Patient instructions

Applying Topical Estrogen

These instructions are for compounded estrogen creams and gels applied to the skin as part of a prescriber-led hormone plan. How and where you apply them changes how much hormone you absorb, so technique matters as much as the dose. Available by prescription only.

Thin skin, rotated

Inner wrist, inner upper arm, crook of the elbow, or inner thighs — warm, thin-skinned spots absorb best. Rotate sites each day.

Two minutes of rubbing

Rub in gently for at least 2 minutes, then leave the area uncovered — ideally for 30 minutes — before anything else touches it.

It can transfer

Topical hormones rub off on people and pets. Cover the area with clothing if others may touch it, and wash that clothing separately.

How to Apply

  1. 1Wash your hands well before and after each application.
  2. 2Apply only the amount your prescriber recommended, to skin that is clean, dry, and intact — never to damaged or broken skin.
  3. 3Apply at about the same time each day. Morning or bedtime both work; pick one and keep it consistent.
  4. 4Choose a spot where the skin is warm and thin (avoid fatty areas), and rotate application sites from day to day.
  5. 5Rub the cream or gel in gently for at least 2 minutes.
  6. 6Wait at least 5 minutes before perfumes, lotions, or clothing touch the area — ideally keep it uncovered for 30 minutes.
  7. 7Do not apply any other hormone cream or gel underneath the estrogen.

Where to Apply

  • Inner wrist
  • Inner upper arm (but not all the way to the armpit)
  • Inside crook of the elbow
  • Inner thighs

Do not apply to:

  • Face
  • Neck
  • Breasts
  • Buttocks

Timing Rules

  • Apply after bathing or swimming, or wait at least 30 minutes after applying before you bathe or swim.
  • Do not exercise for at least 2 hours after applying.
  • If you miss a day, apply when you remember unless it is nearly time for the next application — then skip it. Do not double up.

Side Effects

Side effects are unlikely with topical estrogen. When they happen they are usually mild, temporary, and a sign that too much is being used. They may include:

  • Headaches
  • Fluid retention or weight gain
  • Breast tenderness or swelling
  • Irritability, anxiety, or low mood
  • Nausea or stomach upset
  • Dizziness
  • Spotting (light vaginal bleeding)

Storage

Store creams and gels at room temperature in a cool, dry area, out of reach of children and pets. Check the beyond-use date on the pharmacy label — compounded creams have shorter dating than commercial products.

When to Call the Pharmacy

  • You notice side effects — they usually mean the dose needs adjusting, and your prescriber may want to fine-tune it.
  • Someone else in the household — including a pet — may have been exposed to the cream.
  • You are unsure about your dose, the measuring device, or where to apply.
  • You are running low — compounded hormone creams are prepared to order, so plan refills a few days ahead.
