Milk Of Magnesia: Quick Constipation Relief

Milk of magnesia, or magnesium hydroxide, is an over-the-counter medication that can provide quick relief from constipation. It is an osmotic laxative that works by drawing water from the body into the bowels, softening the stool and making it easier to pass. It can start working within 30 minutes to 6 hours, making it a popular choice for those seeking fast relief from constipation. However, it is important to note that milk of magnesia is only recommended for short-term use and should not be taken for more than a week without consulting a doctor.

Dosage recommendations

Milk of magnesia is available in liquid, pill, or chewable tablet form. The dosage varies depending on the formulation, brand, and the user's age. It is important to follow the instructions on the package or as directed by a doctor. Here are the general dosage recommendations for milk of magnesia:

• Adults and adolescents 12 years and older: 2–4 tablespoons (tbsp), or 30–60 milliliters (ml).
• Children ages 6–11 years: 1–2 tbsp, or 15–30 ml.
• Children under 6 years of age: Parents, caregivers, and guardians should consult a doctor before giving milk of magnesia to children under 6.

It is important to note that the maximum recommended dosage in a 24-hour period is 60 ml. Milk of magnesia should be taken once a day, preferably at bedtime, and followed by a full glass of water (8 ounces or 240 milliliters). It is also recommended to shake the bottle well before each dose for liquid formulations.

Additionally, it is advised to wait at least 2 hours before or after taking other medications to avoid potential interactions. Milk of magnesia should only be used for short-term relief of occasional constipation and should not be taken for more than a week without consulting a doctor.

Side effects

Milk of magnesia is a popular over-the-counter medication for constipation relief. It is generally safe and effective, but there are some side effects to be aware of.

The most common side effect of milk of magnesia is diarrhoea, which can lead to dehydration if it becomes severe or prolonged. It is important to drink plenty of fluids while using this medication to prevent dehydration. If diarrhoea occurs, stop taking milk of magnesia and seek medical advice if it persists or gets worse.

Other possible side effects include nausea and vomiting. These are more likely to occur if a person takes more milk of magnesia than recommended or for an extended period.

In rare cases, an allergic reaction may occur, characterised by symptoms such as difficulty breathing, swelling of the face, lips, tongue, or throat, severe dizziness, or rash. Seek immediate medical attention if you experience any of these symptoms.

Additionally, milk of magnesia can cause serious side effects such as no bowel movement after taking it, rectal bleeding, and slow or irregular heartbeat. If you experience any of these side effects, discontinue use and seek medical attention.

It is important to note that milk of magnesia may interact with other medications, including prescription drugs, supplements, and vitamins. Consult your doctor or pharmacist before using milk of magnesia if you are taking any other medications.

Who should avoid it

Milk of magnesia is not suitable for everyone. It is not recommended for people who:

• Are under the age of 2
• Are dehydrated
• Have specific medical conditions, such as gastrointestinal disorders or electrolyte imbalances
• Are allergic to any of the ingredients
• Are on a magnesium-restricted diet

There is insufficient evidence about the use of milk of magnesia during pregnancy or when nursing. Pregnant people should only use it under the supervision of a doctor. It is also recommended that people taking other medications consult a doctor before using milk of magnesia, as it can interfere with the absorption of other drugs.

People experiencing symptoms such as nausea, diarrhoea, or stomach pain, or those who have had sudden bowel changes lasting longer than 14 days, should also avoid taking milk of magnesia.

Other treatments for constipation

Milk of magnesia is a popular over-the-counter medication for treating constipation. It works by drawing water from the body into the bowels, softening the stool, and making it easier to pass. It can start working within 30 minutes to 6 hours, providing quick relief from constipation. However, it is important to note that milk of magnesia is intended for short-term use and is not suitable for everyone.

Fiber Supplements

Fiber supplements such as psyllium husk or methylcellulose can help increase stool bulk and promote regular bowel movements. It is important to drink plenty of water when taking fiber supplements to ensure their effectiveness. Eating high-fiber foods such as whole grains, beans, vegetables, and fresh or dried fruits can also help soften stools and relieve constipation.

Stool Softeners

Stool softeners like docusate sodium add moisture to the stool, making it easier to pass. They are generally considered safe for short-term use.

Prescription Drugs

If over-the-counter treatments are ineffective, a doctor may prescribe stronger medications. These can include prescription-strength laxatives or prokinetic agents. Lubiprostone, for example, increases fluid in the digestive tract, reducing abdominal pain, softening stools, and increasing bowel movements. Linaclotide and plecanatide are prescribed for irritable bowel syndrome with constipation or long-lasting constipation of unknown causes.

Probiotics

Probiotics can help improve the balance of gut bacteria and promote regular bowel movements. Prebiotics, found in foods like bananas and oatmeal, can also be beneficial for digestive issues.

Traditional Remedies

Herbal teas, prunes, or prune juice have mild laxative effects and can help relieve constipation.

Lifestyle Changes

Making certain lifestyle changes can help prevent and treat constipation. These include increasing fiber intake, staying hydrated, engaging in regular physical activity, and establishing a regular bathroom routine. Additionally, it is important to not ignore the urge to have a bowel movement.

Preventing constipation

Milk of magnesia is a popular over-the-counter medication for constipation relief. It is a type of saline laxative that works by drawing water into the bowel, softening the stool, and making it easier to pass. It can start working within 30 minutes to 6 hours, providing quick relief from constipation.

While milk of magnesia can be an effective short-term solution, it is important to address the underlying causes of constipation to prevent it from becoming a chronic issue. Here are some ways to help prevent constipation:

Increase Fibre Intake

Fibre-rich foods such as fruits, vegetables, whole grains, nuts, and seeds can improve gut function and promote regular bowel movements. It is recommended that women consume about 25 grams of fibre per day, while men should aim for 30 grams.

Drink Plenty of Fluids

Staying well-hydrated is crucial for preventing constipation. Aim for about 2 litres of fluids per day, mostly water. Drinking warm fluids in the morning, such as tea or coffee, can help stimulate digestion. Prune juice is also known to have a laxative effect.

Engage in Regular Physical Activity

Physical activity, even light exercise like walking, can help stimulate bowel movements. It is recommended to get at least 30 minutes of moderate exercise per day.

Establish a Regular Bathroom Routine

Try to go to the bathroom when you feel the urge and avoid delaying or ignoring it. Using a toilet stool can help adjust your body position to make it easier to pass stool.

Avoid Common Causes of Constipation

Common causes of constipation include a low-fibre diet, dehydration, sedentary lifestyle, certain medications, and underlying health conditions. Addressing these factors can help reduce the likelihood of developing constipation.
