Gamma-linolenic Acid (gla) and Gestodene

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Gestodene and Gamma-linolenic Acid (gla) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Gamma-linolenic Acid (gla) safety at a glance

Gamma-linolenic Ac... overall Use caution Usually well tolerated, but quality and source of the oil matter and some people have side effects.
Pregnancy Avoid Not enough safety data; some sources are traditionally avoided in pregnancy, so it is best to avoid.
Breastfeeding Use caution Safety is not well established, so check with your doctor before use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Gestodene

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gestodene is filed under 3 classifications — contraceptive drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, oral drugs. Gamma-linolenic Acid (gla) has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Gestodene’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Gamma-linolenic Acid (gla) Itself Has Been Linked To

This is not an interaction — nothing below involves Gestodene. It is the side-effect record for Gamma-linolenic Acid (gla) on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Gamma-linolenic Acid (gla), this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

Everything above comes from the Natural Medicines adverse-effect record for Gamma-linolenic Acid (gla) — expand a row for the licensed statement it rests on. We haven’t matched Gestodene to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Gestodene.

See Every Supplement That Interacts With Gestodene

This page covers Gamma-linolenic Acid (gla) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Gestodene page lists 59 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), St. John's Wort (major), Adrafinil (moderate), Alfalfa (moderate) and Anise (moderate).

From our pharmacist’s overview on the Gestodene page

“Gestodene, the progestin in the low-dose birth control pill Minesse, is a medication where a weakened dose has a real consequence: unintended pregnancy. So the 59 supplements and herbs on file deserve genuine vigilance, and the two rated major most of all.”

About Gamma-linolenic Acid (gla)

What is Gamma-linolenic Acid (gla)?

  • Eczema and dry skin
  • Rheumatoid arthritis
  • Diabetic nerve pain
  • PMS and breast pain
  • Menopausal symptoms

Gamma-linolenic acid (GLA) is an omega-6 fatty acid found in oils like evening primrose and borage. It is most studied for skin conditions, joint pain, and nerve pain, but the evidence is mixed and far from conclusive. It is generally well tolerated, but talk with your pharmacist or doctor before starting, especially if you are pregnant, breastfeeding, or take other medicines.

Seed oil (from evening primrose, borage, or black currant seeds) · Capsules, softgels, and oils (evening primrose oil, borage oil, black currant seed oil)

An interaction check asks whether these two react with each other — it does not ask whether Gamma-linolenic Acid (gla) is a good idea for someone in your situation. Here is what our Gamma-linolenic Acid (gla) record says about it on its own.

Gamma-linolenic Acid (gla): dosing

There is no single official or standardized dose of GLA. The amount of GLA varies depending on the source oil, since evening primrose, borage, and black currant seed oils contain different concentrations.Because products differ so much, the best approach is to follow the directions on the product label and choose a reputable brand. A pharmacist can help you compare products and figure out an appropriate amount for your situation.Do not assume more is better.
