No.
Harvoni and Twinvir are no different. My dizziness comes and goes. Its related to the elevated BP that I have since starting on Harvoni. The meds do help but sometimes Harvoni just takes over.
Harvoni effects each person differently. There are sides but lesser when compared to ribavrin.
The common symptoms are tiredness, headache, the extras may vary like dark urine, chest pain, elevated BP, Dizziness, shortage of breath, insomnia, diarrhea, muscle pain, itching, dryness in lower legs and feet, ankle and feet swelling, eczema, pitting edema...
Gilead just mention 3-4 of the above so lets not believe it all what their sales brochure says.
