The risk is higher with 60 mg, which is why official guidance says treatment should generally start at 30 mg, with 60 mg considered only if 30 mg isn't effective and 30 mg is well tolerated. E European Medicines Agency (EMA) Avoid alcohol when taking it because alcohol can increase dizziness and fainting risk.
