Left My Clonazepam in a Heated Car for a Day – What Should I Do?
Hello, I'm feeling quite anxious at the moment and would really value some guidance. I am a 22-year-old male and have been prescribed .5 mg of clonazepam every 8 hours for nearly three years. Unfortunately, I made a huge mistake today by leaving my medication in a hot car for approximately 24 hours. I'm aware that excessive heat can compromise the effectiveness of medications like this, so I'm uncertain whether it's still safe to take. Should I reach out to my doctor to explain the situation and request a new prescription? Alternatively, would it be better to contact my pharmacy directly? I'm concerned about whether they would be willing to provide a refill for a benzodiazepine like Klonopin. I'm really worried right now and would appreciate any advice you might have on how to handle this situation.

It’s understandable to feel anxious about your medication, especially after it’s been exposed to high heat. Here is how to approach this situation:
Main Points:
- Heat can degrade clonazepam, potentially affecting its potency.
- Contact your doctor or pharmacy for guidance on replacing your medication.
Explanation:
When medications like clonazepam are left in a hot car, the heat can alter their chemical composition, making them less effective or potentially unsafe. As a result, it's important to verify whether your medication is still usable before taking it. Since you've been on this medication for a while, I understand that you rely on it for your well-being.
Next Steps:
-
Do Not Take the Medication: For safety, avoid taking any clonazepam that was left in the heated car until you get clarification.
-
Contact Your Doctor: Reach out to your prescribing doctor as soon as possible to explain the situation. They will advise you on whether you need a new prescription and can assess any other concerns related to your anxiety.
-
Check with the Pharmacy: If your doctor is unavailable, you could call your pharmacy for advice. They may be able to provide options or refill the prescription depending on their policies and your prescription history.
-
Monitor Your Symptoms: In the meantime, if you start feeling anxious, consider using non-pharmacological methods to manage your anxiety, such as deep breathing exercises, mindfulness, or distractions.
Remember, it’s important to keep open communication with your healthcare providers, so they can support you during this time. If you feel that your anxiety is increasing, don’t hesitate to share that with your doctor as well. You're not alone in this, and there are professionals ready to help you through.

Concern Over Swallowed Toys
Today, my four-year-old accidentally swallowed a toy shaped like a grape and another resembling a chicken (I’ve shared some images in the comments).

Uncertain Health Concerns
At 27 years of age, I stand 5'6" and weigh approximately 135 pounds.

Additionally, I've experienced mild discomfort in my lower abdomen. I am generally healthy and have tested negative for sexually transmitted infections.

Should I be significantly concerned or alarmed?
What’s This Small Lump in My Armpit?
Hello, I'm a 16-year-old female with no significant medical issues apart from elevated blood pressure due to stress. About two to three years ago, I discovered a tiny lump in my armpit, roughly the size of a pea, shortly after shaving. It became inflamed when I applied deodorant and caused a bit of soreness, which made me take notice. At that time, I observed a small cyst-like area above it that occasionally discharged fluid, but the lump beneath felt deeper than what I initially thought. After some time, I stopped worrying about it and assumed it was just a benign cyst. Recently, I revisited the site and realized there's no tenderness or visible cyst head noticeable now. I did see a small area that resembles a head but I'm uncertain if it's connected to the lump. The lump doesn't seem very pronounced and feels slightly deep, though it always may have? Locating the lump can be challenging, as it requires quite a bit of pressure for me to detect it. It doesn't shift with minimal touch but does move when I manipulate the skin around it. For the past three years, it's been a non-issue, but I suddenly recalled its presence. Is this something to be concerned about? Should I seek medical advice?
Is My Recent Weight Loss Cause for Concern?
(Age 18, Height 5'2", currently on beta blockers and antihistamines, diagnosed with POTS and hEDS, primarily housebound but engage in daily physiotherapy) Since May, my weight has decreased from 57 kilograms to 53 kilograms by July. To provide some context, I initially aimed to shed a little weight after experiencing a gain attributed to the birth control pill, which I had stopped taking in February due to my absence of menstrual periods. However, after reaching 57 kilograms in April, I essentially ceased my weight loss efforts. Thus, I would classify this recent weight drop as unintentional. My medical professionals have warned me not to lose more than 4 kilograms as my braces are calibrated for a specific weight, adding to my concern. Normally, I monitor my caloric intake closely due to gastrointestinal challenges and my inability to sense hunger accurately. Over the past month, I’ve slacked off in tracking my calories because of an increased workload, but for several years, I have targeted around 1300 calories daily, plus calories from various activities—be it taking a shower, moving around the house, or completing my physiotherapy exercises. While I was gaining weight while on the pill with this calorie allowance, I reached my ideal weight in April without needing to adhere to a strict diet after discontinuing it. In recent months, I believe I've been consuming enough calories—if not slightly more—especially as my appetite has improved. There were a couple of weeks where I managed to eat only about 800 calories a day, but that was a month ago, and I find myself continuing to lose weight even now. Given all of my weight changes, I've never dropped to 53 kilograms since my early teenage years. Should I be concerned about this trend?
