Vitamin B6
Supplementation Likely Helpful

Hydralazine is known to deplete the blood of vitamin B 6. Taking B 6supplements may prevent or reverse side effects of the medication.1,2

Coenzyme Q10 (CoQ10)
Supplementation Possibly Helpful

Coleus forskohlii
Theoretical Interaction

The herb Coleus forskohlii relaxes blood vessels and might have unpredictable effects if combined with hydralazine.
