Precautions while using Surmontil

It is very important that your doctor check your progress at regular visits to allow for changes in your dose and to check for any unwanted effects.

Do not take trimipramine with a monoamine oxidase (MAO) inhibitor (for example, isocarboxazid [Marplan®], linezolid (Zyvox®), methylene blue injection, phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking trimipramine during the 2 weeks after you stop a MAO inhibitor and wait 2 weeks after stopping trimipramine before you start taking a MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.

Trimipramine may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use trimipramine with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, St. John's wort, or some pain or migraine medicines (for example, rizatriptan, sumatriptan, tramadol, Frova®, Imitrex®, Maxalt®, Relpax®, Ultram®, Zomig®). Check with your doctor first before taking any other medicines with trimipramine.

For some children, teenagers, and young adults, this medicine can increase thoughts of suicide. Tell your doctor right away if you start to feel more depressed and have thoughts about hurting yourself. Report any unusual thoughts or behaviors that trouble you, especially if they are new or get worse quickly. Make sure the doctor knows if you have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also tell the doctor if you have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.

Do not stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a possible worsening of your condition and reduce the possibility of withdrawal symptoms such as headache, nausea, or a general feeling of discomfort or illness.

This medicine may cause some people to become dizzy or drowsy. Make sure you know how you react to this medicine before you drive, use medicines, or do anything else that could be dangerous if you are drowsy or not alert.

Before having any kind of surgery, tell the medical doctor in charge that you are using this medicine. Taking trimipramine together with medicines used during surgery may increase the risk of side effects.

This medicine may affect blood sugar levels. If you are diabetic and notice a change in the results of your blood or urine sugar tests, check with your doctor.

This medicine will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that cause drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. This effect may last for a few days after you stop taking this medicine. Check with your doctor before taking any of the above while you are using this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Before using Surmontil

In deciding to use a medication, the chances of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Inform your physician if you have ever had any unusual or allergic reaction to this medication or any other medicines. Additionally inform your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of trimipramine in the pediatric population. Safety and efficacy have not been established.

Geriatric

Although appropriate studies on the relationship of age to the effects of trimipramine have not been performed in the geriatric population, no geriatric-specific issues have been documented to date. Nevertheless, elderly patients are more likely to have unwanted effects (eg, confusion or unusual drowsiness) or age-related liver or kidney problems, which may require caution and an adjustment in the dose for patients receiving trimipramine.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medicine during breastfeeding. Weigh the potential benefits against the potential chances prior to using this drug while breastfeeding.
