Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with similar-sounding drug names like 'levetiracetam' or 'lamotrigine', which are for different conditions.
- The '-ol' ending is common in drug names (e.g., atenolol, metoprolol) and does not imply it is an alcohol.
Common Mistakes
- Misspelling: 'labetolol', 'labatolol', 'labetallol'.
- Mispronunciation: placing stress on the first syllable (LA-betalol) instead of the second (la-BEET-alol).
- Using it as a countable noun incorrectly (e.g., 'a labetalol') instead of an uncountable/mass noun (e.g., 'a dose of labetalol').

FAQ
Frequently Asked Questions
It is primarily used to treat high blood pressure (hypertension). It is also used in hospital settings for hypertensive emergencies and to control blood pressure during surgery.
It is generally not advised, as alcohol can increase the blood-pressure-lowering effects of labetalol and may cause dizziness or fainting. You should consult your doctor or pharmacist.
It is not typically a first-line treatment for routine hypertension. It is often reserved for specific situations, such as in pregnancy (where it is considered safe) or when other beta blockers are not suitable due to its additional alpha-blocking effect.
Because it can be given intravenously for rapid, titratable control of blood pressure and heart rate, helping to prevent dangerous spikes during procedures like intubation or surgery.
