Such patients also should be cautioned about the simultaneous consumption of alcohol and other brain depressive drugs.

Depression or anxiety

Patients taking Alprox

Patients using Alprox may have a risk of withdrawal symptoms including prolonged seizures that can be possibly fatal.

Symptoms occur between dose intervals

Patients using Alprox may have a risk of early morning anxiety which may indicate the development of tolerance. The same total daily dose of Alprox should be given in divided doses to such patients.

Risk of dose reduction

The reduction of dose in patients using Alprox may have a risk of withdrawal reactions. The doses of Alprox should be decreased and stopped gradually.

Use of opioids

Patients using Alprox with opioids are at an increased risk. Such patients may have an increased risk of sleepiness, coma, breathing problems, and can be fatal.

Interactions with Alprox

When two or more medicines are taken together, it can change how the medicines work and increase the risk of side-effects. In medical terms, this is called as a Drug Interaction.
Alprox Tablet interacts with imipramine and desipramine, which are used to treat depression. An increased amount of imipramine and desipramine in the blood have been reported when used simultaneously with Alprox.
There may be an interaction of Alprox with other brain depressants (CNS depressants). Alprox produces an additive effect when used with other brain depressants (CNS depressants) such as psychotropic medicines, neuroleptics, hypnotics, anti-anxiety drugs, sedatives, antidepressants, narcotic analgesics, anesthetics, anticonvulsants, and antihistamines. The patient should be cautious when using Alprox with other brain depressants (CNS depressants).
Alprox Tablet may interact with opioids, which are used to relieve pain. The use of benzodiazepines and opioids together increases the risk of sedation, breathing insufficiency, coma, and can be possibly fatal because of additive brain depressant (central nervous system depressant) effect. It may also cause an increase in the experience of happiness or excitement which can lead to more mental dependence. If benzodiazepines and opioids are used together, limit the dosage and duration of treatment. Monitor the patients strictly for breathing insufficiency and sedation.
Your doctor's guidelines may need to be followed while taking this medicine along with digoxin, which is used to treat heart failure. When Alprox is used with digoxin, increased digoxin amount has been reported in the blood, especially in elderly aged more than 65 years. The patients who receive Alprox and digoxin should be monitored for signs and symptoms of increased digoxin levels in the blood.
Special instructions need to be followed while taking this medicine along with liver enzyme (CYP3A) inhibitors. The use of Alprox with enzyme CYP3A inhibitors may increase the amount and activity of Alprox in the blood. The patients should be cautious while using Alprox with cytochrome P450 3A inhibitors, such as fluoxetine, propoxyphene, oral contraceptives, sertraline, diltiazem, or macrolide antibiotics like erythromycin, clarithromycin, and troleandomycin.
Your doctor's guidelines may need to be followed while taking this medicine along with cimetidine, which is used to treat heartburn and stomach ulcers. The use of Alprox with cimetidine increases the amount of Alprox in the blood. While using Alprox with cimetidine, precaution and dose reduction of Alprox is recommended.
Special instructions need to be followed while taking this medicine along with nefazodone or fluvoxamine, which are used to treat depression. The use of nefazodone or fluvoxamine with Alprox cause a two-time increase in the level of Alprox in the blood and a decrease in psychomotor performance. The patients should be cautious while using Alprox with nefazodone or fluvoxamine and dose reduction is also recommended.
Alprox Tablet interacts with azole-type antifungals (for example, ketoconazole, itraconazole), which are used to treat fungal infection. The use of Alprox with azole anti-fungals (for example, ketoconazole and itraconazole), decreases the breakdown by cytochrome P450 3A. This causes an increased amount of Alprox in the blood. The intake of Alprox with ketoconazole, itraconazole, or other azole-type antifungals is not recommended.
There may be an interaction of Alprox with HIV protease inhibitors (ritonavir), which are used to treat viral infection. The use of ritonavir with Alprox results in decreased Alprox elimination from the body and enhanced clinical effects. When HIV protease inhibitors are used with Alprox, a dose-adjustment or discontinuation of Alprox is needed.
Alprox Tablet may interact with liver enzyme (CYP3A4) inducers. The inducers of this enzyme may increase the breakdown of Alprox.
Alprox Tablet interacts with isoniazid or paroxetine, which are used to treat infection and depression respectively. While using Alprox with isoniazid and paroxetine, caution is recommended.
There may be an interaction of Alprox with ergotamine, amiodarone, nicardipine, cyclosporine, and nifedipine, which are used to treat migraine type headache, irregular heartbeat, high blood pressure, to prevent organ rejection and certain types of chest pain respectively. While using Alprox with ergotamine, amiodarone, nicardipine, cyclosporine, or nifedipine caution should be taken.
Alprox Tablet may interact with carbamazepine, which is used to treat seizures. The use of Alprox with carbamazepine can increase the breakdown of Alprox and thus decrease Alprox level in the blood.
This page does not contain all the possible interactions of Alprox Tablet. Share a list of all medicines that you use with your doctor and pharmacist. Do not start, stop, or change the dose of any medicines without the approval of your doctor.
