Finasteride, known as Propecia or Proscar, is a medication prescribed for male pattern baldness. It functions by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone contributing to hair follicle miniaturization and hair loss. Individuals may consider discontinuing finasteride for various reasons. This article outlines what to expect when stopping the medication.
Reasons for Discontinuation
Individuals may decide to stop finasteride for several reasons. Some feel they have achieved desired hair growth and no longer need ongoing medication. Others experience side effects, such as sexual dysfunction, including decreased libido, erectile dysfunction, or reduced ejaculate volume. Concerns about potential long-term effects or the financial cost can also lead to discontinuation. Some individuals may simply choose to accept their natural hair loss progression.
The Discontinuation Process
Stopping finasteride should always involve consulting a healthcare professional. Abruptly discontinuing the medication is generally not recommended, as it may lead to a resurgence of hair loss. Medical guidance is important for personalized advice, considering an individual’s health history and reasons for stopping. A doctor can help determine if a gradual tapering approach is more suitable than stopping “cold turkey,” which can help the body adjust slowly and minimize potential withdrawal effects.
Finasteride is cleared from the body within a few days, but its effects on DHT levels can persist longer. The absence of the drug, leading to rising DHT levels, takes time to manifest. Consulting a healthcare provider ensures a smooth transition and allows for discussion of any concerns or alternative strategies.
Anticipated Changes and Side Effects
Upon discontinuing finasteride, the body’s dihydrotestosterone (DHT) levels will gradually increase, typically returning to pre-treatment concentrations. This rise in DHT can lead to hair loss resuming or accelerating to its natural progression. Shedding and hair loss may become noticeable within a few weeks to a few months after stopping, and hair counts may return to pre-treatment levels within 3 to 12 months.
Side effects experienced while on finasteride typically resolve after discontinuation. Common reactions like sexual dysfunction or breast tenderness often resolve within weeks to months. However, in some rare cases, individuals report persistent symptoms, including ongoing sexual dysfunction, mood changes like depression or anxiety, fatigue, and cognitive issues. This cluster of persistent symptoms is sometimes referred to as “post-finasteride syndrome,” though it remains a subject of ongoing research and discussion within the medical community.
Managing Hair Loss Progression
For individuals who experience renewed hair loss after discontinuing finasteride, several options exist to manage its progression. Topical treatments like minoxidil are a common alternative that can promote hair growth and slow shedding. Lifestyle adjustments, such as stress management and proper sleep, can also contribute to overall hair health.
Other non-pharmacological approaches, such as low-level laser therapy, may also be considered. In some cases, a healthcare professional might suggest switching to a different oral medication, such as dutasteride, or combining treatments for enhanced results. Regular monitoring of hair health, perhaps through scalp photography, can help track any renewed progression of male pattern baldness and allow for timely intervention.
