The most common side effects of generic Diflucan medication are headache, nausea, and stomach pain; though diarrhea, skin rashes, and effects on the sense of taste are also fairly common. In very rare cases, allergic reactions result in severe tissue swelling (angioedema), so patients should carefully monitor their condition once they buy Diflucan. It has also been associated with liver problems such as jaundice and hepatitis, but the nature of the association is unclear and these reactions are not common. It is usually not recommended to buy Diflucan for pregnant women or women that are actively breast feeding due to potential effects on the fetus or infant.
