Ay sis, this is definitely a doctor question, thyroid conditions need proper medical check-up and the right prescription, kaya please consult her OB or internist para ma-adjust ang dosage based sa kanyang condition, lalo na if she's pregnant or planning to get pregnant. A few of us moms have friends with thyroid issues, at lahat sila kailangan ng regular monitoring lang, so don't worry, it's manageable with professional guidance! What matters is she gets checked soon para ma-rule out any concerns for baby. Sending you strength, mama!
