Copy from the pack in hand
Source-linked reading points
- Check SYNTHROID, levothyroxine, the mcg strength per tablet, actual package and target market first. mcg (micrograms) and mg (milligrams) are different units: 1 mg equals 1,000 mcg. Similar-looking units must not be used to convert tablet count by experience.
- Different colours, mcg strengths, brands or market packs are different product-identity clues. Even when both say “thyroid hormone,” they do not establish self-equivalent substitution, split-and-combine use or alternation.
- The label addresses absorption-related issues with food, mineral supplements, antacids and multiple medicines. With calcium, iron, stomach medicines, lipid medicines, anticoagulants or multiple chronic-care products at home, bring the complete medicine list for pharmacist or prescribing-team review.
- Fatigue, palpitations, weight or sleep changes cannot be attributed by a webpage and used to self-adjust. Starting, tapering, make-up use, conversion or any concerning symptom needs the current label, testing and specific professional judgement.
