MiraLAX Onset Time: When Will You Feel Relief?

Understanding How MiraLAX Works

MiraLAX is a brand name drug that contains polyethylene glycol 3350 or PEG 3350 as the active ingredient. It is an over-the-counter osmotic laxative and is used for treating short-term constipation or cleaning out the colon before colonoscopy . 

By pulling liquid into the stool, MiraLAX helps to soften stool, increase stool volume, thus, make it easier to pass. It comes in the form of a sugar-free, gluten-free powder to be mixed in a hot or cold liquid and taken by mouth. 

Common Reasons for Using MiraLAX

• To treat occasional constipation

• For bowel prep before a colonoscopy

Keep in mind that MiraLAX should not be used to treat chronic constipation without a doctor’s approval. Let your healthcare provider know if your constipation lasts more than 7 days. 

What is the recommended MiraLAX dose?

The recommended MiraLAX dose is 17 grams once a day for adults and children 17 years of age and older. Check with a healthcare provider before giving MiraLAX to younger children.

You can use the indicator line on the bottle top to measure 17 grams of MiraLAX powder. Single-dose packets are also available. Dissolve by stirring the powder in 4 to 8 fluid ounces of any liquid (hot, cold, or room temperature), such as orange juice, tea, coffee, or other liquids. Drink the liquid form immediately. Do not combine with starch-based thickeners.

MiraLAX powder for bowel prep contains 238 grams of polyethylene glycol 3350 to be mixed in 64 ounces of clear liquid such as water, Crystal Light, or Gatorade. This mixture can be refrigerated since many people find it tastes better chilled. This oral solution is used to clean out the bowels before surgical procedures on the gastrointestinal (GI) tract, such as a colonoscopy.

How MiraLAX Works to Relieve Constipation

MiraLAX is an osmotic laxative that works by attracting water into the colon (large intestine), making the stool softer, and increasing the stool volume, making it easier to pass. 

By drawing water into the colon, MiraLAX provides gentle relief from occasional constipation. Although uncommon, it may cause side effects such as nausea, cramping, discomfort, bloating, or urgency.

In contrast, other drugs, such as stimulant laxatives (Senokot or Dulcolax tablets), work by stimulating muscles in the colon to contract. They are more likely to cause stomach pain, cramping, and sudden urgency compared to MiraLAX and other osmotic laxatives.

Timing and Effectiveness of MiraLAX

Expected Timeline for MiraLAX to Work

When taken to relieve occasional constipation, MiraLAX will usually produce a bowel movement in 1-3 days.

If you are taking MiraLAX for colonoscopy bowel prep, bowel movements usually begin within a few hours of drinking the first dose, although it can take longer for some people. 

Factors That Affect How Long MiraLAX Takes to Work

• MiraLAX may take longer to work if you have severe constipation.

• Drinking plenty of water can help MiraLAX to be more effective.

• It may be less effective or take longer to work if you have constipation due to a reason other than dry, hard stools; for example, constipation caused by medications or intestinal conditions.

• If you do not poop after 3 days or need to take MiraLAX for more than a week, call your doctor. You may have a more serious condition, such as bowel obstruction.

What to Expect When Taking MiraLAX

You should have a bowel movement 1 to 3 days after you take MiraLAX. It is unlikely you will experience sudden urgency after you take this laxative. If you do not experience relief from constipation after taking the recommended dose of MiraLAX for one week, consult your healthcare provider.

Understanding the Full Effect

• MiraLAX provides an effective combination of hydration, stool softening, and gentle peristalsis (muscle contraction in the colon) to ease bowel movements.

• It provides relief from constipation without harsh side effects that can sometimes occur with a fiber supplement, mineral oil laxative, or stimulant laxative. 

• Side effects such as bloating, cramping, gas, and urgency are less common with MiraLAX than with other drugs used to treat constipation. MiraLAX is generally well-tolerated.

• Serious side effects, such as allergic reactions, are rare.

Duration of MiraLAX Effects and Potential Side Effects

Managing Expectations: How Long Does MiraLAX Relief Last? 

Miralax is used for short-term treatment of constipation. The effects last for about a day and may take up to 2-3 days to be fully removed from your system. The laxative travels through your digestive system and is eliminated from your body with stool. Therefore, you need to take MiraLAX every day for it to continue working. 

However, you should not use MiraLAX for long-term relief from chronic constipation without a doctor’s approval. Tell your doctor if your constipation lasts more than 7 days or worsens after taking MiraLAX. You may have a more serious condition that needs to be diagnosed and treated. 

Keep in mind that overuse of laxatives can lead to dependence. Chronic polyethylene glycol laxative use can also cause side effects such as diarrhea, dehydration, and electrolyte imbalance. While MiraLAX is perfectly fine for occasional constipation, lifestyle changes such as eating a fiber-rich diet and regular exercise can reduce the risk of constipation. 

Managing Dosages for Sustained Relief

Do not take MiraLAX more than once a day. Taking more than one dose a day may not have the desired effect and can increase your risk of severe side effects.

Common Side Effects of MiraLAX

Side effects of MiraLAX include nausea, cramping, bloating, and gas. You may also have watery or more frequent stools. Tell your doctor if these adverse effects are severe or do not go away in a few days.

When to Seek Medical Advice

Call your doctor immediately or seek emergency medical care if you develop an allergic reaction (hives) or severe diarrhea. Also, tell your doctor if you have signs of rectal bleeding. Do not use MiraLAX to treat constipation for more than seven days without consulting your healthcare provider.

• Before taking PEG 3350 (MiraLAX), tell your doctor if you have a history of congestive heart failure, kidney disease, or liver disease. 

• Check with your healthcare provider before taking MiraLAX if you are on other medications. Drug interactions can make medications less effective and increase the risk of serious side effects.
