What is SINEMET used for?

SINEMET is a dopa decarboxylase inhibitor / dopamine replacement and is used to treat the following:

  • Parkinson’s disease (PD)
  • Parkinsonism (conditions that cause people to have signs and symptoms of PD, including slowness, stiffness, shakiness, and imbalance)
How does SINEMET work?

How does SINEMET work?

SINEMET is a combination of two medications: carbidopa and levodopa. By working together, these medications help relieve symptoms of Parkinson’s disease (PD), which occur due to low dopamine levels in the brain. Levodopa is a dopamine replacement. Levodopa travels into your brain, where it’s converted into dopamine. It helps relieve PD symptoms by restoring dopamine in your brain. Carbidopa is a dopa decarboxylase inhibitor. Dopa decarboxylase is a protein in your body that breaks down levodopa before it can travel into your brain.

By blocking this protein, carbidopa prevents levodopa from breaking down. This raises the level of levodopa in your body and allows more levodopa to travel into your brain to be converted into dopamine. Levodopa and dopamine can then reach and remain at higher levels in your brain, which enhances levodopa’s ability to relieve PD symptoms.

How do I take SINEMET?

How do I take SINEMET?

SINEMET is typically started at 25 mg/100 mg (carbidopa/levodopa) by mouth 3 times per day. Your healthcare provider will slowly raise your dose until your symptoms of PD are relieved.

Is it safe for me to take SINEMET?

Is it safe for me to take SINEMET?

SINEMET is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you. Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with SINEMET. These inhibitors must be discontinued at least two weeks prior to initiating therapy with SINEMET.

SINEMET Common Side Effects

SINEMET Common Side Effects

Common side effects of SINEMET:

  • Involuntary movements
  • Nausea
SINEMET Serious Side Effects

SINEMET Serious Side Effects

Serious side effects are rare with SINEMET. Contact your healthcare provider immediately if you experience any of the following.

  • Neuroleptic malignant syndrome (NMS): very high fevers, confusion, irregular pulse, sweating, muscle stiffness, changes in blood pressure
Effects of other drugs, drug classes and over-the-counter products on SINEMET

Effects of other drugs, drug classes and over-the-counter products on SINEMET

The following medications may interact with SINEMET:

  • Symptomatic postural hypotension has occurred when carbidopa levodopa preparations were added to
  • the treatment of patients receiving some antihypertensive drugs
  • Concomitant therapy with selegiline and carbidopa levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa levodopa alone
  • There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and carbidopa levodopa preparations
  • Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with SINEMET should be carefully observed for loss of therapeutic response
  • Use of SINEMET with dopamine-depleting agents (e.g., reserpine and tetrabenazine) or other drugs known to deplete monoamine stores is not recommended
  • SINEMET and iron salts or multivitamins containing iron salts should be coadministered with caution. Iron salts can form chelates with levodopa and carbidopa and consequently reduce the bioavailability of carbidopa and levodopa

How do I use the SINEMET ® PAP to obtain my medication?

Once you are enrolled in the program you will be advised by the pharmaceutical company how they will make supplies to you. In most cases, they will ship the medication through their nominated mail-order pharmacy, directly to you.

Can I buy my SINEMET ® from Canada?

Americans pay at least twice as much (in fact 218%) on prescription medications than individuals in other countries, like Canada. The reason why Canada drugs are cheaper is that Canada regulates its prescription medication drug prices (the Patented Medicines Prices Review Board) meaning that consumers pay less for their SINEMET®. This prevents pharmaceutical patentees from charging excessive prices.

As well, many Canadian drugs are likely produced by exactly the same companies in the same factories, as US prescription drugs.

We have partnered with Prescription Help in Canada that carries thousands of branded and generic medications. If there is an option for SINEMET® from Canada, then we will provide this as an Rx savings option to you.

Is it safe for me to buy my SINEMET ® from Prescription Help, Canada?

If you purchase SINEMET® from Canadian Prescription Help, then there is little reason to worry about safety since it is likely that the drugs will be the same ones you would get from your American drugstore, and would have undergone the same rigorous testing as the American counterparts. Canada drugs are regulated for safety, efficacy and quality by Health Canada, which is the Canadian equivalent of the Food and Drug Administration (FDA). If you are unsure, you can discuss this option with your physician, especially if you find it difficult affording your medications and may therefore risk not being treated.

Rest assured, NowPatient has done thorough due diligence on Prescription Help, to ensure that the service is adequately licensed, regulated and safe.

We have checked and verified that Prescription Help:

  • Is a licensed pharmacy in Canada.
  • Will only fill your SINEMET® if you have a valid prescription.
  • Has a licensed pharmacist on staff to answer your questions.
  • Does not send medicine that looks different than what you receive at your usual drug store, nor does it arrive in packaging that is damaged, in a foreign language, has no expiration date, or is expired.
  • Does not charge you for products that you never ordered or received.
  • Provides clear written protections for your personal and financial information, including credit card numbers.
  • Maintains the highest standards of data security and compliance.
  • Does not sell your information to other websites.
  • Does not supply controlled substances.
  • Does not supply any products on an FDA Import Alert.
  • Quantities are restricted to a maximum of 3 month's supply for international orders.
  • Publishes contact information on website for customer service.

Is ordering SINEMET ® from a Canadian Pharmacy legal?

Although it is technically not legal for individuals to import prescription drugs, It is notable that U.S. government officials have stated that individuals who procure non-controlled prescription drugs from Canada or other foreign sources for up to a three-month supply for their own use are not pursued or prosecuted. There are hundreds of thousands of American patients who have used or continue to use Canadian pharmacies to procure their medications at significant discounts. Often the price of medications can be the difference between getting treated or not being treated.

How do I place an order for SINEMET ® from Prescription Help, Canada?

If your medication is available from our partner Canadian Pharmacy, then we will show it as an option. You can search for the product by pack size, strength or form and then see the price for SINEMET®. If you are happy with the price, you can proceed to the checkout. This will take you to the Prescription Help website, from where you can complete the process. Prescription Help is not connected to NowPatient other than as an affiliate partner which offers services that may benefit NowPatient users. It is not insurance, any payments are strictly cash and are considered out-of-pocket.

What should I do if I take too much SINEMET ®?

Call your doctor right away or seek immediate medical attention if your symptoms do not improve or they become worse after using SINEMET®. You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource if you think you've used too much SINEMET®. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.
