Hydralazine belongs to the class of medications called vasodilators. It is used alone or with other medications to reduce blood pressure. It works to lower blood pressure by relaxing veins and arteries.

Mint Hydralazine may be available under multiple brand names and/or in several different forms. Any specific brand name of Mint Hydralazine may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Mint Hydralazine may not be used for all of the conditions discussed here.

Your doctor may have suggested Mint Hydralazine for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Mint Hydralazine, speak to your doctor. Do not stop taking Mint Hydralazine without consulting your doctor.

Do not give Mint Hydralazine to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Mint Hydralazine if their doctor has not prescribed it.

The dose of hydralazine is based on the individual and depends on the condition being treated and the person's response to the medication. The starting dose of hydralazine tablets is 10 mg taken 4 times a day for the first 2 to 4 days. Depending on how well it is working for you and how well it is tolerated, your doctor will gradually increase the dose. The usual recommended maintenance dose of hydralazine to treat high blood pressure varies from 10 mg to 50 mg 4 times daily. The dose should not be increased over 100 mg per day without further testing by your doctor to determine your acetylator phenotype.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Mint Hydralazine exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Mint Hydralazine at room temperature, protect it from heat and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
