Special warnings and precautions for use
Individual benefit/risk assessment
The risk of therapy in case of life-threatening thromboembolic events, in particular that of
haemorrhages, must be weighed against the anticipated benefit in cases such as:
• recent severe gastrointestinal bleeding, e.g. active peptic ulcer
• risk of severe local haemorrhage, e.g. in case of aortography by lumber route
• recent trauma and cardiopulmonary resuscitation
• invasive operations, e.g. recent intubation
• puncture of non-compressible vessels, intramuscular injections
• recent delivery, abortion
• diseases of the urinogenital tract with existing or potential sources of bleeding
(implanted bladder catheter)
• known septic thrombotic disease
• severe atherosclerotic vessel degeneration, cerebrovascular diseases
• cavernous pulmonary diseases, e.g. open tuberculosis
• mitral valve defects or atrial fibrillation
Because of the increased likelihood of resistance due to antistreptokinase antibodies,
repeat treatment with Streptase or streptokinase containing products may not be effective if
administered more than 5 days, particularly between 5 days and 12 months after initial
Likewise, the therapeutic effect may be reduced in patients with recent streptococcal infections
such as streptococcal pharyngitis, acute rheumatic fever and acute glomerulonephritis.
Infusion rate and corticosteroid prophylaxis
At the beginning of therapy, a fall in blood pressure, tachycardia or bradycardia (in individual
cases reaching as far as shock), are commonly observed. Therefore, at the beginning of
therapy the infusion should be performed slowly.
Corticosteroids can be administered prophylactically to reduce the likelihood of infusionrelated allergic reactions.
Pre-treatment with heparin or coumarin derivatives
If the patient is under active heparinization, it should be neutralised by the administration of
protamine sulphate before the start of the thrombolytic therapy. The thrombin time should
not be more than twice the normal control value before thrombolytic therapy is started. In
patients previously treated with coumarin derivatives, the INR (International Normalized
Ratio) must be less than 1.3 before starting the streptokinase infusion.
Should an arterial puncture be necessary during intravenous therapy, upper extremity vessels
are preferable. After the puncture, pressure should be applied for at least 30 minutes by a
compression bandage and the puncture site should be checked frequently for evidence of
Streptase is not indicated for restoration of patency of intravenous catheters.

The following information is intended for medical or healthcare professionals
Intravascular dissolution of thrombi and emboli:
– massive deep vein thrombosis with risk of gangrene
– acute massive pulmonary embolism
– acute, sub-acute and chronic (not older than 6 weeks) occlusive arterial diseases with limb
– central retinal artery or vein occlusion (arterial occlusions not older than 8 hours, venous
occlusion not older than 10 days)
Note: No statement on therapy outcome can be made for administration beyond the time
windows indicated above.
Posology and method of administration
The administration of Streptase may be by systemic intravenous infusion or by local intraarterial catheter-directed infusion during arteriography.
Note: When thrombolytic therapy is necessary and a high antibody concentration against
streptokinase is present, or when recent streptokinase therapy has been given (more than
5 days and less than one year previously), homologous fibrinolytics should be used.
Deep vein thrombosis
Streptase should be administered by intravenous infusion into a peripheral vein using the
following standard dose regimen: an initial dose of 250,000 IU Streptase infused over
30 minutes, followed by a maintenance dose of 100,000 IU per hour for 72 hours.
Streptase should be administered by intravenous infusion into a peripheral vein using
preferably a short infusion of 1,500,000 IU Streptase over 1 – 2 hours.
Alternatively, the standard dose regimen can be used: an initial dose of 250,000 IU Streptase
infused over 30 minutes, followed by a maintenance dose of 100,000 IU per hour for
Occlusive peripheral arterial diseases
Streptase should be administered by local intra-arterial catheter-directed infusion using one
of the following dose regimens:
• Stepwise infusion: 1,000 to 2,500 IU Streptase in intervals of 3 to 5 minutes for a maximum
duration of 10 hours and a total maximum dose of 250,000 IU.
• Prolonged continuous low-dose infusion (using an infusion pump): 5,000 to 10,000 IU
Streptase per hour for a maximum of 5 days.
A percutaneous transluminal angioplasty can be performed simultaneously, if necessary.
Alternatively, in case of difficult arterial access or multiple occlusions, the standard
intravenous dose regimen can be used: an initial dose of 250,000 IU Streptase infused over
30 minutes, followed by a maintenance dose of 100,000 IU per hour for a maximum of
Occlusion of central retinal vessels
Streptase should be administered by intravenous infusion into a peripheral vein using the
standard dose regimen: an initial dose of 250,000 IU Streptase infused over 30 minutes,
followed by a maintenance dose of 100,000 IU per hour for 12 hours.
The safety and efficacy of Streptase have not been sufficiently established in children. Due to
low levels of plasminogen in newborns and in children with acquired plasminogen
deficiency and due to the potential of streptokinase for allergic/anaphylactic reactions, its use
is not recommended in neonates, infants and children.
Control of therapy
Before commencing thrombolytic therapy, it is desirable to obtain a thrombin time (TT),
activated partial thromboplastin time (aPTT), haematocrit and platelet count to obtain the
haemostatic status of the patient.
If heparin has been given, it should be discontinued and the TT or aPTT should be less than
twice the normal control value before thrombolytic therapy is started. In patients previously
treated with coumarin derivatives, the INR (International Normalised Ratio) should be below
1.7 before starting therapy with streptokinase.
During the infusion, decreases in the plasminogen and fibrinogen level and an increase in the
level of fibrin degradation products (FDP) (the latter two serving to prolong the clotting times
of coagulation tests) will generally confirm the existence of a thrombolytic state. Therefore
therapy can be monitored by performing the TT or aPTT approximately 4 hours after initiation
A 2 to 4 fold prolongation of the TT is considered as a sufficient anticoagulation protection
that should be aimed for. If the TT or any other parameter of lysis after 4 hours of therapy is
less than approximately 1.5 times the normal control value, Streptase should be discontinued
as excessive resistance to streptokinase is present.
As is usual with angiographies, heparin is administered, if necessary, prior to the angiography
as a safeguard against catheter-induced thromboses. The success of therapy can be
determined by the angiography. With a sufficient blood flow of more than 15 minutes the
therapy can be considered successful and then terminated.
After every course of streptokinase therapy a follow-up treatment with anticoagulants or
platelet aggregation inhibitors can be instituted as a prevention of rethromboses. With
heparin therapy, in particular, an increased risk of haemorrhage must be considered.
Streptase must not be used in case of severe allergic reactions to the product.
Because of the increased risk of haemorrhage under thrombolytic therapy, Streptase must not
be given in the following situations:
• existing or recent internal haemorrhages
• all forms of reduced blood coagulability, in particular spontaneous fibrinolysis and extensive
