Yes, such a small amount of phenylephrine is of no consequence. It has a low oral bioavailability and because of that fact the acute oral toxicity is lower for phenylephrine than similar drugs such as pseudoephedrine. To give you idea of how low its oral toxicity is, in rats it would take an enormous 150 mg/lb of body weight to be life-threatening. Please respond with further questions or concerns if you wish.
