Understanding Metronidazole and Trazodone Interaction

3/22/2025, 5:30:20 PMMale25-34

Greetings. I am a 37-year-old woman who recently received a prescription for Metronidazole. My doctor advised me against consuming alcohol during the treatment and recommended I refrain from drinking it for three days after completing my medication. Additionally, she informed me not to use melatonin, but there was no mention of Trazodone in our discussion. Currently, I am taking 500mg of Metronidazole twice daily and 50mg of Trazodone each night to help with insomnia. Concerned about potential interactions, I conducted some research and found out that there might be a risk involved, particularly an increased likelihood of experiencing irregular heart rhythms. I would appreciate any clarification on this matter. If there is indeed a significant risk, could anyone suggest over-the-counter sleep aids that would be safe to use? Thank you for your assistance!

It's great that you're taking the time to understand your medications and their interactions. Here’s the essential information regarding Metronidazole, Trazodone, and their potential interactions.

Main Points:

  1. Metronidazole and Trazodone Interaction: There is a reduced risk of serious interactions, but caution is advised, especially regarding heart health.
  2. Safe Sleep Aids: If seeking alternatives for sleep aids, there are options to consider.

Explanation:

Metronidazole is an antibiotic that has specific guidelines regarding alcohol consumption due to potential side effects, such as nausea and flushing. Trazodone is an antidepressant often prescribed for insomnia, generally considered safe to take with Metronidazole. However, both medications can affect heart rhythms, hence your concern about irregular heartbeats is valid.

While substantial interactions between these two medications are not routinely noted, it's important to monitor your body’s responses when taking both, especially since you're already managing insomnia with Trazodone.

Next Steps:

  1. Monitor Symptoms: Pay attention to any unusual symptoms, such as dizziness, irregular heartbeats, or increased sedation. If you notice anything alarming, consider adjusting your medication with your doctor.

  2. Continue with Caution: Follow your doctor's instructions regarding alcohol consumption and keep an eye on any potential side effects from either medication.

  3. Consider Over-the-Counter Options: If you want a sleep aid that is generally considered safe with Trazodone and Metronidazole, you might explore:

    • Diphenhydramine (e.g., Benadryl): An antihistamine with sedative effects.
    • Doxylamine (found in products like Unisom): Another antihistamine suitable for occasional use.

    Note: Consult with a pharmacist about any over-the-counter medication, as they can offer advice based on your specific circumstances and current medications.

Is a Burning Sensation from Mouthwash Common?

I've recently been using a mint-flavored mouthwash, specifically Crest's teeth whitening formula. However, it caused significant discomfort, stinging my lips and tongue to the point where I felt compelled to switch to Therabreath. Additionally, I had come across information suggesting that teeth whitening mouthwashes might harm your enamel. Therabreath also contains fluoride and mint, and while it still causes some burning, it's noticeably more tolerable than the previous brand. For a long time, I assumed this burning sensation was simply a normal part of using mouthwash, as I have experienced similar discomfort during dental visits throughout my life. To manage the sting from Therabreath, I've found that spitting it out before the pain becomes too intense has been a helpful strategy since it's not quite as severe. At this point, I am uncertain if my reaction is specific to mint or another ingredient present in the mouthwash. I have always disliked using mouthwash due to the discomfort it brings, but Therabreath is just tolerable enough that I keep using it. I'm turning to Reddit for advice first, as I would prefer not to visit my doctor only to be told that this sensation is typical and thus wasting her time. Being autistic, I sometimes find certain sensory experiences overwhelming, and it’s possible that I could just be particularly sensitive in this case.

Experiencing Unexpected Breathlessness One Month After Gallbladder Surgery – Should I Worry?

A 26-year-old woman, weighing 44 kilograms and standing at 5 feet 4 inches, does not smoke or drink. A month has passed since I underwent laparoscopic gallbladder removal, and while my recovery has generally been smooth, I've faced some bouts of fatigue. However, today I encountered something alarming: I felt a sudden shortness of breath after ascending a flight of stairs, which struck me as unusual. Later, while trying on outfits for an upcoming event, the same thing happened again—I became breathless. After some online research, I stumbled upon information regarding pulmonary embolism, which left me feeling quite frightened. Could this be a serious issue? Should I consider consulting my surgeon for further advice?

Struggles with Sleep Due to Flu/COVID

Caution: This message may not be well-articulated as I am running on little to no sleep. I’m an 18-year-old male, currently weighing around 175 pounds, down from 185 before falling ill. For the past four days, I have been dealing with what I suspect is either the flu or COVID-19. I’ve been taking aspirin, ibuprofen, and both daytime and nighttime cold and flu medications. Generally, these have worked for me, save for one incident where I vomited the flu medicine shortly after taking it. Fortunately, I managed to have my lunch, a small bowl of honey yogurt, without issues. My main symptoms include heavy congestion, a sore throat, persistent headaches, and overwhelming fatigue. However, I face a significant challenge: I cannot fall asleep at night. Yesterday, I tried staying awake throughout the day, believing it might help me rest at night, but I ended up unable to sleep then as well. I feel utterly drained, and even simple activities like walking are a struggle. Yet, when I try to rest, sleep eludes me completely.

What Could Be Causing These Symptoms?

I’m a 17-year-old female, standing 5 feet 9 inches tall and weighing 238 pounds. I’m not on any medications, have never smoked, and aside from some broken bones in the past, I don't have any significant health problems. Lately, for the last five days, I’ve been experiencing some unusual urinary symptoms. Each morning, when I go to the restroom, I feel a burning sensation during urination, and it has a strange odor reminiscent of cooked shrimp—definitely odd, right? Furthermore, my urine appears cloudy during this time. However, after I get through that first morning urination, I feel much better; the rest of the day my urine is almost completely clear, free of odor, and pain doesn't accompany it. I assure you, I still have the urge and the need to go frequently—I’m not just feeling the need without actually going. This is entirely new to me, as I’ve never experienced a urinary tract infection before or anything remotely similar. Additionally, I’ve never been sexually active, although I do own a rabbit vibrator that I meticulously clean after each use. Yesterday, I saw a doctor who had me provide a urine sample for testing. Fortunately, the results came back normal. They offered me antibiotics, although they suggested they might not be necessary. I chose to decline the antibiotics since the discomfort isn’t unbearable, but it does have me worried. The doctor plans to send the sample to a lab for further analysis to check for bacterial growth. I’m reaching out to see if anyone might have insights on what could be going on with me. I’d greatly appreciate any advice, reassurance, or explanations of what I might be dealing with. Please feel free to ask me any additional questions; I just want some clarity and support during this anxious time!

Struggling with Sleep

I’m unable to fall asleep. It's been a full 24 hours since I last rested, yet I feel okay. The last time I was in this situation, the feeling of well-being was short-lived; soon I began to hear laughter that seemed directed at me, and I noticed these bizarre insects everywhere, both crawling and flying around. People around me started to get frustrated with my unusual behavior. I can’t recall much from that time, but I felt utterly exhausted. My lips even began to take on a purplish hue, possibly due to sleep deprivation. How can I manage to get some sleep? In the past when I couldn’t sleep, I felt quite good initially, and I suppose I'm somewhat okay now, but it feels insincere, and eventually, I would spiral into exhaustion and disdain for everyone and everything around me. What options do I have to help me sleep? Perhaps medication? I should mention, I’m 17 years old and weigh about 90 pounds.
