Concerns About Diuretic Effectiveness and Long-Term Use Risks

Inquiry about diuretic medications?

Hello Dr.
Lin: I have been taking diuretics for 9 months.
I would like to ask you about my experience.
For the first six months, I felt that the medication was effective, and my male hormone levels were better controlled.
However, in the last two months, I feel that the medication is no longer effective, even though I have not stopped taking it.
I am puzzled as to why it worked well initially but seems ineffective now, which is why I am consulting you.
Additionally, is there a way to verify the authenticity of this medication based on the packaging or the product itself? If taken long-term, aside from potential issues with libido and ejaculation, could there be any effects or damage to the liver and kidneys? I appreciate your guidance, thank you.

If your medication was obtained from a healthcare facility or pharmacy approved by the Department of Health, there is generally no issue with counterfeit drugs.
It is recommended to consult a urologist to measure prostate size and assess whether the prostate is continuously shrinking to evaluate the effectiveness of the medication.
The medication for urinary symptoms has mild hepatotoxicity, so long-term use requires monitoring of liver function tests, particularly direct bilirubin levels.
It has relatively minimal side effects on the kidneys.

Dear Patient,
Thank you for your inquiry regarding your use of diuretics and your concerns about their effectiveness and potential long-term risks. It’s important to address these issues comprehensively, as they can significantly impact your health and well-being.

Firstly, it's not uncommon for patients to experience a change in the effectiveness of diuretics over time. Diuretics, which are often prescribed to help manage conditions such as hypertension or fluid retention, can sometimes lead to a phenomenon known as "tolerance." This means that after prolonged use, your body may become accustomed to the medication, resulting in diminished effects. If you have been taking the diuretic for nine months and have noticed a decrease in its effectiveness over the last two months, it may be worth discussing this with your healthcare provider. They might consider adjusting your dosage or switching you to a different medication to regain the desired effect.

Regarding the authenticity of your medication, it is crucial to ensure that you are taking genuine products. Most pharmaceutical companies provide specific identifiers on their packaging, such as batch numbers, expiration dates, and sometimes holograms or QR codes that can be scanned for verification. If you have concerns about the authenticity of your medication, consult your pharmacist or healthcare provider for guidance.

As for the long-term use of diuretics, there are several considerations to keep in mind. While diuretics can be effective in managing certain conditions, they can also have side effects, particularly with prolonged use. Common side effects include electrolyte imbalances, which can lead to issues such as low potassium levels (hypokalemia) or low sodium levels (hyponatremia). These imbalances can have serious consequences, including muscle weakness, arrhythmias, and other cardiovascular issues.

In terms of liver and kidney health, diuretics can place additional strain on these organs, particularly if they are used excessively or without proper medical supervision. Long-term use can lead to dehydration, which can adversely affect kidney function. It is essential to have regular check-ups that include blood tests to monitor your kidney function and electrolyte levels, especially if you are on a diuretic for an extended period.

Additionally, you mentioned concerns about sexual function, including libido and ejaculation. Some diuretics can indeed affect sexual health, leading to decreased libido or erectile dysfunction in some men. If you are experiencing these side effects, it is crucial to discuss them with your healthcare provider, as they may be able to adjust your medication or suggest alternatives that have a lower risk of sexual side effects.

In conclusion, while diuretics can be effective for managing certain health conditions, it is essential to monitor their effectiveness and side effects closely. Regular consultations with your healthcare provider will help ensure that your treatment remains effective and safe. If you notice any changes in your health or medication effectiveness, do not hesitate to reach out for professional advice.

Best wishes for your health and well-being.

Sincerely,
Doctor Q&A Teams
