Why macrolides are the pair people shrug at
Azithromycin and clarithromycin are common 'just five days' scripts. Ciprofloxacin is a common 'just a week' script. Together they sit on the label's QT avoid list.
Staggering breakfast and supper does not unpair them. Both are still in the body. QT risk is not a same-hour-only problem.
If both are already swallowed, call the prescribers before the next dose of either. This desk will not time a homemade washout.
What I would say out loud about the pair list
I would put the names on one line before the first 250: amiodarone, sotalol, other class III, class IA, a macrolide, a tricyclic, an antipsychotic. If two sit together, call before the next dose of either.
Stagger is not unpairing. A GP who said breakfast and supper did not wash out sotalol. If you already feel faint or odd-beating, that is urgent, not a timing tweak.
Known long QT, prior torsade, or syncope on a prior quinolone: ECG talk belongs before the first 250, not after. A healthy 30-year-old on 250 mg alone does not automatically need a tracing this log can order. This desk orders nothing.
Uncorrected low potassium or magnesium is a risk factor to fix, not a homemade antidote you stack on a forbidden pair. Magnesium products can also chelate Cipro if they share the hour.
Elderly susceptibility is labelled. Female sex appears in many QT reviews. The action is still the pair list and the electrolytes, not a stereotype. A 28-year-old on sotalol plus Cipro 250 is still an avoid.
The tendon log still applies on a clean QT list. Myasthenia and neuropathy still apply. Sudden tearing back pain is the aortic sentence and 112. Say ciprofloxacin.
When an ECG is a sentence, not theatre
Known long QT, prior torsade, a class III agent, or syncope on a prior quinolone: ECG talk belongs before the first 250, not after.
A healthy 30-year-old on 250 mg alone does not automatically need a tracing this log can order. This desk orders nothing.
New syncope on Cipro plus azithromycin is emergency care, not a 'get an ECG next week' plan.
Jonas does not read tracings from a phone photo.
Who the interval likes to stretch
The PI notes elderly susceptibility. Many QT reviews also flag female sex as a risk in drug lists. This log will not invent a millisecond chart.
The action is still the pair list and the electrolytes, not a stereotype.
A 28-year-old on sotalol plus Cipro 250 is still an avoid. Age does not save that pair.
Bradycardia and recent infarct sit on the same risk paragraph as the drugs.
After someone holds the pair
Document both names and the hours of the hold. The next infection needs that note.
Unused 250s are a take-back question. They are not a 'finish later with the Z-pack gone' kit without a new plan.
Cash stays 250x14. A hold does not invent a 500 mg dollar.
[email protected] for cites, not for clearance to restart both.
This is not the Levitra QT log
Vardenafil has its own QT language on the ED rack. Do not paste that paragraph onto Cipro or the reverse.
A man on both a PDE5 and a fluoroquinolone needs two cards, not a blended scare. Indications differ. Lists overlap only where the chart says they do.
Related vardenafil notes live on the ED side of this catalogue if that file is up. This log stays antibacterial.
A pair does not change 250x14
Still $16.46 / $14.38 for fourteen 250 mg tablets (16 July 2026). QT fear does not invent a 500 mg dollar.
Unused tablets after a hold are a pharmacy question.
[email protected] is for cite repairs.
- Avoid known long QT and electrolyte holes
- IA / III / tricyclics / macrolides / antipsychotics
- Stagger is not unpairing
- 250 mg still counts
Other QT names people forget
The PI's examples are IA, III, tricyclics, macrolides, antipsychotics. Other QT-active drugs exist (some antiemetics, some methadone stories).
This log will not become a complete CredibleMeds dump. If a drug has a QT warning, put it next to Cipro 250 and ask.
Stagger remains a fail. Both drugs still circulate.
The tendon log still applies on a clean QT list.
Last stamp on the Cipro QT log
Class IA and III, tricyclics, macrolides, antipsychotics. Known long QT, low K or Mg, bradycardia, recent infarct, elderly susceptibility. Put the names on one line before swallow one.
Magnesium is a risk factor to fix, not a homemade shield that shares the hour and chelates the tablet. SSRIs are not automatically invisible. Ask. This desk will not rank them by millisecond.
New syncope on Cipro plus a macrolide is emergency care, not an ECG next week. Bring both bottles. Document a hold with both names and hours.
The tendon log still applies on a clean QT list. Cash stays 250x14. A hold does not invent a 500 mg dollar.
Other QT-active names exist. If a drug has a QT warning, put it next to 250 and ask. Tizanidine is a 1A2 pair that still needs a call.
Dr. Jonas Berg. [email protected] for cites, not for clearance to restart both. Compared 2026, the published pair line stays the PI list. Xalira does not fill.
The list, said as names
Class IA: quinidine, procainamide. Class III: amiodarone, sotalol. Those are the antiarrhythmic examples the PI writes.
Tricyclic antidepressants. Macrolide antibacterials. Antipsychotics as a group in the same sentence.
Congenital long QT. Uncorrected low potassium or low magnesium. Heart failure, recent infarct, bradycardia. Elderly patients more susceptible.
| Pair or factor | Bench stamp | Folk fix that fails |
|---|---|---|
| Cipro + azithromycin | Avoid | Alternate hours |
| Cipro + amiodarone | Avoid | Half the 250 |
| Low K+ | Correct, or pick another class | Banana and hope |
Names people forget that still need a question
The PI's examples are IA, III, tricyclics, macrolides, antipsychotics. Other QT-active drugs exist: some antiemetics, some methadone stories. This log will not become a complete CredibleMeds dump.
If a drug has a QT warning, put it next to Cipro 250 and ask. SSRIs are not the PI's tricyclic example. Some have their own QT language at high dose. Do not assume not a TCA means invisible. This desk will not rank antidepressants by millisecond.
Ondansetron and similar names belong in the ask pile, not in a Helsinki yes. Tizanidine is a 1A2 pair more than a QT pair. It still needs a call.
After someone holds the pair, document both names and the hours. The next infection needs that note. Unused 250s are a take-back question, not a finish later with the Z-pack gone kit.
Cash stays 250x14. A hold does not invent a 500 mg dollar. Splitting 500s is a different NDC.

When the infection is real and the pair is already written
Someone has to own the ECG, the electrolytes, and the organism. That someone is not a static page.
Holding Cipro until azithromycin ends may be the move. Switching Cipro to another class may be the move. Continuing both with monitoring may be a hospital move. Helsinki will not pick from a form.
Tendon risk remains even if the QT pair is cleared. Two logs, one drug.
When an ECG is a sentence, not theatre
Class III already on board, prior torsade, or syncope on a prior quinolone: the tracing conversation belongs before swallow one.
New syncope on Cipro plus a macrolide is emergency care, not a get an ECG next week plan. 112. Bring both bottles.
Jonas does not read tracings from a phone photo. He does not clear you for a second macrolide by mail.
Bradycardia and recent infarct sit on the same risk paragraph as the drugs. A climbing cuff is not this log. A slow pulse plus a pair is.
Electrolyte repletion, when needed, is a clinician act. It is not a reason to keep a forbidden pair because you bought magnesium.
Compared 2026, the published pair line stays the PI list. We will not invent a millisecond chart. We will not invent a 500 mg coupon.
Electrolytes are the quiet pair
Vomiting, diuretics, and a week of poor intake open a potassium hole. Adding Cipro 250 into that hole is a labelled risk pattern.
This bench will not quote a QTc millisecond it did not measure. 'Correct the hole or choose another class' is the usable sentence.
Magnesium belongs in the same caution. Do not invent a milligram of Mg that 'cancels' Cipro.
Publish the pair list without a homemade washout
Sample the other drugs. Assay the PI list. Peer-stamp macrolides as non-optional. Publish.
Compared 2026, dual short courses still sneak through. The list did not get shorter.
Dr. Jonas Berg, Helsinki. Syncope or a racing irregular pulse: 112, not a thread.
