If the medicine contains alcohol that is intoxicant, it will be impermissible to consume it, especially the said amount which is significantly high. Having said that, it is also worth to note in the book "al-Kafi" by Shaykh al-Kulayni the following narration on the authority of Imam Ja'far al-Sadiq, peace be upon him: "Every intoxicant is haram. Something that intoxicates only when consumed in large quantities, is also not allowed to be taken even in lesser quantity". You should look at other natural remedies or alternative medicines available on the market insh'Allah.

With prayers for your success.
