Miralax (generic name: Polyethylene glycol 3350) is a laxative drug used in the treatment of patients suffering from constipation or irregular bowel movements. Polyethylene glycol 3350 is in a class of medications called osmotic laxatives. It works by causing water to be retained with the stool. This increases the number of bowel movements and softens the stool so it is easier to pass. Polyethylene glycol 3350 may be habit-forming. For this reason you should not take a larger dose, take it more often, or take it for a longer period of time than your doctor tells you to. Constipation is a very common condition that affects people of all ages. It can mean that you are not passing stools (faeces) as often as you normally do, you have to strain more than usual or you are unable to completely empty your bowels.
Miralax Side Effects:
As with any drug, there may be side effects from taking Miralax, including bloating, gas, upset stomach, dizziness and increased sweating. More serious side effects may include severe or bloody diarrhea, bleeding in the rectum (anus), blood in the stools or severe or worsening stomach pain, cramping or bloating. If you experience any side effects you must seek medical attention immediately for safety.
You should follow the instructions of the doctor who prescribed Miralax to you. Directions and dosage information can also be found on the pack or leaflet inside the pack. Miralax comes in powder form, and should be mixed with liquid as per the instruction on the packet and from your doctor. You should store Miralax at room temperature away from direct sunlight and heat. Do not use more than directed as taking too much Miralax can cause your body to become accustomed to using the drug.
If you are allergic to any of the ingredients of Miralax, you should avoid taking it and inform your doctor. You must consult your doctor if you have any pre-existing medical conditions including any nausea or vomiting, ulcerative colitis, irritable bowel syndrome (IBS), liver or kidney disease, or if you have had any sudden change in bowel habits. You must consult your doctor if you are taking any other medications as they may interact with Miralax, including any medications for bowel or digestive disorders or any over the counter medications or vitamins. It is important that you inform your doctor if you are pregnant, planning to conceive or breastfeeding as Miralax may cause harm to unborn and new born babies.
