Travelers who use progesterone overseas may search for Utrogestan 100mg in Vietnam because the active ingredient—micronized progesterone—is familiar from their existing HRT. The important question is not only whether a brand contains progesterone, but whether the exact local formulation matches what has been prescribed.
Quick Answer
Utrogestan contains micronized progesterone, which is structurally identical to progesterone naturally produced by the body. However, Utrogestan packaging, approved routes and inactive ingredients can vary by country. Travelers in Vietnam should have the exact product and their existing prescription checked by a pharmacist or doctor before using it as a replacement.
Medical Safety Alert
Utrogestan is a prescription hormone medicine. This article does not provide a dosing schedule and should not be used to start progesterone or modify an existing HRT regimen. The amount and pattern of progesterone required can depend on the estrogen regimen and individual clinical factors.
Is Utrogestan Bioidentical Progesterone?
NHS information describes Utrogestan as a medicine containing micronized progesterone and notes that this progesterone is identical to the hormone produced naturally by the body. This is why micronized progesterone is often described as body-identical or bioidentical progesterone.
“Bioidentical progesterone” describes the progesterone molecule. It does not mean every capsule with micronized progesterone has the same excipients, approved route or instructions.
Utrogestan 100mg — Micronized Progesterone

Active ingredient: Micronized progesterone.
Why travelers ask about it: International patients may already use micronized progesterone as part of a clinician-prescribed hormone therapy regimen.
Important: Besins Healthcare states that indications and product information may differ between countries. Check the exact Vietnam-market package information and your prescription before use.
Does Utrogestan contain peanut oil?
This question needs to be answered from the exact product leaflet, not from the brand name alone. Inactive ingredients can change between countries and formulations.
For example, current UK product information for Utrogestan lists refined sunflower oil and soya lecithin among the capsule ingredients. Other progesterone products or Utrogestan presentations marketed in other countries may have different excipients.
If your existing progesterone prescription specifically contains peanut oil, or if you are trying to avoid peanut, soy, gelatin or another ingredient, tell the pharmacist. Having the same active ingredient does not guarantee the same excipient profile.
Can Utrogestan be used instead of another progesterone capsule?
Not automatically. A pharmacist or doctor should compare the active ingredient, medicine strength, pharmaceutical form, administration route, excipients and intended clinical use.

What to Check Before Using a Progesterone Product in Vietnam
- Active ingredient: Confirm whether your prescription specifies micronized progesterone or another progestogen.
- Exact formulation: Do not assume similarly named capsules have identical approved uses or routes.
- Excipients: Check the local leaflet if you have peanut, soy, gelatin or other allergies or sensitivities.
- Existing prescription: Continue to follow the regimen prescribed by your healthcare professional unless it is professionally changed.
- Current packaging: Ask a pharmacist to review the actual box being supplied rather than relying on an online photograph from another country.
When to Seek Medical Care
- Chest pain associated with sudden shortness of breath.
- New pain, redness or swelling in one leg.
- Sudden speech difficulty, facial weakness or weakness of an arm or leg.
- Heavy, persistent or unexpected vaginal bleeding that requires medical assessment.
- Swelling of the mouth, tongue or throat or difficulty breathing after taking a medicine.
These warning signs require medical evaluation and should not be managed by changing or stopping hormone medicines based solely on online information.
