Medication Instructions in Spanish: False Friends and Wording Pitfalls

Directed and reviewed by a family medicine physician & certified medical interpreter

Medication errors often come from small wording differences. A word that looks right in English can mean something else in Spanish, and a frequency that sounds clear can be read two ways.

Real medication teaching for a patient with limited English proficiency should go through a qualified medical interpreter. This guide helps you recognize risky wording, double-check what you hear, and ask better questions. It is not a script for teaching medications yourself. Follow your facility's policy and always use the prescriber's order as the source of the dose, route and timing.

False friends that cause trouble

The Spanish below is neutral Latin American usage.

English word Spanish look-alike What it really means Use instead
drug (medicine) droga Usually an illegal drug medicamento, medicina
preservatives preservativos Condoms conservantes (conservadores in Mexico)
embarrassed embarazada Pregnant avergonzado/a
intoxicated intoxicado/a Poisoned ebrio/a (drunk)
constipated constipado/a In some places, having a cold estreñido/a
actual / actually actual, actualmente Current, currently real (actual), en realidad (actually)
once (one time) once The number 11 una vez

"Droga" is the classic safety trap. A patient who hears "droga" in a medication context may think you are asking about illegal substances. Ask "¿Qué medicamentos toma?" instead.

"Once" also works in reverse: a Spanish reader can read an English label that says "Take once daily" as "take 11 a day." Ask the pharmacy for a Spanish-language label when one is available, and confirm the number of doses with teach-back.

Tomar, tocar, llevar and other verbs

Spanish Meaning Common mistake
tomar take (swallow or drink a medicine), also to take a measurement Correct for pills and liquids: "tomar una pastilla"
tocar touch, or play (an instrument) Never use it for "take." A patient may hear "touch the pill"
llevar carry or bring "Take this to the pharmacy" is "lleve esto a la farmacia," not "tome"
dejar de + verb stop doing something "Deje de tomar" means stop taking
seguir + gerund keep doing "Siga tomando" means keep taking; "siga" alone can also mean "follow"
ponerse apply or put on "Póngase una gota" is common for eye drops

The stop and continue verbs deserve a second look. If the order is to stop a medicine, an unclear "siga" or "deje" can be heard as the opposite. Leave this wording to the interpreter and confirm with teach-back.

Frequency and timing wording

Frequency is where English and Spanish most often get mismatched.

English Spanish Pitfall
once a day una vez al día Clear. Says how many times
every day todos los días, cada día Says it is daily but not how many times
twice a day dos veces al día Not the same as "cada dos días" (every two days)
every 8 hours cada 8 horas Not always the same as "3 veces al día," which a patient may spread across waking hours
in the morning por la mañana "Mañana" alone can mean tomorrow
tomorrow mañana Say "mañana por la mañana" for tomorrow morning
at bedtime al acostarse Clear
on an empty stomach en ayunas Often understood as fasting, such as before breakfast. The order may mean a set time before or after meals, so give the exact timing through the interpreter

If the order says "every 8 hours," do not paraphrase it to "three times a day" unless the prescriber's order says so. Ask the prescriber when the schedule matters.

Measuring and forms

English Spanish Pitfall
teaspoon cucharadita Much smaller than a tablespoon
tablespoon cucharada Three times a teaspoon (about 15 mL vs 5 mL)
drops gotas Confirm the dropper or device
tablet / pill pastilla, tableta Words vary by region
capsule cápsula Clear
patch parche Confirm where and how often to change

"Cucharadita" and "cucharada" differ by one small suffix and by a factor of three, so mix-ups can matter. Kitchen spoons also vary in size. Give liquid doses in milliliters (mL) and show the oral syringe or dosing cup the pharmacy provides rather than relying on the word alone.

How to check understanding

Do not accept "sí" as an answer. Use open and show-me questions through the interpreter:

  • ¿Cuántas veces al día va a tomar este medicamento?
  • ¿A qué hora lo va a tomar?
  • ¿Qué va a hacer si se le olvida una dosis?
  • Muéstreme cuánto va a medir.
  • ¿Para qué es esta medicina?

For the method behind these questions, see our guide to teach-back: Discharge instructions in Spanish for nurses. A patient who parrots your sentence back without being able to explain it in their own words has not shown understanding.

When to stop and call the interpreter

Stop using your own Spanish and bring in a qualified interpreter when:

  • the patient asks a question you cannot answer in one short sentence
  • the medication is high-risk or has a complex schedule
  • the patient sounds unsure about timing, dose or purpose
  • you are about to say "stop," "continue," "double" or "skip" in Spanish

Family members should not interpret medication teaching. Their errors and their own stress can change the message.

Keep a quick reference

The Medical Spanish Pocket Guide is a quick reference for bedside Spanish. The Medical Spanish Kit adds badge cards, including a medications card, and flashcards for off-shift practice, designed by a family medicine physician & certified medical interpreter. These tools support basic communication and do not replace a qualified interpreter.
