How to Pronounce Tretinoin
"The dermatologist prescribed tretinoin cream to reduce acne lesions."
"During the lecture, he demonstrated how tretinoin affects skin cell turnover."
"She discussed potential irritation side effects from tretinoin and recommended moisturizers."
Pronounce as /ˈtrɛt.ɪ.nɔɪn/. Put the stress on the first syllable: TRET.ih.noyn. The middle syllable is a quick, light /ɪ/ plus /n/. The final is /ɔɪn/, like ‘coin’ with an N. Tip: say 'TRET-ih-noin' in a smooth three-beat flow, ending with a light nasal.”,
Common errors: misplacing stress (saying tre-TI-noin), and mispronouncing the final /ɔɪn/ as /ɔːn/ or /oɪn/. Some speakers insert an extra vowel sound in the middle (tro-tin-oin). Correction: keep primary stress on the first syllable, crisp /ɪ/ in the second, and ensure the final /ɔɪn/ rhymes with coin. Practice slowly: /ˈtrɛt.ɪ.nɔɪn/ and gradually speed up.”,
US/UK/AU share /ˈtrɛt.ɪ.nɔɪn/ with the final /ɔɪn/ closely matching ‘coin.’ Australians may slightly reduce the /ɪ/ in the second syllable to a schwa in rapid speech: /ˈtrətˌnɔɪn/ while still keeping the primary stress on the first syllable. Rhoticity does not alter the core vowels here; vowel quality differences are minor compared to the neutral treatment of /ɪ/ and /ɔɪ/. Overall, maintain the three distinct syllables across accents.”,
Three phonetic features challenge speakers: the two short vowels /ɛ/ and /ɪ/ in the early syllables and the diphthong /ɔɪ/ in the last. The transition from a light /t/ to a vowel can cause a clipped second syllable. The final /ɔɪn/ requires precise tongue positioning to avoid turning it into /ɔːn/ or /ɒn/. Practicing with slow repetitions and listening to medical reading helps solidify the rhythm and final diphthong.”,
Tretinoin carries a three-syllable, stress-bearing sequence with a specific diphthong at the end. The key is the contrast between the brief /ɪ/ in the middle syllable and the long, rising /ɔɪ/ diphthong at the end. Unlike other drug names with silent letters or heavily compounds, tretinoin is phonemically straightforward once you guide the mouth through a steady, three-beat articulation: /ˈtrɛt.ɪ.nɔɪn/.

Tretinoin originated from its chemical structure and class. The root ‘retino-’ traces to retinol (Vitamin A) and related compounds that influence cell differentiation. The suffix ‘-in’ marks a chemical substance, common in pharmaceutical agents. The name likely combines ‘trans-’ or ‘all-trans’ descriptors used to indicate stereochemistry and the retinoid family; historical naming often reflects structural features rather than therapeutic action. First used in the late 1950s to 1960s during the expansion of retinoid research, tretinoin gained medical prominence as a topical acne treatment and later for other dermatologic indications. Over decades, its usage extended to systemic administration in specific dermatologic conditions, with the name persisting as a distinct compound within the retinoid catalog. The pronunciation’s standardization aided global medical communication as prescriptions and product labeling expanded internationally.
