# Spironolactone for female hair loss guide

> How to take prescribed 50mg spironolactone for off-label female-pattern hair loss, and the potassium, kidney and pregnancy checks around it.

Spironolactone is prescribed off-label for female-pattern hair loss. This guide covers how to take a prescribed 50 mg dose, what to watch for, and when to contact your doctor.

<Warning>
  Use of spironolactone for female-pattern hair loss is off-label. The prescriber decides whether kidney function, potassium, blood pressure and pregnancy status need checking before starting or changing dose.
</Warning>

## How to use

Two rules apply together for as long as you are on it — the daily dose, and what
must not be taken alongside it.

<CardGroup cols={2}>
  <Card title="Take 50 mg once daily as prescribed" icon="pill">
    Take the tablet with food at a consistent time. Because it can increase urination, a morning dose may be more convenient.
  </Card>

  <Card title="Avoid unreviewed potassium" icon="flask">
    Do not add potassium supplements, potassium-containing salt substitutes, or another potassium-sparing diuretic unless your clinician approves. Check before using anti-inflammatory painkillers regularly.

| ----------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Diuretic and blood-pressure effects | More frequent urination, thirst, headache, tiredness, and dizziness. Rise slowly and discuss persistent symptoms rather than changing fluid or salt intake abruptly. |
| Potassium and hormonal effects      | High potassium can cause weakness, tingling, or an abnormal heartbeat. Breast tenderness and menstrual changes can also occur.                                       |

## Contact your doctor if

* A slow or irregular heartbeat, marked weakness, paralysis, fainting, or severe breathing difficulty — seek urgent care
* Persistent vomiting or diarrhoea, dehydration, very low urine output, or troublesome dizziness
* Pregnancy occurs or is planned, or a new medicine may affect potassium or kidney function

## Storage

Keep in the original package, away from moisture and direct heat, and out of children's reach. Follow the temperature limit on your pack and do not use it after the expiry date.

## What to expect

Hair treatment is gradual. Early shedding can occur, and photographs taken in the same light are more useful than day-to-day checking. The doctor normally reviews tolerance and progress after several months; continue only while the balance of benefit and risk remains appropriate.
