What Hydopa is used for

Hydopa is used to lower high blood pressure, also called hypertension.
Everyone had blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
There are usually no symptoms of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but eventually hypertension can cause stroke, heart disease and kidney failure. Hydopa helps to lower your blood pressure.
Hydopa works by controlling impulses along certain nerve pathways and as a result, widens blood vessels so that blood passes through them more easily. This helps to lower blood pressure.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
There is no evidence that Hydopa is addictive.
Hydopa is available only with a doctor's prescription.

How to take Hydopa

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.

How much to take

The dose varies from person to person.
This depends on your condition and whether you are taking any other medicines.
Your doctor will tell you how many tablets you need to take each day and when to take them.

How to take it

Swallow the tablets whole with a glass of water.

When to take it

Take your medicine at about the same time each day, unless your doctor tells you otherwise.
If you are taking it twice a day, take the tablets at breakfast time and dinner time - that is about 12 hours apart.
If you are taking it three times a day, take the tablets about 8 hours apart.
Taking it at the same time each day will have the best effect on your blood pressure. It will also help you remember when to take it.
Hydopa can be taken with or without food.

How long to take it

Keep taking Hydopa for as long as your doctor recommends.
Hydopa helps control high blood pressure but does not cure it. To properly control your condition, Hydopa must be taken every day on a long-term basis.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)
