1. What is Relfydess and what is it used for

Relfydess contains a substance, botulinum toxin type A, that causes muscles to relax. This medicine works by inhibiting nerve impulses in the muscles into which it is injected, preventing muscle contraction.

Relfydess is indicated for the temporary improvement of moderate to severe vertical lines between the eyebrows (glabellar lines) and lateral periorbital lines of moderate to severe severity (lateral canthal lines, also known as crow's feet). It is used in adults under 65 years of age, when these facial lines have a significant impact on the patient's well-being.

2. What you need to know before you use Relfydess

Do not useRelfydess:

• if you are allergic to botulinum toxin or any of the other ingredients of this medicine (listed in section 6)
• if you have an infection at the proposed injection site
• if you have severe myasthenia gravis, Eaton-Lambert syndrome, or amyotrophic lateral sclerosis (chronic diseases that affect the muscles)

Warnings and precautions

Consult your doctor before starting treatment with Relfydess:

• if you have any disorder that affects your nervous system
• if you feel weak, lack strength and energy
• if you have difficulty breathing
• if you have difficulty swallowing food or often have problems with food or drink entering your airways, causing choking or coughing
• if you have previously experienced side effects with other botulinum toxin injections and/or have not experienced significant improvement after the last treatment
• if you have any inflammation at the proposed injection site
• if you have eye problems, including dry eye and drooping eyelids
• if the muscles to be injected are weak or show signs of atrophy
• if you have any coagulation disorder, meaning you may bleed more than normal, or are taking anticoagulant medications

This information will help your doctor make a decision about the risks and benefits of your treatment.

Special precautions

Very rarely, botulinum toxin can cause side effects far from the injection site (e.g., difficulty swallowing, coughing, and choking, difficulty speaking or breathing). These symptoms have been observed from hours to weeks after injection.

Seek medical attention immediately if you experience difficulty swallowing, speaking, or breathing.

The use of Relfydess may cause dry eyes. If you experience symptoms of dry eyes (such as eye irritation, sensitivity to light, or visual changes), consult your doctor.

Repeated treatments with botulinum toxin may result in muscle atrophy due to temporary paralysis of the treated muscles.

When botulinum toxin has been used at too frequent intervals or with excessive doses, it can lead to the formation of antibodies. The formation of neutralizing antibodies can reduce the effectiveness of treatment.

Children and adolescents

Relfydess is not recommended for use in persons under 18 years of age.

Other medicines and Relfydess

Tell your doctor if you are taking, have recently taken, or might take any other medicines. In particular, tell your doctor about the following medicines, as they may increase the effect of Relfydess:

• certain antibiotics to treat infections (e.g., aminoglycosides)
• other muscle relaxants
• other medicines that contain botulinum toxin

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before using this medicine.

Relfydess should not be used during pregnancy, or in women of childbearing potential who are not using contraceptive methods or are breastfeeding.

Driving and using machines

You may experience blurred vision or temporary muscle weakness after treatment with Relfydess. If this happens, do not drive or use machines.

Relfydess contains potassium, sodium, and polysorbate

This medicine contains potassium, less than 1 mmol of potassium (39 mg) per vial of 150 units; this is essentially "potassium-free".

This medicine contains less than 1 mmol of sodium (23 mg) per vial of 150 units; this is essentially "sodium-free".

This medicine contains 1.6 mg of polysorbate 80 per vial of 150 units, which is equivalent to 1.1 mg/mL. Polysorbates can cause allergic reactions. Tell your doctor if you have any allergies.

3. How to use Relfydess

Relfydess should only be administered by doctors with the appropriate qualification and experience in this treatment and who have the appropriate equipment. Your doctor will inject Relfydess into the muscles intended for treatment.

The units of Relfydess are specific and are not interchangeable with other botulinum toxin preparations.

The recommended dose of Relfydess is:

• For vertical lines between the eyebrows: 50 units (0.5 mL). You will be injected with 10 units (0.1 mL) at each of the 5 injection points located on the forehead above your nose and eyebrows.
• For lateral canthal lines around the eyes:60 units (0.6 mL). You will be injected with 10 units (0.1 mL) at each of the 6 injection points. These 6 injection points include 3 injection points on each side of the face, in the crow's feet area.
• For combined treatment: the same doses are recommended, i.e., 50 units for the treatment of glabellar lines and 60 units for the treatment of lateral canthal lines, for a total of 110 units (1.1 mL).

The effect of the treatment usually occurs within a few days after injection and can last 6 months. The interval between Relfydess treatments will be decided by your doctor. The interval between two treatments should not be less than 3 months.

If you use more Relfydess than you should

Since the treatment is administered by a doctor with the appropriate qualification and experience, it is unlikely that you will be given too much medicine. However, if you receive more Relfydess than necessary, other muscles different from those treated may begin to weaken. Excessive doses can cause difficulty swallowing, speaking, and breathing problems. This may not happen immediately. If these symptoms appear, inform your doctor as soon as possible.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Seek urgent medical attention if:

• You experience difficulty breathing, swallowing, or speaking
• You have inflammation, including inflammation of the face or throat, hives, wheezing, feeling faint, or shortness of breath. You may be experiencing an allergic reaction to Relfydess.
