For Rickettsial Infection "I've never written a drug review before. My experience with doxy was horrendous! The first day, 2 x 100 mg, I didn't have any symptoms. The 2nd day brought on an intense panic attack and irrational thoughts. My mood was so labile, one minute laughing, followed by crying intensely. I'm a sensible person, and this just floored me. It's reported that psychiatric effects occur in 1%-10% of people taking doxy. There are cases where people with no psychiatric history and normally content have had suicidal ideation and completed suicide. My doctor and pharmacist were unaware of this, despite 'depression and anxiety' listed on the consumer information leaflet."

For Bronchitis "I took this while taking a very strong steroid, and the steroid gave me terrible anxiety during and after. I thought it was all over and had a few days left of the doxycycline, and honestly, I don’t know how anyone can stand taking that medication. It gave me a ton of anxiety during and after that I had at first attributed to the steroid. It also gave me a headache while it worked its way out of my system. I will, however, say that I got better, and I was the sickest I had ever been with acute sinusitis, acute bronchitis, and suspected Covid but with a negative test."

For Acne "I currently have moderately severe acne, which has resulted in anxiety, depression, and generally feeling hopeless, and I cannot tell you how hopeful I am that this may be the answer. I have only been taking this medication for 6 days (50 mg a day) alongside the birth control pill Diannette (Brenda), and my skin already appears to be clearing. I am amazed because I have tried absolutely everything, including Accutane, which gave me some horrendous side effects. Initially, I had a small breakout, but these pimples already seem to be healing. The only side effect I have experienced is feeling like throwing up. I will post a further update when I have finished the course. But I am hopeful!"

Doxycycline for Lyme Disease, Neurologic "My daughter (16) was prescribed Doryx 150 mg 2 x a day for Lyme disease after exhausting all other antibiotics and her symptoms returned. After two doses, she started to experience paranoia and anxiety. Could this be a Herxheimer's reaction, meaning it is working (resurgence of original symptoms of Lyme disease), or is this a severe adverse reaction?"

For Prostatitis "Was first prescribed this at 100 mg twice a day. At first, it was doing okay, but then I noticed I was in fear all the time, Googling everything and assuming it was going to be the end of me. This stuff made me have severe anxiety and depression. It brought the prostatitis to a minimum and kept it at that level, so I am thankful for that. That being said, the dark side of me really came out. Please read for yourself about this medication before taking. P.S. still suffering from side effects."

For Bacterial Infection "I just feel ethically obligated to comment here, as I have health anxiety and saw many scary experiences that people have had with doxycycline. If you are prescribed it and are worried about side effects (from reading reviews here, for example), fear not, as it is generally very safe, and if you are like 99% of people, you will not have any issues. I was initially prescribed Cephalexin for an infected scrape, and within 2 doses gave me insane anxiety/mood swings/etc. I have never reacted that poorly to an antibiotic, and didn't even know they could do that kind of thing. The doctor then switched my prescription to doxy, and I was super nervous to take the first dose. After taking it 100 mg 2 times a day for 5 days, I really felt nothing besides very minor drowsiness and very mild heartburn. The two things to heed are: you must wear sunscreen on this antibiotic, you must eat something with each dose (and chug a cup of water with the pill), and don't lie down for at least 30-60 minutes after taking a pill."

For Chlamydia Infection "I found out I had chlamydia 3 days ago. With the doxycycline, I've had a really upset tummy but not been sick. My main problem is I'm really aching and do feel like my anxiety level has increased. I take two 100 mg tablets a day. Thank goodness I only have to take it for 4 more days, as I'm taking other medication on top of this. I'm not a big tablet taker at all, and I've lost my appetite."

For Acne "WORST medication I have ever taken, wow. I was having a few acne breakouts due to the IUD. Got the IUD removed and was put on doxy. Wow, within 2 days I was breaking out nonstop but powered through because of a purge. Fast forward to 2 months later, skin is so bad it looks like I had hives on my face, but it was just actual huge pimples everywhere. I would cry and never leave the house. Thankful my derm put me on spironolactone and it saved me!! 2 months into no doxy and just spiro and things are looking AMAZING. Moral of the story is ... do NOT TAKE THIS. I don't know one person that it has worked for, but everyone is different! Best of luck."

For Pneumonia "Seemed to work at first, but then about two weeks later (still taking it), I’m starting to feel the bubbling in my lungs again. On top of that, I got weird blisters I never seen before in my entire life on my hand, my throat was so sore I could hardly swallow. It stopped once I stopped taking the medication, I took all except one. It does cause nausea, which I remedied by eating a lot of food and drinking water back to back, but after an hour of taking it, I would feel hot and dizzy and anxious and have a weird shortness of breath, like I forgot how to breathe. I’m just going to put this medication down as an allergy. Never taking it again, may need to be on another antibiotic because I don’t think my pneumonia has cleared."

Doxycycline for Acne "I’ve been taking a 75 mg dosage for about 6-8 months. It cleared my face, but I’ve noticed several side effects that developed over time, including weight loss, strange thoughts, mild anxiety, and mild depression."

For Bronchitis "First time I took doxycycline, had horrible, severe anxiety, felt as if I was clawing up walls, stopped taking 3rd day. Recently was given doxycycline again for lung infection, I refused medication, shared with doctor, I'll take any alternative, I'm not taking doxycycline. Dr. states I had a very severe lung infection, I had no choice. After a long discussion, I gave the med a chance, I'm taking 100 mg, 2x daily for 5 days. To my surprise, on 4th day, I've had no side effects. Lung infection clearing up, I can breathe fully now, thank goodness. I am able to sleep, just feel a little tired, but manageable. I believe various med manufacturers make a difference in side effects. I had the same experience with Amox/Clav. Ask pharmacy, what pharmaceutical company, try different pharma company. Good luck to everyone."

For Upper Respiratory Tract Infection "Each time I take doxycycline, my side effects can vary greatly. I used to tolerate it okay, but now I experience a range of side effects from dizziness and nausea, but eating alongside the medication helps prevent this usually. Joint pain and headaches tend to peak around day 3-4, and I feel a bit anxious and depressed or moody sometimes, and sadly nothing helps this. It's been rare that I've been able to complete a full course, but thankfully my infection usually clears, and if it doesn't, I'll take another medication. I do tend to have more energy with the medication, and in addition, it tends to help infections quickly. My options are limited due to allergies. I had a major sinus infection this time and fluid in the ears. I experienced severe headaches, nausea, fatigue, and congestion from mucus flooding down my throat. It was absolutely horrible, and I was in so much pain. Doxycycline has taken away most symptoms overnight. Side effects seem worth it right now."

For Upper Respiratory Tract Infection "I’ve been taking doxycycline for 5 days, 100 mg once a day. I have anxiety, for which I take antidepressants. This drug really aggravates my anxiety and my IBS. Also, I have a lot of back pain. I only have one kidney that works, and I feel it’s aggravated that too, so I’m now stopping it as I can do without the side effects and the added anxiety. This is the second time I’ve taken it, and it was like that last time, so no, I won’t be taking it again. I live in the UK and retired, so I have free medicine."

For Lyme Disease "Took 200 mg daily for 30 days after testing positive for Lyme. Cleared up symptoms within a few days but made me very tired and had trouble sleeping at night. To be honest, I felt worse on the antibiotic than when I did with Lyme as it made me very anxious and restless at nighttime. Some people, why are taking this for more than a month, lol? I just read a lady on here taking it for 5 years... felt worse as soon as she stopped (deep sigh) this is called a placebo response, look it up and save your gut biome. Lyme can't live outside your white blood cells as it's a spirochete, meaning cyst Lyme doesn't exist. Please don't believe this chronic Lyme crap. Go and read some evidence-based journals for God's sake."
