Evaluating the Long-Term Safety of Using Sertraline with Fluconazole
Greetings everyone, I’m a 23-year-old woman currently prescribed sertraline to manage depression and anxiety. My healthcare provider has recommended fluconazole to address some fungal issues. The intended plan is to start with a daily dose of 100 mg for the first two weeks, followed by a reduced maintenance dose of 50 mg each day for the subsequent 20 weeks. I’ve come across some information indicating that fluconazole may exert strain on the liver and has the potential to extend the QT interval. Given that sertraline also undergoes liver metabolism and can impact the QT interval, I have concerns about the safety of using these medications together over an extended period. I’d like to pose a few questions: - Has anyone experience combining sertraline with fluconazole for an extended duration? - Is this pairing safe, or does it warrant regular liver function assessments and electrocardiograms (ECGs)? - What type of monitoring is generally advisable in this scenario? Thank you in advance for your helpful perspectives! 🙏

Combining sertraline and fluconazole can be done safely, but it requires careful monitoring due to concerns about liver function and heart health. Here’s what you need to know:
Key Points:
- Potential Interactions: Both sertraline and fluconazole are metabolized by the liver and can affect heart rhythm (QT interval).
- Monitoring Recommendations: Regular liver function tests and possibly heart rhythm assessments may be advised due to the use of these medications together.
- Personalized Monitoring: The level of monitoring may depend on your individual risk factors and overall health.
Explanation:
-
Liver Function: Both medications can put stress on the liver, especially if you have a pre-existing condition or if other medications are involved. It's essential to monitor liver function tests (like AST, ALT) periodically to ensure your liver is healthy while on these drugs.
-
QT Interval: The QT interval is the time it takes for your heart to recharge after beating. Both sertraline and fluconazole have the potential to prolong this interval, which could lead to dangerous heart rhythms in some individuals. ECGs may be recommended if you're at higher risk (such as having a history of heart problems).
Next Steps:
-
Discuss With Your Healthcare Provider: Make sure to communicate your concerns with your provider. They may choose to monitor your liver function and heart rhythm more closely, especially in the beginning.
-
Regular Monitoring: If starting this combination therapy, expect to have liver function tests done approximately every 4-6 weeks initially, or as recommended based on your health history.
-
Watch for Symptoms: Pay attention to any unusual symptoms like fatigue, jaundice (yellowing of skin/eyes), heart palpitations, or irregular heartbeat. Report these immediately to your healthcare provider.
-
Educate Yourself: Stay informed about both medications, their side effects, and potential interactions. This knowledge can empower you in discussions with your healthcare team regarding your treatment plan.
Your concerns are valid, and with proper monitoring, many individuals successfully use these medications together. Don’t hesitate to reach out for clarifications or more personalized advice as you continue your treatment.

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
