The first sign is an unusual paleness of the skin, followed by yawning, restlessness and a cold sweat, according to the experts.

Tell your doctor immediately if any of these rare but very serious side effects occur: signs of infection (e.g., fever, persistent sore throat), unusual paleness, unusual tiredness, fast/pounding/irregular heartbeat, yellowing of the eyes/skin, dark urine.

Symptoms in the fingers include unusual paleness, absence of color (pallor), and/or a red or bluish color to the skin (cyanosis).
