Felodipine in Australia — What You Need to Know

Felodipine is a calcium channel blocker used to lower high blood pressure and reduce strain on the heart. Doctors prescribe it when lifestyle changes aren’t enough or alongside other blood pressure drugs. It relaxes blood vessels so blood flows easier.

You’ll find felodipine as extended‑release tablets in common doses of 2.5 mg, 5 mg and 10 mg. Brand names include Plendil, and generic versions are widely available. Because it’s extended‑release, most people take felodipine once daily, usually in the morning.

How to buy felodipine safely in Australia

Felodipine is prescription‑only in Australia. You need a valid script from an Australian GP or specialist. Buy from community pharmacies or online Australian pharmacies that are registered and require prescriptions. Look for a physical address, pharmacist contact details, and clear dispensing policies on the site. Avoid sellers that offer felodipine without a prescription or ship from unknown overseas warehouses.

If you consider an online pharmacy, check it is Australian‑registered and shows TGA‑approved brands or generics. Ask your local pharmacist how a specific brand compares to what you were prescribed. Pharmacists can confirm bioequivalence and advise on price differences and possible interactions.

Quick dosing and safety tips

Stick to your prescriber’s dose and take it at the same time each day. Don’t stop felodipine suddenly — blood pressure can rebound. If you miss one dose, take it as soon as you remember unless it’s close to the next dose; don’t double up.

Common side effects include headache, flushing, dizziness and swelling of the ankles. These often ease after a few weeks. Serious signs that need urgent care are fainting, chest pain, a fast or irregular heartbeat, or severe allergic reactions.

Watch for drug interactions. Grapefruit and grapefruit juice boost felodipine levels and can cause extra dizziness or low blood pressure. Strong CYP3A4 inhibitors such as ketoconazole or some macrolide antibiotics may increase drug levels; inducers like rifampicin can reduce effectiveness. Tell your doctor about all medicines, supplements and herbal products you take.

Practical tips for follow up

Measure your blood pressure at home during the first weeks on felodipine and share readings with your doctor. If you have liver disease, heart failure or are pregnant or breastfeeding, discuss risks and alternatives before starting. If cost is a concern, ask your pharmacist about generic options or patient assistance programs.

When felodipine is added to other blood pressure medicines like ACE inhibitors or beta blockers, your blood pressure can drop too low. Your doctor may start a lower dose and schedule a check a week or two after the change. Keep a record of symptoms such as lightheadedness or fainting and bring that to appointments. Store tablets in a cool, dry place and keep them away from children. Never share your medication. Talk to your pharmacist regularly.

If something feels off — more dizziness, swollen legs, or unusual symptoms — call your prescriber or pharmacist. For safe, effective treatment, combine the right prescription, regular monitoring, and honest communication with your healthcare team.
