Question: Im currently being treated for Lyme. I have taken Doxcycline for 2 1/2 weeks, but my doctor now wants me to take only azithromycin. From what Ive researched it seems the two together could actually be pretty effective as they attack the bacteria's ability to synthesis proteins differently. My question is Would it be smart & safe to finish off the original suggested 4 week course of Doxcycline(100mg 2 D) with the now additional azithromycin(250 mg 1 d)? Or should I discontinue and switch directly to only taking the azithromycin?

Brief Answer:
Finish off the original Doxycycline for 3 weeks

Detailed Answer:

The antibiotic of choice for Lyme disease depends on the symptoms or manifestations of the disease. To be honest I have not read Azithromycin as a first line drug unless there is Penicillin allergy documented.

1) Stage 1: rash we treat with either Oral Doxycycline or amoxicillin for 3 weeks
2) Stage 2: Neurological problem (meningitis, Bells palsy) Intravenous ceftriaxone (Penicillin group)
3) Stage 3: Cardiac heart block again IV ceftriaxone
4) Arthralgia, we go with doxycycline for 3 weeks.

I agree with the school of thought that both Doxy and Azithro have different class of action but multiple antibiotics at the same time is the last bullet. If the Doxycillin does not help in 3 weeks there is no point in going ahead with it. It is better to switch to alternative therapy.

Since you completed 2 1/2 weeks, continue for another half week and stop it and switch. With that point of view you can go ahead with your doctor's treatment with Azithromycin.

Hope this helps.

I've recently discovered that when I wipe after urinating, I find blood on the tissue. I've been having some stomach problems for about a month now and had taken pinacillin for a day before finding out I was allergic to it and switched to a new antibiotic to treat an ear infection. The first time I encountered the blood was two days after the pinacillin and I don't feel pain while urinating.

I have a little boy 2yrs old and he is just over 13kgs. The doctor gave us a prescription for clonamox 125mg/5ml to have while we were away on holidays. I filled the script at the time (july) so I have the dry powder now. I need to use it today and am just wonding how much he should get & for how long? It's not written on the bottle from the pharmacy. I think it's 2.5ml or 5ml but wasn't sure. My pharmacy is not open until tomorrow morning & he really needs it tonight.
Can you help?

I was diagnosed with a Penicillin allergy in 1991. Subsequently,I developed sensitivity to peanuts. I am 66 years
old,female. I tend to have problems with nonspecific itchiness....the middle of my back, then the palms of my
hands will itch. No rhyme nor reason it seems. I was also diagnosed with allergy induced asthma when I developed the penicillin allergy. I have done well the last few years and have not needed any inhalers. I seem to have weird symptoms now that I'm older, such as the itchiness,but also experience my tongue becoming irritated for no apparent reason, or a sore throat will develop. I must say none of my symptoms are particularly serious, just annoying. Any thoughts?
