The most serious adverse side effect of injectables is allergic reactions and infections.
Most reactions at the injection site from injectables are mild and cause temporary redness, tenderness and itching which often resolve within a few days.
But if these effects and symptoms last too long or get worse or last longer that a few days you should see a doctor or seek medical care, especially if the symptoms are accompanied by difficulty breathing, pus or fever.
The most serious risk that is associated with having dermal filler injectables is accidental injection into a blood vessel.
If the dermal filler is injected into a blood vessel it can result in death of tissue also called skin necrosis, blindness or even a stroke.
The types of diseases that are spread and can be spread by using injected syringes and injectables are fungal diseases, bacterial diseases, hepatitis B and even Hepatitis C.
HIV can also be possibly spread by using injected syringes, if the syringes are reused on more than one person or to access any vials that are shared between patients.
Blood borne diseases can be spread through sharing the same needles and injected syringes.
So it's important to never share injected syringes or needles with anyone even if you know them or even if they are family.
A new syringe or needle should always be used even if it's on yourself and never share needles with others and always dispose of the used needles and syringes properly and safely to avoid someone else getting pricked up the needles or syringes which can also transmit any disease that way as well.
Always wash your hands after using a syringe or needle and especially when injecting someone else and if injecting someone else with an injected syringe or other needle or giving someone an IV always wear gloves.
Unsafe injection practices may result in serious consequences like the transmission of bloodborne pathogens such as hepatitis C virus (HCV), hepatitis B virus (HBV), and human immunodeficiency virus (HIV).
Viral hepatitis, HIV, and other blood-borne pathogens can easily spread through injection drug use if people use needles, syringes, or other injection materials that were previously used by someone who had one of these infections.
