Testosterone vaginal cream: dosing, timing and what to expect

A compounded 20 mg/mL testosterone cream delivered intravaginally, typically with a PERL vaginal dosing applicator at 0.25 mL per click. Used for genitourinary symptoms where a local androgen effect is the goal.

Route: Vaginal
Typical dose: 5 mg (0.25 mL)
Frequency: Nightly
Half-life: Local action; systemic absorption not well characterised.

These are the numbers people actually run, drawn from the published record and from what the community has settled on over time. Educational reference, not medical advice — a starting point to work from, and one you can adjust as you learn how you respond.

How to run it

How often: Nightly
Cycle length: Continuous, reassessed with symptoms.
Half-life: Local action; systemic absorption not well characterised.
Route: Vaginal

Consistency matters more than perfect timing. Pick a slot in your day you will actually keep, and let DoseIQ handle the rest.

For women

A common starting point is 0.25 mL — 5 mg — once daily at bedtime, with a usual range of 0.25 to 0.5 mL. The applicator is a different device from the skin-cream dispenser, so check which one your pharmacy supplied before counting clicks.

What to expect

Most people tolerate Testosterone vaginal cream well. Here is what is worth knowing going in, so nothing catches you by surprise.

Compounded, so no approved label and no batch-verified potency. Evidence for the intravaginal route is thinner than for transdermal female dosing.

Known interactions

Interactions involving Testosterone vaginal cream's drug class that DoseIQ screens for. Each one cites where it comes from — an FDA label section or the published record — because an interaction warning you can't trace is just noise.

Serious Testosterone + warfarin — anticoagulation potentiated

Androgens increase warfarin's effect; INR can climb after starting or raising testosterone.

What to do: Tell the prescriber managing your warfarin about the testosterone — INR gets checked more often around any dose change.

Worth knowing Spironolactone blunts testosterone

Spironolactone blocks androgen receptors — it works directly against TRT's purpose.

What to do: Sometimes intentional (acne dosing is low); worth confirming the prescribers know about each other.

Worth knowing Finasteride/dutasteride reshape TRT's DHT arm

They block conversion of testosterone to DHT — usually the deliberate point (hair), but it changes what a given T dose does.

What to do: Nothing to do if intentional; PSA readings run ~half their true value on these, which the Markers page notes.

DoseIQ screens your whole protocol against these rules automatically — every compound, prescription and supplement you track, cross-checked as you add them. Serious flags are always free.

Preparing it

Testosterone vaginal cream does not need reconstituting — it comes ready to use. Nothing to reconstitute. One click of the PERL vaginal applicator is 0.25 mL, which at 20 mg/mL is 5 mg.
