What are hydralazine 50 mg film-coated tablets?
Hydralazine is a medication primarily used to manage high blood pressure. The 50 mg film-coated tablet form is one way the medicine may be prescribed for blood pressure control.
In the original content, hydralazine is also described as being used in hypertension and in some cases during hypertensive crises. The exact use depends on the prescriber’s instructions and the patient’s clinical situation.
How hydralazine works
Hydralazine works by relaxing the blood vessels. This lowers resistance to blood flow and can reduce blood pressure. By easing the workload on the heart, it may help improve overall blood pressure control.
The original content notes that hydralazine acts mainly on arteries rather than veins. It also mentions a possible role in stimulating nitric oxide, which supports blood vessel relaxation.

The source content advises sharing your full medical history with a healthcare provider, especially if you have heart conditions, kidney disease, or autoimmune disorders.
It also notes that people with a known allergy to hydralazine or related compounds should avoid it. Follow-up appointments are important so the prescriber can review how the medicine is working and whether any changes are needed.
The original content also mentions avoiding alcohol because it may worsen dizziness or low blood pressure.
Pregnancy and breastfeeding
According to the original content, hydralazine is often used during pregnancy when needed for hypertension or preeclampsia. It also states that hydralazine is considered safe during breastfeeding because only small amounts pass into breast milk.
