Consulting Your Doctor: Blood Tests and Quinine Treatment Insights - Internal Medicine

Share to:

Medication consultation, laboratory consultation?


Thank you for your response, Doctor.
I would like to ask, in addition to the blood tests I previously underwent, what other tests would you recommend to confirm whether I need to start treatment with quinine? By the way, I have been on the medication for three days; can I stop taking it at any time? Last night, I felt quite fatigued and experienced dizziness when falling asleep, along with afterimages when looking at the ceiling, but I felt normal again in the morning.
Could this be a side effect of the medication? 😅 Thank you, Doctor.

Hello, thank you for your inquiry.
You might want to ask your physician whether you need to test for SSA/SSB, CCP or ACPA, ESR, etc.
Quinine can be discontinued at any time.
Quinine may cause headaches as a side effect, while dizziness is rare, and visual disturbances are a "rare" side effect that may occur only after long-term use.

More Info


When it comes to blood tests and the use of quinine for treatment, it's essential to approach the situation with a comprehensive understanding of both the medical implications and the specific circumstances surrounding your health. Quinine is primarily used to treat malaria and certain muscle cramps, but it can have side effects and interactions that need to be carefully monitored.


Understanding Blood Tests
Blood tests are crucial diagnostic tools that provide insights into various health conditions. They can help assess organ function, detect infections, and evaluate blood cell counts, among other things. If you are considering quinine treatment, it’s important to have a clear understanding of your blood test results, particularly those related to liver function, kidney function, and blood cell counts.

1. Liver Function Tests (LFTs): Quinine is metabolized in the liver, so it's vital to ensure that your liver is functioning properly. Elevated liver enzymes could indicate liver damage or dysfunction, which may necessitate a reevaluation of quinine use.

2. Kidney Function Tests: Since quinine is also excreted through the kidneys, assessing your kidney function through tests like serum creatinine and blood urea nitrogen (BUN) is important. Impaired kidney function could lead to increased levels of quinine in the blood, raising the risk of toxicity.

3. Complete Blood Count (CBC): This test can help identify any abnormalities in your blood cells, such as low platelet counts or anemia, which could be exacerbated by quinine.


Quinine Treatment Considerations
Regarding your question about stopping quinine after three days of treatment, it’s crucial to consult your healthcare provider before making any changes to your medication regimen. Quinine can have withdrawal effects, and abruptly stopping it might not be advisable, especially if it was prescribed for a specific condition.


Side Effects of Quinine
The symptoms you described—feeling dizzy and experiencing visual disturbances—could potentially be side effects of quinine. Common side effects include:
- Tinnitus (ringing in the ears)
- Dizziness
- Headaches
- Visual disturbances
If these symptoms persist or worsen, it’s essential to contact your healthcare provider immediately. They may need to adjust your dosage or consider alternative treatments.


Recommended Actions
1. Follow-Up Testing: If you haven’t already, ask your doctor about additional blood tests to monitor liver and kidney function, especially if you are experiencing side effects.

2. Medication Review: Discuss with your doctor the possibility of continuing or adjusting your quinine treatment based on your current health status and any side effects you are experiencing.

3. Symptom Monitoring: Keep a detailed record of any symptoms you experience, including their frequency and severity. This information will be valuable for your healthcare provider in making informed decisions about your treatment.

4. Consultation: If you have concerns about the side effects or the necessity of continuing quinine, don’t hesitate to seek a second opinion or consult a specialist in infectious diseases or hematology.


Conclusion
In summary, while blood tests are essential for monitoring your health and determining the appropriateness of quinine treatment, it’s crucial to maintain open communication with your healthcare provider. They can guide you through the process, ensuring that your treatment is both safe and effective. Always prioritize your health by seeking professional advice before making any changes to your medication or treatment plan.
