Hello there.
It might not cause any harmful effects as such because it's a multivitamin supplement.
If it was any other medicine like antibiotics or others, it could have caused certain problems.
Before the expiry date, the medicines will have good efficacy.
After expiry date, the efficacy just decreases.
And it may not work.
If you experience any symptoms, Consult a nearest physician ASAP.
