From the Research
Side Effects of Blue Chew
- Blue Chew is a formulation of sildenafil or tadalafil, which are phosphodiesterase type 5 inhibitors (PDE5i) used to treat erectile dysfunction (ED) 3, 4, 5, 6, 7
- Common side effects of PDE5i include headache, facial flushing, and gastrointestinal upset, but the specific side effects of Blue Chew are not well-documented in the provided studies
- Priapism, a condition characterized by a prolonged and painful erection, is a rare but potentially serious side effect of PDE5i, including sildenafil and tadalafil 4, 5, 7
- The risk of priapism may be higher in younger patients, with a study finding that the 12-17 years age group had the highest reporting odds ratio (ROR) for priapism associated with PDE5i use 7
Comparison of Sildenafil and Tadalafil
- Sildenafil and tadalafil have similar efficacy and safety profiles, but some studies suggest that patients may prefer one over the other due to differences in factors such as dosage, side-effect severity, and satisfaction with erection hardness 6
- A study found that 71% of patients preferred tadalafil, while 29% preferred sildenafil, with the preference being associated with factors such as time concerns, dosage choice, and treatment tolerability 6
