Using Quinine for Malaria Prevention: Seeking Guidance
Residing in Southeast Asia, I’m planning a trip to an area where there is some potential for malaria risk, though the level of danger varies according to different sources. During a visit to a local pharmacy, a doctor provided me with 48 tablets of quinine sulfate, each containing 200mg. Upon returning home, I had to translate the instructions and discovered that the label recommends taking two tablets each night while in a malaria-prone region, followed by additional use "for a time afterwards." My trip is just six days away, and I’ll be there for eight days. If I consume two tablets nightly, I’ll have enough left for an additional 16 days after returning home. Most recommendations I've come across suggest starting malaria medication one or two days prior to exposure and continuing it for a week post-visit. However, if I follow this guideline, I will still have seven days of medication remaining. Should I begin taking the quinine sooner and continue until they are finished? I also came across information indicating that excessive quinine use can lead to adverse effects. Moreover, I discovered that quinine is no longer favored as a malaria prevention strategy, yet the packaging distinctly outlines instructions for both preventing and treating malaria. Since I already possess the tablets and cannot return them, I am seeking advice on the best course of action.

It's great that you're taking precautions for your upcoming trip to a malaria-prone area. You're right to be cautious with quinine, as it is not typically recommended as a first-line option for malaria prevention due to potential side effects and the emergence of more effective alternatives.
Main Points:
- Quinine is not the preferred choice for malaria prevention.
- Taking quinine prior to the trip can increase risk of side effects.
- Adhere to established guidelines for malaria prevention.
Explanation:
Quinine is primarily used to treat existing malaria infections rather than prevent them. Modern malaria prophylaxis includes medications like atovaquone-proguanil (Malarone), doxycycline, or mefloquine, which are more effective and have a better safety profile. While your doctor provided quinine with specific instructions, the potential risks of side effects such as tinnitus, headaches, and gastrointestinal issues can increase with inappropriate usage.
Starting quinine before your trip, especially well before you enter a malaria risk area, could lead to unnecessary side effects without additional benefit to malaria prevention. The guidelines you mentioned are generally correct—beginning preventive medication one to two days prior and continuing for seven days after return is standard practice.
Next Steps:
-
Do Not Start Taking Quinine Early: It's best to take quinine only if you actually develop symptoms of malaria after potential exposure. The recommendation for treatment would be based on a clear diagnosis of malaria, not preventive use.
-
Monitor Symptoms: Pay attention to any signs of malaria, such as fever, chills, sweats, headache, or body aches after your trip. If you notice any symptoms, seek medical advice promptly.
-
Consult Local Resources: Reach out to a healthcare provider or a travel clinic for personalized advice on malaria prevention specific to your travel destination. They can provide you with information on effective prophylactic medications based on current guidelines.
-
Stay Protected: In addition to medication, use preventive measures such as wearing long sleeves, using insect repellent, and sleeping under a mosquito net during your stay.
If you have any further questions or need clarification on anything else, feel free to ask. Your health and safety are the top priority!

Concern Over Possible Botulism Exposure: Seeking Guidance
Greetings, everyone! I'm a 37-year-old male, weighing approximately 80 kilograms and standing at about 1.75 meters tall. To provide some context, I'm currently visiting a friend in another country, but I don’t have any travel health insurance. My friend had to work through the weekend and encouraged me to help myself to whatever food I found in her refrigerator. Upon arriving, I discovered some gravy that appeared and smelled fine. I decided to prepare some frozen fries in the oven while simultaneously heating the gravy in a dish, which I placed in the oven at a temperature of around 225 degrees Celsius. Following the instructions, I set a timer for 20 minutes when cooking the fries. However, when the timer went off, the fries didn’t seem fully cooked. I opted to give them an additional 10 to 15 minutes to bake (the gravy was still on the bottom, and I had completely forgotten about it). Eventually, the fries emerged from the oven, slightly overdone, but I didn't mind. Upon pulling everything out, I noticed that the gravy had begun to burn and char during the process. Afterward, I proceeded to eat the fries along with some of the gravy, which had turned into a paste-like consistency. I later called my friend to catch up and mention what I had for dinner. To my dismay, she panicked when I mentioned the gravy, informing me that it was actually 12 days old and stored in a plastic container. Now I’m left worried about my situation. How serious is this? To provide additional context: - It’s been 12 hours since I consumed the food, and I have not yet experienced any symptoms. What signs should I be vigilant for? - I heated the gravy thoroughly; it was in the oven for over 30 minutes, and the edges of the plate were charred. - Prior to this meal, I hadn't eaten anything for nearly 24 hours, so I'm hoping my stomach's acidity might be a protective factor. I didn't consume a large amount, discarding approximately half of what I had. I would greatly appreciate any advice or insights regarding this situation.
Rash on the Dorsal Side of My Hands
A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?
Understanding Foam in Urine: When is it a Concern?
Age 24, I've observed a notable increase in the amount of foam in my urine over the past couple of years, compared to what I remember from before. About a year ago, I mentioned this to my primary care physician, who seemed somewhat dismissive of my concerns. Nonetheless, they proceeded to conduct a urinalysis, which returned normal results, indicating no elevated protein levels. I frequently undergo blood tests, and both my eGFR and creatinine levels typically fall within the normal range, although I did experience some fluctuations linked to a bout of mononucleosis a couple of years back, where my eGFR dipped near 70; it currently remains above 100. I suspect that changes in my urological function, likely from aging, are contributing to a stronger urine stream now than in my youth. The foam generally settles down after a few minutes, although occasionally it lingers longer than expected. I make a concerted effort to stay hydrated, even though I don’t always succeed, so I wonder if mild dehydration could partially account for the foaming. This concern is particularly relevant as I'm resuming strength training and planning to increase my protein consumption. I want to ensure that my kidneys are not overtaxed due to any potential underlying issues. Additionally, I have a history of taking 5 grams of creatine daily, paired with plenty of water, which makes me cautious about this, too. Is there a point at which foaming in urine is considered excessive, or does a specific threshold exist that I should be aware of?
Understanding Symptoms of Salmonella: What to Do Next
My boyfriend, who is 26, experienced a fever that peaked at approximately 99.5°F yesterday morning. Thankfully, after resting and taking NyQuil, his fever subsided by this morning. However, he has been dealing with severe abdominal pain and persistent diarrhea since last evening, which has not shown much improvement. He has been making frequent trips to the restroom, nearly every hour throughout the night and again today. While I initially thought he might be improving since the fever has decreased, I became alarmed upon noticing bright red blood in his stool and on the toilet paper after he wipes. It has been around 40 hours since the fever began, and my concern has heightened now that blood has appeared. I’ve come across some online information suggesting these symptoms might be typical for salmonella infections, and I’m uncertain whether we should seek medical attention immediately or if it’s advisable to wait another day or two to see if his condition improves. I realize that consulting a doctor as soon as possible would be the best course of action. However, he currently lacks insurance, which makes him hesitant to get checked right away. Any guidance on this matter would be greatly appreciated, thank you.
Navigating Alcohol Challenges
My partner has recently developed issues with alcohol. Over the past year, he has been consuming significant amounts—roughly two bottles of distilled spirits each week, in addition to beer. A decade ago, he struggled with inhalants and even faced near-fatal consequences, but he had maintained sobriety until he turned to drinking. He believes he has plenty of time before the effects of alcohol will manifest. How long can he continue this way before it becomes a serious problem? He is a 53-year-old male, weighing 325 pounds, standing at 5 feet 11 inches, and he is currently on medication for hypertension. Although we plan to separate later this year, it’s clear that this situation will have an impact on our three children.
