Managing Failed Intramuscular Injections: What to Do with Prefilled Syringes
Hello everyone. I use intramuscular injections which are conveniently preloaded in syringes. I have been instructed to retract the plunger before proceeding to ensure I haven’t entered a blood vessel. Last Saturday, while following this guidance, I noticed blood. I decided to switch to a different area, but just as I did, my cat unexpectedly jumped against my TV, which startled me and caused me to hastily remove the syringe from my arm. I've come across information indicating that reusing a syringe in this scenario could be detrimental. Each insertion can dull the needle and potentially cause micro-tears in the tissue, heightening the risk of infection. I am cautious and would prefer to avoid complications, but I was only able to administer half of my dose. Given that these injections are costly, priced at around $100 each, I feel reluctant to waste any medication. Is it advisable to attempt a second injection at a different site under these circumstances, or does that pose too great a risk?

It sounds like you're handling a challenging situation with your intramuscular injections. Your concern about waste and the risk of complications is understandable. Here’s how to approach this safely:
Main Points:
- Do Not Reuse the Syringe: It's crucial to avoid injecting with a previously used syringe as this can increase the risk of infection, especially with intramuscular injections.
- Consider a New Injection: Given that you've only administered half of your dose, using a new, sterile syringe for a second injection could be necessary to ensure you receive your full medication.
- Monitor the Injection Sites: After your next injection, keep an eye on both injection sites for any unusual symptoms.
Explanation:
When you noticed blood after retracting the plunger, it indicated that you may have hit a blood vessel. This is a common occurrence and switching sites was a sensible decision. However, you should not attempt to reuse the same syringe after any discomfort or unexpected movement, as it could lead to microtears or infection risks.
It's also important to fully administer your medication to achieve the desired therapeutic effect, especially if the injections are critical for your health.
Next Steps:
-
Prepare for a New Injection:
- Choose a clean, different injection site from where you previously injected.
- Use a new, pre-filled syringe to avoid any infection risks or complications.
-
Injection Technique:
- Ensure you clean the injection site with an alcohol wipe to reduce the risk of infection.
- Inject slowly and steadily, ensuring your technique is as calm as possible to avoid mistakes.
-
Monitor Your Body:
- After the injection, watch for any signs of infection at the injection sites like redness, swelling, or increased pain.
- If you experience unusual symptoms, seek appropriate help.
-
Consider Future Doses:
- If you're worried about costs and medication waste in the future, discuss with your healthcare provider about your options, including the possibility of using auto-injectors or alternative therapies if available.
Prioritize safety and effective administration of your medication. If you have any further concerns or complications arise, don’t hesitate to ask for further guidance.

Seeking Clarity on Breathing Issues
Profile: Male, 25 years old, 6 feet tall, weighing 200 pounds, Caucasian, located in the USA. Medications/Vitamins: Aside from occasional over-the-counter medications, I take nothing. Since experiencing Covid in 2020, I have struggled with shortness of breath. Despite undergoing pulmonary function tests (PFT) and CT scans that have returned completely normal results, I still find my breathing is not what it used to be. Before my illness, I consumed approximately three packs of cigarettes throughout my life and used marijuana frequently. During the weeks I was ill, I sensed a significant decline in my lung capacity, which hasn’t improved even with the normal test outcomes. The only anomalies I have observed are an elevated heart rate, occasional increases in my red blood cell (RBC) count according to blood tests, alongside persistent difficulty in breathing. Could there be another factor contributing to these symptoms? Is it possible that my lungs are actually functioning well and that the issue lies elsewhere in my body? Could there have been a misinterpretation of my PFT results? What other factors might contribute to an increased RBC count?
Colorful Eye Floaters: An Unusual Experience
I’m a 44-year-old male currently managing my hypertension with a regimen of 5mg of Bystolic and 160mg of Diovan, along with an occasional multivitamin. I have maintained sobriety for five years, weigh 175 pounds, and stand 5'7" tall. Although I consume a lot of coffee, I find myself not drinking enough water. This peculiar occurrence has happened twice within a three-month span. While at work, I noticed a rather unusual sensation in my eye, reminiscent of the common "floaters" that many experience. However, unlike typical floaters that are transparent, this one was vibrant—displaying a rainbow of colors akin to a fresh oil slick on asphalt. It also morphed slightly, maintaining the general shape of a floater throughout. It seemed to occupy approximately one-eighth of my field of vision. After about twenty minutes, it gradually drifted towards my peripheral view before vanishing entirely. Interestingly, I could still perceive it with one eye closed, suggesting that it impacted both eyes. Aside from mild irritation and some anxiety regarding the situation, no other symptoms were present. This led me to ponder if this could potentially be the "strobe" or "zigzag" aura often experienced before migraines. Though I experienced TMJ-related problems between 2010 and 2013, those migraines were devoid of any aura. Additionally, I had encountered a minor retinal hemorrhage about five years ago, which resolved itself within a fortnight. I was concerned that this recent incident might be a recurrence—yet, that episode presented as "white hot,” distinctly different from the colorful display this time, and it did not behave in the same manner. Since then, my blood pressure has stabilized well due to my medication regimen.
Experiencing Disturbances in My Vision
I've been encountering something unusual in my peripheral vision on the right side. This occurrence seems to strike at random intervals. Initially, my right eye experiences an odd sensation, which persists even when I shut that eye—it's as if something is tracking along with my gaze. This sensation tends to dominate my visual field, and its nature is puzzling to me. Generally, a good night's sleep alleviates the problem, but I'm uncertain about what might be causing these disturbances. Accompanying this visual anomaly is an intense headache that surfaces shortly thereafter, which escalates quickly to a level that renders me unable to function, often resulting in vomiting and forcing me to stay in bed. Could there be a medical explanation for what I’m experiencing? I’ve previously consulted a doctor about this issue, but the outcome was unhelpful, so I thought I'd seek insights here before contemplating a hospital visit. I'm uncertain if I'm truly unwell since over-the-counter pain relievers and migraine medications seldom provide relief. For context, I am a teenager, aged between 12 and 18. Interestingly, bright flashing lights do not appear to trigger this condition. However, I’ve discovered that staying well-hydrated and practicing slow, deep breathing while shielding my eyes with something dark often helps alleviate the symptoms. I would appreciate it if you could refrain from asking personal questions regarding my home life, school, or daily routines, unless they are directly relevant to my health concerns. I prefer to maintain a level of privacy online and am uncomfortable sharing personal details like my voice or appearance with others, including friends from school.
Is That a Bump on the Eye?
This morning, my father-in-law discovered a yellowish-pink bump on his eyeball. At the age of 67, he's naturally concerned. We attempted to visit a Target optometrist, but they informed us that they do not handle medical concerns and refused to examine it. Since he is unable to secure an appointment with an optometrist for several days, he asked me to share some images here for insight. Does anyone have an idea of what this might be or how pressing the situation could be?
Seeking Advice on Ear Drops for Congestion-Related Infection
I am a 32-year-old male, standing 6 feet tall and weighing 295 pounds, with a known allergy to Zithromax. Recently, I've come down with a cold that began two days ago. By yesterday, I noticed that my right ear was blocked due to congestion, and today, I’m experiencing some discomfort inside it. This isn't the first time this has happened—these types of ear issues occur about once a year for me. In the past, I've usually been prescribed oral antibiotics, which have effectively resolved the issue. As a child, I faced frequent ear infections and had to undergo procedures like getting tubes in my ears. To address my current situation, I utilized an e-health service called MDLive, where I detailed my symptoms for a medical professional to evaluate. The physician recommended a prescription for Ciprodex ear drops, which I’ve never used before. This recommendation seems a bit unusual to me—can ear drops effectively treat an ear infection that stems from congestion? Is this a common approach to such a condition? I plan to get the prescription filled and start using the drops, but I’m contemplating whether I should also consult my primary care physician for additional advice. I hesitate to reach out unnecessarily. Any insights would be appreciated!
