Copper and Ulipristal Acetate

Here is the interaction we found between these two, with the evidence behind it.

Minor

CONTRACEPTIVE DRUGS

Why this applies to Ulipristal Acetate

Ulipristal Acetate falls under CONTRACEPTIVE DRUGS — the group Copper interacts with.

Theoretically, taking copper with contraceptive drugs might increase the levels and toxic effects of copper.
A meta-analysis of clinical studies suggests that chronic use of oral contraceptives increases serum copper levels by a mean of 57 mcg/dL. In most people, this resulted in levels above the normal reference range for copper.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the key thing to understand: this interaction runs in one direction. It's not that copper changes how well ella works, but rather that hormonal contraceptives may nudge your copper levels up a bit. The concern is really about copper building up in your body, not about your emergency contraceptive failing or causing extra side effects.

I'll be honest with you though, this is mostly theoretical and based on chronic, daily birth control pills, not a one-time dose. Ulipristal (ella) is a single tablet taken after unprotected sex, so it's very unlikely to meaningfully raise your copper at all. If you're taking a copper supplement long-term, it's worth a quick chat with your pharmacist, but a one-off dose of ella is nothing to worry about here.

About Copper

What is Copper?

  • Preventing or treating copper deficiency
  • Supporting red blood cell formation
  • Bone and connective tissue health
  • Immune support
  • Antioxidant defense
  • Balancing high zinc intake

Copper is an essential trace mineral your body needs in small amounts for making red blood cells, supporting nerves and bones, and helping enzymes work. Most people get enough copper from food, and supplements are mainly useful for diagnosed deficiency. Too much copper can be harmful, so do not take high doses without medical advice.
