- USES
-
- Protriptyline is used to relieve the symptoms of mental depression. This
- medication belongs to a group of drugs referred to as the tricyclic
- antidepressants. These medicines are thought to relieve depression by
- increasing the concentration of certain chemicals necessary for the
- transmission of nerve impulses in the brain. This drug may also be used in
- the treatment of certain sleep disorders.
-
- TREATMENT
-
- This medication should be taken exactly as your doctor prescribes. You
- can take it with water or with food to lessen the chance of stomach
- irritation, unless your doctor tells you to do otherwise.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, then return to your regular dosing schedule. However, if the dose
- you missed was a once-a-day bedtime dose, do not take that dose in the
- morning; check with your doctor instead. If the dose is taken in the morning,
- it may cause some unwanted side effects. Never double the dose.
- The effects of therapy with this medication may not become apparent for
- two or three weeks.
-
- SIDE EFFECTS
-
- Minor.
-
- Anxiety, blurred vision, constipation, cramps, diarrhea, dizziness,
- drowsiness, dry mouth, fatigue, headache, heartburn, insomnia, loss of
- appetite, nausea, peculiar tastes in the mouth, restlessness, sweating,
- vomiting, weakness, or weight gain or loss. As your body adjusts to the
- medication, these side effects should disappear.
- This medication may increase your sensitivity to sunlight. You should,
- therefore, avoid prolonged exposure to sunlight and sunlamps. Wear protective
- clothing, and use an effective sunscreen.
- If you experience dry mouth, you should try chewing sugarless gum or
- sucking on ice chips or a piece of hard candy.
- To relieve constipation, increase the amount of fiber in your diet (fresh
- fruits and vegetables, salads, bran, and whole-grain breads), exercise, and
- drink more water (unless your doctor directs you to do otherwise).
- To avoid dizziness or light-headedness when you stand, contract and relax
- the muscles of your legs for a few moments before rising. You can accomplish
- this by pushing one foot against the floor while raising the other foot
- slightly, alternating feet so that you are "pumping" your legs in a pedaling
- motion.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- agitation, bleeding, chest pain, confusion, convulsions, difficulty in
- urinating, enlarged or painful breasts (in both sexes), fainting, fever, fluid
- retention, hair loss, hallucinations, headaches, impotence, mood changes,
- mouth sores, nervousness, nightmares, nosebleeds, numbness in the fingers or
- toes, palpitations, ringing in the ears, seizures, skin rash, sleep disorders,
- sore throat, tremors, uncoordinated movements or balance problems, or
- yellowing of the eyes or skin.
-
- INTERACTIONS
-
- Protriptyline interacts with a number of other types of medications:
- 1. Extreme drowsiness can occur when this medicine is taken with central
- nervous system depressants (medicines that slow the activity of the brain and
- spinal cord), including alcohol, antihistamines, barbiturates, benzodiazepine
- tranquilizers, muscle relaxants, narcotics, pain medications, phenothiazine
- tranquilizers, and sleeping medications, or with other tricyclic
- antidepressants.
- 2. Protriptyline may decrease the effectiveness of antiseizure
- medications and may block the blood-pressure-lowering effects of clonidine and
- guanethidine.
- 3. Oral contraceptives (birth control pills) or estrogen-containing drugs
- can increase the side effects and reduce the effectiveness of tricyclic
- antidepressants (including protriptyline).
- 4. Tricyclic antidepressants may increase the side effects of thyroid
- medication and over-the-counter (nonprescription) cough, cold, allergy,
- asthma, sinus, and diet medications.
- 5. The concurrent use of tricyclic antidepressants and monoamine oxidase
- (MAO) inhibitors should be undertaken very carefully, because the combination
- may result in fever, convulsions, or high blood pressure.
- Before starting to take protriptyline, BE SURE TO TELL YOUR DOCTOR about
- any medications you are currently taking, especially any of those listed
- above.
-
