce both frequency and severity of attacks.
Ginger for Nausea-Related Dizziness
Ginger has modest evidence for reducing the nausea and stomach disruption that often accompanies dizziness, particularly motion sickness. Most clinical trials have used doses between 500 mg and 1,500 mg per day, either as capsules or fresh ginger. One study found it significantly reduced the stomach rhythm disturbances triggered by visual motion (the queasy feeling you get watching movement from a stationary position). It’s not a powerful vertigo treatment on its own, but it’s a reasonable add-on for nausea. The most consistently reported side effect is heartburn, especially at higher doses.
When Dizziness Signals an Emergency
Most dizziness is not dangerous, but sudden dizziness paired with certain symptoms can indicate a stroke. The CDC identifies sudden trouble walking, loss of balance, or loss of coordination as stroke warning signs, especially when combined with facial drooping, arm weakness, or difficulty speaking. Stroke treatments work best when given within three hours of the first symptoms, so noting exactly when symptoms began matters. If dizziness comes on abruptly with any of these additional signs, call 911 immediately.
