Metformin Side Effects
People with diabetes probably know about Metformin and its side effects. This article is for all those who wish to learn more about this drug. Metformin is a medication used in diabetes (especially type 2 diabetes) treatment, (including patients who are overweight). It is used in treating polycystic ovaries syndrome as well.
According to some sources, it is one of the world’s most prescribed anti-diabetic medications. Although it is considered quite safe, it can cause some side effects. Metformin side effects are not very severe, but some people are too sensitive and can have bad reaction to this medication.
Possible Metformin Side Effects
Metformin does not cause many side effects, in condition it is used in appropriate cases and in recommended doses. This medication helps reducing triglycerides and can contribute to preventing cardiovascular problems in people who suffer from diabetes.
Contraindications are possible in patients who suffer from any problem related to lactic acidosis. There can be kidney problems and liver or lung problems. Patients with hypothyroidism should be extra careful with this drug and must consult their doctor first.
Metformin side effects that can sometimes occur are: headache, abdominal cramps, nausea, diarrhea, vomiting, flatulence and other gastrointestinal problems. Some users may experience weight gain. Allergies to this drug are also possible, so if you experience any sort of allergic reaction (rash, difficult breathing, pain in your chest, mouth swelling, lip swelling, face or tongue swelling) call your doctor immediately. These are signs of allergic reactions, so if you experience any of these, you will have to get immediate medical help.
Even if you have never had any kind of allergy, you never know what can happen. Skin rash is usually a mild side effect and it will subside once you stop taking metformin. Breathing problems and pain in chests are serious side effects, so you should not ignore them. Finally, lip swelling, face swelling, throat swelling and tongue swelling are very serious side effects, and you must contact your doctor right away.
Also, if you experience any kind of unexplained pain in bones or notice that your urine is darker than usual, call your doctor. If you feel any pain while urinating, feel dizzy and weak or feel cold, this could indicate low tolerance to metformin. One can also have changes in his stool, pain in muscles, appetite loss, severe vomiting, short breath and hands/ankles swelling. Fever and sore throat were also reported by some users. However, sore throat and fever are not severe side effects of this medication and they are not difficult to treat. Severe vomiting can lead to dehydration, and if your appetite is poor, you may start feeling quite weak.
Although this medication is commonly used and considered very safe for patients, you never know what can happen to you, so don’t do anything without asking your doctor first. Before starting with this drug, your doctor must know about your medical past. It is very important to follow your doctor’s instructions. Do not change the dose on your own. Even if you think that your dose needs to be modified, you must never change it without your doctor’s knowledge.

how is the gas problem with metformn 500 mg
May 14th, 2011
It never gets any better!

I developed severe gastritis, diarrhea, noticing entire tabs in my stool and have fought with uncontrolled bs since starting on metformin. First 500 bid, then added glipizide 10 bid, then added another 500 metformin bid so now taking 1000 mg bid. Still bs in the 170 – 200 range. My family kept saying that it had to be what I was eating. I would go home and cry about it and think they were right. My hypothyroidism is also now out of control so that med has also doubled.
I am so discouraged, not having ins and unable to go to endocrinologist on ss benefits makes it even harder.
Thanks

Audrey,
So sorry about your current situation, glad I have insurance , but it does not cover supplies. The diabetic education class was very helpful that one was covered by insurance. Don’t know if you have medicare, i think its covered.My bmi is 27 had been watching my carb intake even before I was diagnosed. I’ve lost 11 lbs over 1 month time and this time cut my carb intake to about 150 to 180 grams a day. Your right about the gas , what gets me most is the loose stool. I’ve resorted to taking charcoal capsules to help with the gas. Plus a back up underpants just in case.

Only your doctor can tell you how much Metformin and how many times a day you need to take. Do not take more or less of it than what your doctor has prescribed. Metformin controls diabetes but does not cure it. Continue to take metformin even if you feel well. Do not stop taking metformin without talking to your doctor.
Not everyone who takes metformin is a Type 2 diabetic. Metformin may be prescribed for other uses; ask your doctor for more information regarding this.

I have been taking Metformin for 6 weeks, 500 mg per day, when does the diaherra stop, is this he weight loss program they talk about with this med. I can only take it with my evening meal because I need a pot within 2 hours and then it lasts for another 3-4 hours everyday. Any ideas on how to stop the diaherra, help please.

i’ve been on two times 500mg daily since December 2010, i have recently got a leg rash and within the last few days suffered from indigestion at night after meals, thats the first time for any side effects for me, as for yourself, the constant toilet requirement would indicate you need alternative medication to metformin, a visit to the doctor is urgently required i think,

I have been on Metformin for 2 weeks and am finally up to 2 500mg in morning and again at night. I am also on Depo Povera and have been for 6 years. Just started spotting and bleeding, haven’t had a period in 5 years. Feeling nauseaus all day long. Worse in the AM and Dinner time. Slight bumpy rash on chest. Am I normal?

For the first 6 weeks after starting Metformin I felt nauseous and like I had the flu. After about 5 weeks I totally lost the use of my taste buds. I DO have one taste in my mouth. It’s like wadded up cardboard wrapped in a waxy, mettalic skin. EVERYTHING tastes that way, be it water or chocolate. I’m now repulsed by food. I usually spit out half of what I put into my mouth and I’ve lost 7 of my 172 pounds in the last 10 days. I saw a doctor 6 days ago (at the end of week 6) and I immediately stopped taking Metformin at his order. I certainly hope my sense of taste comes back because I DO like the taste of food and drink. The flu-like symptoms have subsided.

Ask your MD for the XR formula. It has decreased my bouts of diarrhea from daily to every third or fourth day. This is sooo much better.
