Can you take MiraLax 3 times a day?
It is not recommended to take Miralax 3 times a day for several days. The recommended dose by the manufacturer is 17 grams of powder in 4–8 ounces of water Once daily. Taking MiraLax 3 times a day may not provide additional benefit and may cause side effects.
Doubling the recommended dose (34 g instead of 17 g) once daily was used before in clinical trials. However, taking the 34 g dose for several days was associated with increased side effects (reference).
However, Your doctor may prescribe MiraLax for Bowel Preparation in higher doses (Upto 100 grams per day).
The dose of MiraLax Bowel preparation is 17 g of Miralax in 8 ounces of water EVERY 10 MINUTES until 2 liters of fluid is consumed (reference).
But you cannot use the bowel preparation dose for the relief of constipation. Such a dose may lead to serious side effects if used without medical supervision.
MiraLax is classified as an osmotic laxative. Osmotic laxatives can cause severe disturbances of your body’s micro-elements (such as sodium, potassium, and calcium).
These side effects are more likely to occur if you take an overdose of MiraLax (such as 3 times a day) for several days.
The potential drawbacks of taking MiraLax 3 times a day for several days are discussed in the section below.
Potential drawbacks of taking MiraLax 3 times a day?
Diarrhea is common after Miralax overdosing (such as taking it 3 times a day). The incidence of diarrhea with MiraLax is up to 11% with the normal dose of 17 g (reference). And of course, the incidence of diarrhea is much greater if you take MiraLax 3 times a day.
2- Bloating and Flatulence.
Bloating and gas (flatulence) are also frequent (incidence is about 7% with the usual dose).
As diarrhea, taking an overdose of MiraLax (3 times daily for several days) will lead to more bloating and gas.
3- Nausea and vomiting.
Taking MiraLax 3 or more times a day may induce frequent nausea. in severe cases, vomiting directly after you take MiraLax can happen.
4- Other Gut-related side effects
Other side effects of frequent MiraLax use include abdominal pain (cramps), continuous comfort in your belly, eructation, and dyspepsia (reference).
MiraLax is an osmotic laxative. Osmotic laxatives prevent the absorption of fluid inside your intestines. MiraLax can also draw fluid from your body into your intestine to produce the laxative effects (reference).
Dehydration can leave you with multiple symptoms such as Fatigue, dizziness, extreme thirst, less frequent urination, and confusion.

6- Electrolyte disturbances.
Frequent diarrhea induced by MiraLax overdose may cause loss of your body electrolytes.

Ask your doctor if you want to occasionally take MiraLax 3 times a day to relieve constipation (only for one day).
What to do instead to treat severe constipation?
1- Fix your False Believes about Constipation.
- Daily bowel movements are not necessary. a single bowel movement every two to three days is considered normal as long as the stool is not very hard.
- Dependency on laxatives to produce daily bowel movements can do harm more than good.
- An unnecessary increase in the dose of MiraLax into 3 or more times a day can lead to side effects and also dependency on it.
- Laxative abuse can lead to Bowel hypomotility (your colon becomes completely dependant on laxatives to produce bowel movements).
So, Increasing MiraLax 3 times a day may not the best decision. No need to increase the dose of MiraLax if you have a bowel movement every two or three days.
2- Revisit your lifestyle (diet, exercise).
- Increase the total amount of fluid you take.
- Shift from low fiber diet (such as meat) into high fiber diets such as Fruits, vegetables, and whole grains.
- Be a physically active, sedentary lifestyle is a major risk factor for severe constipation.
- Train your bowel, by trial to defecate soon after meals. This is the best time as colon motility is stimulated after food reaches your digestive tract (gastro-colic reflex).
3- Use effective home remedies for constipation.
- Drink More coffee: coffee is a powerful stimulant of your digestive system motility (reference).
- Eat or drink the juice of Prunes: it is evidenced to improve the frequency of bowel movements and softens your poop.
- Use bulk-forming fiber laxatives such as senna and Psyllium (Metamucil).
4- Check your list of medications.
You may be taking other chronic medications (such as hypertension and diabetes medications). This is common in people who are older in age.
It is not uncommon for medications to cause resistant constipation. Too many drugs can lead to such conditions such as:
- Non-steroidal anti-inflammatory drugs such as Ibuprofen (Advil) and Diclofenac.
- Tricyclic anti-depressants (used in psychological diseases and irritable bowel syndrome).
- Urinary incontinence medications (anticholinergic drugs)
- Some anti-hypertensive medications (as high dose calcium channel blockers).
- Others, the complete list is HERE.
5- Ask your doctor about alternatives.
Your doctor needs to re-evaluate your constipation and prescribe stronger alternatives if the above measures fail. Don’t abuse medications without medical supervision. Even OTC medications as MiraLax can cause adverse effects if misused.
