The most effective way to stop BPPV is a simple head repositioning maneuver that guides loose calcium crystals out of the spinning-sensing canals in your inner ear. When performed correctly, these maneuvers resolve symptoms in 64% to 93% of people after just one session. Most cases of BPPV can be treated in a single office visit, and some maneuvers can even be done at home.
What Causes BPPV
BPPV happens when tiny calcium crystals called otoconia break free from their normal spot on a sensory organ in your inner ear. These crystals are supposed to stay put, but when they detach, they drift into one of three fluid-filled semicircular canals that detect head rotation. The posterior canal is affected most often because gravity naturally pulls loose crystals toward it.
Once crystals settle in a canal, they sit quietly until you move your head. Rolling over in bed, looking up at a shelf, or tilting your head back in a dentist’s chair shifts the crystals to the lowest point of the canal, dragging fluid along with them. That fluid movement tricks your brain into thinking your head is spinning when it isn’t, producing the classic burst of intense vertigo and involuntary eye jerking. Each episode typically lasts less than a minute, but it can be disorienting enough to cause nausea and unsteadiness for hours afterward.
The Epley Maneuver: First-Line Treatment
The canalith repositioning procedure, commonly called the Epley maneuver, is the standard treatment for posterior canal BPPV. It uses a specific sequence of head positions to float the loose crystals out of the semicircular canal and back into an area of the inner ear where they no longer cause problems. A trained clinician can usually complete it in about 15 minutes.
The sequence works like this:
- Step 1: You sit upright on an exam table and turn your head 45 degrees toward the affected ear.
- Step 2: You lie back quickly so your head hangs slightly off the edge of the table, still turned. This is the step where vertigo often flares up briefly.
- Step 3: Your head is slowly rotated to the opposite side.
- Step 4: Your whole body rolls to align with your head, so you’re lying on your side.
- Step 5: You stay on your side for a few moments, then sit upright.
Each position is held for about 20 to 30 seconds before moving to the next. The vertigo you feel during the procedure is actually a sign the crystals are moving, which means it’s working. Some people need the maneuver repeated two or three times in the same visit to fully clear the canal.
Figuring Out Which Ear Is Affected
Before performing any repositioning maneuver, it’s important to know which ear contains the loose crystals. Clinicians determine this with the Dix-Hallpike test: you sit on an exam table, turn your head to one side, and are guided quickly onto your back with your head hanging slightly over the edge. If the test triggers vertigo and your eyes start jerking involuntarily, the affected ear is the one facing the floor. For example, if symptoms appear when your right ear is down, the crystals are in your right ear. This matters because performing a repositioning maneuver on the wrong side won’t help.
If you’re trying to identify the affected ear at home, pay attention to which direction triggers your vertigo. If rolling onto your right side in bed sets it off, the right ear is likely the problem.
An At-Home Alternative: The Half-Somersault
The half-somersault maneuver, developed by Dr. Carol Foster at the University of Colorado, is a practical option for treating BPPV at home. It’s easier to perform alone than the Epley because you don’t need to hang your head off the edge of a bed. For the right ear:
- Kneel on the floor and tilt your chin down toward the ground.
- Place the top of your head on the floor as if you’re about to do a somersault.
- Turn your head to face your right elbow.
- Raise your head quickly back to a level position (still kneeling).
- Raise your head fully upright.
Hold each position for about 15 to 30 seconds or until any dizziness fades before moving to the next step. If your left ear is affected, you’d turn to face your left elbow instead. You may need to repeat the maneuver a few times in a row, waiting a few minutes between attempts. If your vertigo doesn’t improve after several tries over a couple of days, it’s worth having a clinician confirm your diagnosis and perform the maneuver in the office.
What to Do After a Repositioning Maneuver
Older guidelines used to recommend sleeping propped up or avoiding certain head positions for days after treatment. Current guidance from the Academy of Neurologic Physical Therapy is much simpler: you can sleep normally that night without extra pillows. Starting the next day, move your head as you normally would. Restricting your movement isn’t necessary and won’t improve outcomes. Some mild unsteadiness or a “foggy” sensation can linger for a day or two after treatment as your brain recalibrates, but the intense spinning episodes should stop immediately if the crystals have been successfully repositioned.
Recurrence and How to Reduce It
BPPV does come back for some people. In one large study, about 9% of patients experienced a recurrence, with the highest rate (30%) happening within the first six months. Adults over 65 were five times more likely to have a recurrence within the first year compared to younger adults. When BPPV does return, the same repositioning maneuvers work again.
Vitamin D deficiency appears to play a meaningful role in recurrence. A randomized controlled trial published in the journal Neurology found that people with low vitamin D levels who took vitamin D and calcium supplements had a 24% reduction in their annual recurrence rate. The benefit was strongest for those with severe deficiency: people whose vitamin D levels started below 10 ng/mL saw a 45% reduction. The supplementation dose used in the study was 800 IU of vitamin D and 1,000 mg of calcium carbonate per day. If you’ve had repeated episodes of BPPV, getting your vitamin D level checked is a reasonable step.
Signs That It Might Not Be BPPV
BPPV has a distinctive pattern: brief episodes of spinning triggered by specific head movements, lasting under a minute, with no hearing loss or other neurological symptoms. If your vertigo doesn’t fit that pattern, something else may be going on. Symptoms that point away from BPPV and toward a more serious cause include progressive or one-sided hearing loss, vertigo that lasts for hours at a time, numbness or weakness on one side of the body, difficulty speaking or swallowing, and eye movements that don’t fade after 30 to 60 seconds. These can indicate problems in the brain rather than the inner ear, and they warrant prompt medical evaluation.
BPPV can also affect the horizontal semicircular canal rather than the more common posterior canal. Horizontal canal BPPV produces vertigo when you roll your head side to side while lying flat, and it requires a different repositioning technique. If standard maneuvers aren’t working, this variant may be the reason.
