Does finasteride 1 mg list breast changes?

Breast tenderness and enlargement are listed for finasteride after marketing. In the PROPECIA 1 mg trials, those incidences were not different from placebo. Male breast cancer is also listed; the relationship with long-term use is unknown. A new lump, discharge, or enlargement is a same-week call, not a year-three photo wait. Finpecia 1 mg does not drop that line if a breast changes.

01Why this is not the libido table

Forest-green still life: soft caution cloth, small tablet

Breast lines are not in Table 1's 1.8 / 1.3 / 1.2 sexual percents. Mixing them into one 'side effects soup' hides which sentence is a trial frequency and which is a postmarketing report.

Sexual frequencies have their own libido-line probe. This URL stays on breast.

03What the 1 mg trials actually counted

Breast tenderness, breast enlargement, hypersensitivity reactions, and testicular pain were not different from placebo in the PROPECIA studies. That is a trial-frequency sentence, not a 'never happens' sentence.

Common labelled adverse reactions at 1% or more and greater than placebo were the sexual three, not breast pain.

04What showed up after the tablet was marketed

Postmarketing breast disorders include breast tenderness and enlargement. Neoplasms listed include male breast cancer. Report both. Do not wait for a year-three hair photo.

Rash, pruritus, urticaria, and angioedema (lips, tongue, throat, face) are the hypersensitivity cluster. Swelling of the mouth is a stop, not a breast-line cousin you watch.

05When a breast change is a same-week call

New lump, nipple discharge, pain that is new, or visible enlargement. Take the 1 mg bottle to the visit so nobody assumes you are on 5 mg.

Stopping for a breast workup does not need a taper. The stop probe is the hair-exit clock, not a reason to delay the call.

06Does Finpecia 1 mg skip breast language?

No. Same INN. An export insert that stays silent is a bad insert, not a safer tablet. The 1 mg vault keeps postmarketing breast language in the monograph.

Do not stack an unmarked hormone cream from the same cart. That is a second product with its own breast story.

Vault consult

Answers follow the U.S. Propecia label.

Hana I. The 1 mg trials said breast tenderness matched placebo. Can I ignore a sore nipple?

Vault reply

No. Trial frequencies matched placebo. Postmarketing still lists tenderness and enlargement. A new breast change is a call, not a Table 1 argument.

Victor Q. Does Finpecia 1 mg cause male breast cancer?

Vault reply

Male breast cancer is listed. The relationship with long-term use is unknown. This page will not invent a 1 mg rate from 5 mg BPH trials.

Leona J. Lips swelled after a week on 1 mg. Is that the breast line?

Vault reply

That is the hypersensitivity cluster (angioedema). Stop and get urgent care. It is not a breast-tenderness wait.
