Hair issues, taking Finasteride medication?


Hello, Doctor.
I am in the military and have visited a dermatologist who determined that I need to use finasteride.
Since military personnel frequently undergo urine drug screenings, I would like to ask if this medication will show a positive reaction for drugs in a urine test?

More Info


Finasteride is a medication primarily used to treat conditions related to androgen levels, such as benign prostatic hyperplasia (BPH) and male pattern baldness. It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT), a more potent androgen. Given your concern about drug testing in a military context, it's important to clarify how Finasteride interacts with standard drug screening protocols.

To address your question directly: No, Finasteride does not show up on standard drug tests used by military personnel or other organizations. Most drug tests are designed to detect substances such as cannabinoids, cocaine, opiates, amphetamines, and phencyclidine (PCP). Finasteride is not chemically similar to these substances and is not typically included in the panels that are screened during urine drug tests.

However, it is worth noting that while Finasteride itself will not cause a positive drug test, there are some considerations to keep in mind. For instance, the medication can have side effects, including sexual dysfunction, breast tenderness, and gastrointestinal issues, which you may have experienced. If you are experiencing side effects such as diarrhea or changes in urination, it is advisable to consult your healthcare provider. They can assess whether these symptoms are related to Finasteride or if there might be another underlying issue.

In terms of hormonal balance, there is ongoing debate about the effects of Finasteride on estrogen levels in men. While the medication is designed to lower DHT levels, some anecdotal reports suggest that it may lead to an increase in estrogen levels due to the altered hormonal balance. However, clinical studies have not consistently shown significant changes in estrogen levels among users. It is essential to monitor any unusual symptoms and discuss them with your doctor, as they can provide guidance tailored to your specific situation.

If you are concerned about the implications of taking Finasteride while in the military, it may be beneficial to have an open discussion with your prescribing physician. They can provide you with more information about the medication, its side effects, and any potential interactions with military health regulations.

In conclusion, you can rest assured that taking Finasteride will not result in a positive drug test for illicit substances. However, it is crucial to remain vigilant about any side effects and maintain open communication with your healthcare provider to ensure your treatment is effective and safe. If you have any further questions or concerns, do not hesitate to reach out to your healthcare team for support.
