Contents of the pack and other information



Your tablets contain two medicines, lisinopril an ACE (angiotensin converting enzyme) inhibitor and
hydrochlorothiazide a thiazide diuretic, which work together to lower your blood pressure. You have
been given Lisinopril and Hydrochlorothiazide because your high blood pressure was not being
adequately treated using lisinopril or hydrochlorothiazide alone.



Do not take Lisinopril and Hydrochlorothiazide:

if you are allergic to lisinopril, other ACE inhibitors or any of the other ingredients of this
medicine (listed in section 6 )
if you are allergic to hydrochlorothiazide or other sulphonamides (medicines chemically related
to hydrochlorothiazide)
if you have previously been treated with an ACE inhibitor and have suffered an allergic reaction
called angioedema. Symptoms may include swelling of the face, lips, tongue or hands and feet,
or breathing difficulties
if you or one of your family have ever suffered from the allergic reaction called angioedema for
any reason
if you have severe kidney disease or cannot pass urine.
if you are more than 3 months pregnant. (It is also better to avoid Lisinopril and
Hydrochlorothiazide in early pregnancy – see Pregnancy and breast feeding section.)
if you have severe liver disease.
if you have diabetes or impaired kidney function and you are treated with a blood pressure
lowering medicine containing aliskiren.

Ask your doctor if you are not sure.

Warnings and precautions
Talk to your doctor or pharmacist before taking Lisinopril and Hydrochlorothiazide:

if you feel dehydrated due to treatment with diuretics, dialysis, a low salt diet, vomiting or
diarrhoea. You may be more likely to suffer from a large drop in your blood pressure when you
start taking your tablets and may feel faint or light-headed. Your doctor will monitor you closely
at the start of treatment and if your dose is adjusted.

if you think you are (or might become) pregnant. Lisinopril and Hydrochlorothiazide Tablets are
not recommended in early pregnancy, and must not be taken if you are more than 3 months
pregnant, as it may cause serious harm to your baby if used at that stage (see pregnancy section)

if you are at risk of high levels of potassium in your blood eg. from taking potassium-containing
salt substitutes or supplements

if you have heart or blood vessel disease

if you have heart (aortic) valve disease or an enlarged heart

if you have a narrowing (stenosis) of the aorta (an artery in your heart) or mitral valve (a valve
in your heart)

if you are suffering from heart failure and are taking medicines called ACE inhibitors

if you have liver disease or liver problems

if you have kidney problems, need dialysis treatment or have had a kidney transplant

if you suffer from narrowing of the blood vessels to the kidney

if you have diabetes. As you may need a different dose of your antidiabetic medicine (including

if you suffer from gout

if you have a history of allergy, bronchial asthma or SLE (system lupus erythematosus is an
allergic condition causing joint pain, rashes and fever)

if you need blood separation treatment (apheresis) or desensitisation treatment eg. following a
wasp or bee sting; your doctor may wish to interrupt treatment with this medicine to prevent a
possible allergic reaction

if you need to have surgery or a general anaesthetic. Tell the doctor, dentist or hospital staff you
are taking this medicine

if you play competitive sports as hydrochlorothiazide is a banned substance and may give a
positive result in anti-doping tests.

if you are taking any of the following medicines used to treat high blood pressure:
- an angiotensin II receptor blocker (ARBs) (also known as sartans - for example valsartan,
telmisartan, irbesartan), in particular if you have diabetes-related kidney problems.
- aliskiren

if you are taking any of the following medicines, the risk of angioedema (rapid swelling under
the skin in areas such as the throat) is increased:
- sirolimus, everolimus and other medicines belonging to the class of mTOR inhibitors (used to
avoid rejection of transplanted organs)
Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g.
potassium) in your blood at regular intervals.
See also information under the heading “Do not take Lisinopril and Hydrochlorothiazide”
Use in Afro-Caribbean patients: ACE inhibitors may be less effective. You may also more readily get
the side effect ‘angioedema’ (a severe allergic reaction with swelling of the hands, feet, ankles, face,
lips, tongue or throat)
While taking Lisinopril and Hydrochlorothiazide
If you develop any of the following symptoms let your doctor know immediately:

if you feel dizzy after your first dose. A few people react to their first dose or when the dose is
increased by feeling dizzy, weak, faint and sick. Lie down if your blood pressure drops too low.

Complaints such as a dry mouth, thirst, lethargy, muscle pain or cramps, a racing heart,
dizziness, feeling or being sick, and passing less urine, are signs of a fluid or mineral imbalance
in the body.
Page 2 of 8

Sudden swelling of the lips, face, neck, and possibly hands and feet, a rash, difficulty
swallowing or breathing, hoarseness, are signs of angioedema. This may occur at any time
during treatment. There is a higher risk in black patients.

High temperature, sore throat and mouth ulcers, are signs of a low white cell count in the blood
Yellowing of the skin or whites of the eyes, may be a sign of liver problems.

monitor the level of salts in your blood from time to time.

You should not drink alcohol while being treated with this medicine, because in some cases alcohol
can make the side effects worse.

Page 6 of 8

Try to take the tablets at the same time each day. Many patients prefer to take Lisinopril and
Hydrochlorothiazide in the morning so that the effects of the diuretic (passing more water than
usual) occur during the daytime.
If you are taking this medicine for the first time or your dose is increased, you may feel lightheaded or dizzy for a short time and it may help to sit or lie down. This is unlikely to happen
when you are taking the tablets regularly. If you are worried, contact your doctor.

If you take more Lisinopril and Hydrochlorothiazide than you should
Contact your doctor or nearest hospital emergency department immediately. Take this leaflet, the
container and any remaining tablets with you so your doctor will know what you have taken.
Symptoms of overdose may include severe low blood pressure, an unusual amount of salt in the body
and dehydration due to passing a large amount of urine, fast breathing, fast or irregular heart beat,
slow heart beat, dizziness, anxiety, cough and kidney failure.
If you forget to take Lisinopril and Hydrochlorothiazide
Take your normal dose when it is next due. Do not take a double dose to make up for a forgotten dose.
If you stop taking Lisinopril and Hydrochlorothiazide
Do not suddenly stop taking this medicine as this may cause serious changes in your blood pressure.
If you want to stop the treatment discuss this with your doctor or pharmacist.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
