Answered by Dr. Vivek Chail 59 minutes later
Brief Answer:
Taking BIAXIN XL 500mg 2 tablets once a day is given in adult with pertusis

Detailed Answer:
Thanks for writing in.

I have read through your query in detail.
Please find my observations below.

1. BIAXIN contains clarithromycin which is an antibiotic preparation. It has been given to treat your pertusis infection.

2. BIAXIN tablet is available as
(i) BIAXIN tablet which are 250 mg or 500 mg immediate release
(ii) BIAXIN XL tablet which are 500 mg extended release

3. The recommended dose of BIAXIN for pertusis in adults is 1000 mg per day as follows

Tablet BIAXIN 500 mg (immediate release) one tablet twice a day for 14 days


Tablet BIAXIN XL 500 mg (extended release) two tablets once daily for 14 days.

4. Therefore, total dose of BIAXIN amounting to 1000 mg per day (2 x 500 mg BIAXIN taken 12 hours apart) or (2 x 500 mg BIAXIN XL taken as a single dose) is acceptable for pertusis.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.

I have the generic and there is "ER" after the word "clarithromycin" I take it the ER is the generic term for XL. So if this is the case I can/should take two tablets at the same time?

ER is extended release and the same as XL
