Finasteride
別名: Proscar, Propecia
> **CRITICAL WARNING FOR PREGNANT WOMEN**: Women who are pregnant or may become pregnant must **NOT** handle crushed or broken tablets. The active ingredient can be absorbed through the skin and cause severe birth defects in male fetuses. * **Patience is Key**: Therapy might be prolonged (several weeks to months) before noticeable efficacy can be determined. Regular dosing compliance is mandatory for success. * **Lifelong Commitment**: Once the drug is stopped, the prostate will typically start growing again. Long-term therapy is usually required unless the dog is neutered. * **Breeding**: This medication is often chosen because it generally preserves fertility and breeding ability in stud dogs, though minor decreases in ejaculate volume may occur.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。
