Calcitonin plays a critical role in maintaining the balance between bone formation and resorption. It's a hormone that's produced in our thyroid gland. When released, it helps in reducing bone resorption, which is the process where our bones are broken down, and the minerals within them, like calcium, are released into the bloodstream. By doing this, calcitonin indirectly promotes bone formation by preventing bone loss. Therefore, it's essentially a protective mechanism to ensure our bones stay strong and healthy.
Hormonal Influence: How Hormones Change Medications, Tests & Symptoms
Hormones tweak many things in your body — how you feel, how drugs work, and what your blood tests show. If you have thyroid issues, are pregnant, on birth control, or using steroids, a few small checks can prevent big problems. This page groups practical tips and clear warnings so you can make smarter choices about meds and tests.
Why hormones matter for medicines
Hormones change drug levels and effects in predictable ways. For example, thyroid status alters how your liver processes several drugs: untreated hypothyroidism can raise cholesterol and sometimes change how your body handles statins or blood thinners. Birth control pills interact with the liver too and can change levels of some anti-seizure drugs. Pregnant bodies increase blood volume and speed up some drug clearances, so doses that worked before pregnancy might need an update.
That doesn’t mean every medicine fails when hormones shift. It means watch for warning signs: dizziness, new fatigue, mood swings, heavier bleeding, or unexplained weight changes. Those are signals your dose or test timing might need attention.
Simple steps you can take right now
Start with open talk. Tell your doctor and pharmacist about thyroid problems, hormone therapy, pregnancy plans, or contraceptive methods. Ask whether your meds need blood checks and when to schedule them. A few concrete steps can avoid surprises:
- Get a baseline blood test (TSH, drug levels, liver tests) if you start or stop hormone therapy.
- If pregnant or planning pregnancy, review all prescriptions — some are unsafe or need dose changes.
- When starting/stopping hormonal birth control, mention it when your provider prescribes antiseizure drugs, antidepressants, or heart meds.
- Watch for new side effects after hormone changes and report them quickly.
Monitoring is cheap compared with fixing avoidable complications. For example, thyroid workups often explain rising cholesterol or tiredness instead of reflexively adding another drug.
Medications can also affect hormones. Some antidepressants and antipsychotics change weight or sexual function. Certain cholesterol drugs and blood pressure meds may nudge hormone-related lab numbers. If a medicine affects your mood, libido, or menstrual cycle, don’t shrug it off — bring it up.
Pregnancy and breastfeeding deserve extra care. Some drugs cross the placenta or appear in breast milk. Others are safe only after dose adjustments. If you’re pregnant or breastfeeding, never change meds yourself. Ask a clinician who knows pregnancy safety rules.
Finally, keep a simple record: meds, doses, dates you started/stopped hormones, and any symptoms. That log speeds up problem-solving and keeps everyone on the same page.

Hormones shape health more than most people realize. A few practical checks and honest conversations with your provider will keep treatments working and reduce risk. If something feels off after a hormonal change, act early — small adjustments often fix it fast.
