Hydralazine causes dilation of the walls of blood vessels and is sometimes used to treat hypertension.
Interaction
Substance: Vitamin B6
Effect: Supplementation Likely Helpful
Hydralazine is known to deplete the blood of vitamin B 6. Taking B 6 supplements may prevent or reverse side effects of the medication.1,2
Interaction
Substance: Coenzyme Q10 (CoQ10)
Effect: Supplementation Possibly Helpful
There is some evidence that hydralazine might impair the body's ability to manufacture the substance coenzyme Q 10 (CoQ 10).3 This suggests (but definitely does not prove) that taking CoQ 10 supplements may produce a beneficial effect.
Interaction
Substance: Coleus forskohlii
Effect: Theoretical Interaction
The herb Coleus forskohlii relaxes blood vessels and might have unpredictable effects if combined with hydralazine.
