Experiencing Side Effects from Phentermine

3/18/2025, 8:20:33 AMMale25-34

After receiving a prescription for phentermine to support my weight loss journey, I encountered some alarming symptoms. By the 23rd day of using the medication, I noticed my heart rate skyrocketed from the 70s to 140 beats per minute, persisting for around five hours following exercise. Concerned about this spike, I sought medical attention at the emergency room, where they assured me that apart from the elevated heart rate, everything appeared normal. Despite my physician's reassurance that it was safe to continue taking phentermine, I decided to discontinue its use. Fast forward more than a month, I'm now experiencing intermittent back and chest discomfort. Additionally, my hands have been feeling unusually cold, and I've observed that the pads of my left fingers resemble the texture of a prune. I returned to the ER this week, and once again, I received the same feedback—everything looked fine from their perspective. Has anyone else gone through a similar experience? Did your symptoms improve over time?

It's understandable to feel concerned about the symptoms you're experiencing after taking phentermine, especially with the elevated heart rate and subsequent discomfort. While it's reassuring that your medical evaluations showed no immediate danger, your ongoing symptoms warrant careful attention.

Main Points:

  1. Elevated heart rate is a recognized side effect of phentermine.
  2. Your current symptoms, including chest and back discomfort and cold hands, may not be directly related to phentermine now that you have stopped it.
  3. Monitoring your symptoms and making lifestyle adjustments can help.

Explanation:

Phentermine is a stimulant that can increase heart rate and blood pressure, which might explain the spikes you experienced during its use. The symptoms you're describing now (intermittent chest and back discomfort, cold hands, and changes in finger texture) could potentially be related to stress, anxiety, or circulation issues but might not be linked to phentermine if you've discontinued it.

Next Steps:

  1. Symptom Monitoring: Keep a daily record of your symptoms—note when they occur, how long they last, and any patterns you observe. This can help identify triggers or connections.

  2. Hydration and Nutrition: Ensure you are drinking enough water and eating a balanced diet rich in nutrients. Staying hydrated can help support circulation, and a balanced diet can improve overall wellness.

  3. Gentle Exercise: If you haven't done so already, gently reintroducing light exercise like walking or stretching can improve circulation and stress management. Avoid high-intensity workouts until you feel more stable.

  4. Review Stress Management: Engage in relaxation techniques such as deep breathing exercises, meditation, or yoga, which can help alleviate anxiety and may reduce physiological symptoms.

  5. Follow-Up Care: If your symptoms persist or worsen, consider keeping a follow-up appointment with your primary care provider. Discuss all your concerns, including the cold hands and chest discomfort, and ask for a thorough evaluation, or ask them if further testing is appropriate (such as cardiovascular assessment).

Remember, it’s important to prioritize your health and comfort. If you’re ever in doubt or feel worse, seeking medical attention is always the right choice. Be gentle with yourself during this time, and focus on gradual improvements.

Is an 85-pound Weight Healthy for a Woman Who is 5’1"?

A friend of mine stands at 5 feet 1 inch tall and has a delicate frame, tipping the scales at 85 pounds. At first glance, her weight seemed surprisingly low, but I realized she doesn’t appear overly thin. Naturally, I became a bit worried as I believed her weight might be below the healthy range; however, she insists that she feels perfectly fine. She maintains an active lifestyle, exercising regularly and following a nutritious diet, yet she doesn't overindulge. This leaves me pondering whether her health is indeed in check.

Persistent Need to Stretch Legs While Seated

I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.

Combining Ketorolac with Alcohol: Is It Safe?

Recently, I unknowingly mixed a 10mg dose of ketorolac with half a bottle of 4.5% beer. At that moment, I wasn't aware of the potential risks involved in this combination. It wasn't until I was partway through my drink that I thought to look it up. Now, I’m wondering if it’ll be fine for me to have a drink tomorrow night after stopping all ketorolac use, especially since this medication hasn’t been effective for my pain relief. To give you an idea of the timeline, I took ketorolac around 2 PM and didn’t start drinking until 11 PM.

Struggling to Increase My Weight

At 5 feet 7 inches tall and weighing 130 pounds, I’m a 17-year-old male who has been grappling with weight gain for the past year and a half. Despite my efforts, I’ve only managed to add 10 pounds during that time. My daily caloric intake sits between 1,500 to 2,000 calories, yet I find it challenging to consume more than that without feeling nauseous. I work out regularly, hitting the gym approximately three to four times each week, and I also engage in a lot of basketball. Despite my dedication, I feel like my strategies for gaining weight simply aren't effective. What would be the most straightforward and quickest way for me to pack on some extra pounds?
