As with most drugs, you can take your missed dose of Allegra D once you remember to. However, skip it if it is almost time for your next dose.
Possible side effects that you may encounter are similar to that of the flu: headache, upset stomach, nausea, insomnia. If they persist, you may call your doctor at once. You may experience other side effects such as dizziness, drowsiness, fainting, fever and palpitation. These are possible but very improbable.

A large overdose of the drug can be dangerous causing most of the possible side effects along with giddiness, sweating, muscle tension, precordial pain, restlessness, tachycardia and anxiety. Serious cases may cause delusions and hallucinations with the worst leading to cardiac arrhythmias, circulatory collapse, coma, convulsions and respiratory failure.
Use caution or completely avoid driving, operating machinery or performing any activity which can either be dangerous or may require you to be alert. Allegra-D can cause dizziness. Antacids with magnesium or aluminium can decrease the drug’s effects.
