Indications
Mitargan is used as a strong and long-lasting antihistamine, with additional effects of reducing nausea and calming. Mitargan is indicated for the treatment of allergic conditions affecting the respiratory system and skin. Mitargan can also treat reactions to drugs or foreign proteins, including anaphylaxis. Mitargan is used for sedation, managing allergic rhinitis, hives, and insomnia. Additionally, Mitargan helps as a sedative before surgeries and in obstetrics. Mitargan is also used as a pediatric sedative.
Pharmacology
Mitargan is a type of medication that works by blocking certain receptors in the brain. Mitargan also has a strong effect on certain blood vessels and reduces the release of specific hormones. Mitargan competes with histamine to reduce allergic responses and may also block muscarinic receptors, which helps to prevent nausea. Mitargan is absorbed well through the digestive system and starts to work within 20 minutes, lasting for 4-6 hours, although Mitargan can last up to 12 hours. The body processes Mitargan in the liver into various compounds, and these are then excreted through the urine.
Dosage & Administration
Adults: The starting dose is one 25 mg tablet at night, which can be increased to two or three 25 mg tablets if needed. For allergic conditions, Mitargan may be taken two or three times a day, starting with one or two 10 mg tablets and adjusting as necessary.
Elderly: No specific dosage recommendations.
Children: Mitargan is better to use the elixir form, which has 5 mg per 5 ml.
For allergies:
- Children 2-5 years: 5-15 mg
- Children 5-10 years: 10-25 mg
For sedation:

The dose should be given at night.
Interaction
Mitargan may increase the effects of other medications that affect the nervous system, such as anticholinergics, antidepressants, sedatives, and alcohol. Mitargan can also interfere with urine pregnancy tests, causing false results. Mitargan should be stopped at least 72 hours before skin allergy tests as Mitargan may affect the response, leading to false-negative results.
Contraindications
Mitargan is not recommended for children under two years old or for those who are allergic to Mitargan or any of its ingredients. Mitargan should not be used in patients in a coma or those with severe depression of the nervous system. Mitargan should not be given to premature infants or neonates. Mitargan must be avoided by patients who have taken monoamine oxidase inhibitors in the last 14 days.
Side Effects
Possible side effects include drowsiness, dizziness, headaches, muscle spasms, or involuntary movements of the face. In rare cases, a severe condition called neuroleptic malignant syndrome (NMS) may occur, which requires immediate medical attention. Other effects can include allergic reactions, skin sensitivity to light, loss of appetite, stomach discomfort, dry mouth, blurred vision, blood problems, urinary issues, and confusion in young children. More serious issues like irregular heartbeats and liver problems can also occur.
Pregnancy & Lactation
Mitargan is generally considered safe during pregnancy, though Mitargan should only be used if the doctor thinks Mitargan’s absolutely necessary. Mitargan is not recommended in the two weeks before delivery because Mitargan may cause irritability and excitement in the newborn. Mitargan should be avoided during late pregnancy as Mitargan could cause neurological problems in the infant. Mitargan can pass into breast milk and may cause irritability in the baby.
Precautions & Warnings
