Forteo side effects of fatigue and mild confusion

I had fatigue with Tymlos, a similar drug, for the hours after injecting, and found that getting up and out actually helped even though I wanted to rest. I would take a walk if I had nothing else to do. My theory was tate the meds lower blood pressure and cause us to feel tired, and maybe activity raises blood pressure. I also hydrated and sometimes ate salty things before the shot.

Long term fatigue over the two years may be a different matter but even with that (mine was low level) getting up and out helped. If I stayed in bed to watch Netflix I got more tired!

Good morning, I was incredibly tired for 4-6 weeks after starting teraparatide, plus I was getting heart palpitations. Thankfully my body got used to the drug, and I’m now symptom free. My bone markers after being on it for 3.5 months look very promising for a good outcome, so I’m glad I stuck with it. I hope your body adapts as mine did, but if it doesn’t you may want to consider another alternative as the tiredness I personally was experiencing would have been too much for two years.

Thank you for your reply. It will be a month at the end of the week so I am going to keep with it. Also experience some heart palpitations (not severe) and some confusion.

@elaussies I got a blood pressure cuff and made sure to hydrate (and sometimes ate salty chips). Monitoring my blood pressure helped. I believe that low bp can cause palpitations and tiredness and Forteo and Tymlos both lower bp for up to a few hours, as I remember.

May not be relevant for you but for me the blood pressure cuff let me know more about what was going on. Again I ultimately went down to 1/4 dose and moved slowly up toward full dose.

Thank you ! May try to reduce dosage

Hi @elaussies i also experienced noticable fatigue and tiredness during my first couple months of Forteo therapy. It was most likely due to the fact that Forteo impacted my blood pressure - reducing it from 90s/60s to low80s/low50s. My endo advised me to increase hydration (from 8 cups to 10 cups, or 2000cc to 2400cc) and add some salt to the water if needed. I did monitor my blood pressure throughout the day. It appeared my blood pressure was low all day long 24/7 so was my fatigue. Admittedly i couldnt do much at all during first one and half months. Luckily my body adjusted and I felt myself toward the end of 2nd month.

Please note that Forteo pen is not adjustable. The clicks that you hear is not calibrated with any corresponding dose. The full dose 20mcg is approved minimal effective dose.

If your symptoms remain intolerable after readjusting hydration level, it may be a good idea to communicate with your physician regarding this.

Blood pressure cuff, hydrate, potato chips- or Gatorade!

Thank you for the reply. Much appreciated!

I've been on it for 2 months and I experienced a lot of fatigue in the evenings but before I took my dose. I'm planning to have bloods done to check for too high levels of calcium. I had stopped my multi vitamin as my endo didn't want me taking Vitamin D. I've gone back to taking a multivitamin every two days and I am less tired. I don't know if I was missing some other vitamin or if I am adapting to the drug.

@paulta why does your endo say not to take Vitamin D? Were your levels too high?
