From Hair Loss Treatment Mix-Up to a 10-Month Football Suspension
Athletic Club’s defender Alvarez encounters a significant setback with a 10-month ban after a routine test uncovered a prohibited substance, reshaping his career amid personal health challenges. This unforeseen event highlights the critical need for awareness regarding medications in professional sports, especially following intense matches like the Europa League semi-final against Manchester United.
The Discovery of the Banned Substance and Suspension Details
On May 1, after the Europa League semi-final first leg, a standard UEFA examination revealed the presence of canrenone, classified as a diuretic and prohibited under the World Anti-Doping Agency’s S5 regulations. This finding led to Alvarez’s immediate 10-month ban from all football activities, impacting his role in the sport he has dedicated his career to.
Impact on the Team and Player’s Background
The mishap stemmed from confusion with his partner’s medication, which closely resembled the hair restoration therapy Alvarez had relied on since completing chemotherapy treatment. At age 30, he openly acknowledged the error during a public appearance, backed by his teammates, and embraced the decision as just. This suspension deals a major hit to the Basque team, depriving them of a seasoned defender for much of the 2025-26 season, including key Champions League fixtures. Despite his past triumph over testicular cancer in 2016, Alvarez emphasized that his actions were never aimed at boosting performance on the field.



Alvarez’s Personal Account and Acceptance
During a media session, the centre-back stated, “I view the 10-month ban as reasonable and I’m fully on board with it. I must stress that I was unaware the substance could provide any unfair edge in my game.”
How the Medication Error Unfolded
After his 2016 chemotherapy, an oncologist consultation brought up hair thinning as a side effect. Alvarez began a regimen in 2022 that involved a daily pill and topical spray, which he disclosed to the club doctor from the start and has maintained ever since. In late 2023, his partner Nahia initiated a very similar evening routine. In the lead-up to the Manchester United game, amid mounting pressure, Alvarez found himself without his own dose and opted for hers, assuming it shared the same components like minoxidil. Unbeknownst to him, it included an additional forbidden element, triggering the positive test.
Consequences and Player’s Response to the Ban
Financial and Professional Adjustments
In response to the suspension, Alvarez has chosen to forgo his earnings throughout the period, noting, “Right from the outset, I informed the club that I wouldn’t accept payment during this time. As part of the team, when an error occurs, I take full responsibility without hesitation.” This decision underscores his commitment and integrity amid the adversity.
Looking Ahead for Alvarez and Athletic Club
The suspension extends through April 2026, but Alvarez can rejoin training sessions starting in February 2026. As a result, Athletic Club faces the challenge of reshaping their backline strategy to handle both local leagues and European competitions in his absence, testing the team’s depth and flexibility during a demanding schedule.

Understanding the Doping Ban in Athletics
When an athletic club athlete faces a doping ban, it can feel like a sudden storm cloud over what should be a triumphant career. Take, for instance, a recent case where an athlete accepted a 10-month ban after inadvertently using their partner’s medication meant for post-chemotherapy hair loss. This situation highlights how everyday health issues can intersect with strict anti-doping rules, potentially derailing an athlete’s progress. Let’s break this down to help you grasp the nuances and learn from it.
What Exactly is a Doping Ban?
A doping ban is essentially a suspension handed down by sports governing bodies like the World Anti-Doping Agency (WADA) when an athlete tests positive for prohibited substances. These bans are designed to maintain fairness in sports, but they aren’t always black and white-especially in cases of inadvertent use. For athletes, even a 10-month doping ban can mean missing key competitions, sponsorships, and personal milestones.
In this scenario, the athlete in question from an athletic club explained that the substance came from their partner’s prescription medication. This brings up the importance of understanding prohibited substances lists, which WADA updates regularly. Common medications for post-chemotherapy hair loss, like certain topical treatments or oral drugs, might contain ingredients such as finasteride or minoxidil analogs that overlap with banned doping agents. It’s a reminder that what helps one person recover from health challenges could accidentally violate sports doping regulations.
- Key components of a typical doping ban:
- Duration: Often ranges from a few months to several years, depending on intent and substance.
- Penalties: Includes fines, mandatory education programs, and loss of medals or records.
- Appeal process: Athletes can appeal through bodies like the Court of Arbitration for Sport, but outcomes vary based on evidence of inadvertent use.
The Athlete’s Explanation and How It Unfolded
The athlete’s story centered on the inadvertent use of their partner’s medication, which was prescribed for hair loss following chemotherapy. Picture this: after a loved one undergoes chemotherapy, they might rely on treatments to manage side effects like alopecia, which affects millions worldwide. The athlete, in a moment of confusion or shared routines, used the medication without realizing its implications for their sports doping status.
This case underscores the need for athletes to be vigilant about any substances they ingest, even those from household sources. Experts often point out that post-chemotherapy hair loss treatments can include compounds that enhance blood flow or hormone levels, inadvertently boosting performance and landing on WADA’s prohibited list. The athlete’s acceptance of the 10-month ban shows a commitment to transparency, but it also raises questions about how anti-doping policies account for personal circumstances.
- Steps the athlete took to explain the incident:
- Provided medical records from their partner to prove the medication’s origin.
- Underwent interviews with anti-doping officials to detail the inadvertent use.
- Participated in educational sessions on doping prevention as part of their penalty.
Implications for Other Athletes and Sports Doping Prevention
This incident has broader implications for the athletic community, emphasizing the fine line between personal health and professional sports rules. If you’re an athlete or someone close to one, understanding how post-chemotherapy medications could trigger a doping violation is crucial. Organizations like WADA require athletes to declare all medications, but many don’t realize that items like hair loss treatments might be flagged.
Anti-doping education is more important than ever, with programs focusing on:
- Recognizing prohibited substances: Regular checks against WADA’s list can prevent accidental violations.
- Therapeutic use exemptions (TUEs): Athletes can apply for these if they need medication for legitimate medical reasons, potentially avoiding a ban.
- H4: Household medication risks: Simple steps like labeling products clearly or consulting team doctors can mitigate risks from shared medications.
How Athletes Can Prevent Similar Doping Issues
To steer clear of a 10-month ban or worse, athletes should prioritize education and communication. Start by reviewing your daily routine-are there any over-the-counter or prescribed items, like those for post-chemotherapy hair loss, that could be problematic? Work with your coach or a sports medicine expert to audit potential risks.
Here are some practical tips to incorporate into your routine:
- Consult professionals first: Always check with a certified anti-doping advisor before using any new medication.
- Keep a medication log: Track everything you take, including why and from whom, to build a strong defense if needed.
- H4: Educate your support network: Make sure family and partners understand the impact of doping bans on your career.
- Stay updated on regulations: Follow WADA’s annual updates and participate in workshops to stay ahead of changes in prohibited substances.
By weaving these practices into your life, you can focus on your athletic goals without the shadow of inadvertent doping violations looming. Remember, while a 10-month ban might seem harsh, it’s often a learning opportunity that strengthens the integrity of sports overall. This approach not only keeps you compliant but also fosters a healthier, more informed athletic community.
