I've experienced it, but not due to Metformin.

if I

also take

motrin for pain.

immediately.

Hi waitingmore. People will jump in soon with any
experiences they may have had with metformin but in the mean
time...

I have never taken metformin but I do know it is a med that
should be started at lower doses and ramped up over time. I
am not sure by your post whether the first time you took
metformin was 2 days ago or whether two days ago was the
time you took the higher doses.

Second, regardless of a new med or not I wouldn't have let
those severe symptoms go unchecked. They could be totally
unrelated to the med and quite possibly a heart attack.
Let's hope the pressure was from gastric disturbance. But
lactic acidosis is a big concern also:

This is a condition that can be a side effect of metformin
and often rears it's head after a dose ramp-up and more
likely to occur in someone with underlying kidney or liver
problems. Kidney problems are a possibility with diabetics,
especially if they have been running high numbers for a
while. Symptoms are: nausea, vomiting, abdominal pain, lack
of appetite, feeling really "off", weakness and difficulty
breathing. It is a serious side effect and it is recommended
going off the drug immediately and reporting to your doctor.
So, sounds like a talk with the doc pretty soon is in order.
Good luck, let us know.

Symptoms of chest pressure and difficulty breating warrant an emergency
room visit. Get in to see your doctor pronto. This could be a simple
gastric disturbance which new users of Metformin experience. And I agree
with Ozgirl that this dose is too big for a starter dose. I was started
with one 500 mg dose a day. But we're not doctors!!!! Go see yours. Your
ticker is too important.

Metformin can cause a chest pain that can be very scary.  My doc told me
that. However, you are taking MUCH too much.  You need to start at a
lower dose and work up.

My doctor had me try the max dose last month and I ended up with the
same kind of symptom you experienced despite years of taking 1500 mg a
day with no problem at all.  I almost ended up in the emergency room as
I couldn't breath and was having sharp left sided pains.

But because you are new to this, you should contact your doc and see
what he says. The symptoms of heart attack and Met overdose are too
similar for comfort.

Would suggest you notify your doctor(s) ASAP.  Would be concerned about
drug-induced lactic acidosis.

You are welcome.

All praises belong to God, Whom I love with all my heart, soul, mind,
and strength :-)

In Christ's love and service forevermore,

Andrew

Waiting I have never experienced a reaction as you describe.  Perhaps is
completely unrelated or maybe it is related.  I think you should talk to
your doctor.
