Do not get up too fast if you sit or lie as it may cause dizziness. Avoid drinking alcohol and consult your doctor if you drink grapefruit juice as its interaction with Verampil may lead to potentially dangerous effects.

Some other conditions require careful use of Verampil. Do not take the medication unless it is prescribed to you and take it only as it is administered by your physician.

• chest pain,
• heart attacks or strokes,
• significant water retention,
• especially accompanied by difficulty breathing,
• signs of very low blood pressure,

Dangerous heart slowing may appear if Verampil is taken concurrently with a beta-blocker. This medication increases the concentration of digoxin, theophylline, carbamazepine, myorelaxants in blood so levels of these drugs should be monitored to avoid toxicity. In some patients blood levels of lithium maybe reduced.
If you missed a dose take it as soon as you remember, but not if it is almost time of the next intake by your schedule. If so skip the missed dose. Do not try to compensate for a missed dose by taking an extra one.
If you suspect that you took too much of Verampil and feel slow heartbeat and fainting seek for immediate medical attention.
The medication should be stored at room temperature 15-30 C (59-86 F) in a light-resistant box.
