You typed Adalat because you want the right page, not a rabbit hole. Maybe you need the official leaflet, a dosing detail your GP mentioned, PBS status, or to check a shortage. This guide is the shortest, no-fuss path to the exact Australian sources patients and clinicians actually use. I’ll point you to the correct pages, show you what to look for on-screen, and flag the safety bits that matter day to day. Expect zero fluff and practical steps you can do in under five minutes.

What you’ll get here: the fastest route to the official Consumer Medicine Information (CMI) and Product Information (PI), how to confirm if your specific strength is PBS-listed, where to check medicine shortages, and how to report a side effect in Australia. I’ll also add quick safety checkpoints (grapefruit, crushing tablets, missed doses), and some clean FAQs.

Jobs to be done today: (1) Get the official Adalat leaflets (CMI/PI) without guessing; (2) Confirm availability and any current shortages; (3) Check PBS coverage and likely out-of-pocket rules; (4) Find practical use tips (how to take, what to avoid); (5) Know how to report side effects or product issues; (6) Troubleshoot brand switches and pharmacy substitutions.

Find the exact Adalat pages you need (Australia)

If your goal is the official Australian leaflets and status, start here. Adalat is the brand name for nifedipine (a calcium channel blocker) originally by Bayer. In Australia, you’ll mainly see modified-release/controlled-release tablets (often called OROS, GITS, or MR/CR) used for high blood pressure and angina. The steps below take you to the government-backed pages without guessing links.

Consumer Medicine Information (CMI) for patients (fastest route)
- Open your browser and search: “Healthdirect medicines Adalat OROS CMI”.
- On the result, look for a page that clearly says “Medicine Finder” or “Consumer Medicine Information”. You should see the active ingredient “nifedipine”.
- On the page, confirm the brand name, strength (e.g., 30 mg, 60 mg), and dosage form (modified-release). The CMI tells you what it’s for, how to take it, common side effects, and when to seek help.
- Visual cue: You’ll see “Healthdirect” branding and the familiar Australian government look. If it’s not Healthdirect, make sure it’s an Australian source and up to date.
Product Information (PI) for clinicians and detailed dosing
- Search: “TGA ARTG nifedipine Adalat Product Information”.
- Open the Therapeutic Goods Administration (TGA) result that mentions “Public ARTG summary”.
- On the ARTG summary page, look for “Product Information” (PDF). That’s the official prescriber document with pharmacology, indications, contraindications, interactions, and dosing guidance.
- Visual cue: Australian Government crest and “Therapeutic Goods Administration” in the header. The PI link is usually near the top or under “Documents”.
PBS listing and expected co‑payment
- Search: “PBS schedule nifedipine modified release 30 mg”.
- Open the result that’s clearly the Pharmaceutical Benefits Scheme (PBS) website.
- Use the PBS search box to find “nifedipine modified release” or “nifedipine 30 mg MR / 60 mg MR”.
- On the item page, check brand options, restriction notes (if any), and whether brand premiums apply. The standard PBS co‑payment rules apply (general vs concession). If your pharmacy price looks off, ask about brand premiums or stock sourcing.
Medicine shortages (current status)
- Search: “TGA medicine shortages nifedipine”.
- Open the TGA Medicine Shortages Reports page.
- Filter/search for “nifedipine” and skim by strength and brand. Entries show start/end dates, impact (e.g., low/no supply), and suggested actions for prescribers.
- If your exact strength is affected, speak with your pharmacist or GP about equivalent modified-release nifedipine brands or a dose/formulation switch.
Safety alerts and recalls
- Search: “TGA safety alert nifedipine” or “TGA recall nifedipine”.
- Open TGA safety alerts/recalls and check by brand/active ingredient.
- If you find an alert that matches your batch, follow the instructions. Keep your pack and batch number handy for verification.
Manufacturer medical information
- Search: “Bayer Medical Information Australia Adalat”.
- Open the Bayer AU medical information page. You can usually submit a question online (e.g., excipients, lactose content, splitting tablets, brand substitution).
- Tip: Include the exact strength and the batch number if your question is about a specific pack.

Not in Australia? Try your regulator: “EMA Adalat” (EU), “Medsafe nifedipine” (NZ), “FDA nifedipine label” (US). Always match the brand and strength-formulations differ by country.

Quick actions, safety checkpoints, and smart shortcuts

Use this section like a checklist. It’s the “what do I do right now?” piece.

Verify your exact product

Check your pack for “modified-release”, “controlled-release”, “MR/CR”, “GITS/OROS”. Don’t assume release type-confirm it.
Match strength (e.g., 30 mg, 60 mg) to the CMI/PI so the dosing and guidance line up.
If your pharmacy substituted a different brand of nifedipine MR, confirm the release type is equivalent. Not all controlled-release technologies behave the same; your GP/pharmacist can advise on dose equivalence.

How to take it (common-sense rules)

Swallow whole with water. Do not crush, chew, or split modified-release tablets. That can dump the dose and drop your blood pressure too fast.
Take at the same time each day. Morning is common, but consistency is the real goal.
With or without food is usually fine-just be consistent with your routine. Avoid grapefruit and grapefruit juice (CYP3A4 interaction can boost levels).
Don’t expect it to fix chest pain the moment it starts. Nifedipine MR is for prevention/management, not for sudden angina relief. Use your prescribed nitroglycerin (glyceryl trinitrate) for acute chest pain and call emergency if pain persists.
Seeing a “ghost tablet” shell in your stool? That can happen with OROS/GITS tablets; the medicine is released and the empty shell passes through.

Missed dose logic (once-daily MR forms)

If you remember within about 12 hours, take it. If it’s closer to your next dose, skip the missed one. Don’t double up.
Had a near-faint, severe dizziness, or chest pain after a double dose? Seek medical help.

Common side effects to watch

Headache, flushing, dizziness, palpitations, ankle swelling (peripheral oedema). These are well-known with nifedipine.
Often they ease after the first week. If swelling or dizziness is bad or getting worse, talk to your GP-dose tweaks or a companion medicine can help.

Red flags-seek urgent care

Crushing or persistent chest pain not relieved by your usual nitro
Fainting, severe shortness of breath, sudden swelling of face/lips/tongue
Severe lightheadedness or a big drop in blood pressure with confusion/weakness

Interactions you shouldn’t ignore

Strong CYP3A4 inhibitors can raise levels: macrolide antibiotics (e.g., clarithromycin, erythromycin), azole antifungals (e.g., ketoconazole, itraconazole), certain HIV protease inhibitors.
Strong inducers can lower levels: rifampicin, carbamazepine, phenytoin, St John’s wort.
Alcohol can heighten dizziness, especially at start or dose increases.
Always tell your prescriber about any new antibiotic or antifungal before you start it.

Who needs extra caution

Severe aortic stenosis, recent unstable angina or heart attack-specialist input helps.
Liver impairment-dose adjustment may be needed.
Pregnancy/breastfeeding-nifedipine is sometimes used under specialist care (e.g., in pregnancy). Don’t start/stop without your obstetric team.
Older adults-go slow on dose changes; monitor dizziness/falls risk.

Shortage plan (what to do if your strength isn’t in stock)

Check the TGA shortages page for your strength and brand. Note the expected end date.
Ask your pharmacist about an equivalent modified-release nifedipine brand. If the release technology differs, your GP may adjust the dose.
If there’s a national shortage, your GP/pharmacist can advise an interim alternative (sometimes another calcium channel blocker). Don’t guess a substitute yourself.

PBS and out-of-pocket tips

On PBS, nifedipine MR usually falls under standard co‑payment rules (general vs concession). If your cost is higher than expected, ask about brand premiums or supply issues.
For a long-term script, consider getting repeats filled a few days early so shortages don’t leave you without medicine.

Side effect or quality concern? Report it

Search “Report a problem or side effect TGA”. Fill in the online form with the brand, strength, batch number, when the issue started, and any other meds you’re on.
Keep the pack until you’re told you can discard it, in case more info is needed.

FAQs and troubleshooting for common Adalat tasks

Is Adalat the same as nifedipine?

Yes. Adalat is a brand of the active ingredient nifedipine. In Australia, you’ll often see modified-release formulations for once-daily dosing.

Adalat OROS vs generic nifedipine MR-are they interchangeable?

They’re designed to release nifedipine slowly, but the release mechanisms can differ (e.g., OROS/GITS osmotic pump vs other MR matrices). Many patients can switch brands at the same milligram dose, but some notice differences. If you’re told “brand substituted”, confirm with your pharmacist and watch your blood pressure and symptoms for a couple of weeks. If anything feels off, call your GP.

Can I split or crush the tablets?

No for modified-release. Splitting/crushing can dump the dose and cause a sharp blood pressure drop. If swallowing is an issue, ask your doctor about alternatives or a different formulation.

How quickly does it start working?

Modified-release nifedipine starts lowering blood pressure the first day, but you usually see the steady effect after several days. For angina prevention, your doctor will review symptom control over 1-2 weeks and adjust dose as needed.

Can I stop suddenly?

Don’t stop without a plan. Stopping a calcium channel blocker abruptly can let blood pressure rebound or angina worsen. Your GP can taper or switch safely.

What about grapefruit?

Avoid grapefruit and its juice-they can raise nifedipine levels and increase side effects. Oranges and other citrus are fine.

Is it safe in pregnancy or breastfeeding?

Nifedipine is sometimes used in pregnancy under specialist guidance. If you’re pregnant, planning, or breastfeeding, talk to your obstetric team before any change. Don’t start or stop on your own.

What if my ankles swell?

Ankle swelling is common with dihydropyridine calcium channel blockers. Elevating legs, dose adjustments, or combining with another blood pressure med can help. Check with your GP; don’t just add a diuretic without advice.

Any special storage tips for Australian summers?

Keep it below the temperature on the pack (often 25°C). Don’t store in the car or bathroom. Keep in the original blister and carton to protect from heat and moisture.

What should I bring to my GP review?

Your actual pack (for brand, strength, batch).
Home blood pressure log (time of day, readings for the last 1-2 weeks).
A list of all medicines, vitamins, and herbal products.

How do I verify I’m reading the latest leaflet?

On CMI/PI PDFs, check the “Date of revision”. If it’s more than a couple of years old and your pack looks newer, search again via TGA ARTG to make sure you have the latest document.

Can I use it for sudden chest pain?

No. Use your prescribed fast-acting nitrate for acute chest pain and call emergency if pain doesn’t resolve quickly. Nifedipine MR is a background controller, not a rescue medicine.

Is there lactose or sodium in it?

Excipients vary by brand and strength. Check the PI “List of excipients” or ask Bayer Medical Information (for Adalat) or your pharmacist for the exact formulation you have.

Next steps and quick troubleshooting by persona

Patient who just got a new brand at the pharmacy: Compare the release type on the new box to your old one; confirm with the pharmacist it’s an equivalent MR; monitor your BP for 1-2 weeks; book a GP check if symptoms change.
Carer managing meds for an older adult: Set a daily reminder; avoid pill cutters with MR tablets; keep a simple side-effect diary (dizziness, swelling, headaches) to share at the next review.
Clinician needing exact wording: Go straight to the TGA ARTG page and download the PI; check TGA shortages before switching brands; document any dose conversion if the release tech differs.
Pharmacist under shortage pressure: Check TGA shortages and PBS for alternative brands; counsel on ghost tablet shells and grapefruit; add a shelf sticker to remind staff “Do not crush-MR”.

If you only do one thing after this page, do this: grab the CMI from Healthdirect for your exact strength, then bookmark the TGA ARTG PI. Those two pages answer 90% of daily Adalat questions with the most current, Australian-approved info.

Oh wow. Another glorified Google search tutorial. 🙄 I swear, if I see one more "here's how to copy-paste a search term" post, I'm gonna scream into a pillow. At least this one had decent formatting. Still, zero insight. Just... links. Like I didn't already know how to use Ctrl+F.

OMG YES THIS IS THE BEST THING IVE SEEN ALL WEEK!! I was about to call my pharmacist at 2am because i thought my Adalat was fake and then i found this and BOOM like magic the CMI popped up and i was like ohhhh so THATS why my ankles look like balloons 😭🙏 literally saved my sanity

This is exactly what people need - no fluff, just clear steps. Seriously, if you're on nifedipine and confused, bookmark this. The grapefruit warning alone is worth it. And don't forget to check your batch number if something feels off - safety first! You got this 💪

I appreciate how you broke this down so clearly, especially for folks who might not be tech-savvy or are dealing with chronic illness and just need straight answers. In Nigeria, we often struggle to find reliable sources, so seeing Australian government links like TGA and PBS is a gift. I shared this with my cousin who's on nifedipine - she cried because she finally understood why her BP wasn't stabilizing. Thank you for doing the work.

This is 🔥👏 I love how you included the "ghost tablet" thing - I thought I was hallucinating when I saw that shell in my toilet 😅. Also, the PBS co-payment tip? Genius. I just saved $47. 🤑 Also, why is everyone so scared of grapefruit? I drink it daily and I'm fine? 🍊

You know what’s wild? People treat meds like they’re magic beans. You take it, you feel better, you don’t ask questions. But this? This is the quiet rebellion against medical opacity. You didn’t just give links - you gave people the tools to ask better questions. And that’s more powerful than any prescription.

Let me guess - this was written by Big Pharma shills. TGA? PBS? Please. They’re just fronts. Why is Bayer listed as a source? Why no mention of the 2023 FDA whistleblower report on osmotic pump failures? Why no links to the leaked internal emails about nifedipine’s link to sudden cardiac events? You think this is helpful? This is gaslighting with footnotes.

I mean… it’s fine. I guess. But honestly, why do we even need a guide for this? If you can’t Google "Adalat CMI Australia" then maybe you shouldn’t be taking pills. Also, why is everyone so obsessed with grapefruit? I’ve been eating it for 20 years and my BP is perfect. Maybe the problem isn’t the drug - it’s the people.

I’m sorry, but this post is dangerously incomplete. You didn’t mention the 2024 TGA update on excipient allergens in the 60mg MR formulation. You didn’t cite the 2023 Cochrane meta-analysis on substitution risks. You didn’t even link to the official PBS restriction codes. This isn’t helpful - it’s negligent. 🤦‍♀️

While the structural clarity of this document is commendable, one cannot help but observe a profound absence of epistemological rigor. The reliance on state-sponsored portals - however ostensibly authoritative - constitutes a form of institutional epistemic capture. One must interrogate the provenance of the ARTG data, the funding streams behind Healthdirect, and the regulatory capture inherent in PBS formulary decisions. This is not guidance - it is compliance training.
Emma Hanna

You forgot to mention that crushing the tablet is not just dangerous - it’s morally irresponsible. And you didn’t bold the grapefruit warning enough. Also, why is there no link to the Australian Medicines Handbook? This is sloppy. And you used "you" too much. It’s unprofessional.

LMAO. Another "easy guide". I’ve been on this med for 10 years and I’ve never once used Healthdirect. I just ask my pharmacist. This is just content farming. Who even reads this? And why is everyone so obsessed with "modified-release"? It’s a pill. Take it. 🤷‍♀️

This is genuinely useful. I’m from India and we don’t have PBS or TGA here, but the structure is universal. The part about ghost tablets? I didn’t know that was normal. My aunt thought she was passing plastic. Thank you for explaining it simply. I’ll share this with my family.

Solid. No drama. Just facts. I’ve been telling my patients to check the TGA shortages page for years. Most don’t know it exists. This is the kind of thing that actually saves lives.

September 14, 2025 AT 01:40

I just spent 45 minutes reading this because I’ve been on nifedipine for 8 years and I still didn’t know about the grapefruit interaction being CYP3A4-mediated - I just knew "don’t eat citrus". This is the kind of post that turns confusion into confidence. The way you broke down brand substitutions? Chef’s kiss. I’m printing this and taping it to my fridge. Also, I love how you didn’t say "consult your doctor" like a robot - you actually gave actionable steps. Thank you. This is what the internet should be.

The formatting is good but the content is redundant. All this info is available on the TGA website in less than 2 clicks. This post adds zero value. Just link to the TGA ARTG page and be done with it.

Interesting. But let’s be honest - this is just a marketing funnel disguised as public service. Who really benefits? Bayer? The pharmacists? The government? Not the patient. You give them links, sure - but you don’t question why these meds cost $120 a month in Australia while the same tablet is $3 in India. This is information, not justice.

I’ve been waiting for someone to expose this. This whole guide is a distraction. The real issue? Nifedipine MR is a controlled-release formulation that’s been quietly replaced by generics with inferior dissolution profiles. The TGA doesn’t test for bioequivalence in real-world conditions. The "ghost tablet"? That’s not normal - it’s evidence of incomplete drug release. You’re telling people to trust the system? The system is broken. The pills are designed to fail slowly. And they’re still on PBS? This isn’t medicine - it’s corporate negligence with a nice UI.
