All medicines have risks and benefits. Sometimes new risks are found even when a medicine has been used for many years. Your doctor has weighed the expected benefits of you taking UBISTESIN or UBISTESIN FORTE against the risks this medicine could have for you.

UBISTESIN and UBISTESIN FORTE contain the active ingredients: Articaine hydrochloride, a local anaesthetic to prevent the pain, and adrenaline (epinephrine) hydrochloride, a vasoconstrictor, which makes it last longer (adrenaline (epinephrine) narrows the blood vessels at the site of injection, which keeps the anaesthetic where it’s needed for a longer time) and controls bleeding during the surgery.

UBISTESIN and UBISTESIN FORTE belong to a group of medicines called local anaesthetics. UBISTESIN or UBISTESIN FORTE is injected into the mouth where it makes the nerves unable to pass messages to the brain.

Your dentist will have explained why you are being given UBISTESIN or UBISTESIN FORTE.

UBISTESIN and UBISTESIN FORTE are given by injection to cause loss of feeling before and during dental procedures.

Your dentist will explain to you why you are being treated with UBISTESIN or UBISTESIN FORTE and what dose you will be administered.

Your dentist will inject UBISTESIN or UBISTESIN FORTE into your oral (mouth) cavity. This will result in an area of numbness at the site of the injection.

One cartridge is usually sufficient but your dentist may give you a greater quantity. He will adjust the dosage according to your age, your health, your weight and the dental work to be performed. If only a portion of a cartridge is used the remainder must be discarded.


Your dentist will determine the amount of solution, which is needed to provide pain control during your treatment, and it is very unlikely that you would receive too much

However, some persons tolerate articaine and adrenaline (epinephrine) less well than others and the signs and symptoms of too much of these substances in your blood include: nervousness, dizziness, blurred vision, nausea, trembling, convulsions, slow or irregular heartbeat, troubled breathing.

Tell your dentist immediately if you experience any of these symptoms during or shortly after your treatment.


Things you must not do:

Do not eat or drink anything until the feeling has returned to your mouth. You may burn or bite yourself.

Things to be careful of:

  • Be careful driving or operating machinery until you know how it affects you. You may be drowsy and your reflexes may be slow. This medicine may cause dizziness, light-headedness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
  • Do not drink alcohol immediately before or after you are given it.
  • If you drink alcohol while you are being given it, your blood pressure may drop making you feel dizzy and faint.
  • Please talk to your dentist or pharmacist about these possibilities if you think they may bother you.


Tell your dentist as soon as possible if you do not feel well when using UBISTESIN or UBISTESIN FORTE.
