Interaction report

Dhea and reteplase

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to reteplase

reteplase falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Dhea interacts with.

Theoretically, DHEA might increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Human and laboratory research show that DHEA and DHEA-S can inhibit platelet aggregation.
Severity Moderate 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

Reteplase is a powerful clot-busting medicine given in the hospital, usually during a heart attack or other emergency. It works by breaking apart clots that are blocking blood flow, so bleeding is already its main risk. DHEA may add to that risk because lab and some human research suggest it can make platelets (the cells that help blood clot) a little less sticky.

Put simply, stacking DHEA on top of reteplase could theoretically nudge your bleeding risk higher, showing up as easy bruising, prolonged bleeding, or in serious cases internal bleeding. Keep in mind this concern is mostly theoretical, based on weak lab evidence. Since reteplase is given by your medical team in a controlled setting, tell them about any DHEA you take so they can watch you closely.

About Dhea

What is Dhea?

Dhea
  • Anti-aging and low DHEA levels
  • Mood and depression
  • Vaginal dryness and sexual health
  • Fertility support
  • Muscle mass and athletic performance
  • Adrenal insufficiency

DHEA is a natural hormone that the body makes and that declines with age, and it is sold as a supplement claiming many benefits. The evidence is mixed and limited for most uses, and because it acts as a hormone it can cause real side effects. Talk to a pharmacist or doctor before using it, especially if you have a hormone-sensitive condition.
