On Wednesday, **no need to mention an amateur's name** of Oviedo, Spain, was handed a provisional suspension by the Athletics Integrity Unit (AIU) after testing positive for the banned diuretic furosemide following a 34-km trail race in October.
Álvarez placed 29th out of 61 participants, but third woman, making her eligible for prize money–and an anti-doping test. Furosemide is typically used as a masking agent to hide the presence of other prohibited substances. It has been listed as a banned substance by the World Anti-Doping Agency (WADA) since 2004.
The 27-year-old is a recreational trail runner and marathoner who competes for the Asturian Club of Mountain Runners in her hometown. Earlier this year, she also ran a half-marathon personal best of 1:21:20, at the Azkoitia-Azpeitia Media Marathon.
Chat GPT seems to think she wasn't trying to get an edge, writing:
Furosemide is widely used for non-doping medical reasons, including:
1. Medical conditions
Common reasons a doctor prescribes it include:
High blood pressure (hypertension)
Swelling/edema (from injury, travel, sodium retention, etc.)
Congestive heart failure
Kidney issues
Certain hormonal/menstrual-cycle-related bloating
Ascites or liver conditions
These are very normal—tons of non-athletes and casual athletes are on furosemide.
2. Accidental ingestion / medication mix-ups
Rare but possible:
Taking someone else’s prescribed pill accidentally
Pharmacy dispensing error
Confusing it with another medication (pill swap)
3. Contamination (less likely but not impossible)
Furosemide contamination has happened:
In supplements (very rare but documented)
In weight-loss or “detox” products
In mislabeled diuretic teas or drops
A recreational runner is more likely to use supplements casually, so contamination is possible—though still typically uncommon.
