What is Hydralazine?

Hydralazine is a medication used to treat high blood pressure. It is a vasodilator, which means it relaxes the blood vessels and allows blood to flow more easily through them. Hydralazine is available as a tablet, an injection, or as a solution for intravenous infusion. The usual starting dose is 25 mg three times daily.

What are the different types of Hydralazine?

Hydralazine comes in many different forms and doses. The most common hydralazine dose is 25 mg, but it also comes in 10, 50, and 100 mg tablets. It is also available as an injection, which is usually given in a hospital setting.

What are the side effects of Hydralazine?

There are a few potential side effects of hydralazine that medical professionals should be aware of. These include:
- Low blood pressure: This is the most common side effect and can occur within minutes after taking a dose of hydralazine. It is important to monitor blood pressure closely when starting hydralazine and adjust the dosage as needed.
- Headache: This is also a common side effect, especially during the first week or two of treatment. 
- Nausea and vomiting: These may occur, especially at higher doses of hydralazine. 
- Dizziness: This can occur due to low blood pressure and can be aggravated by standing up too quickly. Be sure to take it slow when getting up from a lying or sitting position.
- Rash: A rash may develop in some people taking hydralazine.

How to take Hydralazine properly

It is important to take hydralazine exactly as prescribed by your healthcare provider. The usual starting dose is 10 mg three times a day. Your healthcare provider may increase your dose if needed. The maximum recommended dose is 200 mg per day.

If you miss a dose of hydralazine, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time.

Hydralazine should be taken on an empty stomach or at least 1 hour before or 2 hours after a meal. To reduce flushing (hot flashes), avoid foods and beverages that are high in histamine, such as coffee, tea, chocolate, aged cheese, and red wine.

Drink plenty of water while taking hydralazine to keep your urine output high and help prevent kidney damage. Avoid becoming overheated or dehydrated during exercise or in hot weather.

As medical professionals, it is important to be aware of the proper dosages and potential side effects associated with taking this medication.
