The immediate effects of AAS in the brain are mediated by their binding to androgen (male sex hormone) and estrogen (female sex hormone) receptors on the surface of a cell. This AAS–receptor complex can then shuttle into the cell nucleus to influence patterns of gene expression. Because of this, the acute effects of AAS in the brain are substantially different from those of other drugs of abuse. The most important difference is that AAS are not euphorigenic, meaning they do not trigger rapid increases in the neurotransmitter dopamine , which is responsible for the “high” that often drives substance abuse behaviors. However, long-term use of AAS can eventually have an impact on some of the same brain pathways and chemicals—such as dopamine, serotonin, and opioid systems—that are affected by other drugs of abuse. Considering the combined effect of their complex direct and indirect actions, it is not surprising that AAS can affect mood and behavior in significant ways.

Because steroids are hormones, patients who use them for long periods of time must be carefully monitored. The most common side effects are: weight gain; thinning of the skin; upset stomach; muscle weakness in the thighs, shoulders, and neck; “masking” or hiding a fever; mood swings; insomnia; pneumonia; and increased blood sugar levels (especially in patients with diabetes). Steroids can also interact with some seizure medications, either raising or lowering the seizure medicine levels in the blood, which can affect their effectiveness. Your doctor can explain other side effects that may occur with steroid use.

Raynaud’s phenomenon is a condition in which the blood vessels in the hands and/or feet go into spasm, causing restricted blood flow. Lupus-related Raynaud’s usually results from inflammation of nerves or blood vessels and most often happens in cold temperatures, causing the tips of the fingers or toes to turn red, white, or blue. Pain, numbness, or tingling may also occur. People with Raynaud’s phenomenon should try to avoid cold conditions, and, if necessary, should wear gloves or mittens and thick socks when in an air-conditioned area.
