Dulcolax liquid

Dulcolax Pico liquid 5mg/5ml is a liquid solution used to provide rapid relief from symptoms of constipation. It is fruit flavoured and liquid, making it a useful option for those who experience difficulty swallowing other medicines. Dulcolax solution is also sometimes used to empty the bowel before certain radiological procedures.

Dulcolax Pico Liquid 5mg/5ml is a rapidly acting liquid solution for alleviating constipation.

Every 5ml of Dulcolax solution contains 5mg of sodium picosulfate. Sodium picosulfate is a stimulant laxative. This means it stimulates the bowel to empty itself, alleviating constipation and helping the bowel return to regular function.

The way sodium picosulfate does this is by stimulating nerves that line the walls of the colon and rectum. This stimulation encourages the intestinal wall muscles to contract more intensely and regularly, which is how the contents of the intestine are moved through the colon to the rectum. Thus, the bowels can be emptied as normal.

Sodium picosulfate can provide relief from constipation overnight in a predictable manner.

Sodium picosulfate does not start working until it reaches the right area of the gut, as it is dormant until activated by naturally occurring bacteria that live in the colon.

The effects of Dulcolax Pico Liquid should occur within six to twelve hours of taking a dose. Dulcolax should be used at night time so that the effects occur in the following morning.

Dulcolax Pico Liquid is a fruit flavoured liquid solution for providing relief from constipation overnight. Dulcolax also helps the bowel return to normal regulated function by providing stimulation to both the colon and rectum.


Dulcolax is sugar-free, fruit flavoured, and provides relief from constipation overnight.

Safety Warning

If you suffer from persistent abdominal pain, or need the use of laxatives every day, consult with a doctor.

Keep this product away from children.

Do not use this medicine if you are experiencing abdominal pain combined with sickness and vomiting. This indicates a more serious condition and you should consult with a doctor.

Do not use this medicine for more than five days in a row without first consulting with a doctor.

Use of laxatives over a prolonged period of time can have adverse effects, such as electrolyte imbalance, hypokalaemia (low levels of potassium in the blood) or chronic diarrhoea. These effects are more likely if you are also using diuretics or steroids. Additionally, using laxatives often can cause the gut to rely on them, making constipation more frequent.

Dulcolax Pico Liquid contains alcohol and so care should be taken by people who are pregnant or breastfeeding, or suffering from liver disease, epilepsy or alcoholism.

Pharmacists Tip

Sometimes constipation can be very painful. This pain can be reduced through use of a painkiller such as ibuprofen, aspirin, or paracetamol. Do not use painkillers that contain codeine as they can cause the side effect of constipation.

This medicine should be used for:

Blockage in the gut (ileus or intestinal obstruction)

Acute attacks of Crohn’s disease, ulcerative colitis or other inflammatory bowel diseases

Appendicitis or other abdominal conditions that require surgery


Abdominal pain combined with sickness and vomiting. This indicates a more serious condition and you should consult with a doctor.

This medicine should not be used by children under 10 years old, unless instructed otherwise by a doctor.

Do not use this medicine if you suffer allergic reactions in response to any of its ingredients. If you have previously suffered an allergic reaction, inform a doctor or pharmacist. If this medicine induces an allergic reaction, stop using it and consult with a doctor or pharmacist immediately.

It is important that bowel movements proceed in a normal and regular manner. However, ‘normal and regular’ can mean different things for different people. While some people have a bowel movement daily, this is not the case for everyone. However often you have bowel movements, it is important that a regular pattern is followed. Constipation occurs when certain muscle action in the bowel is slowed down, meaning intestinal contents are not expelled from the body easily. Often, the cause of constipation is unknown. Some associated causes are sudden dietary changes, loss of bowl muscle tone in older people, pregnancy, certain medicines (such as codeine or morphine), lack of exercise. Constipation can be incredibly uncomfortable. It can cause symptoms such as a feeling of heaviness or bloating, or headaches. The following tips are recommended to avoid constipation from occurring:

Drink enough water and avoid dehydration

Eat a balanced diet, including enough fresh fruit and vegetables

Stay fit and maintain regular exercise

Empty your bowels when the body tells you that it is time to do so.

*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

Adults over 18 years:

Take one to two tablets at the night. 

Initially take one tablet and then increase to two as required.

Read the label carefully.

Do not exceed the stated dose.

Not everyone will experience side effects when they take medication, however if you do they can include:

If you are concerned about these effects, or if the product affects you in any other way, stop using it and talk to your doctor or pharmacist.

Frequently Asked Questions

  • What time during the day is best to take Dulcolax Tablets?

    It may be best to take Dulcolax tablets an hour or so before going to bed, as they need 6 to 12 hours to work on your system.

  • How many Dulcolax Tablets do you take?

    Children over 12 years of age and adults can take up to 3 tablets in a single daily dose for a maximum of 7 days. When you take this medication for the very first time, start with taking no more than 2 tablets in a single dose. Take them about an hour before going to bed and this should produce a bowel movement, upon arising the next morning. You can increase your dosage to 3 tablets, if needed.

  • Can I take Dulcolax Tablets on a continuous basis?

    You need to take up to 3 a day for a maximum of 7 days. For a longer period, you must first consult your doctor or a pharmacist.

  • Do I take the tablets with meals?

    This medication can be taken at any time but not within one hour of having consumed dairy foods or antacids.

  • How does this medication work?

    It stimulates the intestines, to bring about a bowel movement. The special enteric coating gives the medication time to reach the intestines, before releasing the active ingredient.

  • Can I chew or crush the tablets?

    Dulcolax Tablets have a special coating, which allows the tablets to reach the right place before taking effect, so they must always be swallowed whole and never broken or chewed.

  • Is it okay to take Dulcolax after having consumed milk or dairy products?

    No. Wait one hour after having consumed such foods, or having taking any indigestion medication, before taking Dulcolax tablets, or the special coating on the tablets will dissolve and the active ingredient will be released in the body before having reached the intestines. Such an early release can lead to cramping or vomiting.

    Dulcolax Tablets help restore your natural rhythm and give effective relief from constipation. This medication gives predictable overnight relief.

  • Can I take Dulcolax Tablets alongside prescription drugs, or if I have some other medical condition?

    If you take any other prescription or non-prescription medication, any vitamins or herbal remedies, or if you have another health problem, always speak with your doctor or a pharmacist, to ascertain whether taking Dulcolax Tablets will be right for you.

  • Can I use different Dulcolax products together?

    If you feel as though you may need more than one Dulcolax® product, first consult your doctor or a pharmacist.

  • Can I break a Dulcolax Tablet in half?

    Dulcolax Tablets should never be broken and should always be swallowed whole.

  • Can pregnant women take Dulcolax?

    If you are pregnant, speak with your doctor or pharmacist first, so as to determine if Dulcolax is right for you, as there isn't yet sufficient well-controlled studies to confirm its effects on pregnancy.
