Ozempic with finasteride: PSA, hormone and side-effect record
Keep the dates and numbers that make PSA and new symptoms interpretable when both medicines are taken: when each started, your PSA before and at least six months into finasteride, and any sexual side effects with the date they began.
The two medicines
Finasteride dose and reason1 mg for hair loss, or 5 mg for the prostate
Date finasteride started
Date Ozempic started, and current dose
PSA before finasteride, with date
PSA at least six months after starting finasteride (new baseline), with date
Weight when Ozempic started
Follow-up results
Write the PSA exactly as reported; the doubling rule is for comparing with ranges for untreated men.
| Date | PSA as reported | PSA doubled (if six months or more on finasteride) | Testosterone, if measured | Weight | Sexual symptoms: none, new or unchanged | Started after which medicine? |
|---|---|---|---|---|---|---|
From the labels
- Proscar: PSA falls by about 50% within six months; set a new baseline at least six months in, and have any confirmed rise from the lowest value evaluated.[1]
- Proscar: after six months or more on finasteride, double an isolated PSA before comparing it with normal ranges for untreated men.[1]
- Proscar: finasteride is cleared mainly through CYP3A4 in the liver, and food does not change how much is absorbed.[1]
- Ozempic: semaglutide showed very low potential to inhibit or induce CYP enzymes in lab studies, and the oral medicines tested with it showed no clinically relevant change in absorption.[2]
- Propecia: sexual problems that continued after stopping finasteride have been reported after approval.[3]
Important safety point
- Anyone who is or may become pregnant should not handle crushed or broken finasteride tablets.[3]
For the prescriber or urologist
- Which PSA value is my baseline on finasteride, and how often should it be repeated?
- Could weight loss on Ozempic change my PSA or testosterone in a way that affects how you read them?
- This symptom started after I added a medicine: which one is more likely, and what should we try?
- Do I need any change to either medicine, or to when I take them?
