Heroin Side Effects, Allergic

Most patients contact us because of their experience with serious Heroin side effects from habitual use. Allergic reactions to opiate-based drugs can sometimes prove fatal. Contact your doctor if you experience:

Severe allergic reactions

• Difficulty breathing
• Hives
• Itching
• Rash
• Swelling of the mouth, face, lips, or tongue
• Tightness in the chest
  

The risk of convulsions may increase in patients using opiates, who also have a history of:

• Alcoholism and/or withdrawal
• Central nervous system disorders or infections
• Drug dependency, addiction or withdrawal
• Epilepsy, fits, convulsions, and seizures
• Head trauma or surgery
• Metabolic diseases and disorders

Persistent Heroin side effects may be precursors indicating an acute Heroin overdose . Different people will react differently to various medications and can experience different symptoms, or to varying degrees.

Please contact your pharmacist, doctor, or emergency room for urgent care if these Heroin side effects or other unlisted Heroin side effects occur and persist.

Heroin Overuse

The number of available opiate receptors in the body decreases with continued Heroin use, which leads to tolerance and dependence.

Recreational intravenous administration of Heroin carries the additional dangers of non-sterile needle use and possible contraction of hepatitis, HIV, fungal heart inflammation (endocarditis), infected abscesses (pus cavities), and contaminant poisons from ‘cut’ (diluted) Heroin, among other health risks besides just Heroin side effects.

Other serious health concerns with opiate-based medication:

• Intravenous injection, especially of Heroin, is particularly dangerous due to the possibility for lethal respiratory or cardiac arrest.

Additional psychological signs of Heroin and opiate overuse, which indicate dependency or addiction, involve:

• Depression.
• Loss of libido.
• Disinterest in simple things of life.
• Indifference toward family and friends.
• Loss of professional or personal drive.

Please seek urgent medical care immediately if your condition worsens, or in the event of an adverse allergic reaction.
