Aloe and Drospirenone, Ethinyl Estradiol

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Drospirenone, Ethinyl Estradiol

Drospirenone, Ethinyl Estradiol falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Aloe interacts with.

Theoretically, aloe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that aloe extract induces CYP1A2 enzymes.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for your birth control pill (Yasmin, Gianvi). In some lab tests, aloe taken by mouth seemed to speed up a liver enzyme called CYP1A2. If that happened in the body, it could in theory clear the hormones a bit faster and slightly weaken them. With a contraceptive, the worry would be reduced protection against pregnancy or some breakthrough bleeding.

That said, this is very weak, test-tube only evidence, so I wouldn't lose sleep over it. Aloe gel used on your skin is not a concern here. If you take oral aloe regularly (especially the laxative kind), just mention it to your pharmacist or doctor so they can make sure your birth control stays reliable.

About Aloe

What is Aloe?

Aloe
  • Minor burns and skin irritation
  • Wound healing
  • Constipation
  • Skin hydration and moisturizing
  • Digestive complaints
  • Hair and scalp care

Aloe vera gel is widely used on the skin for minor burns and irritation, and some research suggests it may help. Aloe latex (the yellow part) is a strong laxative that can cause cramping and is not considered safe for regular use. Talk to your pharmacist or doctor before taking aloe by mouth, and avoid oral aloe during pregnancy.
