  • Androgel for secondary hypogonadism
    Severe swelling in legs, ankles and feet after being on my feet for more than one hour. Pain in calves and ankles. Feels like they're being squeezed or compressed. Pain dissipates after laying down for a few hours. Swelling never completely dissipates. Always some swelling in ankles.
  • Migraine with dyazide
    Took Dyazide for blood pressure escalating due to Cyclosporine. Have history of bad migraines but have not had them routinely for many years. Within 24 hours of starting treatment with Dyazide, severe headache began that lasted throughout the day and eventually led to ER treatment. Was told to no longer take Dyazide, headache did not return. Was 49 at time of ER treatment and was on Dyazide for 1 week.
  • Tiredness on citalopram and cetirizine
    Extreme tiredness......sleep more sleep and slight confusion when I a zombie mode switched on inside my head ...all I can do is yawn and sleep not good when your a busy mum
  • Effexor xr 150 mg and phentermine 37.5 mg
    phentermine has caused significant weight loss. Effexor XR manages my GAD and depression but causes random physiological anxiety attacks, drastic increase in sweating, vivid and nightly nightmares
  • Neulasta side effect
    Day 7 post neulasta injection, experienced 24-36 hours of intense nausea, vomiting, and bone pain.
