How To Tenutex Cream Uses

Always use this medicine exactly as described in this leaflet or as directed by your doctor, pharmacist, or nurse. Ask your doctor or pharmacist if you are unsure.

Accurate diagnostics, contact tracing, and well-executed treatment are of great importance for a successful outcome.

HEAD LICE

In the case of head lice, the whole family should be examined, but treat only the people who have lice or eggs near the scalp. The examination requires a louse comb and magnifying glass. As the agent is potent and reduces the risk of developing resistance, treatment should be avoided “just in case”.

Part the towel-dried hair in the middle and place a strand of Tenutex in the part. Massage out towards the sides. Add new legs to the right and left and drench the hair (consumption depending on hair length, 25-75g) from the inside out – it is at the scalp that the lice live and lay eggs. Avoid getting Tenutex cream near the eyes. Wash and comb your hair after a day.

To get rid of the lice, treatment is usually required twice with Tenutex Cutaneous Emulsion, 8 days apart, in combination with daily careful combing of the hair. Fine comb and inspect hair daily for 14 days after treatment.

If desired, you can wear a knitted cap or similar over your hair during the treatment period – but not an airtight one, such as a swimming cap or plastic bag. Since infection mainly occurs through head-to-head contact, there is no need for extensive cleaning and cleaning of objects. However, cleaning of combs, brushes, and caps is recommended.

Lack of effect may be due to incorrect treatment, re-infection, or resistance. Children who have recently been infected and adults with lice often have no symptoms, and can therefore be an important source of infection. Note that it takes a while for the lice to die, which is why finding live lice immediately after treatment does not have to be a sign of resistance.

Contact healthcare if repeated treatment attempts fail.

FLAWLESS

Talk to a doctor or nurse before using Tenutex to treat flat lice.

Massage the chest, armpits, and other hairy areas of the body (e.g. legs) with Tenutex. As a rule, the head hair does not need to be treated, but should the lice appear there, it is treated as for head lice. Tenutex must not be used around the eyes. In the case of flat lice in eyelashes, a doctor should therefore be contacted. Wait with all body washes for 2 days after the Tenutex treatment.

SCABIES

Talk to a doctor or nurse before using Tenutex to treat scabies.

  1. Thorough body wash. Dry well.
  2. Carefully massage the whole body – except the head – with Tenutex (50-60 g). Only on babies does the head also need to be treated, avoid getting Tenutex near the eyes. Avoid excessive rubbing. ATTENTION! Don’t forget to lubricate the soles of your feet and between your toes and fingers. Every square millimeter of the body must be covered by the ointment for 24 hours.
  3. Wait a day with all body wash. Use rubber gloves, which are then thrown away, when doing dishes and other wet work. Lubricate your hands again with Tenutex cream after work and also after each hand wash.
  4. Wash the body thoroughly 1 day after the treatment. Change all clothing closest to the body, change bed linen, all towels, bath towels, etc. All textiles and shoes that have been in close contact with the body must be washed or aired for 3-5 days.
  5. In severe cases of scabies, the treatment (according to points 1-4) is repeated after a week.

If you have any further questions about this medicine, ask your doctor, pharmacist, or nurse.
