1. What HerpMed Labiale is and what it is used for
HerpMed Labiale contains the active substance aciclovir and belongs to a group of medicines called antivirals.
HerpMed Labiale is used for the treatment of recurrent episodes of cold sores caused by the Herpes simplex virus in adults with a healthy immune system. HerpMed Labiale should be applied directly to the gum as soon as the first symptoms (burning, tingling, and itching) or signs (redness and swelling) appear.
The virus causes blisters or ulcers, mainly on the lips, but sometimes in other parts of the face. Viral infection may be triggered when the immune system is weakened, for example by colds or other infections. Strong sunlight, stress, or the menstrual cycle may also trigger symptoms.
HerpMed Labiale inhibits the virus's ability to replicate, thereby helping the infection to subside.
If you do not feel better or if your symptoms have not improved after 5 days, you must consult your doctor.
2. What you need to know before using HerpMed Labiale

- If you have a weakened immune system (due to another disease affecting the immune system, such as AIDS, or due to treatment affecting your immune system, e.g. immunosuppressive drugs), talk to your doctor before using this medicine. HerpMed Labiale should not be used in such cases.
- It is not known whether HerpMed Labiale is effective when used after blisters have already appeared. Therefore, you should use HerpMed Labiale only after noticing the first symptoms of cold sores (itching, redness, or tingling).

Instructions for appropriate use
This medicine should be applied to the upper gum, above a front tooth, as soon as the first symptoms or signs of cold sore appear (such as itching, redness, or tingling):
- Before applying the tablet, locate the area on the upper gum above the front tooth.
- Apply one tablet using a dry finger immediately after removing it from the blister. As you can see, the tablet has one rounded side and one flat side bearing the inscription "AL21".
- For greater comfort, apply the rounded side to the upper gum, although either side of the tablet may be used.
- If your mouth is dry, it is recommended to drink water to moisten the gum before applying the tablet. The tablet may be used if it adheres inside the lip instead of on the gum. Once applied, the tablet stays in place and gradually dissolves throughout the day.
How to apply HerpMed Labiale
- Hold the tablet in place by applying gentle pressure with your finger on the outside of the upper lip for 30 seconds to ensure adhesion.
Food and drinks can be consumed normally while HerpMed Labiale is in place. The tablet must not be sucked, chewed, or swallowed.
All situations that could interfere with tablet adhesion should be avoided, such as:
- touching or pushing the tablet after application
- chewing gum
- brushing teeth during the day while the tablet is in place.
If this medicine does not adhere or comes off within the first 6 hours, the same tablet must be repositioned immediately. If the tablet cannot be repositioned, a new tablet must be applied.
If a HerpMed Labiale tablet is accidentally swallowed, drink a glass of water. If the tablet is swallowed within 6 hours after application, it should be replaced only once.
If HerpMed Labiale comes off or is accidentally swallowed after 6 hours, there is no need to replace the tablet.
The shape of the tablet may change as a result of saliva absorption and adaptation to the shape of your gum.
If you use more HerpMed Labiale than you should
Contact your doctor or pharmacist immediately, although the risk of overdose is low due to the limited absorption of aciclovir into the bloodstream following administration of HerpMed Labiale.
