What is Symmetrel (Amantadine Hydrochloride) used for?

Symmetrel (Amantadine Hydrochloride) is an oral antiviral medication used to prevent or treat influenza A. It operates by slowing or stopping the reproduction of virus cells allowing the immune system to control the infection. This action also makes it useful for preventing outbreaks of shingles or the symptoms of Parkinson's disease such as stiff movements or tremors. Your physician may prescribe it for other unlisted purposes, as well.

How should I use Symmetrel (Amantadine Hydrochloride)?

Follow your physician's instructions while using Symmetrel (Amantadine Hydrochloride) to get the most effective results from treatment. One tablet is typically taken once or twice daily, but your individual dosage will depend on the condition being treated, your health condition, and the severity of your symptoms. These should be swallowed with a glass of water and can be taken with or without food, but a meal should be eaten before application if you get an upset stomach. Never change the form of the tablets before use to avoid unintentionally destroying or changing their effects. Ask your pharmacist or physician any questions you have about the medication to ensure the correct administration.

What are the side effects of Symmetrel (Amantadine Hydrochloride)?

Some patients using Symmetrel (Amantadine Hydrochloride) have reported experiencing side effects such as:

  • Headache
  • Drowsiness or dizziness
  • Dry mouth or dry nose
  • Nausea, upset stomach, diarrhea, or constipation
  • Nervousness
  • Insomnia or nightmares
  • Confusion or loss of coordination

More serious side effects that may require emergency medical attention include swelling, hallucinations, urinary retention, tremors, irregular heartbeats, trouble breathing, or unusual behavior changes. Immediately inform your physician about any intense or worrying side effects that occur to make sure the correct adjustments are made to your regimen to prevent further complications from occurring.

Please Note

Symmetrel (Amantadine Hydrochloride) should not be used to treat patients with a history of stomach ulcers, history of seizures, or severe kidney disease. Before beginning treatment, it is also suggested to inform your physician if you have a history of cardiovascular disease, congestive heart failure, psychiatric disorders, hallucinations, confused states, or liver or kidney problems as these conditions may cause unexpected problems during treatment.

Strictly follow all instructions provided to you by your physician or pharmacist while using Symmetrel (Amantadine Hydrochloride). Optimum and safe dosage can differ based on the patient and the condition being treated.

As this medication may be unsafe for certain patients, it is essential you always inform your physician if you are pregnant or breastfeeding, as well as if you have any allergies, other illnesses, or ongoing health conditions, and if you are taking any other form of medication, supplements, or herbal products.

Immediately seek emergency medical care if you have an allergic or hypersensitive reaction. Common signs of a reaction include hives, swelling, skin rashes, chest pains, as well as trouble breathing or swallowing.
