Can I take 90 and Sumatriptan together?

Why this happens

Both St John's Wort and sumatriptan increase the levels or activity of serotonin in the brain. St John's Wort prevents serotonin from being reabsorbed, while sumatriptan mimics serotonin to stop a migraine. When used together, the effect is 'additive', meaning the serotonin levels can rise to a dangerous level.

You should not take St John's Wort if you are using sumatriptan. If you are already taking both, speak to your doctor or pharmacist before stopping, as they can advise you on how to do so safely. If you experience any symptoms of serotonin syndrome, such as confusion, sweating, or a racing heart, seek medical help immediately.
