Acyclovir Ointment Side Effects
Common side effects of acyclovir ointment include mild pain (such as temporary burning and stinging), itching, and swelling at the application site. These side effects are typically minor and easily treated. However, notify your healthcare provider right away if you notice a severe rash or severe itching, as these acyclovir ointment side effects may be symptoms of an allergic reaction.
An Introduction to Acyclovir Ointment Side EffectsAs with any medicine, side effects are possible with acyclovir ointment (Zovirax® ointment). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with acyclovir ointment. Your healthcare provider can discuss a more complete list of acyclovir ointment side effects with you.)
Common Acyclovir Ointment Side EffectsAcyclovir ointment has been studied thoroughly in clinical trials, in which the side effects of a group of people taking the drug are documented and compared to another group not taking the medicine. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, the most common side effects of acyclovir ointment included:
- Mild pain (including temporary burning and stinging) -- in up to 30 percent of people
- Itching -- up to 4 percent.
Other reported side effects of acyclovir ointment included swelling of the skin (rashes) where the medication was applied. Tell your healthcare provider if you experience a severe rash, severe itching, or a rash that spreads beyond the area where the medication was applied, as these may be signs of an allergic reaction.
