Amoxicillin: Rare side-effects include mental changes, lightheadedness, insomnia, confusion, anxiety, sensitivity to lights and sounds, and unclear thinking. Immediate medical care is recommended with these side-effects. But if this has been happening for years and you have been taking it regularly for some reason it is unclear what is going on. If this is occasional, would stop taking it right now. ...Read more

Is dizziness and faint feeling normal for taking amoxicillin ?

Amoxacilin: That is not a normal reaction to amoxicillin. The fact that you do not have any skin rash or shortness of breath makes it unlikely that it is a drug reaction. However I would stop the amoxicillin and if the symptoms persist go to the ER. ...Read more

I have been feeling ery weird and dizzy lately. I just got over a sinus infection. I am taking amoxicillin 2g a day. Is this a side effect of the meds?

I have been feeling ery weird and dizzy lately. I just got over a sinus infection. I am taking amoxicillin 2g a day. Is this a side effect of the meds?

Probably not the med: Though meds can cause dizziness..In this case, in light of the sinus infection...I usually see it coming from the fact that the sinus drainage, causes some inflammation and swelling around the opening for the eustachian tubes, and this causes the middle ear to not drain adequately, and the build up of fluid and pressure...Often leads to the dizziness. ...Read more

My right ear not ok..clogged and have pain and always dizzy .usually no wax in my right ear..kind of dry ..I tried taking amoxicillin but still bad

Otoscope!: The easiest way to figure this one out is have someone look in your ear with an otoscope. It's most likely wax build up or fluid trapped behind your eardrum. If you're in pain, it' could be an infection. Hope this helps! ...Read more

I've been dizzy for 3 days now what could it be I've been on amoxil (amoxicillin) and dexamethasone for 6 days now for sinus and throat infection?

I've been dizzy for 3 days now what could it be I've been on amoxil (amoxicillin) and dexamethasone for 6 days now for sinus and throat infection?

Anything: Your dizziness can have any cause at this time. Change in blood pressure especially when you change positions, known as orthostatic hypotension. Side effects of medication is possible too, especially dexametasone. I'd stop (it sounds an overkill to treat sinus/throat infection for that long with it). Also, make sure you drink plenty of fluids and take over-the-counter probiotic with your ab. ...Read more
