How to take TEGLUTIK®

Follow all directions given to you by your doctor or pharmacist carefully.

If you do not understand the instructions in this leaflet, ask your doctor or pharmacist for help.

How much to use

The recommended dose is 100 mg a day (50 mg every 12 hours).

Do not take more than the dose your doctor has directed.

How to take TEGLUTIK®

10 mL of the oral suspension, containing 50 mg of riluzole, should be taken by mouth or via a Percutaneous Endoscopic Gastrostomy (PEG) every 12 hours, at the same time of the day each day (for example, in the morning and evening). The suspension is administered by means of graduated dosing syringe.

The oral suspension must be manually gently shaken for at least 30 seconds by rotating the bottle by 180° and the homogeneity should be visually verified.

Method of administration:

Open the bottle: press the cap and turn it anticlockwise (figure 1).

Take the syringe, remove the tip and insert the syringe in the adaptor opening (figure 2). Turn the bottle upside down (figure 3).

Fill the syringe with a small amount of suspension by pulling the plunger down (figure 3A), then push the piston upward in order to remove any possible bubble (figure 3B). Pull the piston down to the graduation mark corresponding to the quantity in milliliters (mL) prescribed by your doctor (figure 3C).

Turn the bottle the right way up (figure 4A). Remove the syringe from the adaptor (figure 4B).

  • Administer orally the whole content of the syringe. Dilution in water is not necessary.
  • Close the bottle with the plastic screw cap.
  • Wash the syringe with water only and re-assemble it with its tip cap once dried (figure 5).

For PEG administration, the tubing should be washed with 10 mL of water before and after administration of TEGLUTIK®.

When to take it

10 mL of the oral suspension should be taken by mouth every 12 hours, at the same time of the day each day (for example, in the morning and evening).

TEGLUTIK® should not be taken immediately before or after meals, especially meals which may contain food high in fat. TEGLUTIK® may not work as well if it is taken at the same time as your meals.

How long to take it

Do not stop taking TEGLUTIK® unless your doctor tells you to, even if you feel better.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not use a double dose to make up for the dose you missed.

If you are not sure what to do, ask your doctor or pharmacist.

If you use too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to the Accident and Emergency at your nearest hospital, if you think you or anyone else may have used too much TEGLUTIK® oral suspension. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Things to be careful of

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking TEGLUTIK®.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following:

  • stomach ache, nausea or vomiting
  • headache
  • joint stiffness
  • skin problems eg. rash, flaking skin
  • dizziness
  • sleepiness
  • weakness or loss of strength

  • If your skin becomes itchy or yellow or if you start to bleed or bruise easily. You may be developing a liver problem.

These are very serious side effects. You may need urgent medical attention or hospitalisation. All of these side effects are very rare.

As riluzole oral suspension is more rapidly absorbed than riluzole tablets, a slight increase in tiredness, dizziness, diarrhoea and transaminases cannot be excluded. If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet.

Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything that is making you feel unwell.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using TEGLUTIK®


Keep the oral suspension in the bottle, inside the box, until it is time to take it. If you take the oral suspension out of the box or bottle it may not keep well

Keep it in a cool dry place where the temperature stays below 25°C.

Do not store it or any other medicine in the bathroom or near a sink.

Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.

After first opening: the oral suspension should be used with 15 days.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking TEGLUTIK®, or it has passed its expiry date, ask your pharmacist what to do with any that are left over.
