Modafinil is a pain reliever used to treat drowsiness associated with narcolepsy.
Off-label Modafinil is widely used to avoid the need for sleep. It is also used over-the-counter to combat generalized fatigue unrelated to sleep deprivation, for example in the treatment of attention deficit hyperactivity disorder (ADHD) and as an adjunct to antidepressants (especially in people with significant residual fatigue).
Drug side effects.
As a general rule, Modafinil does not cause serious side effects. Sometimes, against the background of very high doses of the drug or due to individual intolerance, side effects such as:
- sleep disorders;
- pain in the lower back;
- Chest pain;
- accelerated heartbeat;
- decrease/increase in blood pressure;
- changes in mood;
But this is not a complete list of possible side effects.
While most people will not experience any side effects from taking this medication, we recommend consulting a doctor before taking it.
Can you feel tired on modafinil?
In general, after taking Modafinil, a person feels more active and able to perform more tasks. However, in rare cases, the drug can cause side effects such as fatigue.
This can happen for several reasons:
- development of tolerance to stimulant drugs (occurs when a person uses high doses of modafinil for a long time, with time having to increase the dose to feel the effect);
- in the context of the interaction of modafinil with other drugs;
- if modafinil previously worked and over time its effectiveness diminished and conversely fatigue was felt, this could be a sign of developing attention deficit hyperactivity disorder.
Is there an overdose of Modafinil?
Symptoms of an overdose can only occur if a person exceeds the maximum allowable daily intake of the drug. That is, take more than 400 mg of modafinil.
If you use too high a dose of modafinil, symptoms such as side effects occur. This is seen anxiety, agitation, restlessness, confusion, sleep disturbances, diarrhea, tachycardia, hallucinations, nausea, tremors, chest pain and some other symptoms.
