If you received specific disposal instructions from your healthcare provider (e.g., doctor, pharmacist) for your unused or expired medicine, you should follow those instructions to dispose of your medicine. The best disposal option is to find a drug take back location, which may be found in retail, hospital, or clinic pharmacies; and/or law enforcement facilities.

FDA recognizes that the recommendation to flush a few specific medicines when a take back program is not readily available raises questions about the impact of the medicines on the environment and the contamination of surface and drinking water supplies.

FDA believes that the known risk of harm, including toxicity and death, to humans from accidental exposure to medicines on the flush list far outweighs any potential risk to human health and the environment from flushing these unused or expired medicines. Remember only flush medicines on the flush list if a take-back option is not readily available. FDA will continue to conduct risk assessments as a part of our larger activities related to the safe use and disposal of medicines.

FLUSH LOGS, FLUSH BINARY LOGS, FLUSH TABLES WITH READ LOCK (with or without a table list), and FLUSH TABLES tbl_name ... FOR EXPORT are not written to the binary log in any case because they would cause problems if replicated to a replica.

Re-reads the privileges from the grant tables in the mysql system schema. As part of this operation, the server reads the global_grants table containing dynamic privilege assignments and registers any unregistered privileges found there.

Frees memory cached by the server as a result of GRANT, CREATE USER, CREATE SERVER, and INSTALL PLUGIN statements. This memory is not released by the corresponding REVOKE, DROP USER, DROP SERVER, and UNINSTALL PLUGIN statements, so for a server that executes many instances of the statements that cause caching, there is an increase in cached memory use unless it is freed with FLUSH PRIVILEGES.

The descriptions here that indicate tables are flushed by closing them apply differently for InnoDB, which flushes table contents to disk but leaves them open. This still permits table files to be copied while the tables are open, as long as other activity does not modify them.

With a list of one or more comma-separated table names, this operation is like FLUSH TABLES with no names except that the server flushes only the named tables. If a named table does not exist, no error occurs.

FLUSH TABLES WITH READ LOCK acquires a global read lock rather than table locks, so it is not subject to the same behavior as LOCK TABLES and UNLOCK TABLES with respect to table locking and implicit commits:

UNLOCK TABLES implicitly commits any active transaction only if any tables currently have been locked with LOCK TABLES. The commit does not occur for UNLOCK TABLES following FLUSH TABLES WITH READ LOCK because the latter statement does not acquire table locks.

Beginning a transaction causes table locks acquired with LOCK TABLES to be released, as though you had executed UNLOCK TABLES. Beginning a transaction does not release a global read lock acquired with FLUSH TABLES WITH READ LOCK.

The operation first acquires exclusive metadata locks for the tables, so it waits for transactions that have those tables open to complete. Then the operation flushes the tables from the table cache, reopens the tables, acquires table locks (like LOCK TABLES ... READ), and downgrades the metadata locks from exclusive to shared. After the operation acquires locks and downgrades the metadata locks, other sessions can read but not modify the tables.

This operation applies only to existing base (non-TEMPORARY) tables. If a name refers to a base table, that table is used. If it refers to a TEMPORARY table, it is ignored. If a name applies to a view, an ER_WRONG_OBJECT error occurs. Otherwise, an ER_NO_SUCH_TABLE error occurs.

This FLUSH TABLES variant enables tables to be flushed and locked in a single operation. It provides a workaround for the restriction that FLUSH TABLES is not permitted when there is an active LOCK TABLES ... READ.

This operation does not perform an implicit UNLOCK TABLES, so an error results if you perform the operation while there is any active LOCK TABLES or use it a second time without first releasing the locks acquired.

This operation requires the FLUSH_TABLES or RELOAD privilege. Because it acquires locks on tables in preparation for exporting them, it also requires the LOCK TABLES and SELECT privileges for each table.

It acquires shared metadata locks for the named tables. The operation blocks as long as other sessions have active transactions that have modified those tables or hold table locks for them. When the locks have been acquired, the operation blocks transactions that attempt to update the tables, while permitting read-only operations to continue.

InnoDB supports FOR EXPORT for tables that have their own .ibd file file (that is, tables created with the innodb_file_per_table setting enabled). InnoDB ensures when notified by the FOR EXPORT operation that any changes have been flushed to disk. This permits a binary copy of table contents to be made while the FOR EXPORT operation is in effect because the .ibd file is transaction consistent and can be copied while the server is running. FOR EXPORT does not apply to InnoDB system tablespace files, or to InnoDB tables that have FULLTEXT indexes.

When notified by FOR EXPORT, InnoDB writes to disk certain kinds of data that is normally held in memory or in separate disk buffers outside the tablespace files. For each table, InnoDB also produces a file named table_name.cfg in the same database directory as the table. The .cfg file contains metadata needed to reimport the tablespace files later, into the same or different server.

When the FOR EXPORT operation completes, InnoDB has flushed all dirty pages to the table data files. Any change buffer entries are merged prior to flushing. At this point, the tables are locked and quiescent: The tables are in a transactionally consistent state on disk and you can copy the .ibd tablespace files along with the corresponding .cfg files to get a consistent snapshot of those tables.

After you are done with the tables, use UNLOCK TABLES to release the locks, LOCK TABLES to release the locks and acquire other locks, or START TRANSACTION to release the locks and begin a new transaction.

Doing some spring cleaning and clearing out your medicine cabinet? Stop before you flush old or unwanted prescription or over-the-counter medications down the toilet or drain. These pharmaceuticals can pollute our water and unintentionally expose us to the chemicals in these medications.

Studies have found that medicines flushed down the drain can contaminate our lakes and streams, which can hurt fish and other aquatic wildlife, and end up in our drinking water. Some medications, such as hormones and antidepressants, include endocrine disrupting compounds that interfere with the reproduction and normal growth of many aquatic species, such as frogs and fish.

In addition to the environmental impacts, prescription drugs in home cabinets are a significant cause of accidental poisoning. These drugs are also highly susceptible to misuse and abuse. Studies show that people who abuse prescription drugs often obtained them from family and friends, including from the home medicine cabinet.

When medications are flushed down a toilet or drain, they enter the wastewater treatment system, which cleans up the water. Unfortunately, many of these treatments systems are not designed to remove medications.

There are more than 300 medication collection boxes located at law enforcement facilities and pharmacies in Minnesota. These collection sites do not charge any disposal fees. Collection sites accept all medicines from households, including prescription, over-the-counter, liquid, solid, and pet medicines.

Incineration at a permitted waste-to-energy facility is the best method for destruction of household pharmaceuticals. If you know your garbage goes to an incinerator, you can safely dispose of your medications using the instructions below.

Truly flushable items are ones that: break into small pieces quickly, are not buoyant, and only contain materials which will readily degrade in a range of natural environments (like paper, not plastic).
