Flagyl from $0.51 per pill

Stop Flagyl (Metronidazole) and consult a doctor or go to a hospital right away if:

  • You have swelling of your hands, feet, ankles, face, lips or throat which can cause difficulty swallowing or breathing. You may also notice a rash with itching (hives) or rash of nettle (urticaria). This may mean that you are having an allergic reaction to Flagyl.
  • A serious but very rare side effect is a brain disease (encephalopathy).
  • Symptoms vary, but you may have a fever, stiff neck, headache, seeing or hearing things that are not there. You may also have trouble using your arms and legs, trouble speaking or feeling confused.
  • You develop blistering rashes, scaling or bleeding of the skin around the lips, eyes, mouth, nose and genitals. You may also have flu symptoms and a high temperature. These could be signs of something called “Stevens-Johnson syndrome or toxic epidermal necrolysis”.

Talk to your doctor right away if you notice any of these side effects:

  • Yellowing of the skin and eyes. This could be due to a liver problem (jaundice).
  • Unexpected infections, mouth ulcers, bruising, bleeding gums or severe tiredness. This could be caused by a blood problem.
  • Severe stomach pain that can reach the back (pancreatitis)

Side effects are often the body’s reaction to certain foods and medications we take. While most people will not have any adverse reaction to a common antibiotic like Flagyl (Metronidazole), it does not always conclude that certain individuals will not experience some of these Flagyl side effects.

It is important to understand that Flagyl side effects are rare, but somehow occur to certain individuals. If you are included with isolated cases of people who have certain side effects of Flagyl (Metronidazole), it is always recommended that you consult your doctor about it, especially if it was your doctor who has prescribed it with this medicine. Side effects such as allergic reactions are always considered as a serious adverse reaction to a particular drug, but the side effects of Flagyl are unlikely. Keep in mind that any adverse reaction that someone has with Flagyl will not always mean the same thing will happen to you, and vice versa.

If you have a bacterial infection and your doctor has prescribed you with a course of Flagyl (Metronidazole) treatment, keep in mind that no matter how potent and effective this antibiotic is against bacteria, the effectiveness of the antibiotic does not mean much if you do not follow the instructions Of course treatment given to you by your doctor. Whenever it is a point to end your antibiotic treatment course, even if you already feel well or healed in the middle of your treatment. There is a clear possibility that there are still traces of the bacteria that caused the infection and stopping half way means that you are giving them a chance to recover.


The doctor prescribe me Flagyl after diagnostics of a giardiasis. After 5 days of treatment I took some tests. Unfortunately, the cysts were still here, so the doctor increased the dosage for another 3 days, after which the tests were already clean. I can say that Flagyl is an effective medicine, only all these days I felt slight dizziness and nausea, calming myself only the ability to recover in a short time.


Not so long ago, a medical examination took place. It turned out that I have bacterial vaginosis. Although there were no obvious symptoms of the disease.
The doctor advised taking the preparation Flagil not only for me, but also for my boyfriend. For him Flagil was discharged in tablets, and for me in the form of gel. In general, an excellent drug, both helped! We are glad! I did not have any side effects, only the boyfriend was scratching his eyes for a while, but then it quickly passed.
