Frequently asked questions

Is Alphadopa L Tablet safe?

Alphadopa L Tablet is generally considered a safe medicine if it is taken as directed by the doctor. The side effects that result with use of Alphadopa L Tablet occur during the first few weeks of treatment and disappear with time.

Why is Alphadopa L Tablet used in pregnancy?

It is important to appropriately treat high blood pressure in pregnancy. Studies have shown that poorly controlled high blood pressure in pregnancy can lead to an increased risk of certain birth defects, stillbirth, reduced growth of the baby within the womb, and premature birth. For some women with high blood pressure, treatment with Alphadopa L Tablet in pregnancy might be considered to be the best option. Your doctor is the best person to help you decide what is right for you and your baby.

Does Alphadopa L Tablet cause itching?

Yes, itchy skin, a rash or tingly scalp are common side effects of Alphadopa L Tablet. Speak to your doctor if the itchiness or rash gets worse or lasts for more than a week.

Is it safe to use Alphadopa L Tablet in patients with diabetes?

Diabetic patients while using Alphadopa L Tablet should regularly check the blood sugar levels. Alphadopa L Tablet may make it difficult to recognize the warning signs of low blood sugar such as shaking and a racing heartbeat. Consult your doctor if the blood sugar levels are reduced while taking Alphadopa L Tablet.

Does Alphadopa L Tablet affect heart rate?

Alphadopa L Tablet slows down your heart rate and makes it easier for your heart to pump blood around your body. Your doctor may regularly check your blood pressure and pulse (heart rate) during therapy to determine your response to the medicine.

What can happen if I stop taking Alphadopa L Tablet?

Do not stop taking Alphadopa L Tablet without talking to your doctor. Stopping Alphadopa L Tablet suddenly may cause serious heart problems such as angina (chest pain) or even a heart attack. If you need to stop taking Alphadopa L Tablet, your doctor will reduce the dose slowly over 1 or 2 weeks.

Will I need to stop taking Alphadopa L Tablet before surgery?

Your doctor may advise you to stop taking Alphadopa L Tablet for 24 hours before surgery. This is because Alphadopa L Tablet can lower your blood pressure too much when its use is combined with some anesthetics. So, tell your doctor that you're taking Alphadopa L Tablet if you're going to be put to sleep using a general anesthetic or are scheduled to have any kind of major operation.

What happens on taking more than the recommended dose of Alphadopa L Tablet?

Taking more than the recommended dose of Alphadopa L Tablet can lead to a drop in blood pressure and slowing of the heart rate, difficulty breathing, or a drop in blood sugar, which can cause sweating or confusion. If you take too many tablets, tell your doctor immediately or contact the hospital emergency department nearest to you.

How long does Alphadopa L Tablet take to work?

If you are taking Alphadopa L Tablet for high blood pressure, it may lower your BP within 1-3 hours of taking it. You may not feel any different, but this does not mean that the medicine is not working, and it is important to keep taking it. On the other hand, if you are taking it for angina, it will probably take a few days for the medicine to reduce the pain. You may still have chest pain during this time or it may get worse.
