Always inform your doctor about all medications, supplements, and herbal remedies you’re taking before starting finasteride. This includes over-the-counter drugs like ibuprofen or aspirin.
Specific Interactions to Note
Finasteride can interact with several medications, potentially altering their effects or causing adverse reactions. For example, concurrent use with certain anticoagulants might increase bleeding risk. Similarly, combining finasteride with certain antihypertensives could lower blood pressure excessively.
Substances to Avoid
Grapefruit juice and some other citrus fruits contain compounds that can affect the metabolism of finasteride, leading to higher-than-expected levels in the bloodstream. Avoid these during your treatment. Alcohol consumption, while not directly interacting with finasteride, can exacerbate potential side effects. Moderation is advisable.
Interaction Summary Table
| Anticoagulants (e. g., warfarin) | Increased bleeding risk | Monitor closely; adjust dosage as needed |
| Antihypertensives (e. g., some ACE inhibitors) | Excessive blood pressure drop | Regular blood pressure monitoring; dosage adjustments may be required |
| Grapefruit Juice | Increased finasteride levels | Avoid grapefruit juice and related citrus fruits |
Reporting Side Effects
Report any unusual symptoms to your healthcare provider immediately. This proactive approach ensures appropriate management of potential interactions and minimizes any risks.
