Disclaimer: This information is intended for Australians considering Diltahexal from our online pharmacy. It is not a substitute for professional medical advice. Always talk to your doctor or pharmacist about your treatment and follow the official product leaflet for your medicine.

What is Diltahexal?

Diltahexal is a brand name used for medicines that contain the active ingredient diltiazem. Diltiazem is a calcium channel blocker that helps relax the muscles of the heart and blood vessels. In Australia, the availability of Diltahexal may depend on local rules and the prescriber’s assessment.

This medicine is used to treat certain heart conditions and high blood pressure. The exact formulation, strength and dosing form (for example, immediate-release or extended-release tablets) should be chosen by your clinician based on your condition and how your body responds to treatment.

Diltahexal works by reducing the heart’s workload and dilating (relaxing) blood vessels. This can lead to lower blood pressure and can help prevent chest pain in people with angina. It may also help control heart rate in some rhythm disorders, but this depends on your specific health needs.

This information is general in nature. It does not cover every possible use, interaction or side effect. If you have questions about whether Diltahexal is right for you, talk to your doctor or pharmacist and refer to the official product leaflet that comes with your medicine.

Uses

Diltahexal is prescribed to help manage high blood pressure (hypertension). Lowering blood pressure reduces the risk of complications such as stroke or heart attack in the long term.

It is also used in some people to treat angina. By helping to relax blood vessels, it can improve blood flow to the heart and reduce chest pain associated with restricted blood supply.

In certain heart rhythm disorders, diltiazem may be added to a broader treatment plan to help regulate the heart rate. The decision to use Diltahexal for rhythm control is made by a clinician based on individual heart function and symptoms.

Diltahexal may be prescribed as part of a broader strategy that includes lifestyle changes, other medications and monitoring. Do not adjust other medicines without medical advice, even if you feel your symptoms improve.

How it works

Diltiazem blocks calcium entry into the smooth muscle and heart muscle cells. This leads to relaxation of the blood vessels and a gentle slow-down of the heart rate in some patients.

By dilating arteries and reducing the workload on the heart, diltiazem helps lower blood pressure and can improve blood flow to the heart muscle. This can reduce the frequency and intensity of chest pain in angina for some people.

The effect on heart rhythm depends on the specific heart condition being treated. In rhythm disorders, diltiazem may help prevent excessively fast heart rates by slowing electrical conduction through the atrioventricular node.

As with all medicines, Diltahexal works best when used as prescribed and monitored by a health professional. It is not a cure, but a treatment that can help manage symptoms and reduce cardiovascular risk when combined with other appropriate therapies and healthy lifestyle choices.

How to use

Take Diltahexal exactly as prescribed by your doctor. The dosing schedule is tailored to your health needs and may change over time. Do not alter the amount, timing or form of the medicine without professional advice.

Swallow tablets with a full glass of water. Do not crush or chew extended-release forms unless your clinician specifically instructs you to do so. Extended-release tablets should be taken whole to ensure a steady release of the medicine.

If you miss a dose, take it as soon as you remember unless it is near the time for your next dose. If it is almost time for the next dose, skip the missed dose and return to your normal schedule. Do not double up to make up for a missed dose.

Do not stop taking Diltahexal suddenly without talking to your doctor. Stopping abruptly can cause a sudden change in heart rate or blood pressure and may worsen symptoms.

Tell your doctor about all medicines you take, including over-the-counter medicines, vitamins and supplements. Some medicines interact with diltiazem and can affect how well either medicine works or increase the risk of side effects.

Who should avoid

People who are allergic to diltiazem or other calcium channel blockers should not take Diltahexal. If you have had a serious allergic reaction to this medicine in the past, avoid using it without first discussing with your clinician.

Certain heart conditions may make Diltahexal unsuitable. These include significant bradycardia (very slow heart rate), certain types of heart block, or decompensated heart failure. A clinician will assess these risks before prescribing.

Very low blood pressure or certain severe liver problems may also be a reason to avoid or adjust treatment. Always discuss any liver or kidney issues with your doctor, as you may require monitoring or dosage adjustments.

Diltahexal may not be suitable during pregnancy or while breastfeeding unless a clinician has weighed the potential benefits and risks. Please discuss pregnancy plans or breastfeeding with your healthcare provider before starting therapy.

Warnings

Share a complete list of all medicines you use with your doctor or pharmacist. Some drugs can interact with Diltahexal and may require dose adjustments or monitoring.

Grapefruit and grapefruit juice can interact with several calcium channel blockers. Tell your clinician if you use or plan to consume grapefruit products while taking Diltahexal, as this may require advice or monitoring.

Alcohol can lower blood pressure and may enhance dizziness or light-headedness when you take this medication. Take care when driving or operating machinery until you know how Diltahexal affects you.

If you notice dizziness, fainting, unusually slow heart rate, or swelling in your ankles or feet, contact your clinician promptly. In severe cases, seek urgent medical help.

Side-effects

Most people tolerate Diltahexal well, but some may experience side effects. Common effects include dizziness, headache, flushing, or feeling tired. These are usually temporary and may lessen with time.

Swelling of the ankles or feet, nausea, and constipation can also occur in some patients. If swelling is persistent or bothersome, tell your doctor or pharmacist.

Less common effects can include a slow heart rate, low blood pressure, or mood changes. If you notice chest pain, severe shortness of breath, or signs of an allergic reaction (such as rash, swelling of the face or lips), seek medical help promptly.

This list is not complete. If you experience any other symptoms that concern you, contact your healthcare professional. Do not ignore symptoms that are persistent or worsening.

Interactions

Diltahexal can interact with other medicines. Some interactions can change how well either medicine works or increase the risk of side effects. It is important to tell your doctor about all medicines you currently take, including non-prescription medicines, vitamins and herbal supplements.

Medications that affect heart rate or blood pressure, such as other calcium channel blockers or beta-blockers, may require closer monitoring. Some antiarrhythmic medicines, certain antibiotics or antifungals, and medicines used to treat high blood pressure can interact with diltiazem.

Grapefruit products may interact with diltiazem; discuss with your clinician whether you should limit or avoid grapefruit while using this medicine. Alcohol and certain sedatives may also interact and increase dizziness or drowsiness.

If you are scheduled for surgery or dental procedures, tell the clinician you are taking Diltahexal. They may need to adjust your treatment plan temporarily to avoid adverse interactions.

Pregnancy

Safety in pregnancy has not been established for all situations. The decision to use Diltahexal during pregnancy should be made after careful discussion between you and your clinician, considering the benefits to you and any potential risks to the baby.

Breastfeeding while taking Diltahexal is not routinely recommended unless advised by a healthcare professional. Diltiazem may pass into breast milk and could affect a nursing baby. Discuss with your doctor if you are breastfeeding or planning to breastfeed.

If you become pregnant while taking Diltahexal, contact your clinician promptly. Do not stop the medication without medical guidance, as stopping suddenly can have consequences for your condition.

Always rely on your healthcare professional’s advice for pregnancy-related questions about this medicine. The information provided here is general and not a substitute for individual medical guidance.
