How Ziac (bisoprolol / hydrochlorothiazide) works
Ziac (bisoprolol / hydrochlorothiazide) is a combination of two different medications that both help lower blood pressure.
- Bisoprolol is a beta blocker. It works by blocking certain chemicals from attaching to beta receptors on the heart. This slows down your heart rate and lowers your blood pressure.
- Hydrochlorothiazide is a thiazide diuretic (water pill). It works in your kidneys and move extra water and certain electrolytes into your urine. This helps remove extra water from your body. As a result, it helps lower your blood pressure.

Pharmacist tips for Ziac (bisoprolol / hydrochlorothiazide)
- Ziac (bisoprolol / hydrochlorothiazide) can make you urinate more often. Try to take the medication in the morning or early afternoon. This helps you to avoid having to get up and use the restroom at night.
- You might feel dizzy while taking Ziac (bisoprolol / hydrochlorothiazide). It can happen when you first start treatment or after your dose gets raised. You might also feel dizzy when standing up after sitting or lying down, which could lead to falls or fainting. This side effect usually gets better after a few days as your body gets used to the medication. But talk to your prescriber if it happens often.
- Ziac (bisoprolol / hydrochlorothiazide) can sometimes cause dizziness and tiredness. Avoid activities that need your full attention, like driving or using other machinery, until you know how the medication affects you. This helps prevent accidents.
- Be sure to wear a hat and use a sunscreen with an SPF of at least 30 when you go outside, even on overcast and winter days. The diuretic in Ziac (bisoprolol / hydrochlorothiazide) can make your skin more sensitive to the sun and make it easier for you to get sunburns.
- If you have a surgery coming up, tell the surgery team that you're taking Ziac (bisoprolol / hydrochlorothiazide). They'll closely monitor your heart rate to keep you safe.
- Don't stop taking Ziac (bisoprolol / hydrochlorothiazide) suddenly without talking to your prescriber. It can cause your blood pressure to rise to very high levels. It can also raise your risk of serious heart problems like chest pain or heart attack.

Risks and warnings for Ziac (bisoprolol / hydrochlorothiazide)
Ziac (bisoprolol / hydrochlorothiazide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk of heart problems after stopping Ziac (bisoprolol / hydrochlorothiazide) suddenly
- Risk factors: Stopping Ziac (bisoprolol / hydrochlorothiazide) suddenly | Coronary artery disease
Don’t stop taking Ziac (bisoprolol / hydrochlorothiazide) suddenly. It can raise your risk of serious heart problems, like chest pain, heart attack, or irregular heart rhythm. The risk might be higher for people with coronary artery disease (CAD).
Get medical help if you have chest pain, pain that spreads to your shoulder and neck, shortness of breath, dizziness, fatigue, or irregular heartbeat. These can be signs of serious heart problems.
If you need to stop Ziac (bisoprolol / hydrochlorothiazide), talk to your prescriber. They can help lower your dose safely over about a week or two before stopping completely.
Risk of heart failure
- Risk factors: Heart failure
In some cases, beta blockers like the bisoprolol in Ziac can raise the risk of heart failure. This is because beta blockers can affect how the heart beats. If you already have heart failure, your healthcare professional (HCP) will only prescribe Ziac (bisoprolol / hydrochlorothiazide) if they believe the benefits outweigh the risks.
Get medical help right away if you have signs of heart failure. Watch for any trouble breathing, fast or irregular pulse, sudden weight gain, or swelling in your feet or ankles.
Changes in fluids and electrolytes in the body
- Risk factors: Liver problems | Dehydration
Ziac (bisoprolol / hydrochlorothiazide) can cause your body to lose fluids and change your electrolyte levels. If you have liver problems, small changes in fluid and electrolyte levels can raise your risk for liver complications.
Tell your care team if you have dry mouth, weakness, muscle cramps, tiredness, fast or irregular heart rate, nausea, or vomiting. These can be signs of abnormal fluid and electrolyte levels. Your HCP might recommend regular blood tests to check your electrolyte levels while taking Ziac (bisoprolol / hydrochlorothiazide).
Hidden symptoms of low blood sugar
- Risk factors: Diabetes | Fasting (e.g., related to getting surgery, not eating regularly, vomiting)
Beta blockers, like the bisoprolol in Ziac, can make it harder to notice signs of low blood sugar. Some signs, like a fast heartbeat, tremors, hunger, and irritability, might not be as noticeable. Sweating might be the only sign you have warning you of a dangerous drop in your blood sugar levels. This is especially important for people with diabetes to be aware of. Speak with your HCP about when and how to check your blood sugar if you start Ziac (bisoprolol / hydrochlorothiazide).
Hidden symptoms of overactive thyroid
- Risk factors: Hyperthyroidism
If you have hyperthyroidism (overactive thyroid), talk to your HCP before stopping Ziac (bisoprolol / hydrochlorothiazide). The bisoprolol in Ziac can hide signs of hyperthyroidism, like a fast heart rate. Suddenly stopping this medication can worsen symptoms of hyperthyroidism. It can also lead to a serious condition called a "thyroid storm,” which can cause high fever and rapid heartbeat.
Caution use in people with breathing problems
- Risk factors: History of asthma | History of chronic obstructive pulmonary disease (COPD) | History of lung problems
Tell your prescriber if you have any breathing problems, like asthma. Medications with beta blockers, such as Ziac (bisoprolol / hydrochlorothiazide), can worsen breathing problems. This medication has a lower chance of causing breathing problems than other beta blockers because it mainly affects the heart. But you should still be aware of this risk. Keep a rescue inhaler nearby in case you have sudden trouble breathing if you have lung problems.
Caution use in people with peripheral artery disease (PAD)
Let your prescriber know if you have peripheral artery disease (PAD). This medication can cause symptoms of PAD to get worse. Your prescriber can make sure it's safe for you to take. Tell your care team if you notice that your PAD symptoms get worse while taking Ziac (bisoprolol / hydrochlorothiazide).
Risk of vision problems and glaucoma
- Risk factors: History of sulfa or penicillin allergy
Hydrochlorothiazide, one of the ingredients in Ziac, can rarely cause glaucoma and a rise in eye pressure. This can lead to sudden changes in vision or eye pain that can happen within hours to weeks of starting the medication. Stop taking Ziac (bisoprolol / hydrochlorothiazide) and call your eye specialist right away if you notice sudden vision changes or eye pain. If left untreated, it can possibly lead to permanent blindness.
