Would 100mg of Lexapro be an overdose?

There is no definitive 'too much' for an overdose of Lexapro. Some can have an overdose experience on doses that are therapeutic for most. Also, with typical SSRI's.. they are considered relatively safe for the mentally unstable. This means that if one were suicidal that an attempt at taking ones life with an abundance of 'lexapro' or most any other typical SSRI will not cause death.

If taken as prescribed by your doctor the chances for overdose are very slim, and if an overdose does occur at a regular prescribed dose -- The effects are usually easily managed and will go away.

Symptoms of overdose would include (but not limited to) : nausea, vomiting, tremor, sweating, rapid heartbeat, confusion, dizziness, seizures, and coma. Obviously the latter being very rare. Also the less severe of these symptoms are not completely indicative of overdose. ie: If one is dizzy or confused it does not mean they are experiencing an overdose from the SSRI in question. It is the combination of symptoms that provide an accurate conclusion.

To prevent overdose it is important one takes the medication as prescribed, and if a dose is missed (forgotten) to not double up. Simple take the next scheduled dose. Less is more.

As with most SSRI's, they take several weeks to a month to begin to become fully effective. This is a 'loading' effect into the body. The drug builds up to some degree, and the body begins to agree with the chemical changes. This is why taking more at any time in an attempt to get 'more' of an effect is dangerous and inneffective. These medications do not work like most others. They are not instant, they are not something that can be dose titrated in a 24 hour time frame for change of helpful mediation. Dose titration must be done over weeks of time to produce desired results.
