Doxycycline Hyclate and lethargy

Well, ive been off the doxy for about 5 days now, and im still experiencing the side effects, noticeably, the depression...and weakness....and still don't have a strong appetite. From what im reading, it will take several weeks for these symptoms to go away....I told my doctor about the side effects, and he did not at all seem concerned or surprised, except to say that he would not put me on doxy anymore....i will never take this drug again....thank heavens for this site, because I at least I know what all this is caused by. Just a quick recap of all the side effects I have suffered....Ringing in the ears, loss of appetite, major gas, weight loss, depression, headaches, lethargy, loose stool, chest pains, back pains, and burning eyes.

I had a cyst that became infected, and was prescribed Doxycycline - I've been taking it for about four days now and have been experiencing a lot of dizziness and lethargy. I got online to research, because dizziness is not listed as a potential side effect on the prescription info sheet I have at home, and I'm glad I found that others have experienced the same symptoms I have. I'm on a ten-day course for this med, so I guess I'll finish it, but I'm so woozy from the dizziness!

I have been taking doxycycline hyclate for acne for the past three weeks and find that I am now urinating a lot especially after intake of liquids and it seems as if I empty the same amount that I consume.This is really very annoying and inconvenient.

I took doxy (100 mg a day) for approximately 12 months as a malaria prophylaxis. I experienced mild heartburn for the first month, vomited a couple of times until I learned I must eat a full meal first, and was very sensitive to the sun. After reading the other posts I now think I also experienced two other side effects: extreme lethargy and dizziness--at the time I thought it was due to African heat.

I recently had gum surgery and was prescribed dox. I am only taking 100 mg/day, but I've had extreme lethargy, headaches, itching, swollen lips, nausea and bouts of confusion and dizziness. I feel very sad on this medication and I'm usually a very happy person. I'm stopping the meds today, so hopefully I will be back to my normal self within the next week. I wish I had researched the drug sooner so that I could have stopped taking it earlier...I thought my reactions were due to the pain meds, but I was mistaken!!!

I have been on this antibiotic for pneumonia for a week. I already have a possible ulcer and have a prescription for zantac. I am on 100mg BID for two weeks. Since taking this medication my ulcer has become much much worse with frequent heartburn and a lot of drowsiness/lethargy. I feel like I float through my day and am confused and using the wrong words a lot, and just not paying full attention to anything. I have a constant pain right under my sternum that flares up and a lot of mid to lower back pain, esp. at night. I have had a headache for the last four days. I did some research and found that ANTACIDS SHOULD NOT BE TAKEN WITHIN TWO HOURS OF DOXYCYCLINE!!! Bummer for me, since I have been drinking Mylanta like it was my only source of hydration.

On day 5 - 100mg 2x day for moderate adult acne.

Really noticed a decrease in appetite mainly, mild nausea with the AM dose, irritability (maybe more the "out there" feeling), definite .. lethargy/drowsiness. I've been going to bed at 9pm. Heh. Thank goodness I don't have the heartburn a majority of you are talking about :o( Sorry.

In Guyana ,South America ...we just had a flood about 50 deaths from Leptospirosis ...medical teams handed out Doxy like candy...to 75% of the Guyanese population (Guyana where Jim Jones killed people with KOOL AID ) about 450000 people drank Doxy ( 2 X 100 mg ) in one dose per week ...the population is in the second week of Doxy ..the side effects were bad ...for me personnally ..bad headaches,lethargy ...all of the above symptoms described by u guys were reported by individuals ......anyhow
hoping i never have to drink that shitck again

Constipation, abdominal bloating and fullness (despite regular doses of probiotics), lethargy
