Hello
Side effects are NOT an an Absolute kind of phenomenon. This means there is no rule that each patient will have every side effect. A major chunk of patients escape most side effects.
The more common side effects like nausea and vomiting are common that too only for the first 3-5 days.
There is absolutely no way of predicting whether such short duration wil lead to any sexual side effect all.
Next Steps
