Brivaracetam, a relatively new antiepileptic medication, has been gaining popularity for its efficacy in managing partial-onset seizures. However, as with any medication, concerns about its side effects have been raised. One of the most pressing concerns is whether brivaracetam causes hair loss. In this article, we will delve into the available research, explore the possible mechanisms behind hair loss, and provide valuable insights for individuals taking this medication.
Understanding Brivaracetam and Its Mechanism of Action
Brivaracetam, marketed under the brand name Briviact, is a high-affinity synaptic vesicle protein 2A (SV2A) ligand. It works by binding to SV2A, a protein found in the brain, which is involved in the regulation of neurotransmitter release. By modulating the activity of SV2A, brivaracetam reduces the excitability of neurons, thereby decreasing the frequency and severity of seizures.
Brivaracetam’s Pharmacokinetics and Metabolism
Brivaracetam is rapidly absorbed after oral administration, with peak plasma concentrations reached within 1 hour. It is extensively metabolized in the liver by the cytochrome P450 enzyme system, primarily by the CYP2C8 and CYP3A4 isoforms. The metabolites of brivaracetam are then excreted in the urine and feces.
Exploring the Relationship Between Brivaracetam and Hair Loss
Hair loss, also known as alopecia, is a common side effect of many medications, including antiepileptic drugs. While the exact mechanism of hair loss associated with brivaracetam is not fully understood, several theories have been proposed:
Androgenetic Alopecia
Androgenetic alopecia, also known as male/female pattern baldness, is a common form of hair loss. It is characterized by the conversion of testosterone to dihydrotestosterone (DHT), which leads to hair follicle miniaturization and eventually hair loss. Some research suggests that brivaracetam may increase the levels of DHT, thereby contributing to hair loss.
Telogen Effluvium
Telogen effluvium is a condition characterized by an increase in the number of hair follicles that enter the telogen phase, leading to excessive hair shedding. This condition can be triggered by various factors, including medication, stress, and hormonal changes. Brivaracetam may cause telogen effluvium by altering the normal hair growth cycle.
Research Findings on Brivaracetam and Hair Loss
Several studies have investigated the safety and efficacy of brivaracetam, but few have specifically addressed the issue of hair loss. A review of the available literature reveals:
Clinical Trials
In a phase III clinical trial, 1.4% of patients treated with brivaracetam reported hair loss, compared to 0.6% of patients receiving a placebo. Another study found that 2.2% of patients experienced hair loss during the open-label extension phase of a brivaracetam trial.
Post-Marketing Surveillance
A review of post-marketing surveillance data revealed that hair loss was reported in 1.1% of patients taking brivaracetam. However, it is essential to note that post-marketing surveillance data may be subject to underreporting and biases.
Managing Hair Loss Associated with Brivaracetam
While the evidence for brivaracetam-induced hair loss is limited, it is essential to address this concern for individuals taking the medication. Here are some strategies to manage hair loss:
Minoxidil
Minoxidil, a topical medication, has been shown to promote hair growth and slow down hair loss. It is available over-the-counter and can be applied directly to the scalp.
Low-Level Laser Therapy
Low-level laser therapy (LLLT) has been found to stimulate hair growth and increase hair density. LLLT devices are available for home use and can be used in conjunction with other treatments.
Dietary Changes
A balanced diet rich in vitamins and minerals, particularly those that promote hair growth such as biotin, vitamin D, and omega-3 fatty acids, can help manage hair loss.
Conclusion
While the evidence for brivaracetam-induced hair loss is limited, it is essential to acknowledge the concerns of individuals taking this medication. By understanding the possible mechanisms behind hair loss and exploring management strategies, individuals can take proactive steps to mitigate this potential side effect. If you are experiencing hair loss while taking brivaracetam, consult your healthcare provider to discuss the best course of action.

What is Brivaracetam and how does it work?
Brivaracetam is an antiepileptic medication used to treat partial-onset seizures in adults and children. It belongs to a class of medications known as pyrrolidine derivatives, which work by binding to specific receptors in the brain called synaptic vesicle protein 2A (SV2A). By binding to these receptors, Brivaracetam helps to reduce the abnormal electrical activity in the brain that causes seizures.
The exact mechanism of action of Brivaracetam is not fully understood, but it is thought to involve the modulation of neurotransmitter release and the reduction of excitatory neurotransmitter activity. This helps to stabilize the electrical activity in the brain and prevent seizures from occurring. Brivaracetam is available in oral and intravenous formulations and is typically taken once or twice daily.
