Azithromycin half life

Common Questions and Answers about Azithromycin half life

zithromax

Avatar_m_tn I know the cefixime has a very short <span style = 'background-color: #dae8f4'>half</span>-<span style = 'background-color: #dae8f4'>life</span> but the azithromycin stays in the body for a very long time. I am getting unpleasant side effects from it and want to know the approximate time until complete elimination from the body of a 1g dose. I did a lot of research and can't seem to find a straight answer.
Avatar_n_tn I've had it for about 5 days now (since taking the azith). I understand azithromycin stays in the system for quite some time though (3 day <span style = 'background-color: #dae8f4'>half</span> life). Any experiences ?
Avatar_n_tn Excellent. This is the second time in my <span style = 'background-color: #dae8f4'>life</span> I've taken azithromycin. The first time was many years ago and it hurt my stomach a lot back then. This time it didn't even though I took it on an empty stomach to maximize its absorption. Thanks again for your help Dr. Best regards, S.
4451049_tn?1387157037 Short course of one or 5 days is given because the <span style = 'background-color: #dae8f4'>half</span>-<span style = 'background-color: #dae8f4'>life</span> of the drug is 68 hours. That means that it takes 136 hours for this drug to completely leave your system. That's a week. It penetrates into the deep tissues and lasts for a very long time on even one dose. So a five day course lasts a week after the last dose and is cumulative during the five days. In my opinion, that's just too dangerous a drug to be on the market, considering the long list of side affects.
Avatar_f_tn Hi, I am a 22 year old male (uncurcumsized) that has had 4 sexual encounters in my <span style = 'background-color: #dae8f4'>life</span>...all but one unprotected...last year I experienced penile irritation that started with a tingly feeling that transformed in to burning after a 3 days it lasted for almost a month(3 weeks), and went away when I used anti-fungal/steroid cream for three days...I was told by a doc that it was candida from a soap irritant. No blisters or sores!
Avatar_n_tn I have read there was no change in efficacy of a single dose of azithromycin vs a 3day course or a 5day course in many other infections but havent heard the same for chlamydia Why? If azothromycin has a <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span> of three days why would this choice of treatment be an inneffective treatment for chlamydia? Thats 500mg a day for 3 days (1.5g)?
Avatar_f_tn What about orange juice? Can it affect it?
Avatar_m_tn I took 1g azithromycin 2 days after the incident (I know this is not the optimal dose, but it's all I had and should cure 93% of the time, if indeed I had it). Because of the long <span style = 'background-color: #dae8f4'>half</span>-<span style = 'background-color: #dae8f4'>life</span> (3 days) of the drug, I am not sure how long I need to wait for symptoms to appear (I have not symptoms now) before I can be sure it worked.
Avatar_n_tn Thing is ive been using cialis (20mg) for some time now, is it safe for me to take this now?. I understand azithromycin has a very long <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span>, but i cant find information on its interactions with cialis. Any advice is appreciated thanks.
Avatar_n_tn A year and a <span style = 'background-color: #dae8f4'>half</span> ago I had protected sex with a prostitute. During that my condome broke and I was IN unprotected for a minute or so. Once I realized I got out... From that point my whole life changed. I think about diseases and infections all the time, they are my main preoccupation and there isn't minute when I don't think about them. One year after the exposure I went to the doctor and I took some tests. I was tested for HIV, Gonorrhea, Syphilis, Chlamydia and Ureoplasma Urealitica.

Avatar_f_tn The maternal serum <span style = 'background-color: #dae8f4'>half</span>-<span style = 'background-color: #dae8f4'>life</span> of azithromycin is unchanged in early pregnancy and decreased at term; however, high concentrations of azithromycin are sustained in the myometrium and adipose tissue. Azithromycin is recommended for the treatment of several infections, including chlamydia and Mycobacterium avium complex (MAC) in pregnant patients.
Avatar_f_tn When will her symptoms disappear? The internet says a week, but the <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span> of azithromycin is 11 to 14 hours. That would suggest that this medicine is not present after three days. So why wait longer?
Avatar_m_tn is a single dose equivalent to multiple smaller ones, given the long <span style = 'background-color: #dae8f4'>half</span>-<span style = 'background-color: #dae8f4'>life</span> of this drug ? is it possible to get partial cure but not entirely from these ? will tests still reveal it ? if the burning goes away , is that enough evidence of full recovery ?
Avatar_n_tn Confusedmind I recently got off of doxy. The <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span> is 18-30 hours, so this means it will take 4-5 days to get totally out of my system. The pain is gone, the head aches are gone, the fatigue has subsided a little. But overall I still have somewhat of a flu like feeling througout the body. Sucks, because ofcourse it makes me doubt things. Thank you for your post... I needed that, big time.
Avatar_n_tn In vitro information helps, but there are a few things to consider which affect the results in an actual human, such as the <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span> of the drug, its distribution in tissues and fluids, reactions in the body, etc. One great thing about it is it's bactericidal, which is a great advantage. 3) As above, I wouldn't try anything else quite yet. For one thing, sparfloxacin is a similar type of antibiotic (fluoroquinolone) to moxifloxacin, and is actually quite potent as well.
Avatar_m_tn did UTI and CBC all normal. 5. A month and <span style = 'background-color: #dae8f4'>half</span> later started to date again. Thinking all this is in my head. After both of us (me and the new lady) taking all STDs test and have a negative result. 6. Had sexual intercourse and the lady got the same symptoms as I have!!!! Burning during urination burning around the anus, feeling that her vagina is bruised. 7. All her test are negative including HPV (pep). 8. Her doctor put her on 14 days of doxycycline and after that 2g of azithromycin. 9.
Avatar_m_tn This was approximately 2 and a <span style = 'background-color: #dae8f4'>half</span> weeks ago and the pain has not dissipated. It comes and goes, is present behind both testicles and lately seems to be localizing to my left testicle. The epididymis of both testicles seems to be tender and worse on the left. However there is no major swelling or severe pain. The day after I finished the cipro I went to another clinic and recieved 1g of azithromycin to cover other non gonococcal urethritis causes to my symptoms.

174515_tn?1191710869 i had a fever of 102 that won't go away. well i was probably the worst patient in history since i refused <span style = 'background-color: #dae8f4'>half</span> of what they wanted to do. no x rays no shots, no anything but a diagnosis and prescription. they have determined i have bronchitis and bronchial asthma that is pregnancy induced( hence the shortness of breath i mentioned before). the doctor after i asked 800 times if it was safe during pregnancy gave me azithromycin(z-pack) for 5 days and a ventolin inhaler.
Avatar_f_tn As a result of bronchitis yrs ago I have needed an inhaler..last one was Advair 500...only used once a day. Never needed a rescue inhaler. In December, durung a very stressfull year, I had 2 URI's then found inhaler wasn't doing the job. Referred to pulminoligist: Blood work showed the above and due to a 3rd URI he placed me on azithromax,doxycyline, Biaxin & Levequin + a shot of prednisone + a shot of one of the antibiotic's & prescriptionfor laddered prednisone.
Avatar_n_tn After a week and a <span style = 'background-color: #dae8f4'>half</span> I saw the doctor, was diagnosed with both sinusitis and bronchitis and it appeared my asthma was in control, this was a Friday. (I have had asthma my entire life and at the first signs of a sniffle and some tightness I immediately start a prednisone taper and Xopenex nebulizer). I was prescribed azithromycin and told to continue with my xopenex and prednisone. I also took cough syrup, sudafed and motrin.
Avatar_m_tn She used a condom but then took it off <span style = 'background-color: #dae8f4'>half</span> way through. I was so nervous the next day I took a prescription of Amoxicillin I had not used. I took the entire prescription over a 10 day period. I am worried sick about herpes. I have not had any sores but have had the occasional pain down both legs. I got an IGG test after 16 days that came negative for both hsv-1 and hsv-2. Am I in the clear? is there anything else I should worry about?
Avatar_n_tn No change in my answers. Azithromycin has a <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span> of 36 hours, staying in the body for days after taking it. Ceftriaxone has a half life of about 9 hours, staying in the body for about 2 days after a single injection. It is time for you to put this behind you and move on.
Avatar_n_tn (One concern I have is a uncommonly fast metabolism and a shortened <span style = 'background-color: #dae8f4'>half</span> <span style = 'background-color: #dae8f4'>life</span> of the Zithromax. I do not know if zithro is stored in fat or not ut I have none and I hit the gym and take hemp protein as a supplement. The reason I know my body does not hold on to things long is the unusually quick amount of time THC leaves my system relative to anyone I know or what the testers expected to see. (2 weeks after daily use a negative lab result with 'funky' creatine lvls.
Avatar_f_tn As would be expected in managing an infection with a gram negative organism such as Bb, amoxicillin has been shown to be more effective than oral penicillin V. Because of its short <span style = 'background-color: #dae8f4'>half</span>-<span style = 'background-color: #dae8f4'>life</span> and need for high levels, amoxicillin is usually administered along with probenecid. Since blood levels are extremely variable they should be measured.
Avatar_n_tn We know that chlamydia, Mycoplasma genitalium, trichomonas, and a few other causes, all taken together, account for roughly <span style = 'background-color: #dae8f4'>half</span> of all cases. The causes of the rest are unknown. Most NGU patients' female sex partners have nothing abnormal on examination or testing. The standard approach is to treat NGU with doxycycline or azithromycin, and if that doesn't work (about 20% of cases), to try the other drug.
Avatar_f_tn Hello, Ok so here's my story...about a month and a <span style = 'background-color: #dae8f4'>half</span> ago I was at a party and drunk out of my mind...*1st mistake* I ended up having unprotected oral (with ejaculation) and unprotected insertive vaginal sex (lasted about 2 mins, no ejaculation) with a girl of unknown status. She was also super drunk so both of our judgements were clouded. Afterwards I felt horrible (mentally) especially when I found out that she had slept with a few more guys at this party as well that same night...
Avatar_n_tn Your chances of developing long QT syndrome from taking azithromycin is VERY rare. This would be different if you told me that you had a family history of sudden cardiac death, long QT syndrome, or syncope with a longish QT on EKG. The FDA in the US is very strict. If people were dying from this medication, it would be pulled from the market.
Avatar_m_tn We did not have penetrative sex, except on one occasion when I <span style = 'background-color: #dae8f4'>half</span> entered her and was there for about two minutes before stopping (this was unprotected). the relationship consisted of her giving oral sex, which she loved doing. About two months ago, I started to experience some problems fully emptying when I was peeing. I suspected prostate, but then started to worry about whether I'd contracted an STI.
