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 Apo Hydralazine exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular dosing schedule.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

stop taking one of the medications,
change one of the medications to another,
change how you are taking one or both of the medications, or
leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Apo Hydralazine. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take Apo Hydralazine.

Blood tests: Rarely, Apo Hydralazine can decrease the number of neutrophils (a type of white blood cell that helps fight infection), red blood cells (which carry oxygen), and platelets (which help your blood to clot). Your doctor will do regular blood tests to monitor your blood cell levels while you are taking Apo Hydralazine.

Kidney Disease: Decreased kidney function can cause Apo Hydralazine to build up in the body, causing side effects. If you have decreased kidney function, discuss with your doctor how Apo Hydralazine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Apo Hydralazine, and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause Apo Hydralazine to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Apo Hydralazine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Apo Hydralazine, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Apo Hydralazine.

Low blood pressure: Some people taking hydralazine may experience sudden blood pressure drops when getting up from a sitting or lying position. These blood pressure drops could lead to dizziness, lightheadedness, and falls. If you experience this problem, try getting up more slowly. If it persists or if you faint, contact your doctor.

Lupus: Hydralazine may cause lupus-like symptoms (e.g., joint pain, fever, generalized rash). If these symptoms develop, contact your doctor immediately.

Pregnancy: Apo Hydralazine should only be used during pregnancy when the benefits outweigh the risks. If you become pregnant while taking Apo Hydralazine, contact your doctor immediately.

Breast-feeding: Apo Hydralazine passes into breast milk. If you are a breast-feeding mother and are taking hydralazine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using Apo Hydralazine have not been established for children.

Seniors: Seniors may be more sensitive to the blood-lowering effects of hydralazine. It should be used with more caution.
