Side effects may vary depending on the medicine you take, but common ones include:

• Nausea.
• Dry mouth.
• Loss of appetite.
• Diarrhea or constipation.
• Sexual problems (loss of desire, erection problems).
• Headaches.
• Trouble falling asleep, or waking a lot during the night.
• Feeling nervous or on edge.
• Feeling drowsy in the daytime.

Most side effects are temporary and will go away after you take the medicine for a few weeks. But some (such as dry mouth, constipation, and sexual problems) may continue. If you have questions or concerns about your medicines, talk to your doctor.

Different medicines may cause different side effects. Learn more about the side effects of:

• Selective serotonin reuptake inhibitors (SSRIs), such as Paxil, Prozac, and Zoloft.
• Tricyclic and tetracyclic antidepressants, such as amitriptyline, maprotiline, and Pamelor.
• Other antidepressants, such as Effexor, Remeron, and Wellbutrin.
• Monoamine oxidase inhibitors (MAOIs), such as Marplan, Nardil, and Parnate.

Continue to Why?

Most antidepressants cause minor side effects that go away or improve in the first few weeks of treatment. If you keep taking your medicine, there is a good chance that you will start to feel less depressed and the side effects will decrease. Most people feel that the benefits of antidepressants are well worth the price of living with some side effects.

If the side effects continue to bother you, talk to your doctor. You might be able to try a different dosage or a different medicine.

Even if you are going to change medicines, you should not suddenly quit taking your current antidepressant. That could cause withdrawal symptoms or make your depression come back. Work with your doctor to make the switch safely. This may require slowly reducing the dose of the old medicine before you start the new medicine.

Common side effects

Try these tips to help you manage some of the common side effects of antidepressants.

Constipation

• Eat bran and other whole-grain cereals and high-fibre fruits and vegetables, such as apples, prunes, beans, and broccoli.
• Drink plenty of fluids.

Daytime drowsiness

• This problem usually goes away as your body adjusts to the medicine.
• Ask your doctor if you can take your medicine at bedtime.
• Do not drive or operate heavy equipment when you feel drowsy.

Diarrhea

• Eat mild, low-fibre foods, such as applesauce, rice, and yogurt.
• Avoid spicy and high-fat foods until you feel better.

Dizziness

• Get up slowly from sitting or lying down.

Dry mouth

• Chew sugarless gum or suck on sugarless candy.
• Take frequent sips of water throughout the day.

Headaches

• These usually will go away as your body adjusts to the medicine.
• Ask your doctor what medicine you can take for a headache.

Loss of appetite

• Try to eat more often. Have healthy snacks between meals.
• Include favourite foods at each meal.
• Take a walk before you eat. This may make you more hungry.

Nausea

• Eat several smaller meals a day rather than two or three large meals.
• Try peppermint candy or gum. Peppermint can help settle your stomach.

Feeling nervous or on edge

• This will probably go away soon.
• If it lasts, ask your doctor if you can reduce your dose.

Sexual problems

• Ask your doctor if you can take a lower dose.
• Ask your doctor if there is another medicine you can try.

Sleep problems

• Avoid caffeine, nicotine, and alcohol.
• Don't exercise in the late afternoon or evening.
• Keep your bedroom quiet, dark, and cool, and use a sleep mask and earplugs.
• If these problems don't go away over time, ask your doctor about reducing your dose.
• Change the time of day you take your medicine to the morning.

Serious side effects

Serious side effects don't happen often, but you should be aware of them. Call your doctor right away if you or anyone who takes antidepressants has:

• Chest pain.
• Hives, shortness of breath, trouble swallowing, swollen lips, or other signs of a serious allergic reaction.
• Warning signs of suicide, such as talking or writing about death, giving away belongings, or withdrawing from family and friends.
• Manic behaviour, such as having very high energy, sleeping less than normal, being impulsive, or being grouchy or restless.

Cautions

• Be sure your doctor knows about any other health problems you have and whether you are allergic to any drugs. This can affect what medicine your doctor prescribes for you.
• Tell your doctor about any medicines you take regularly, including over-the-counter drugs, vitamins, and herbs. This can help you avoid harmful drug interactions.
• Do not take any other medicines without talking to your doctor first. Even common medicines such as ASA and some vitamins and herbs can cause problems if you use them while you are taking antidepressants.
• Do not drink alcohol or use illegal drugs. They can make side effects worse.
