This prescription item requires a pre approved authority from the Government in order to get this item at the quoted price. Authority prescriptions need to be applied for by the doctor writing the script and can include reasons such as increased quantities due to dosage, increased repeats, use for a pre determined specified use, or the nature of the medication itself requiring specialist interaction. In the event that an authority is not granted on the script, the price will revert to the private price quoted for that item


This item contains more than one pack of a prescription product. Before this can be dispensed the doctor has to give approval. The prescription must be written for the total quantity or the prescription must be endorsed by your doctor "Regulation 24" otherwise we will be unable to dispense the increased amount. If you proceed with the order without approval, we will only send out one pack at the single pack price and refund the difference. Eg If your prescription is written out for 30 Tablets with 5 repeats and it does not have “Regulation 24 “ written on the script, the ONLY quantity we can dispense is 30 at one time. Further dispensing of this product could only occur after an appropriate length of time - usually 21 days but depends on dosage. In this example if you would like to obtain 180 Tablets then the doctor must endorse the prescription “Regulation 24” or the quantity must be written out for 180 and not 30. NB Conditions apply on the writing of a Regulation 24 prescription. Ask your doctor or pharmacist for details.

We can no longer accept signed authority forms from your doctor as permission to dispense more than one pack. Please contact our pharmacist for more information.

If you order this item as Private, NO PBS stickers will be issued. Once any prescription order has been sent the product cannot be returned for a refund even if your doctor changes your medication or you have an adverse reaction.

Consumer Medicine Information

What is in this leaflet
This leaflet answers some common questions about Hydopa.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking Hydopa against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, talk to your doctor or pharmacist.

Keep this leaflet with your medicine.

You may need to read it again.

What Hydopa is used for
Hydopa is used to lower high blood pressure, also called hypertension.

Hydopa works by widening 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 Hydopa has been prescribed for you. Your doctor may have prescribed Hydopa for another reason.

There is no evidence that Hydopa is addictive.

Hydopa is available only with a doctor's prescription.

Before you take Hydopa
When you must not take it
Do not take Hydopa if you are allergic to:

medicines containing methyldopa (e.g. Aldomet)
any of the ingredients listed at the end of this leaflet.
Do not take Hydopa if you:

currently have liver disease (e.g. hepatitis or cirrhosis)
have a past history of liver problems due to taking methyldopa.
Do not take Hydopa if you are taking a medicine called a monoamine oxidase inhibitor (MAOI). MAOIs are used to treat depression and Parkinson's disease. Some examples of MAOIs include phenelzine, tranylcypromine and selegiline.

Ask your doctor or pharmacist if you are not sure whether you are taking one of these MAOI medicines.

Do not take Hydopa if the expiry date (Exp.) printed on the pack has passed. If you take this medicine after the expiry date, it may not work as well.

Do not take Hydopa if the packaging shows signs of tampering or the tablets do not look quite right.

Before you start to take it
Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives.

Tell your doctor if you have, or have had, any medical conditions, especially the following:

liver problems
angina (chest pain).
Tell your doctor if you have or are suspected of having phaeochromocytoma (a rare tumour of the adrenal gland).

Tell your doctor if you are undergoing dialysis (a procedure used to remove waste products from the blood of a person with kidney failure).

Tell your doctor if you are pregnant or plan to become pregnant. Your doctor will discuss the risks and benefits of taking Hydopa during pregnancy.

Tell your doctor if you are breastfeeding or wish to breastfeed. Hydopa passes into breast milk. Your doctor will discuss the risks and benefits of taking Hydopa when breastfeeding.

Your doctor may want to take special care if you have any of these conditions.

If you have not told your doctor about any of the above, tell them before you start taking Hydopa.

Taking other medicines
Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines may be affected by Hydopa, or may affect how well it works. These include:

other medicines used to treat high blood pressure
monoamine oxidase inhibitors (MAOIs), medicines used to treat depression and Parkinson's disease.
Do not take Hydopa if you are taking a MAOI.

lithium, a medicine used to treat mood swings and some types of depression
iron supplements and multivitamins containing iron.
Your doctor can tell you what to do if you are taking any of these medicines.

If you are not sure whether you are taking any of these medicines, check with your doctor or pharmacist. Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Hydopa.

How to take Hydopa
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist.

How much to take
The dose varies from person to person.

Your doctor will tell you how many tablets you need to take each day and when to take them.

The usual starting dose for adults is 250 mg, taken two or three times a day. Your doctor may increase or decrease this dose, depending on how you respond to this medicine.

Elderly people over 65 years of age may need smaller doses.

The starting dose for children is based on their weight. Your child's doctor may increase or decrease this dose, depending on their response to Hydopa.

How to take Hydopa
Swallow the tablets with a glass of water.

When to take Hydopa
Take your medicine at about the same time each day, spaced evenly apart. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

Hydopa can be taken with or without food.

How long to take Hydopa for
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 Hydopa
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 take too much Hydopa (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Hydopa. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much Hydopa, you may feel dizzy, lightheaded, drowsy or weak. You may experience nausea (feeling sick), vomiting, constipation, diarrhoea, gas/wind in the bowel or develop a bloated stomach.

While you are taking Hydopa
Things you must do
Before starting any new medicine, tell your doctor or pharmacist that you are taking Hydopa.

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Hydopa.

If you become pregnant while taking Hydopa, tell your doctor.

If you need to have surgery that requires a general anaesthetic, tell your doctor or dentist that you are taking Hydopa.‑

If you need to have any blood or urine tests, tell your doctor that you are taking Hydopa. Hydopa may interfere with the results of some blood and urine tests.

If you develop a fever, tell your doctor. Your doctor may ask you to have blood tests to make sure that Hydopa is not affecting your liver or blood.

If you going to have a blood transfusion, tell your doctor you are taking Hydopa or have taken it in the past few months. Hydopa may interfere with the tests used to decide which blood group you receive.

Since Hydopa is meant to be taken regularly, keep a continuous supply of medicine so you don't run out, especially over weekends or on holidays.

Visit your doctor regularly so they can check on your progress. Your doctor may want to check your liver function and blood count, especially within the first 12 weeks of starting Hydopa.

Things you must not do
Do not stop taking Hydopa, even if you feel better, unless advised by your doctor.

Do not use Hydopa to treat any other conditions unless your doctor tells you to.

Do not give Hydopa to anyone else, even if they have the same condition as you.

Things to be careful of
Be careful driving or operating machinery until you know how Hydopa affects you. Hydopa may cause drowsiness, dizziness or lightheadedness in some people, especially after the first few doses, or if the dose is increased. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

Be careful drinking alcohol while taking Hydopa. Combining alcohol with Hydopa can make you more drowsy, dizzy or lightheaded.

Be careful getting up from a sitting or lying position. Dizziness, lightheadedness or fainting may occur when you begin to take Hydopa, or if the dose is increased. This happens especially when you get up quickly from a sitting or lying position. Getting up slowly may help. This problem usually goes away after the first few days.

Side effects
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Hydopa. Hydopa helps most people with high blood pressure, but it may have unwanted side effects in some people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

If you are over 65 years of age, you may have an increased chance of getting side effects, especially drowsiness and dizziness.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

dizziness, lightheadedness
The above list includes the common and mild side effects of Hydopa, which may disappear with continued treatment. These side effects may occur at the beginning of treatment or when the dose is increased.

Tell your doctor immediately or go to Accident and Emergency at the nearest hospital if you notice any of the following:

ongoing weakness
fever shortly after starting Hydopa, for example, within the first 3 months
yellowing of the eyes or skin (jaundice)
darker urine than normal
pale stools
swelling of the feet or ankles
nightmares, feeling strange or depressed
signs of infection such as fever, chills, sore throat or mouth ulcers
bleeding or bruising more easily than normal
tiredness, looking pale together with being short of breath when exercising and tingling or numbness of the hands or feet
itchy skin rash or other skin problems
slow heart beat or pulse
worsening of angina (chest pain).
These are all serious side effects. You may need urgent medical care. Serious side effects are rare.

Tell your doctor if you notice anything that is making you feel unwell. Other side effects not listed above may also occur in some patients. Some of these side effects (e.g. changes in liver function) can only be found when your doctor does tests from time to time to check your progress.

After taking Hydopa
Keep Hydopa where children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Keep your tablets in the pack until it is time to take them. If you take the tablets out of the pack they will not keep well.

Keep your tablets in a cool dry place where the temperature stays below 30°C.

Do not store Hydopa or any other medicine in the bathroom or near a sink.

Do not leave Hydopa in the car or on window sills. Heat and dampness can destroy some medicines.

If your doctor tells you to stop taking Hydopa, or your tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.
