Can someone who may be pregnant handle finasteride 1 mg?

No. Women who are or may potentially be pregnant should not handle crushed or broken finasteride 1 mg tablets. The coat blocks skin contact only while the tablet stays whole. If contact happens, wash the skin with soap and water. Semen was measured in 35 men on 1 mg for 6 weeks; couple counselling still belongs to the clinician. Finpecia 1 mg does not soften that warning.

01Where the bottle should not live

Forest-green still life: gloves beside a whole tablet, crumbs forbidden

A shared bathroom cup next to prenatal vitamins is a bad home for broken 1 mg fragments. Keep whole tablets in a closed container, away from a counter where tablets get split.

Finpecia 1 mg blisters still open into the same handling rule. Foil does not replace the coat once a tablet is snapped.

02Why a male fetus is the named risk

Finasteride blocks Type II 5-alpha-reductase. DHT is needed for normal development of male genitalia. Abnormal external genitalia in male fetuses is the expected class effect when that conversion is blocked in pregnancy.

Pregnancy is a contraindication on this 1 mg label. The hair tablet is not a women's drug with a special chapter.

03Does an export name drop the handling line?

Crushed-tablet handling stays whenever the tablet is finasteride 1 mg. The monograph on the 1 mg vault repeats it. This probe is only the pregnancy-handling job.

Do not hide the bottle. The person who might become pregnant needs to know what not to touch.

04What the semen study actually measured

Semen levels were measured in 35 men taking finasteride 1 mg/day for 6 weeks. In 21 of 35 samples, finasteride was undetectable (below 0.2 ng/mL). The mean was 0.26 ng/mL. The highest value was 1.52 ng/mL.

Using that highest semen level and assuming 100% absorption from a 5 mL ejaculate per day, estimated vaginal exposure was up to 7.6 ng per day. The label compares that with a 5 microgram dose that did not change circulating DHT in men. Couple counselling still belongs to the clinician.

05What to do after skin contact

If a pregnant woman comes in contact with crushed or broken tablets, the contact area should be washed immediately with soap and water. Do not wait for a clinic callback to wash.

Then call the clinician who knows the pregnancy. This page will not invent a blood test or an antidote dose.

06Why the film coat matters on a whole tablet

PROPECIA tablets are coated and will prevent contact with the active ingredient during normal handling, provided the tablets have not been broken or crushed. That is a handling sentence, not a cooking tip.

A pill cutter on the kitchen counter defeats the coat. The split note is the dose-form page. This one is the pregnancy exposure page.

Vault consult

Answers follow the U.S. Propecia label.

Leila O. I only touched a whole Finpecia 1 mg tablet. Is that the crushed-tablet warning?

Vault reply

The coat is meant to prevent contact during normal handling of an intact tablet. The stop is crushed or broken tablets. If a tablet is chipped, treat it as broken and wash if it touched skin.

Craig Y. We want a pregnancy. Does he have to stop 1 mg because of semen?

Vault reply

The 35-man, 6-week semen study is in the label, including the 7.6 ng per day estimate from the highest sample. Whether he stays on is a couple-and-clinician decision. Do not hide the bottle, and do not crush tablets in the house.

Mina U. She got dust on her hand from a split tablet. What first?

Vault reply

Wash with soap and water now. Then call the clinician who knows the pregnancy. The label's first action after contact is the wash, not a wait-and-see.
