Saline Laxative Enemas: Procedure, Benefits, And Risks

A saline laxative enema is a fast-acting over-the-counter medication used to relieve occasional constipation. It works by pulling water into the intestines to soften the stool and stimulate bowel movement. The enema is inserted rectally and usually produces a bowel movement within 1 to 15 minutes. It is important to follow the instructions carefully and not to use more than one enema in a 24-hour period to avoid harmful side effects.

How does a saline laxative enema work?

A saline laxative enema is a fast-acting treatment for occasional constipation. It is a type of osmotic laxative, which works by drawing water into the intestines to hydrate and soften stool, making it easier to pass. This process usually stimulates a bowel movement within 1 to 15 minutes.

Saline laxative enemas are available over the counter and are suitable for adults and children over 12 years old. The typical dose is the contents of one adult bottle inserted into the rectum as a single dose. The enema should not be used more than once in a 24-hour period and should not be used for more than three consecutive days without consulting a doctor.

To use a saline laxative enema, follow the instructions on the package. First, wash your hands and remove the protective shield from the enema tip. Then, lie on your left side with your knees bent or kneel and lean forward, resting the left side of your face on a flat surface. Gently insert the enema tip into the rectum, pointing it towards the navel. Squeeze the bottle to release the solution, but do not empty it completely as this may cause discomfort. Remove the tip and stay in position for up to 5 minutes until you feel the urge to have a bowel movement.

Saline laxative enemas are not suitable for everyone. They should not be used by children under 2 years old. Additionally, people with certain medical conditions, such as kidney disease, heart problems, or dehydration, should consult a doctor before using this product. It may also be unsafe for those on a sodium-restricted diet or experiencing sudden changes in bowel habits.

How long does it take to work?

A saline enema is a fast-acting laxative that can be used to relieve constipation. It works by drawing water into the intestines, softening the stool, and making it easier to pass. The time it takes for a saline enema to work can vary, but it is generally very quick, often within just a few minutes.

Most people will experience relief from constipation within 1 to 5 minutes of administering a saline enema. However, it is recommended to stay near a toilet for about an hour after taking the enema, as you may need to use the bathroom more than once during that time.

The speed at which a saline enema works can depend on several factors, including the volume of the enema, the retention period, and the individual's body. It is important to follow the instructions on the enema kit carefully and not to exceed the recommended dosage. Taking more than one dose of a saline enema in a 24-hour period can be harmful and may cause serious side effects.

It is also important to note that saline enemas are not suitable for everyone. They should be avoided by people with kidney or heart conditions, as they can cause dehydration and electrolyte imbalances. If you are experiencing constipation and are considering using a saline enema, it is always best to consult your doctor first to ensure it is safe for you.

Who should not use a saline laxative enema?

A saline laxative enema is a medication used to relieve occasional constipation. It is important to note that this product is intended for rectal use only and should not be used for more than three days without consulting a doctor.

There are several groups of people who should not use a saline laxative enema without first seeking medical advice:

• Children under 2 years of age.
• Those with kidney disease.
• Those with heart problems.
• Those who are dehydrated or experiencing symptoms of dehydration, such as feeling thirsty, dizziness, vomiting, or decreased urination.

What are the side effects?

Saline laxative enemas are used to relieve constipation and typically work within 1 to 15 minutes. They are safe for adults and children over 12 years old, but there are some side effects to be aware of.

Firstly, it is important to note that using more than one saline laxative enema in 24 hours can be harmful. Do not use this product for more than three days without consulting a doctor. Additionally, if you have kidney disease, heart problems, or dehydration, or are experiencing abdominal pain, nausea, or vomiting, you should not use this product without first seeking medical advice.

Mild abdominal discomfort, cramps, or gas may occur as side effects. If these effects persist or worsen, consult a doctor or pharmacist. Saline laxative enemas can also cause diarrhoea, which, if it doesn't stop, can lead to dehydration, potentially causing serious side effects to the kidneys and heart. Contact your doctor if you notice any symptoms of dehydration, such as dry mouth, increased thirst, lack of tears, dizziness, or pale/wrinkled skin.

Other serious side effects include severe or persistent stomach/abdominal pain, bloody stools, rectal bleeding, mental/mood changes (such as confusion or unusual drowsiness), muscle weakness/spasm, and swelling of the hands/ankles/feet. Seek immediate medical help if you experience any very serious side effects, such as an irregular heartbeat or seizures.

Although rare, an allergic reaction to this medication may occur, with symptoms including a rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, and trouble breathing.

How should it be administered?

Saline laxative enemas are for rectal use only and should never be swallowed. They are used to relieve constipation and to clean the bowels before certain medical procedures. They are not suitable for children under 2 years old.

Before administering a saline enema, wash your hands. You should also drink plenty of clear fluids to prevent dehydration.

The recipient should lie on their left side with their knee bent, or kneel and lower their head and chest forward until the left side of their face is resting on a flat surface.

Remove the protective shield from the enema tip. Gently insert the enema tip into the rectum, pointing it towards the navel. Do not force the tip into the rectum as this could cause injury. Squeeze the bottle until the recommended amount of liquid is inside the rectum. You do not need to empty the bottle completely.

Remove the bottle tip from the rectum and stay in position for 1 to 5 minutes, or until you feel a strong urge to have a bowel movement.

If you do not feel the urge after 5 minutes, try to empty your bowel anyway. If no liquid comes out of the rectum after 30 minutes, contact a doctor as dehydration could occur.
