1. What Dynastat is and what it is used for

Dynastat contains the active substance parecoxib.
Dynastat is used for the short-term treatment of postoperative pain in adults.
It belongs to a group of medicines known as COX-2 inhibitors (short for cyclooxygenase-2 inhibitors).
Pain and inflammation are sometimes caused by certain substances produced by the human body called prostaglandins.
Dynastat works by reducing the levels of these prostaglandins.

2. What you should know before taking Dynastat

Do not use Dynastat

  • if you are allergic to parecoxib or to any of the other ingredients of this medicine (listed in section 6).
  • if you have had a severe allergic reaction (particularly a severe skin reaction) to any medicine
  • if you have had an allergic reaction to a group of medicines called “sulfonamides” (for example, certain antibiotics used to treat infections)
  • if you currently have an active gastric or intestinal ulcer or gastrointestinal bleeding
  • if you have had an allergic reaction to acetylsalicylic acid (aspirin) or to other non-steroidal anti-inflammatory drugs (NSAIDs) (e.g. ibuprofen) or to COX-2 inhibitors. Reactions after taking this medicine may include breathing difficulties (bronchospasm), nasal congestion, itching, skin rash, or swelling of the face, lips, or tongue, other allergic reactions, or nasal polyps
  • if you are in the last three months of pregnancy
  • if you are breastfeeding
  • if you have severe liver disease
  • if you have inflammatory bowel disease (ulcerative colitis or Crohn’s disease)
  • if you have heart failure
  • if you are about to undergo heart surgery or surgery on the arteries (including coronary artery surgery)
  • if you have established heart disease and/or cerebrovascular disease, for example if you have had a heart attack, stroke, transient ischaemic attack (TIA), or blockages in the blood vessels of the heart or brain, or if you have undergone a procedure to remove or bypass these blockages
  • if you have or have had circulation problems (peripheral arterial disease)

If any of these apply to you, you must not be given the injection. Inform your doctor or nurse immediately.

Warnings and precautions

Do not use Dynastat if you have an active gastric or intestinal ulcer or gastrointestinal bleeding
Do not use Dynastat if you have severe liver disease

Talk to your doctor or nurse before using Dynastat:

  • If you have previously had a gastric or intestinal ulcer, gastrointestinal bleeding, or perforation
  • If you have ever had a skin reaction (e.g. rash, hives, wheals, blisters, red spots) to any medicine
  • If you are taking acetylsalicylic acid (aspirin) or other non-steroidal anti-inflammatory drugs (NSAIDs) (e.g. ibuprofen)
  • If you smoke or drink alcohol
  • If you have diabetes
  • If you have angina, blood clotting disorders, high blood pressure, or elevated cholesterol levels
  • If you are taking medicines that affect platelet aggregation
  • If you have fluid retention (edema)
  • If you have liver or kidney disease
  • If you are dehydrated – this may occur with diarrhoea, vomiting, or inability to take in fluids
  • If you have an infection, as this may mask fever (a sign of infection)
  • If you are taking medicines to reduce blood clotting (e.g. warfarin/warfarin-like anticoagulants or newer oral anticoagulants such as apixaban, dabigatran, and rivaroxaban)
  • If you are taking corticosteroids (e.g. prednisone)
  • If you are taking a class of medicines used to treat depression called selective serotonin reuptake inhibitors (SSRIs) (e.g. sertraline).

Dynastat may cause an increase in blood pressure or worsen pre-existing hypertension, which could lead to an increased risk of adverse effects related to heart conditions. During treatment with Dynastat, your doctor may wish to monitor your blood pressure.

Use of Dynastat may lead to potentially life-threatening skin reactions, and treatment must be discontinued at the first sign of skin rash, blisters, skin peeling, mucosal lesions, or any other sign of hypersensitivity. If you develop a skin rash or experience other signs or symptoms on the skin or mucous membranes (e.g. inside the cheeks or lips), contact a doctor immediately and inform them that you are taking this medicine.

Children and adolescents

Dynastat must not be used in children and adolescents under 18 years of age.

Other medicines and Dynastat

Tell your doctor or nurse if you are taking, have recently taken, or might take any other medicines. Sometimes medicines can interact with each other. Your doctor may reduce the dose of Dynastat or other medicines, or recommend you take different medicines. It is especially important that your doctor knows if you are taking:

  • Acetylsalicylic acid (aspirin) or other anti-inflammatory medicines
  • Fluconazole – used for fungal infections
  • ACE inhibitors, angiotensin II inhibitors, beta-blockers, and diuretics – used for high blood pressure and heart conditions
  • Cyclosporine or tacrolimus – used after organ transplants
  • Warfarin or other warfarin-like medicines – used to prevent blood clots, including newer agents such as apixaban, dabigatran, and rivaroxaban
  • Lithium – used to treat depression
  • Rifampicin – used for bacterial infections
  • Antiarrhythmics – used to treat irregular heartbeat
  • Phenytoin or carbamazepine – used in epilepsy
  • Methotrexate – used in rheumatoid arthritis and cancer
  • Diazepam – used for sedation and anxiety
  • Omeprazole – used to treat ulcers

Pregnancy, breastfeeding, and fertility

  • Dynastat must not be used during the last three months of pregnancy because it could harm the fetus or cause problems during delivery. It may cause kidney and heart problems in the fetus. It could affect your tendency and that of the unborn child to bleed and may cause delayed or prolonged labour. Dynastat should not be used during the first six months of pregnancy unless absolutely necessary and under medical advice. If you need to take it during this period or while trying to become pregnant, the lowest possible dose for the shortest possible time should be used. If taken for more than a few days from the 20th week of pregnancy onwards, Dynastat may cause kidney problems in the fetus, which can lead to low levels of amniotic fluid (the fluid surrounding the fetus) (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the unborn child’s heart. If treatment is needed for more than a few days, your doctor may recommend additional monitoring.
  • If you are breastfeeding, you must not take Dynastat, as small amounts of Dynastat will pass into breast milk.
  • NSAIDs, including Dynastat, may make it more difficult to conceive. Inform your doctor if you are planning a pregnancy or are having difficulty becoming pregnant.

If you are pregnant, think you may be pregnant, are planning to become pregnant, or are breastfeeding, ask your doctor or nurse for advice before taking this medicine.

Driving and using machines

If you feel dizzy or experience fatigue after the injection, do not drive or operate machinery until you feel better.

Dynastat contains sodium

This medicine contains less than 1 mmol (23 mg) of sodium per mL, i.e. essentially ‘sodium-free’.

3. How to use Dynastat

Dynastat will be administered to you by a doctor or a nurse. They will dissolve the powder before injecting the solution into your vein or muscle. The injection may be given rapidly and directly into a vein or into an existing intravenous line (a thin tube leading into a vein), or it may be administered slowly and deeply into the muscle. Dynastat may only be used for short periods and solely for pain relief.

The normally recommended initial dose is 40 mg.
A subsequent dose of 20 mg or 40 mg may be administered 6 to 12 hours after the first dose.
You must not be given more than 80 mg within 24 hours.
Some people may require lower doses:

  • People with liver problems
  • People with severe kidney problems
  • Patients over 65 years of age weighing less than 50 kg
  • People being treated with fluconazole

If Dynastat is used together with strong painkillers (called opioid analgesics) such as morphine,
the dose of Dynastat will be the same as stated above.
If you are given more Dynastat than you should, side effects that have been reported with recommended doses may occur.
If you have any doubts about how to use this medicine, consult your doctor or nurse.

More detailed information on this medicine is available on the European Medicines Agency website: https://www.ema.europa.eu

The following information is intended exclusively for healthcare professionals.

Dosage – The recommended dose is 40 mg administered intravenously (i.v.) or
intramuscularly (i.m.). This may be followed every 6–12 hours as needed with doses of 20 mg or
40 mg, provided that the total daily dose does not exceed 80 mg. The intravenous bolus injection may
be administered rapidly and directly into a vein or into an existing intravenous line. The intramuscular
injection must be administered slowly and deeply into the muscle.
Clinical experience with Dynastat beyond three days is limited.
Since the cardiovascular risk of selective cyclooxygenase-2 (COX-2) inhibitors may increase with
dose and duration of exposure, treatment duration should be as short as possible and the lowest
effective daily dose should be used.
During post-marketing surveillance, cases of severe hypotension occurring immediately after
administration of parecoxib have been reported. Some of these occurred without other signs of
anaphylaxis. Physicians must be prepared to manage severe hypotension.
Administration is performed via intramuscular (i.m.) or intravenous (i.v.) injection.
The i.m. injection must be administered slowly and deeply into the muscle; the i.v. bolus injection may
be administered rapidly and directly into a vein or into an existing intravenous line.
Administration routes other than intravenous or intramuscular
Administration routes (e.g. intra-articular, intrathecal) other than intravenous or intramuscular have
not been studied and must not be used.
Solvents for reconstitution
This medicinal product must not be mixed with other medicinal products. The product must be
reconstituted only with one of the following solutions:

  • Sodium chloride 9 mg/mL (0.9%) solution for injection/infusion
  • Glucose 50 mg/mL (5%) solution for infusion; or
  • Sodium chloride 4.5 mg/mL (0.45%) and glucose 50 mg/mL (5%) solution for injection/infusion

The following solvents must not be used for reconstitution:

  • The use of Ringer's lactate solution for injection or glucose 50 mg/mL (5%) in Ringer's lactate solution for injection for reconstitution of parecoxib is not recommended, as it causes precipitation of parecoxib.
  • The use of sterile water for injection is not recommended because the resulting solution is not isotonic.

Procedure for reconstitution
An aseptic technique must be used for reconstitution of lyophilized parecoxib (as sodium parecoxib).
20 mg vial: Remove the removable purple overcap until the central portion of the rubber stopper of the 20 mg parecoxib vial is visible. Using a sterile needle and syringe, withdraw 1 mL of a suitable solvent and insert the needle through the central portion of the rubber stopper to transfer the solvent into the 20 mg parecoxib vial.
40 mg vial: Remove the removable purple overcap until the central portion of the rubber stopper of the 40 mg parecoxib vial is visible. Using a sterile needle and syringe, withdraw 2 mL of a suitable solvent and insert the needle through the central portion of the rubber stopper to transfer the solvent into the 40 mg parecoxib vial.
Completely dissolve the powder by gently rotating the vial and inspect the reconstituted product before use.
The reconstituted solution must not be used if discolored, cloudy, or if particulate matter is present.
The entire contents of the vial must be withdrawn for single administration. If a dose less than 40 mg
is required, the excess medicinal product must be discarded.
Compatibility of intravenous solution
Dynastat in solution with other medicinal products may cause precipitation; therefore, Dynastat must
not be mixed with other medicinal products, either during reconstitution or at the time of administration.
In patients requiring administration of another medicinal product via the same infusion line, the line
must be flushed before and after administration of Dynastat with a compatible solution.
After reconstitution with suitable solvents, Dynastat may be injected intravenously or intramuscularly,
or administered via intravenous lines containing:

  • Sodium chloride 9 mg/mL (0.9%) solution for injection/infusion
  • Glucose 50 mg/mL (5%) solution for infusion
  • Sodium chloride 4.5 mg/mL (0.45%) and glucose 50 mg/mL (5%) solution for injection/infusion; or
  • Ringer's lactate solution for injection

Administration of the reconstituted product via the same infusion line with
glucose 50 mg/mL (5%) in Ringer's lactate solution or other intravenous fluids not listed in this section
is not recommended, as it may cause precipitation of parecoxib.
The solution is for single use only and must not be stored in a refrigerator or freezer.
The chemical and physical stability of the reconstituted solution, which must not be refrigerated or
frozen, has been demonstrated for up to 24 hours at 25°C. Therefore, 24 hours should be considered
the maximum shelf-life of the reconstituted product. However, due to the significant risk of microbiological
contamination for injectable products, the reconstituted solution should be used immediately unless
reconstitution is performed under validated and controlled aseptic conditions. If such conditions are
not met, the storage time and conditions prior to use are the responsibility of the user and should
normally not exceed 12 hours at 25°C.

More detailed information on this medicinal product is available on the website of the European Medicines Agency: https://www.ema.europa.eu

The following information is intended exclusively for healthcare professionals.

Dosage – The recommended dose is 40 mg, administered intravenously (i.v.) or
intramuscularly (i.m.). This may be followed by doses of 20 mg or 40 mg every 6–12 hours as needed,
provided that the total daily dose does not exceed 80 mg. The intravenous bolus injection may be given
rapidly and directly into a vein or into an existing intravenous line. The intramuscular injection must be
administered slowly and deeply into the muscle.
Clinical experience with Dynastat beyond three days is limited.
Since the cardiovascular risk of selective cyclooxygenase-2 (COX-2) inhibitors may increase with dose
and duration of exposure, treatment duration should be as short as possible and the lowest effective daily
dose should be used.
During post-marketing surveillance, cases of severe hypotension occurring immediately after
administration of parecoxib have been reported. Some of these occurred without other signs of
anaphylaxis. Physicians must be prepared to manage severe hypotension.
Administration is performed via intramuscular (i.m.) or intravenous (i.v.) injection.
The i.m. injection must be administered slowly and deeply into the muscle, and the i.v. bolus injection
may be administered rapidly and directly into a vein or into an existing intravenous line.

Administration routes other than intravenous or intramuscular
Administration routes (e.g., intra-articular, intrathecal) other than intravenous or intramuscular have
not been studied and must not be used.

Solvents for reconstitution
This medicinal product must not be mixed with other medicinal products. The product must be
reconstituted only with one of the following solutions:

  • Sodium chloride 9 mg/mL (0.9%) solution for injection/infusion
  • Glucose 50 mg/mL (5%) solution for infusion; or
  • Sodium chloride 4.5 mg/mL (0.45%) and glucose 50 mg/mL (5%) solution for injection/infusion

The following solvents must not be used for reconstitution:

  • Lactated Ringer’s solution for injection or glucose 50 mg/mL (5%) in lactated Ringer’s solution for injection are not recommended for reconstitution of parecoxib, as they cause precipitation of parecoxib.
  • Sterile water for injection is not recommended because the resulting solution is not isotonic.

Procedure for reconstitution
An aseptic technique must be used for reconstitution of lyophilized parecoxib (as parecoxib sodium).
40 mg vial: Remove the purple aluminum overcap until the central portion of the rubber stopper of the
40 mg parecoxib vial is visible. Using a sterile needle and syringe, withdraw 2 mL of a suitable solvent
and insert the needle through the central portion of the rubber stopper to transfer the solvent into the
40 mg parecoxib vial.
Completely dissolve the powder by gentle swirling and inspect the reconstituted product before use.
The reconstituted solution must not be used if it is discolored, cloudy, or if particulate matter is present.
The entire content of the vial must be withdrawn for single administration. If a dose less than 40 mg is
required, the excess medicinal product must be discarded.

Compatibility of intravenous solution
Dynastat in solution with other medicinal products may cause precipitate formation; therefore, Dynastat
must not be mixed with other medicinal products, either during reconstitution or at the time of
administration. In patients requiring administration of another medicinal product via the same infusion
line, the line must be flushed before and after Dynastat administration with a compatible solution.

After reconstitution with suitable solvents, Dynastat may be injected intravenously or intramuscularly,
or administered solely via intravenous lines containing:

  • Sodium chloride 9 mg/mL (0.9%) solution for injection/infusion
  • Glucose 50 mg/mL (5%) solution for infusion
  • Sodium chloride 4.5 mg/mL (0.45%) and glucose 50 mg/mL (5%) solution for injection/infusion; or
  • Lactated Ringer’s solution for injection

Administration of the reconstituted product in the same infusion line with glucose 50 mg/mL (5%) in
lactated Ringer’s solution or other intravenous fluids not listed in this section is not recommended, as
it causes precipitation of parecoxib.

The solution is for single use only and must not be refrigerated or frozen.
Chemical and physical stability of the reconstituted solution, which must not be refrigerated or frozen,
has been demonstrated for up to 24 hours at 25°C. Therefore, 24 hours should be considered the
maximum shelf-life of the reconstituted product. However, due to the importance of microbiological
infection risk for injectable products, the reconstituted solution should be used immediately unless
reconstitution was performed under validated and controlled aseptic conditions.
If such conditions are not met, the storage times and conditions prior to use are the responsibility of the
user and should normally not exceed 12 hours at 25°C.
