Hi everyone, and welcome back to Hair Loss Immersion. I’m Dr. Ghorbani, a plastic surgeon specializing in hair loss.
One of the most common concerns I hear is whether it’s safe to take finasteride while trying to conceive or during pregnancy. This question affects both men and women, and there’s a lot of misinformation circulating about it.
In this article, I’ll explain the facts about finasteride’s safety during conception and pregnancy, addressing concerns for both genders.
Why Finasteride Is Classified as a Category X Drug
Finasteride is primarily used to treat androgenetic alopecia and is FDA-approved for men. However, it’s classified as a Category X drug, meaning it has been shown to cause birth defects if taken during pregnancy.
This classification is based on animal studies where high doses of finasteride—200 mg per day—were linked to genital malformations in male monkeys.
Key points to remember:
- The typical dosage for hair loss treatment is 1 mg per day, which is 200 times lower than the doses used in these studies.
- The risk applies to male fetuses, not female fetuses.
For women:
- Avoid finasteride during pregnancy to prevent any potential harm to a male baby.
Is It Safe for Men to Use Finasteride While Trying to Conceive?
Let’s address a major concern: Can finasteride taken by men harm their partner or the baby during conception or pregnancy?
The short answer is no.
Here’s why:
- Finasteride is not excreted through semen. The drug doesn’t leave your body in this way, so it won’t pass to your partner during ejaculation.
- Even if trace amounts were present in semen, they would be in an inactive, metabolized form that poses no risk.
- The female genital tract has natural barriers that prevent drug absorption, even if active finasteride were somehow present.
Bottom line: If you’re a man taking finasteride, you don’t need to stop the medication while trying to conceive or if your partner is already pregnant.
Stopping Finasteride for Peace of Mind
Despite the scientific evidence, I understand that some people might still feel uneasy about continuing finasteride during conception.
Here’s my recommendation for peace of mind:
- Stop finasteride one month before trying to conceive. This allows time for the drug to clear from your system.
- Once your partner is pregnant, you can safely resume finasteride without any concerns.
For most people, this approach provides reassurance while ensuring continuity in their hair loss treatment.
Special Considerations for Women
For women, the situation is different. Finasteride should only be used as an off-label treatment under strict medical supervision.
Key guidelines for women:
- Never use finasteride during pregnancy due to the risk of birth defects in male fetuses.
- If you’re planning to conceive, stop finasteride at least one month beforehand.
- If you discover you’re pregnant while taking finasteride, stop immediately and consult your doctor.
Doctors often recommend using finasteride alongside a reliable contraceptive to avoid accidental exposure during pregnancy.
Good news for women:
- Finasteride has a short half-life, meaning it clears from the bloodstream quickly after stopping.
- During pregnancy, hormonal changes naturally improve hair health, reducing the need for hair loss treatments.
Once you’ve given birth and finished breastfeeding, you can consider restarting finasteride under your doctor’s guidance.
Conclusion
Finasteride is a powerful tool for managing hair loss, but its use during conception and pregnancy comes with specific considerations.
For men: You can safely continue taking finasteride while trying to conceive or if your partner is pregnant.
For women: Avoid using finasteride during pregnancy and take necessary precautions to prevent exposure.
