If you’re taking gabapentin and notice your hair is shedding, it could be linked to the medication. Gabapentin is one of many drugs that can have hair loss as a side effect, though it’s not common. Here’s a look at why it happens and how to combat drug-induced hair loss.

What is gabapentin?

Gabapentin (brand name Neurontin) is an anticonvulsant medication used to control nerve pain and help with seizures. It works by reducing the excitability of neurons (nerve cells) in the brain to control seizures and nerve pain (Yasaei, 2022). 

Gabapentin is approved by the US Food and Drug Administration (FDA) as an anti-seizure medication to treat epilepsy, postherpetic neuralgia (nerve pain from shingles), and restless leg syndrome. It’s also prescribed off-label for an increasing number of conditions including (Yasaei, 2022):

Does gabapentin cause hair loss?

Though not a common side effect, gabapentin may infrequently cause alopecia (hair loss) in some people. 

It can also have the opposite effect, resulting in hair growth (hirsutism) and dermatological conditions like eczema and dry skin. Other antiepileptic drugs have a higher likelihood of hair loss than gabapentin (FDA, n.d.; Wang, 2019).

Side effects of gabapentin 

Like all medications, gabapentin comes with a risk for side effects. Aside from the uncommon adverse effect of hair loss, here are some others the drug may cause (MedlinePlus, 2020; Yasaei, 2022):

  • Fatigue or drowsiness

  • Dizziness

  • Headaches

  • Memory loss

  • Swelling of the hands and feet (edema)

  • Weight gain

  • Blurred vision

  • Unsteadiness or shaking

  • Nausea or vomiting

  • Nystagmus (involuntary eye muscle movements)

  • Suicidal thoughts

Some people experience serious breathing problems, especially if taking gabapentin with central nervous system depressants like opioids (FDA, 2019). If you experience signs of an allergic reaction like itching, swelling in the face, or difficulty breathing, see a healthcare professional right away (MedlinePlus, 2020).

Other medications linked to hair loss

There are quite a few medications that trigger hair loss. Most of the time, drug-induced hair shedding reverses, and hair regrows after the medication is stopped. This doesn’t include the full list, but here are some drug types linked to hair loss (Hughes, 2021; Etminan, 2018; Watanabe, 2019):

Types of medication-induced hair loss

When a medication triggers hair loss, it usually occurs within three months of starting it. This varies based on the drug, dosage, and any sensitivities you may have. Usually, medication-induced hair loss falls into two different categories: telogen effluvium or anagen effluvium. These are based on three stages of hair growth: (Hughes, 2021).

  • Anagen (growth)

  • Catagen (transition)

  • Telogen (resting) 

Medications like gabapentin are thought to affect primarily telogen hairs. There are far fewer telogen hairs (about 15%) on the head at any given time. That’s why telogen effluvium hair loss is more gradual and usually leads to thinning rather than baldness (Hughes, 2021).  Telogen effluvium is often temporary and can be caused by other factors including illness, vitamin deficiencies, psychological stress, and weight loss (Patel, 2013).

Will hair grow back after stopping gabapentin?

In most cases, stopping a medication will result in eventual hair regrowth. Hair regrowth is usually noticed within 3–6 months but can sometimes take longer to fully recover your original hair. Sometimes it doesn’t all grow back (Hughes, 2021). 

It’s important to avoid abruptly stopping a prescribed drug without medical advice. Some medications (including gabapentin) require slow discontinuation as serious side effects like seizures can occur if you stop too rapidly (FDA, n.d.).

If you think any recent hair loss is linked to a medication you’re taking, a healthcare provider may recommend stopping the drug for three or more months and offer an alternative if one is available.

How to reverse hair loss from medication

If your hair isn’t regrowing or taking longer than expected, there are treatments that can stimulate new growth. Research shows that minoxidil (Rogaine) helps increase blood flow to affected hair follicles, boosting nutrient delivery and new hair growth (Badri, 2021).

Along with treatment, it’s important to discuss and address any underlying health conditions with your provider.
