Brief Summary
The purpose of this study is to investigate whether routine administration of fluoxetine 20mg once daily in the 6 months initiated during the acute stroke improves the patient's functional outcome. EFFECTS is an investigator lead Sweden-based, multicenter, parallel group, double blind placebo controlled trial with broad entry criteria and follow up at 6 and 12 months. EFFECTS managed to recruit its anticipated numbers of 1,500 participants between 20th October 2014 and 28th June 2019. Data will be unblinded when the 6-months follow-up is completed, and the primary outcome is due to report on May 2020.

Eligibility Criteria
You may qualify if:
- Informed consent can only be obtained from a patient who according to the trial investigator is mentally capable of decision-making and who, after having received information and got answers to their questions, wants to participate in the trial.
- Brain imaging is compatible with intra cerebral hemorrhage or ischemic stroke.
- Randomization can be performed between 2 and 15 days after stroke onset and by the research group at the patient's local/emergency hospital.
- Persisting focal neurological deficit is present at the time of randomization severe enough to warrant treatment from the physicians and the patient's and relative's perspective.
You may not qualify if:
- Subarachnoidal hemorrhage except where secondary to a primary intracerebral hemorrhage.
- Unlikely to be available for follow up for the next 12 months e.g. no fixed home address.
- Unable to speak Swedish and no close family member available to help with follow up forms.
- Other life threatening illness (e.g. advanced cancer) that will make 12-month survival unlikely.
- History of epileptic seizures.
- History of allergy or contraindications to fluoxetine including: Hepatic impairment (S-ASAT/ALAT \> 3 upper normal limit) and renal impairment (S-Creatinine levels \> 180 micromol/L).
- Pregnant or breastfeeding, women of childbearing age not taking contraception. Minimum contraception is an oral contraceptive. An HCG-test is to be made prior randomization and after the end of trial medication.
- Previous drug overdose or attempted suicide.
- Already enrolled into a CTIMP.
- Current or recent (within the last month) depression requiring treatment with an SSRI antidepressant.
- Current use of medications which have serious interactions with fluoxetine Use of any mono-amino-oxidase inhibitor (MAOI) during the last 5 weeks. Co-administration of Fluoxetine and a mono-amino-oxidase inhibitor (MAOI) may result in life threatening interactions. Therefore, patients on MAOI are ineligible for the EFFECTS trial. Also, any patient in need of treatment with a MAOI must stop their trial treatment for at least 5 weeks before commencing the MAOI, or to be treated as in-patients by a psychiatrist.

Three trial investigator teams have collaboratively developed a core protocol for Fluoxetine after stroke. Minor variations have been tailored to the national setting in the UK (FOCUS), Australia and New Zealand (AFFINITY) and Sweden (EFFECTS). Each trial is run and funded independently and will report its own results. A prospectively planned individual patient data meta-analysis of all three trials will subsequently provide the most precise estimate of the overall effect of fluoxetine after stroke and establish whether any effects differ between trials and subgroups of patients.
