What helps dizziness depends on what’s causing it. For general motion-related dizziness or vertigo, an over-the-counter antihistamine like meclizine is the most widely recommended option, available without a prescription at most pharmacies. But dizziness has many triggers, from dehydration to low blood sugar to inner ear problems, and each one responds to something different.
Figure Out What Kind of Dizziness You Have
Before reaching for a remedy, it helps to identify what you’re actually feeling. “Dizziness” is a broad term that covers several distinct sensations, and each points to a different cause.
If you feel like you or the room is spinning, that’s vertigo. It’s usually related to your inner ear or the balance centers in your brain. If you feel lightheaded, woozy, or like you might faint, that’s more likely tied to blood pressure, blood sugar, or dehydration. And if you simply feel unsteady on your feet without spinning or faintness, that’s a balance problem with its own set of causes. These categories overlap, but thinking about which one fits best will help you choose the right response.
Over-the-Counter Medications for Vertigo
Meclizine is the go-to OTC medication for dizziness and vertigo. It’s sold under brand names like Bonine and Dramamine Less Drowsy. For vertigo, the typical adult dose ranges from 25 to 100 mg per day, split into smaller doses throughout the day. For motion sickness specifically, 25 to 50 mg taken one hour before travel is standard, with no more than one additional dose in 24 hours.
Meclizine works by dampening the signals your inner ear sends to your brain, which reduces the spinning sensation and the nausea that comes with it. It does cause drowsiness in some people, though generally less than the original Dramamine formula (dimenhydrinate). If your dizziness is happening right now and you need quick relief, meclizine is a reasonable first choice while you sort out the underlying cause.
Drink Water and Replenish Electrolytes
Dehydration is one of the most common and fixable causes of lightheadedness. When your body is low on fluid, your blood volume drops, your blood pressure falls, and your brain gets less oxygen. The result is that woozy, about-to-faint feeling.
Plain water helps, but if you’ve been sweating, vomiting, or haven’t eaten much, you may also need electrolytes. Sodium, potassium, magnesium, and calcium all play roles in nerve signaling and muscle function, and low levels of any of them can cause dizziness on their own. An oral rehydration solution or electrolyte drink is the fastest way to restore balance. You can also make a basic version at home with water, a small amount of sugar, and a pinch of salt, though premade oral rehydration packets from a drugstore are more precise.
Eat Something if Your Blood Sugar Is Low
Blood sugar below 70 mg/dL is considered low, and dizziness is one of its hallmark symptoms. Below 54 mg/dL is classified as severely low. You don’t need a glucose meter to suspect this is your problem. If you’ve skipped a meal, exercised hard without eating, or feel shaky and sweaty along with the dizziness, low blood sugar is a strong possibility.
The fix is fast-acting sugar: fruit juice, regular soda, glucose tablets, or a few pieces of candy. Follow that with something more substantial containing protein or complex carbohydrates to keep your levels stable. If you’re prone to these episodes, keeping a snack on hand prevents the dizziness from happening in the first place.
The Epley Maneuver for Positional Vertigo
If your vertigo hits when you change head position, like rolling over in bed, looking up, or bending down, you likely have benign paroxysmal positional vertigo (BPPV). This happens when tiny calcium crystals in your inner ear drift into the wrong canal and send false motion signals to your brain.
The treatment isn’t a pill. It’s a series of head movements called the Epley maneuver that guide those crystals back where they belong. It works in about 8 out of 10 people. You can find video guides online, but having a physical therapist or doctor walk you through it the first time improves your odds of doing it correctly. Each round takes only a few minutes, and many people feel significant relief after one or two sessions.
Ginger for Nausea and Motion Sickness
Ginger has a mixed track record for dizziness itself, but it can help with the nausea that often accompanies it. One clinical study found ginger was more effective than dimenhydrinate (the active ingredient in original Dramamine) for motion sickness symptoms. Another study in naval cadets showed that 1 gram of ginger reduced the perceived severity of seasickness, though the results weren’t statistically significant. Notably, ginger did not reduce vertigo specifically in the studies that tested for it.
Most clinical research has used 250 mg to 1 g of powdered ginger root in capsule form, taken one to four times daily. If your main complaint is nausea with your dizziness, ginger is a reasonable natural option. For the spinning sensation itself, you’ll likely need something else.
Foods and Drinks That Can Trigger Dizziness
If your dizziness comes in recurring episodes, especially with headaches, your diet could be a factor. Vestibular migraines cause vertigo and are triggered by many of the same foods that trigger regular migraines. The main chemical culprits are tyramine, nitrites, and MSG, which show up across a wide range of everyday foods.
Common triggers include:
- Aged cheeses like cheddar, brie, parmesan, and Swiss
- Processed meats like salami, hot dogs, pepperoni, and jerky
- Alcohol, especially red wine, beer, and sherry
- Chocolate, nuts, and peanut butter
- MSG, which hides on labels as “natural flavoring,” “hydrolyzed protein,” or “autolyzed yeast”
- Artificial sweeteners like aspartame
Caffeine is a particular concern because both too much and inconsistent intake can trigger episodes. UC Davis Health recommends no more than two servings per day, consumed at the same time and in the same amount each day. The consistency matters as much as the quantity.
When Dizziness Signals Something Serious
Most dizziness is benign, but sudden, severe vertigo that comes with certain other symptoms can indicate a stroke affecting the brainstem or cerebellum. The warning signs to watch for include vertigo that starts abruptly and is continuous (not triggered by position changes), inability to sit upright without support, double vision, difficulty speaking or swallowing, numbness or weakness on one side of the body, or a severe new headache.
One important distinction: BPPV comes in brief bursts triggered by head movement and goes away when you hold still. A stroke-related vertigo episode is constant, lasting hours to days, and doesn’t stop when you stop moving. If your dizziness fits that second pattern, especially with any of the symptoms above, call emergency services immediately.
