Assessing Headaches: Side Effects from Pristiq or Withdrawal from Effexor?
A 43-year-old female with a medical history that includes depression, anxiety, hypertension, and a cancer diagnosis of invasive ductal carcinoma staged I on 10/2/24, underwent surgery (DMX) on 12/10/24. She is currently on various medications, including Leuprorelin every three months beginning 1/10/25, along with Buspar (30mg three times daily), Olmasartan (20mg daily), Spironolactone (75mg daily), Semaglutide (0.5mg weekly), Docusate (50mg daily), Senna (8.6mg daily), Melatonin (2.5mg daily), and Pristiq (50mg daily). Tamoxifen treatment was also involved and ceased on 3/10 when transitioning to Leuprorelin. Currently, she is experiencing significant headaches accompanied by cognitive difficulties, commonly described as brain fog. Symptoms include difficulty concentrating, a sensation of moving text while reading, and impeded thought processes. Common pain relievers such as Tylenol, ibuprofen, naproxen, and caffeine have been ineffective, contributing to a feeling of disconnect from her usual self. Initially, her depression and anxiety were well-managed on Effexor XR at a dosage of 150mg until a cancer diagnosis in October 2023 prompted a dosage increase to 225mg in December. The problematic symptoms persisted, especially with anxiety impacting her work performance and sleep quality. Consequently, after consulting her primary care physician (PCP) on February 26, she switched to 100mg of Pristiq, under the impression that a direct switch from Effexor would require no tapering. On March 10, she noticed the onset of a headache that did not respond to her usual pain relief methods. Despite not frequently experiencing headaches, she disregarded it initially; however, by March 15, another unresponsive headache appeared, and she has since endured a persistent debilitating headache daily. Seeking a solution, she consulted her PCP on March 21, who suggested that the headaches might be a side effect of Pristiq. A new medication regimen is to be implemented: 50mg of Pristiq daily for one week, then alternating doses for another week, followed by starting Lexapro at 5mg and increasing to 10mg. After taking her first 50mg Pristiq dose on March 22, she experienced similar symptoms but reported feeling better the following day, with a regular headache that subsided with naproxen, allowing her to engage in family activities. However, she notes a return of her headaches and brain fog over the past two days. She's seeking insights from other healthcare professionals regarding the potential causes of her headaches: Is it genuinely a side effect of Pristiq, a withdrawal from Effexor (another possibility her PCP mentioned), hormonal changes due to recent medical menopause, or some other factor? Additionally, she is looking for recommendations on effective pain relief methods. Your input would be greatly appreciated!

It sounds like you're dealing with a complex set of symptoms that could be attributed to multiple factors, including medications, recent hormonal changes, and your underlying health conditions. Here’s a summary of the key points and some steps you can take to manage these headaches and cognitive difficulties.
Main Points
- Potential Causes of Headaches: These may stem from side effects of Pristiq, withdrawal from Effexor, hormonal changes from treatment, or stress related to your current health situation.
- Cognitive Difficulties: The brain fog and concentration issues are likely linked to the headaches and could be enhanced by both medication and hormonal adjustments.
- Effective Pain Relief: Current pain relief methods have been ineffective, so exploring alternatives or adjuncts is crucial.
Explanation
- Medication Transitions: Switching from Effexor to Pristiq, especially without tapering, can sometimes lead to withdrawal symptoms, including headaches. Similarly, moving into menopause due to treatment can contribute to headaches as well.
- Headaches as Side Effects: Some people experience headaches as a side effect of certain antidepressants. Pristiq can cause headaches in some individuals, particularly when starting or adjusting dosages.
- Hormonal Changes: Tamoxifen and Leuprorelin can trigger changes in your hormonal balance, leading to headaches as well.
Next Steps
-
Track Your Symptoms: Keep a detailed diary of your headaches and any other symptoms, noting when they occur, their intensity, duration, and any potential triggers (diet, stress, etc.). This information will help your healthcare providers understand what you’re experiencing.
-
Adjunct Pain Relief Strategies:
- Hydration: Make sure you are adequately hydrated, as dehydration can worsen headache symptoms.
- Dietary Modifications: Avoid known headache triggers such as aged cheese, processed meats, caffeine (if inconsistent in consumption), and alcohol.
- Relaxation Techniques: Incorporate relaxation exercises like deep breathing, mindfulness, or gentle yoga to help manage stress, which may be contributing to your symptoms.
- Regular Sleep: Aim for a consistent sleep schedule, as poor sleep can exacerbate headaches and cognitive difficulties.
-
Re-evaluate Medications: Continue to work closely with your healthcare providers as you adjust to Pristiq and transition to Lexapro. If headaches persist, alternative medications or dosages may be required.
-
Consider Non-Medication Approaches: Techniques like acupuncture, biofeedback, or cognitive behavioral therapy (CBT) may provide relief and are often beneficial for headache management.
-
Follow-Up: Schedule regular check-ins with your healthcare provider to discuss the effectiveness of the new medication regimen and symptom progression.
Your experience is valid, and seeking clarity on these symptoms is essential. You are navigating significant treatments and changes, and it’s important to prioritize self-care and communication with your healthcare team.

Understanding the Impact of Increased Fiber on Stool Shape
It might seem contradictory to some, as we typically hear that fiber contributes to bulkier stools. However, I’ve noticed that when I increase my fiber intake, it seems to lead to a quicker transit time, resulting in flatter stools. Interestingly, once I reduce my fiber consumption, the stool shape returns to its usual form. What could be the reason behind this phenomenon? Is it possible that it’s related to a sensitivity to fiber or perhaps a sudden surge in foods high in fiber, including drinks with psyllium husk?
Significant Bloating Following General Anesthesia
It has been just over a day since I underwent general anesthesia, and I currently feel as if I’m six months along in pregnancy. Despite only having a little food during this period, I am experiencing considerable discomfort, akin to having indulged in three feast meals! As a healthy 47-year-old woman who is not on any other medications, I underwent a dental implant procedure that was free of complications and did not require any pain relief medication afterwards. Could this sensation be attributed to gas, and if so, what could be causing it? How long might this discomfort persist? I have come across suggestions that using heat, peppermint, and engaging in walking or stretching may alleviate the situation. Are there any additional remedies or strategies that could provide relief?
Chronic Leg Discomfort Since Childhood
I am a 14-year-old female who has experienced persistent discomfort in my legs for as long as I can recall, and the cause remains unclear. The maximum duration I can manage to walk without feeling faint is around 10 minutes, while I can only walk for about 5 minutes without needing to pause. Even when I’m at rest, I feel a dull ache in my legs, despite the rest of my body feeling relaxed. This discomfort predominantly occurs around my joints, particularly my knees and ankles, although my calves also become tender with minimal exertion. My feet tend to be perpetually cold, rarely warming up even when the rest of my body does. During my menstrual periods, I find it extremely difficult to walk, often having to hold onto walls just to navigate short distances. I've always maintained a healthy weight and I don't consider myself unhealthy overall. The only medical condition I’ve been officially diagnosed with is autism, although I'm unsure if this has any relevance to my symptoms.
Seeking Help for My 5-Year-Old Son with Autism and Constipation Issues
Hello, I am reaching out regarding my 5-year-old son who is non-verbal and has autism. He also shows signs of ADHD, although this has not yet been officially diagnosed. Typically, he is very energetic, cheerful, and expressive. He thrives in his school environment, where he is supported by a wonderful team of special education teachers. He doesn’t take any regular medications, except for melatonin to assist with his sleep. Recently, on December 19th, he developed a rash while at school, which resembled hives on his neck, face, and feet, with accompanying swelling in his hands. By the time we went to urgent care, the rash had disappeared, and he was given Benadryl. Unfortunately, the rash recurred a couple of times at home, though we only administered Benadryl on two occasions. Following this, during Christmas break, I noticed he became increasingly emotional, crying daily, appearing more fatigued, and having less energy overall, although he was usually still able to be comforted. I visited the pediatrician twice during this period, and lab tests came back normal, except for a positive COVID-19 result. The doctor prescribed guanfacine and clonidine for him (I apologize if I spelled those incorrectly), but I chose not to give him these medications since they weren't intended for behavioral issues. When school resumed, for the most part, he seemed to manage well until last week when he experienced another rash episode at school, occurring twice. I decided to try a non-drowsy allergy medication for him, but his emotional state deteriorated again, leading him to cry throughout the school day. His teachers expressed concern, stating that he appeared to be in discomfort, which they confirmed is not related to behavioral issues. At home, he has been very upset and inconsolable. As a result, I took him to the hospital yesterday. They sedated him for a head CT and abdominal ultrasound, both of which showed no abnormalities. They prescribed Miralax and suggested looking into ABA therapy since his autism diagnosis may automatically point to behavioral factors, which frustrated me. Today, he has spent the entire day crying and has remained in bed, clearly exhausted. I am administering the Miralax, and he seems visibly uncomfortable, but he hasn't had a bowel movement yet. His last stool was two days ago, and only a tiny amount has come out since then. I’m uncertain if the rash and his current symptoms are related to constipation or if I am missing a more serious issue entirely. This is very distressing. We have a dental appointment scheduled for Tuesday to rule out any dental issues, our fourth visit with the pediatrician on Wednesday, and a phone consultation with an allergist also on Wednesday. I would greatly appreciate any insights or questions I should bring up during our pediatrician visit, as well as any tips or suggestions. I'm feeling quite desperate for help. Thank you!
Unexplained Discomfort
I’m a 45-year-old woman, a non-smoker, weighing 245 pounds. My only medical concerns include acid reflux, allergies, and De Quervain’s syndrome affecting my right wrist. Currently, I’m focused on losing weight and have successfully shed 30 pounds so far. I take a daily regimen of Omeprazole and Zyrtec. I’m attempting to articulate the nature of my discomfort, which has been somewhat challenging. The sensation tends to appear in random areas of my body. At the moment, I feel it in my left arm, but I've also experienced it in my thighs, legs, and hands. This odd sensation occurs irregularly for one to two days, then recedes for a month or even longer before reappearing. The discomfort resembles a mild burning feeling under the skin—a persistent yet not intensely painful sensation. It’s more bothersome than painful, as I am acutely aware of it when it arises. During these episodes, I find it uncomfortable for clothing to touch the affected area, and I often prefer cooler temperatures, which seem to alleviate the sensation. This has been an ongoing issue for about a year now. Has anyone else gone through something similar? I’ve refrained from consulting a physician as it’s difficult to describe, and the discomfort isn't severe or constant enough to warrant medical attention.
