Understanding G6PD Deficiency
Greetings! I'm a 27-year-old man who recently underwent testing for G6PD deficiency. The results indicated a count of 0.3 U/ghb, categorizing me into either a Class 2 or Class 3 deficiency. This classification implies that there are specific medications I must avoid. Additionally, I have a history of severe allergic reactions, particularly to penicillin; I had a serious reaction to amoxicillin. I'm reaching out to determine what medications I can safely be prescribed without complications.

It's important to be cautious with G6PD deficiency, especially regarding medication choices, so I appreciate you reaching out. G6PD deficiency can lead to hemolytic anemia in response to certain medications, foods, and infections, and with your severe allergies to penicillin, we want to prioritize your safety.
Key Points:
- Understanding G6PD Deficiency: A deficiency in G6PD (glucose-6-phosphate dehydrogenase) makes red blood cells vulnerable to destruction under certain stressors, including specific medications.
- Medication Safety: While you will likely need to avoid certain medications, there are many safe options available.
Explanation:
G6PD deficiency is classified into different classes based on enzyme activity, where Class 2 and Class 3 indicate moderate to severe forms, which can lead to hemolytic anemia, particularly when exposed to known triggers. Common medications that should be avoided include certain antibiotics (like sulfonamides), antimalarials (like primaquine), and some pain relievers (like certain NSAIDs). Since you have a known allergy to penicillin, it's also crucial to avoid penicillin and its derivatives.
Next Steps:
-
Create a Medication List: Consult with a pharmacist or a healthcare professional to compile a list of medications that are safe for you to use. Good options may include:
- For Pain Relief: Acetaminophen (Tylenol) is generally safe.
- For Antibiotics: Consider alternatives like macrolides (e.g., azithromycin) or cephalosporins that you are not allergic to. Always double-check with your healthcare provider.
- For Allergies: Antihistamines like loratadine (Claritin) or cetirizine (Zyrtec) may be safe.
-
Discuss with Your Healthcare Provider: Reach out to your doctor to discuss your G6PD deficiency and allergies in detail. They can provide personalized advice and prescribe suitable medications. Always inform any healthcare professional of your G6PD status and allergy history.
-
Stay Informed: Educate yourself about G6PD deficiency. Resources from the CDC or G6PD advocacy groups can offer valuable insights and lists of medications that are commonly safe.
If you have any unique health conditions or further questions about specific medications, feel free to ask! Your health and safety are the top priorities.

Navigating the Search for a New Adult Primary Care Physician
Hello everyone, I’m currently on the hunt for a new adult primary care physician (PCP), but I’m finding the process rather challenging. Many providers I’ve reached out to are either not accepting my insurance or are not taking on new patients. The only appointment I managed to secure is scheduled for several months from now. I’ve been dealing with a chronic health issue, and sadly, my previous PCP has not managed it well. I experience pain daily, and the medications administered by my former doctor have proven ineffective. When I voiced my concerns to him, he indicated that, as a pediatrician, he was limited in his capabilities to assist me further. I have spoken with a handful of potential providers, and while they are willing to accept new patients, they have advised me to contact my insurance to officially switch my PCP before I can move forward with scheduling an initial appointment. This is my first time navigating the search for a doctor independently, so I’m uncertain whether this is standard practice. Why must I inform my insurance company to change my PCP? I find it frustrating that I can’t inquire about appointment availability without being classified as a new patient first, which hinges on the aforementioned insurance switch. Is there a more straightforward approach to address this situation? I typically follow instructions, but I’m hesitant to initiate a PCP change and subsequently face another lengthy wait for an appointment that’s set months away.
Should I Consult a Physician?
I’m a 21-year-old woman who doesn’t consume alcohol but is a smoker. Over the past few months, I’ve been experiencing episodes of dizziness and a sense of lightheadedness each morning. Additionally, my breathing seems to be quite irregular; it feels as though I can’t get a full breath for the first hour after waking up. My boyfriend typically sleeps through the night, so he’s unaware of my breathing issues. Upon inspecting my throat, I’ve noticed significant swelling in my tonsils, which seems to decrease after about one to two hours. I generally get around seven to eight hours of sleep a night and make sure to drink two large cups of water before bed and right after I wake up. Should this be something worth discussing with a healthcare professional?
Elevated Levels of Atypical Lymphocytes (ALY)
A 22-year-old individual presenting with a weight of 55 kg and a body temperature of 97°F has reported experiencing discomfort due to a lymph node situated beneath the neck. Following the administration of medications, including Cefxim 500 mg, Solocold, Montel-D, and Flect, there was a noticeable decrease in the size of the lymph node after just one day. Despite this improvement, the patient continues to experience significant daytime drowsiness and a warm sensation localized to the face.
Concerns About My Child's Upset Stomach
Last Friday, my four-year-old daughter woke up complaining of stomach pain and later vomited the water she had just consumed. After a short nap, she seemed to bounce back completely, engaging in her usual activities like eating, drinking, and playing around the house. Since then, aside from a bit of gas, she appeared to be doing well. However, on Tuesday night, she had a notably large and loose bowel movement. Unfortunately, last night into this morning, she was sick again, vomiting twice. Now, she is back to her regular eating and drinking habits. I'm reaching out to see if anyone has dealt with similar issues? I’m feeling quite anxious about her health. Although the doctor reassured me, my severe anxiety and OCD make it challenging to stay calm during situations like this.
Knee Discomfort on the Inner Side
A few weeks ago, I sustained a twist to my knee that resulted in discomfort lasting about 24 hours before subsiding. However, three days ago, the pain unexpectedly resumed. In the mornings, the intensity of the pain causes me to walk with a noticeable limp, while by afternoon, I can usually walk without much trouble. Although the sharp pain dissipates, there’s a lingering sense of tightness, which doesn’t feel quite right. The discomfort is primarily located on the inner part of my knee, extending slightly to the front. What should I consider as my next move? Is a trip to the doctor necessary, or could this issue potentially be managed at home? For context, I underwent hip surgery at the age of 12 due to a condition known as SCFE, and I have screws in both of my hips. Additionally, I engage in weightlifting, although I'm uncertain if that contributes to this knee issue. I’m a 17-year-old male, standing 6 feet tall and weighing 250 pounds.
