Common side effects of Symjepi include swelling, warmth, or tenderness at the site of injection, anxiety, and restlessness.

Symjepi Precautions
Symjepi is used as emergency supportive therapy and is not intended as a substitute for immediate medical care. Seek immediate medical or hospital care when using Symjepi. More than two consecutive doses of Symjepi should only be given under direct medical supervision.
Serious side effects have been reported with Symjepi including the following:
- Injection-related problems. Symjepi should only be injected into the middle of the outer thigh. Hold the leg firmly during injection and limit movement prior to it to minimize the risk of injection-related injury.
- Do not inject intravenously (into a vein). When injected into a vein, epinephrine may cause cerebral hemorrhage (stroke) due to a sharp rise in blood pressure.
- Do not inject into the buttock. Injection into buttock may not provide effective treatment of anaphylaxis. Also, it might cause gas gangrene (bacterial infection).
- Do not inject into digits, hands or feet. Injection into the digits, hands or feet may result in loss of blood flow to that area.
- Serious infections at the injection site. Symjepi injections may cause serious skin and soft tissue infections, including necrotizing fasciitis and gas gangrene. Do not inject Symjepi into buttock as it increases the risk of serious skin and soft tissue infections. Seek medical care if you develop signs or symptoms of infection, such as persistent redness, warmth, swelling, or tenderness.
- Allergic reactions associated with sulfite. Metabisulfite is one of the ingredients of Symjepi and can cause serious allergy or other emergency situation when given to sulfite-sensitive patients.
- Disease interactions. Symjepi should be administered with caution to patients with
- heart disease including cardiac arrhythmias (heart rhythm abnormalities), coronary artery disease (damage of heart's major blood vessels), and/or high blood pressure.
- hyperthyroidism (high thyroid hormone levels)
- diabetes (high blood sugar levels)
- parkinson's disease (a disorder of nervous system that causes movement problems)
- Symjepi should be administered with caution to elderly and pregnant patients.

Symjepi and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
Symjepi and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if Symjepi crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Symjepi.
