Anxiety, breathing difficulty, tremors, post-flu compilation. 14 apo-clarithromycin prescribed. Should i be concerned?


As a result of a post-flu complication, my doctor had prescribed me a bottle of 14 apo-clarithromycin pills. I was instructed to take one pill during the morning and another during the night -- on a full stomach. I took one last night, and another one this morning.

Approximately 3 hours after the second pill, I suddenly began experiencing anxiety almost in the form of what many people call a panic attack. I had difficulties breathing, my whole body was shaking, and I was confused.

I had zero experiences of such prior to this sudden anxiety episode. I have read studies that shows that some rare side-effects of clarithromycin include anxiety, hallucinations, insomnia, depression, and nightmares. An article from "The Psychiatrist" even discussed an extreme case where a 19-year old female developed an "immediate psychotic reaction" after having received only two doses of clarithromycin. I am only 17 years old.

Should I be worried? Should there be any further adverse side-effects of the drug, what am I to do? Thank you.

I understand your concern.
The side effects you mention is very rare nd uncommon.
May be you had it.
Now don't take the next dose of that medication, because it may trigger the same pnic symptoms again.
Consult your physician and tell him about the episode.
There are several post flu medication available for him to prescribe.
Wish you speedy recovery.

Thanks for choosing health care magic for posting your query.
The side-effect that you are describing is not a very common side-effect. But it is very much possible that you might have had a reaction to clarithromycin. if you are fine right now, you need not worry about what you had experienced. But then you should not take the next dose of medication as there is high chance that similar thing can recur.
meet your physician and discuss this episode with him. post flu problems can be taken care of many different medications and hence you can avoid this particular medication.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.

Wish you good health,

Hi friend,
Welcome to Health Care Magic

It is theoretically possible, but extremely rare.
Give the benefit of doubt / stop the drug /
See your doctor / Have a different antibiotic...
The problem will pass off by itself...

[Stopping for a time / and challenging by re-introducing - can confirm the role / but it is unnecessary and can be dangerous]

Take care
Wishing speedy recovery
God bless
Good luck
