Gabapentin and Dizziness: How Common It Is and Practical Ways to Manage It

Dizziness is a common side effect of gabapentin and can occur in a significant number of users, especially during dose increases or at higher doses. Clinical trials consistently show dizziness as one of the most frequent reasons people stop gabapentin. ^[1] Across controlled studies, dizziness occurred in about 28% of people taking gabapentin versus about 8% on placebo. ^[1] Dizziness and sleepiness (somnolence) are often paired and tend to be more noticeable when starting or increasing the dose. ^[1] Consumer medication guides also warn that gabapentin can slow thinking and motor skills, so caution is advised with activities like driving until you know how you respond. ^{[2] [3] [4]}

How Common Is Dizziness with Gabapentin?

• Frequent side effect: Dizziness is among the most commonly reported adverse effects of gabapentin in clinical trials. ^[1]
• Incidence in trials: In postherpetic neuralgia studies, dizziness occurred in about 28% of gabapentin users versus 8% with placebo; somnolence occurred in 21% versus 5% on placebo. ^{[5] [6] [7] [8]}
• Reason for discontinuation: Dizziness and sleepiness are among the top reasons people stop taking gabapentin. ^[1]
• Typical experience: Dizziness may be more prominent early in treatment and may improve as your body adjusts. ^{[9] [10]}

Why Gabapentin Causes Dizziness

Gabapentin affects the nervous system and can slow certain brain and coordination functions. This can lead to symptoms like dizziness, sleepiness, and balance issues, which may raise the risk of falls, especially in older adults. ^{[11] [12] [13]} The effect can be stronger if combined with alcohol or other sedating medicines. ^{[2] [3] [4]}

Practical Steps to Manage Dizziness

Most people can reduce dizziness with a few adjustments and safety steps. ^{[9] [10]}

Immediate Safety

• Pause risky activities: Avoid driving, operating machinery, or climbing ladders until you know how gabapentin affects you. ^{[2] [3] [4]}
• Prevent falls: Move slowly from sitting or lying to standing, use handrails, and keep walkways well lit and uncluttered. ^{[11] [12] [13]}
• Skip alcohol: Alcohol can worsen dizziness and sleepiness. ^{[2] [3] [4]}

Dosing and Timing

• Start low, go slow: If you just began gabapentin or increased the dose, discuss a slower titration with your clinician; gradual increases often lessen dizziness. ^{[1] [5] [6] [7] [8]}
• Adjust schedule: Some people take higher doses in the evening to reduce daytime dizziness; ask your clinician before changing timing. ^{[9] [10]}
• Consider formulations: Extended-release or gastroretentive versions used for postherpetic neuralgia may have lower rates of dizziness than immediate-release taken three times daily, though individual responses vary. ^{[14] [15] [16]}

Review Other Medications

• Check interactions: Combining gabapentin with other sedating drugs (e.g., opioids, sleep aids, some anxiety meds) can increase dizziness. ^[17]
• Coordinate care: Let your clinician know all medicines and supplements you use to adjust safely. ^[17]

Hydration and Lifestyle

• Stay hydrated and eat regularly: Dehydration or low blood sugar can worsen lightheadedness. ^{[9] [10]}
• Get up slowly: Orthostatic strategies like sitting at the edge of the bed before standing can help. ^{[9] [10]}

When to Call Your Clinician

• Persistent or severe dizziness: If dizziness doesn’t improve after a few days or affects daily function, ask about dose reduction or alternative therapy. ^[1]
• New neurological symptoms: Double vision, trouble speaking, or marked coordination problems need prompt medical advice. ^{[11] [12] [13]}
• Kidney issues: If you have reduced kidney function, you may be more sensitive to gabapentin and need dose adjustments to avoid toxicity. ^{[18] [19]}

At‑Home Safety Checklist

• Avoid alcohol and sedatives unless cleared by your clinician. ^{[2] [3] [4]}
• Use non‑slip shoes and keep floors clear to reduce fall risk. ^{[11] [12] [13]}
• Plan doses and changes with your clinician; do not adjust on your own. ^{[9] [10]}
• Monitor symptoms: Track when dizziness occurs (after dosing, mornings, with standing) to guide adjustments. ^{[9] [10]}

Frequently Asked Questions

Will dizziness go away?

It often improves as your body adapts, especially with slow dose titration. ^{[9] [10]}

Can I drive while taking gabapentin?

Wait until you know how gabapentin affects you; it can slow reaction time and coordination. ^{[2] [3] [4]}

Are certain doses more likely to cause dizziness?

Higher doses and rapid increases are more likely to cause dizziness, and many trials reported it up to 3,600 mg/day. ^{[1] [5] [6] [7] [8]}

Bottom Line

Dizziness is a well‑recognized and common side effect of gabapentin, particularly early in treatment or at higher doses. ^[1] Most people can manage it with safety precautions, slower dose increases, avoiding alcohol and other sedatives, and discussing timing or formulation options with their clinician. ^{[9] [10] [2] [3] [4] [14]} If dizziness is severe or persistent, or if you have kidney problems, contact your clinician to review dosing and alternatives. ^{[1] [18] [19]}
